Critical thinking in everyday life.

by Winston Sieck updated September 19, 2021

Have you ever been listening to one of your teacher’s lessons and thought that it had no relevance to your own life?

You’re not alone. Just about every student has felt the same way.

Sure, you use critical thinking skills in the classroom to solve word problems in math, write essays in English, and create hypotheses in science.

But how will you use critical thinking in everyday life?

First, keep in mind that critical thinking is simply a “deliberate thought process.”

Basically, it means that you are using reason and logic to come to a conclusion about an issue or decision you are tangling with.

And clear, sound reasoning is something that will help you every day.

To help you make the leap from classroom to real world, here are 3 concrete examples of critical thinking in everyday life.

Fake News vs. Real News

Take a moment to reflect on your media skills. Do you think you have what it takes to sort out a real news source from a piece of clever advertising?

According to a recent study from Stanford University, a whopping 82% of the teens surveyed could not distinguish between an ad labeled “sponsored content” and a legitimate news story.

Part of the problem may come from schools cutting back on formal instruction of critical thinking skills and an assumption that today’s “digital native” teens can automatically tell the difference without practice or instruction.

You are good at lots of things. But, you know, you’ve practiced those things you’re good at. So, how can you practice telling fact from fiction?

One way (outside of school) is to chat with your family and friends about media sources. Find out how they stay informed, and why they choose those outlets. Ask each other routine questions for evaluating sources .

Do your Friends Know Everything?

It’s tempting to believe that the world begins and ends with your friends. Don’t get me wrong. Friends are definitely important. However, it pays to reflect a little on how a group influences our lives.

To practice critical thinking in everyday life, take a close look at your group of friends. Are there things that are “forbidden” in your social circle? Are you expected to act a certain way, dress a certain way?

Think a certain way?

It’s natural that when a group defines something as “cool”, all the people in the group work to fit into that definition. Regardless of what they individually believe.

The problem is that virtually every situation can be defined in multiple ways. What is “dumb” to one person may be “cool” to another.

Develop your ability to redefine the way you see the world around you. On your own terms.

Find a time when your friend group sees the negative in a situation. Is there a positive way to view it instead? Or at least a way that makes it seem not quite so bad?

You may not be ready to speak up with your independent view. And that’s ok. Just practice thinking differently from the group to strengthen your mind.

Critical Thinking in the Driver’s Seat

One of the core critical thinking skills you need every day is the ability to examine the implications and consequences of a belief or action. In its deepest form, this ability can help you form your own set of beliefs in everything from climate change to religion.

But this skill can also save your life (and your car insurance rate) behind the wheel.

Imagine you are cruising down the freeway when your phone alerts you to an incoming text message. The ability to examine your potential actions and their accompanying consequences will help you make the best choice for how to handle the situation.

Do you look at the text and risk getting into an accident? Do you wait and risk not responding to an urgent matter? Or do you pull over to look at the text and risk being late for your appointment?

The same skill can be applied when you are looking for a place to park, when to pull onto a busy street, or whether to run the yellow light.

Better yet, the more practiced you are at looking at the implications of your driving habits, the faster you can make split second decisions behind the wheel.

Why Critical Thinking in Everyday Life Matters

Literally everyone can benefit from critical thinking because the need for it is all around us.

In a philosophical paper , Peter Facione makes a strong case that critical thinking skills are needed by everyone, in all societies who value safety, justice, and a host of other positive values:

“Considered as a form of thoughtful judgment or reflective decision-making, in a very real sense critical thinking is pervasive. There is hardly a time or a place where it would not seem to be of potential value. As long as people have purposes in mind and wish to judge how to accomplish them, as long as people wonder what is true and what is not, what to believe and what to reject, strong critical thinking is going to be necessary.”

So, in other words, as long as you remain curious, purposeful, and ambitious, no matter what your interests, you’re going to need critical thinking to really own your life.

Why and How to Use Critical Thinking in Everyday Life

Written by Argumentful

Critical thinking is a helpful skill that allows you to analyze information and make informed decisions. It’s all about taking a step back and evaluating information objectively, considering multiple perspectives, and making sound judgments based on evidence. With critical thinking, you can tackle problems with confidence, communicate your thoughts and ideas clearly, and reduce the influence of emotions, biases, and misinformation. Plus, by using critical thinking, you can continue to grow and develop as a person by questioning your own beliefs and perspectives.

Elder and Paul’s article “ Critical Thinking: The Nature of Critical and Creative Thought ” argues that critical thinking is essential for success in everyday life. They explain that critical thinking involves analyzing and evaluating information, as well as generating new ideas and perspectives.

Overall, critical thinking is a valuable tool for all of us to navigate the complex and ever-changing world we live in.

Here are some examples of using critical thinking in our daily lives.

EXAMPLES OF CRITICAL THINKING IN EVERYDAY LIFE

Using critical thinking in making smart health choices.

When it comes to taking care of yourself, using critical thinking to check the reliability of your sources and weigh the strength of the evidence can help you make better decisions for your health. If your doctor recommends a certain treatment or you come across a new health trend online, how can you be sure it’s the right choice for you? By using critical thinking, you can evaluate the credibility of sources, consider the evidence behind health claims, and make informed decisions that promote your well-being. Whether it’s choosing a fitness plan, exploring alternative therapies, or making dietary changes, critical thinking can help you take control of your health and make choices that are truly right for you. Don’t just blindly follow health advice, use critical thinking to help you make informed decisions for a healthier you!

Smart budgeting for a stable future

By taking a closer look at your income and expenses, you can use critical thinking to make informed decisions about your finances that will set you up for long-term stability. Should you invest now or should you save for a rainy day? What expenses can you cut back on to reach your financial goals? By using critical thinking, you can assess your financial situation, weigh the risks and benefits of different options, and make smart decisions that improve your financial stability.

Diane Halpern, award-winning educator and past president of the American Psychological Association, explains that critical thinking involves skills such as analyzing arguments, evaluating evidence, and making informed decisions.

Whether it’s creating a budget, setting savings goals, or making investments, critical thinking can help you make informed decisions that put you on a path towards financial security.

Problem solving at work

When you’re facing a problem on the job, using critical thinking can help you get to the bottom of it, weigh your options, and make a well-informed decision. Sometimes the solution may be simple, but other times, it can be complex and involve multiple factors. By using critical thinking, you can objectively analyze the problem, consider different perspectives, and determine the best course of action. This can lead to more effective problem-solving and decision-making in the workplace, helping you to tackle challenges and reach your goals with confidence.

Joe Lau, associate Professor at the University of Hong Kong explains how to identify and avoid common thinking errors, as well as how to use critical thinking to solve problems and make decisions.

So, when a problem arises on the job, don’t just react impulsively, take a step back and use critical thinking to find the best solution.

Fighting propaganda and misinformation with critical thinking

In today’s world with so much information at our fingertips, it’s important to use critical thinking skills to sort out credible sources from misinformation and propaganda. What if instead of relying on hearsay or biased sources, you could make informed decisions based on accurate information? That’s where critical thinking comes in handy. By evaluating the evidence and reasoning behind information, you can separate facts from fiction and make well-informed choices in all areas of your life. Whether it’s evaluating news articles, scientific studies, or even advertisements, critical thinking can help you navigate the maze of information and make informed decisions.

Making decisions about relationships

This might sound like we’re overthinking it, but even in the area of personal relationship you should use clear thinking. When making decisions about relationships, critical thinking can help you evaluate the strengths and weaknesses of your relationships, and make informed choices about the future. Should you get married? Should you end the relationship with a friend that is not supportive of your life choices and goals? By using critical thinking, you can weigh the pros and cons of these important decisions, and make choices that align with your values and aspirations. You can work out the decisions to these challenges methodically when you think critically.

Shopping and consumer decisions

By critically evaluating product claims, advertisements, and customer reviews, you can make informed purchasing decisions that meet your needs and budget. No longer will you be swayed by flashy advertising or a single glowing review. With critical thinking skills, you can objectively assess the validity of product claims, compare prices and features, and determine what truly matches your needs and budget. This can lead to more informed and confident purchasing decisions, saving you time and money in the long run. So, before you click “add to cart,” take a moment to critically evaluate the information available and make an informed choice!

Planning for the future

When making decisions about education, career, and retirement, critical thinking skills will help you evaluate options and make informed choices about the future. Will you continue living driven by others or will you make choices that align with your own goals and values? Weigh the pros and cons of different options, consider long-term consequences, and make decisions that are truly right for you!

Evaluating political information

In a politically charged world, you need critical thinking skills to evaluate political information, identify biases and propaganda, and make informed decisions about political issues. Who will you vote for in the next election? What political issues matter most to you? By using critical thinking, you can examine political information with a skeptical eye, consider multiple perspectives, and make justified choices based on facts and evidence. This can help you navigate the complex world of politics. So, don’t just take political information at face value, use your critical thinking skills to help you make informed and impactful decisions.

Making decisions about personal safety

If you are faced with safety concerns, critical thinking skills can also help you evaluate potential risks, make informed decisions, and take action to protect yourself and your loved ones. It’s always better to be prepared and proactive when it comes to safety. By using critical thinking, you can assess potential dangers, weigh your options, and take steps to ensure the well-being of yourself and those around you. Whether it’s preparing for natural disasters, navigating unfamiliar territory, or making decisions about personal safety, critical thinking can help you make choices that promote peace of mind and security.

Managing stress and emotions by thinking critically

By critically evaluating the root causes of stress and emotions, individuals can make informed decisions about how to manage their mental health and well-being. When was the last time you took a step back and evaluated what’s causing your stress and emotions? By using critical thinking, you can dig deeper into the root causes of your feelings and identify patterns or triggers. For example, maybe you notice that you feel stressed every time you have a big project due at work. By recognizing this pattern, you can take proactive steps to manage your stress, such as breaking down the project into smaller tasks or seeking support from a colleague. Similarly, if you’re feeling overwhelmed with negative emotions, critical thinking can help you evaluate what might be contributing to those feelings and determine steps you can take to improve your emotional well-being. For example, perhaps you’re feeling down because you’re not spending enough time with friends and family.

By recognizing this, you can make an effort to reach out and connect with loved ones, which can help boost your mood and emotional health.

By now you can probably guess the benefits of thinking critically. Here are some of them.

BENEFITS OF THINKING CRITICALLY

It’s important to also be aware of the many challenges that can divert us from thinking critically.

CHALLENGES TO CRITICAL THINKING

Challenges to critical thinking can arise from a variety of sources, such as emotions, biases, lack of information, and cognitive biases. However, these challenges can be overcome with practice and a few helpful tips.

• Emotional involvement : Emotions can cloud your judgment and make it difficult to think critically. To overcome this challenge, try to recognize when you are feeling emotional and take a step back to assess the situation objectively.
• Confirmation bias : Confirmation bias is the tendency to search for and interpret information in a way that confirms your existing beliefs. To overcome this, seek out diverse sources of information and try to consider multiple perspectives.
• Lack of information : When making decisions or evaluating arguments, it can be challenging to think critically when you don’t have all the necessary information. To overcome this challenge, gather information from credible sources and be transparent about what you don’t know.
• Cognitive biases : Cognitive biases refer to systematic errors in thinking that can impact our decision making and critical thinking skills. To overcome this, try to recognize and avoid common cognitive biases, such as the sunk cost fallacy or the availability heuristic.
• Fear of being wrong : Sometimes, fear of being wrong can prevent you from thinking critically. To overcome this challenge, try to approach situations with an open mind and embrace the opportunity to learn and grow.

Final words

In conclusion, critical thinking is a valuable skill that can be improved with practice and by being aware of the challenges that can impact our ability to think critically.

Richard Paul, an expert in critical thinking and co-founder of the Foundation for Critical Thinking, emphasized the importance of critical thinking in everyday life and provided several insights on how to apply it effectively.

One of the key things that Paul said about critical thinking for everyday life is that it involves actively and skillfully analyzing information and ideas, rather than simply accepting them at face value. He stressed the importance of questioning assumptions, considering different perspectives, and evaluating evidence in order to arrive at well-reasoned conclusions.

Paul also emphasized the need to be aware of our own biases and assumptions, as well as the influence of external factors such as media and advertising. He encouraged us to develop a habit of reflection and self-assessment, constantly questioning our own thought processes and seeking out new information and perspectives.

By recognizing these challenges and taking steps to overcome them, you can become a more effective critical thinker and make better decisions in your everyday life.

41+ Critical Thinking Examples (Definition + Practices)

Critical thinking is an essential skill in our information-overloaded world, where figuring out what is fact and fiction has become increasingly challenging.

But why is critical thinking essential? Put, critical thinking empowers us to make better decisions, challenge and validate our beliefs and assumptions, and understand and interact with the world more effectively and meaningfully.

Critical thinking is like using your brain's "superpowers" to make smart choices. Whether it's picking the right insurance, deciding what to do in a job, or discussing topics in school, thinking deeply helps a lot. In the next parts, we'll share real-life examples of when this superpower comes in handy and give you some fun exercises to practice it.

Critical Thinking Process Outline

Critical thinking means thinking clearly and fairly without letting personal feelings get in the way. It's like being a detective, trying to solve a mystery by using clues and thinking hard about them.

It isn't always easy to think critically, as it can take a pretty smart person to see some of the questions that aren't being answered in a certain situation. But, we can train our brains to think more like puzzle solvers, which can help develop our critical thinking skills.

Here's what it looks like step by step:

Spotting the Problem: It's like discovering a puzzle to solve. You see that there's something you need to figure out or decide.

Collecting Clues: Now, you need to gather information. Maybe you read about it, watch a video, talk to people, or do some research. It's like getting all the pieces to solve your puzzle.

Breaking It Down: This is where you look at all your clues and try to see how they fit together. You're asking questions like: Why did this happen? What could happen next?

Checking Your Clues: You want to make sure your information is good. This means seeing if what you found out is true and if you can trust where it came from.

Making a Guess: After looking at all your clues, you think about what they mean and come up with an answer. This answer is like your best guess based on what you know.

Explaining Your Thoughts: Now, you tell others how you solved the puzzle. You explain how you thought about it and how you answered. 

Checking Your Work: This is like looking back and seeing if you missed anything. Did you make any mistakes? Did you let any personal feelings get in the way? This step helps make sure your thinking is clear and fair.

And remember, you might sometimes need to go back and redo some steps if you discover something new. If you realize you missed an important clue, you might have to go back and collect more information.

Critical Thinking Methods

Just like doing push-ups or running helps our bodies get stronger, there are special exercises that help our brains think better. These brain workouts push us to think harder, look at things closely, and ask many questions.

It's not always about finding the "right" answer. Instead, it's about the journey of thinking and asking "why" or "how." Doing these exercises often helps us become better thinkers and makes us curious to know more about the world.

Now, let's look at some brain workouts to help us think better:

1. "What If" Scenarios

Imagine crazy things happening, like, "What if there was no internet for a month? What would we do?" These games help us think of new and different ideas.

Pick a hot topic. Argue one side of it and then try arguing the opposite. This makes us see different viewpoints and think deeply about a topic.

3. Analyze Visual Data

Check out charts or pictures with lots of numbers and info but no explanations. What story are they telling? This helps us get better at understanding information just by looking at it.

4. Mind Mapping

Write an idea in the center and then draw lines to related ideas. It's like making a map of your thoughts. This helps us see how everything is connected.

There's lots of mind-mapping software , but it's also nice to do this by hand.

5. Weekly Diary

Every week, write about what happened, the choices you made, and what you learned. Writing helps us think about our actions and how we can do better.

6. Evaluating Information Sources

Collect stories or articles about one topic from newspapers or blogs. Which ones are trustworthy? Which ones might be a little biased? This teaches us to be smart about where we get our info.

There are many resources to help you determine if information sources are factual or not.

7. Socratic Questioning

This way of thinking is called the Socrates Method, named after an old-time thinker from Greece. It's about asking lots of questions to understand a topic. You can do this by yourself or chat with a friend.

Start with a Big Question:

"What does 'success' mean?"

Dive Deeper with More Questions:

"Why do you think of success that way?" "Do TV shows, friends, or family make you think that?" "Does everyone think about success the same way?"

"Can someone be a winner even if they aren't rich or famous?" "Can someone feel like they didn't succeed, even if everyone else thinks they did?"

Look for Real-life Examples:

"Who is someone you think is successful? Why?" "Was there a time you felt like a winner? What happened?"

Think About Other People's Views:

"How might a person from another country think about success?" "Does the idea of success change as we grow up or as our life changes?"

Think About What It Means:

"How does your idea of success shape what you want in life?" "Are there problems with only wanting to be rich or famous?"

Look Back and Think:

"After talking about this, did your idea of success change? How?" "Did you learn something new about what success means?"

8. Six Thinking Hats 

Edward de Bono came up with a cool way to solve problems by thinking in six different ways, like wearing different colored hats. You can do this independently, but it might be more effective in a group so everyone can have a different hat color. Each color has its way of thinking:

White Hat (Facts): Just the facts! Ask, "What do we know? What do we need to find out?"

Red Hat (Feelings): Talk about feelings. Ask, "How do I feel about this?"

Black Hat (Careful Thinking): Be cautious. Ask, "What could go wrong?"

Yellow Hat (Positive Thinking): Look on the bright side. Ask, "What's good about this?"

Green Hat (Creative Thinking): Think of new ideas. Ask, "What's another way to look at this?"

Blue Hat (Planning): Organize the talk. Ask, "What should we do next?"

When using this method with a group:

• Explain all the hats.
• Decide which hat to wear first.
• Make sure everyone switches hats at the same time.
• Finish with the Blue Hat to plan the next steps.

9. SWOT Analysis

SWOT Analysis is like a game plan for businesses to know where they stand and where they should go. "SWOT" stands for Strengths, Weaknesses, Opportunities, and Threats.

There are a lot of SWOT templates out there for how to do this visually, but you can also think it through. It doesn't just apply to businesses but can be a good way to decide if a project you're working on is working.

Strengths: What's working well? Ask, "What are we good at?"

Weaknesses: Where can we do better? Ask, "Where can we improve?"

Opportunities: What good things might come our way? Ask, "What chances can we grab?"

Threats: What challenges might we face? Ask, "What might make things tough for us?"

Steps to do a SWOT Analysis:

• Goal: Decide what you want to find out.
• Research: Learn about your business and the world around it.
• Brainstorm: Get a group and think together. Talk about strengths, weaknesses, opportunities, and threats.
• Pick the Most Important Points: Some things might be more urgent or important than others.
• Make a Plan: Decide what to do based on your SWOT list.
• Check Again Later: Things change, so look at your SWOT again after a while to update it.

Now that you have a few tools for thinking critically, let’s get into some specific examples.

Everyday Examples

Life is a series of decisions. From the moment we wake up, we're faced with choices – some trivial, like choosing a breakfast cereal, and some more significant, like buying a home or confronting an ethical dilemma at work. While it might seem that these decisions are disparate, they all benefit from the application of critical thinking.

10. Deciding to buy something

Imagine you want a new phone. Don't just buy it because the ad looks cool. Think about what you need in a phone. Look up different phones and see what people say about them. Choose the one that's the best deal for what you want.

11. Deciding what is true

There's a lot of news everywhere. Don't believe everything right away. Think about why someone might be telling you this. Check if what you're reading or watching is true. Make up your mind after you've looked into it.

12. Deciding when you’re wrong

Sometimes, friends can have disagreements. Don't just get mad right away. Try to see where they're coming from. Talk about what's going on. Find a way to fix the problem that's fair for everyone.

13. Deciding what to eat

There's always a new diet or exercise that's popular. Don't just follow it because it's trendy. Find out if it's good for you. Ask someone who knows, like a doctor. Make choices that make you feel good and stay healthy.

14. Deciding what to do today

Everyone is busy with school, chores, and hobbies. Make a list of things you need to do. Decide which ones are most important. Plan your day so you can get things done and still have fun.

15. Making Tough Choices

Sometimes, it's hard to know what's right. Think about how each choice will affect you and others. Talk to people you trust about it. Choose what feels right in your heart and is fair to others.

16. Planning for the Future

Big decisions, like where to go to school, can be tricky. Think about what you want in the future. Look at the good and bad of each choice. Talk to people who know about it. Pick what feels best for your dreams and goals.

Job Examples

17. solving problems.

Workers brainstorm ways to fix a machine quickly without making things worse when a machine breaks at a factory.

23. Asking Questions

Before starting a big task, an employee asks for clear instructions and checks if they have the necessary tools.

24. Checking Facts

Before presenting a report, someone double-checks all their information to make sure there are no mistakes.

25. Planning for the Future

School Examples

27. researching a topic.

For a history project, a student looks up different sources to understand an event from multiple viewpoints.

28. Debating an Issue

In a class discussion, students pick sides on a topic, like school uniforms, and share reasons to support their views.

29. Evaluating Sources

While writing an essay, a student checks if the information from a website is trustworthy or might be biased.

30. Problem Solving in Math

When stuck on a tricky math problem, a student tries different methods to find the answer instead of giving up.

31. Analyzing Literature

In English class, students discuss why a character in a book made certain choices and what those decisions reveal about them.

32. Testing a Hypothesis

For a science experiment, students guess what will happen and then conduct tests to see if they're right or wrong.

33. Giving Peer Feedback

After reading a classmate's essay, a student offers suggestions for improving it.

34. Questioning Assumptions

In a geography lesson, students consider why certain countries are called "developed" and what that label means.

35. Designing a Study

36. Interpreting Data

In a science class, students look at charts and graphs from a study, then discuss what the information tells them and if there are any patterns.

Critical Thinking Puzzles

Not all scenarios will have a single correct answer that can be figured out by thinking critically. Sometimes we have to think critically about ethical choices or moral behaviors. 

Here are some mind games and scenarios you can solve using critical thinking. You can see the solution(s) at the end of the post.

37. The Farmer, Fox, Chicken, and Grain Problem

A farmer is at a riverbank with a fox, a chicken, and a grain bag. He needs to get all three items across the river. However, his boat can only carry himself and one of the three items at a time. 

Here's the challenge:

• If the fox is left alone with the chicken, the fox will eat the chicken.
• If the chicken is left alone with the grain, the chicken will eat the grain.

How can the farmer get all three items across the river without any item being eaten? 

38. The Rope, Jar, and Pebbles Problem

You are in a room with two long ropes hanging from the ceiling. Each rope is just out of arm's reach from the other, so you can't hold onto one rope and reach the other simultaneously. 

Your task is to tie the two rope ends together, but you can't move the position where they hang from the ceiling.

You are given a jar full of pebbles. How do you complete the task?

39. The Two Guards Problem

Imagine there are two doors. One door leads to certain doom, and the other leads to freedom. You don't know which is which.

In front of each door stands a guard. One guard always tells the truth. The other guard always lies. You don't know which guard is which.

You can ask only one question to one of the guards. What question should you ask to find the door that leads to freedom?

40. The Hourglass Problem

You have two hourglasses. One measures 7 minutes when turned over, and the other measures 4 minutes. Using just these hourglasses, how can you time exactly 9 minutes?

41. The Lifeboat Dilemma

Imagine you're on a ship that's sinking. You get on a lifeboat, but it's already too full and might flip over. 

Nearby in the water, five people are struggling: a scientist close to finding a cure for a sickness, an old couple who've been together for a long time, a mom with three kids waiting at home, and a tired teenager who helped save others but is now in danger. 

You can only save one person without making the boat flip. Who would you choose?

42. The Tech Dilemma

You work at a tech company and help make a computer program to help small businesses. You're almost ready to share it with everyone, but you find out there might be a small chance it has a problem that could show users' private info. 

If you decide to fix it, you must wait two more months before sharing it. But your bosses want you to share it now. What would you do?

43. The History Mystery

Dr. Amelia is a history expert. She's studying where a group of people traveled long ago. She reads old letters and documents to learn about it. But she finds some letters that tell a different story than what most people believe. 

If she says this new story is true, it could change what people learn in school and what they think about history. What should she do?

The Role of Bias in Critical Thinking

Have you ever decided you don’t like someone before you even know them? Or maybe someone shared an idea with you that you immediately loved without even knowing all the details. 

This experience is called bias, which occurs when you like or dislike something or someone without a good reason or knowing why. It can also take shape in certain reactions to situations, like a habit or instinct. 

Bias comes from our own experiences, what friends or family tell us, or even things we are born believing. Sometimes, bias can help us stay safe, but other times it stops us from seeing the truth.

Not all bias is bad. Bias can be a mechanism for assessing our potential safety in a new situation. If we are biased to think that anything long, thin, and curled up is a snake, we might assume the rope is something to be afraid of before we know it is just a rope.

While bias might serve us in some situations (like jumping out of the way of an actual snake before we have time to process that we need to be jumping out of the way), it often harms our ability to think critically.

How Bias Gets in the Way of Good Thinking

Selective Perception: We only notice things that match our ideas and ignore the rest. 

It's like only picking red candies from a mixed bowl because you think they taste the best, but they taste the same as every other candy in the bowl. It could also be when we see all the signs that our partner is cheating on us but choose to ignore them because we are happy the way we are (or at least, we think we are).

Agreeing with Yourself: This is called “ confirmation bias ” when we only listen to ideas that match our own and seek, interpret, and remember information in a way that confirms what we already think we know or believe. 

An example is when someone wants to know if it is safe to vaccinate their children but already believes that vaccines are not safe, so they only look for information supporting the idea that vaccines are bad.

Thinking We Know It All: Similar to confirmation bias, this is called “overconfidence bias.” Sometimes we think our ideas are the best and don't listen to others. This can stop us from learning.

Have you ever met someone who you consider a “know it”? Probably, they have a lot of overconfidence bias because while they may know many things accurately, they can’t know everything. Still, if they act like they do, they show overconfidence bias.

There's a weird kind of bias similar to this called the Dunning Kruger Effect, and that is when someone is bad at what they do, but they believe and act like they are the best .

Following the Crowd: This is formally called “groupthink”. It's hard to speak up with a different idea if everyone agrees. But this can lead to mistakes.

An example of this we’ve all likely seen is the cool clique in primary school. There is usually one person that is the head of the group, the “coolest kid in school”, and everyone listens to them and does what they want, even if they don’t think it’s a good idea.

How to Overcome Biases

Here are a few ways to learn to think better, free from our biases (or at least aware of them!).

Know Your Biases: Realize that everyone has biases. If we know about them, we can think better.

Listen to Different People: Talking to different kinds of people can give us new ideas.

Ask Why: Always ask yourself why you believe something. Is it true, or is it just a bias?

Understand Others: Try to think about how others feel. It helps you see things in new ways.

Keep Learning: Always be curious and open to new information.

In today's world, everything changes fast, and there's so much information everywhere. This makes critical thinking super important. It helps us distinguish between what's real and what's made up. It also helps us make good choices. But thinking this way can be tough sometimes because of biases. These are like sneaky thoughts that can trick us. The good news is we can learn to see them and think better.

There are cool tools and ways we've talked about, like the "Socratic Questioning" method and the "Six Thinking Hats." These tools help us get better at thinking. These thinking skills can also help us in school, work, and everyday life.

We’ve also looked at specific scenarios where critical thinking would be helpful, such as deciding what diet to follow and checking facts.

Thinking isn't just a skill—it's a special talent we improve over time. Working on it lets us see things more clearly and understand the world better. So, keep practicing and asking questions! It'll make you a smarter thinker and help you see the world differently.

Critical Thinking Puzzles (Solutions)

The farmer, fox, chicken, and grain problem.

• The farmer first takes the chicken across the river and leaves it on the other side.
• He returns to the original side and takes the fox across the river.
• After leaving the fox on the other side, he returns the chicken to the starting side.
• He leaves the chicken on the starting side and takes the grain bag across the river.
• He leaves the grain with the fox on the other side and returns to get the chicken.
• The farmer takes the chicken across, and now all three items -- the fox, the chicken, and the grain -- are safely on the other side of the river.

The Rope, Jar, and Pebbles Problem

• Take one rope and tie the jar of pebbles to its end.
• Swing the rope with the jar in a pendulum motion.
• While the rope is swinging, grab the other rope and wait.
• As the swinging rope comes back within reach due to its pendulum motion, grab it.
• With both ropes within reach, untie the jar and tie the rope ends together.

The Two Guards Problem

The question is, "What would the other guard say is the door to doom?" Then choose the opposite door.

The Hourglass Problem

• Start both hourglasses. 
• When the 4-minute hourglass runs out, turn it over.
• When the 7-minute hourglass runs out, the 4-minute hourglass will have been running for 3 minutes. Turn the 7-minute hourglass over. 
• When the 4-minute hourglass runs out for the second time (a total of 8 minutes have passed), the 7-minute hourglass will run for 1 minute. Turn the 7-minute hourglass again for 1 minute to empty the hourglass (a total of 9 minutes passed).

The Boat and Weights Problem

Take the cat over first and leave it on the other side. Then, return and take the fish across next. When you get there, take the cat back with you. Leave the cat on the starting side and take the cat food across. Lastly, return to get the cat and bring it to the other side.

The Lifeboat Dilemma

There isn’t one correct answer to this problem. Here are some elements to consider:

• Moral Principles: What values guide your decision? Is it the potential greater good for humanity (the scientist)? What is the value of long-standing love and commitment (the elderly couple)? What is the future of young children who depend on their mothers? Or the selfless bravery of the teenager?
• Future Implications: Consider the future consequences of each choice. Saving the scientist might benefit millions in the future, but what moral message does it send about the value of individual lives?
• Emotional vs. Logical Thinking: While it's essential to engage empathy, it's also crucial not to let emotions cloud judgment entirely. For instance, while the teenager's bravery is commendable, does it make him more deserving of a spot on the boat than the others?
• Acknowledging Uncertainty: The scientist claims to be close to a significant breakthrough, but there's no certainty. How does this uncertainty factor into your decision?
• Personal Bias: Recognize and challenge any personal biases, such as biases towards age, profession, or familial status.

The Tech Dilemma

Again, there isn’t one correct answer to this problem. Here are some elements to consider:

• Evaluate the Risk: How severe is the potential vulnerability? Can it be easily exploited, or would it require significant expertise? Even if the circumstances are rare, what would be the consequences if the vulnerability were exploited?
• Stakeholder Considerations: Different stakeholders will have different priorities. Upper management might prioritize financial projections, the marketing team might be concerned about the product's reputation, and customers might prioritize the security of their data. How do you balance these competing interests?
• Short-Term vs. Long-Term Implications: While launching on time could meet immediate financial goals, consider the potential long-term damage to the company's reputation if the vulnerability is exploited. Would the short-term gains be worth the potential long-term costs?
• Ethical Implications : Beyond the financial and reputational aspects, there's an ethical dimension to consider. Is it right to release a product with a known vulnerability, even if the chances of it being exploited are low?
• Seek External Input: Consulting with cybersecurity experts outside your company might be beneficial. They could provide a more objective risk assessment and potential mitigation strategies.
• Communication: How will you communicate the decision, whatever it may be, both internally to your team and upper management and externally to your customers and potential users?

The History Mystery

Dr. Amelia should take the following steps:

• Verify the Letters: Before making any claims, she should check if the letters are actual and not fake. She can do this by seeing when and where they were written and if they match with other things from that time.
• Get a Second Opinion: It's always good to have someone else look at what you've found. Dr. Amelia could show the letters to other history experts and see their thoughts.
• Research More: Maybe there are more documents or letters out there that support this new story. Dr. Amelia should keep looking to see if she can find more evidence.
• Share the Findings: If Dr. Amelia believes the letters are true after all her checks, she should tell others. This can be through books, talks, or articles.
• Stay Open to Feedback: Some people might agree with Dr. Amelia, and others might not. She should listen to everyone and be ready to learn more or change her mind if new information arises.

Ultimately, Dr. Amelia's job is to find out the truth about history and share it. It's okay if this new truth differs from what people used to believe. History is about learning from the past, no matter the story.

Why Is Critical Thinking Important? A Survival Guide

Updated: December 7, 2023

Published: April 2, 2020

Why is critical thinking important? The decisions that you make affect your quality of life. And if you want to ensure that you live your best, most successful and happy life, you’re going to want to make conscious choices. That can be done with a simple thing known as critical thinking. Here’s how to improve your critical thinking skills and make decisions that you won’t regret.

What Is Critical Thinking?

You’ve surely heard of critical thinking, but you might not be entirely sure what it really means, and that’s because there are many definitions. For the most part, however, we think of critical thinking as the process of analyzing facts in order to form a judgment. Basically, it’s thinking about thinking.

How Has The Definition Evolved Over Time?

The first time critical thinking was documented is believed to be in the teachings of Socrates , recorded by Plato. But throughout history, the definition has changed.

Today it is best understood by philosophers and psychologists and it’s believed to be a highly complex concept. Some insightful modern-day critical thinking definitions include :

• “Reasonable, reflective thinking that is focused on deciding what to believe or do.”
• “Deciding what’s true and what you should do.”

The Importance Of Critical Thinking

Why is critical thinking important? Good question! Here are a few undeniable reasons why it’s crucial to have these skills.

1. Critical Thinking Is Universal

Critical thinking is a domain-general thinking skill. What does this mean? It means that no matter what path or profession you pursue, these skills will always be relevant and will always be beneficial to your success. They are not specific to any field.

2. Crucial For The Economy

Our future depends on technology, information, and innovation. Critical thinking is needed for our fast-growing economies, to solve problems as quickly and as effectively as possible.

3. Improves Language & Presentation Skills

In order to best express ourselves, we need to know how to think clearly and systematically — meaning practice critical thinking! Critical thinking also means knowing how to break down texts, and in turn, improve our ability to comprehend.

4. Promotes Creativity

By practicing critical thinking, we are allowing ourselves not only to solve problems but also to come up with new and creative ideas to do so. Critical thinking allows us to analyze these ideas and adjust them accordingly.

5. Important For Self-Reflection

Without critical thinking, how can we really live a meaningful life? We need this skill to self-reflect and justify our ways of life and opinions. Critical thinking provides us with the tools to evaluate ourselves in the way that we need to.

6. The Basis Of Science & Democracy

In order to have a democracy and to prove scientific facts, we need critical thinking in the world. Theories must be backed up with knowledge. In order for a society to effectively function, its citizens need to establish opinions about what’s right and wrong (by using critical thinking!).

Benefits Of Critical Thinking

We know that critical thinking is good for society as a whole, but what are some benefits of critical thinking on an individual level? Why is critical thinking important for us?

1. Key For Career Success

Critical thinking is crucial for many career paths. Not just for scientists, but lawyers , doctors, reporters, engineers , accountants, and analysts (among many others) all have to use critical thinking in their positions. In fact, according to the World Economic Forum, critical thinking is one of the most desirable skills to have in the workforce, as it helps analyze information, think outside the box, solve problems with innovative solutions, and plan systematically.

2. Better Decision Making

There’s no doubt about it — critical thinkers make the best choices. Critical thinking helps us deal with everyday problems as they come our way, and very often this thought process is even done subconsciously. It helps us think independently and trust our gut feeling.

3. Can Make You Happier!

While this often goes unnoticed, being in touch with yourself and having a deep understanding of why you think the way you think can really make you happier. Critical thinking can help you better understand yourself, and in turn, help you avoid any kind of negative or limiting beliefs, and focus more on your strengths. Being able to share your thoughts can increase your quality of life.

4. Form Well-Informed Opinions

There is no shortage of information coming at us from all angles. And that’s exactly why we need to use our critical thinking skills and decide for ourselves what to believe. Critical thinking allows us to ensure that our opinions are based on the facts, and help us sort through all that extra noise.

5. Better Citizens

One of the most inspiring critical thinking quotes is by former US president Thomas Jefferson: “An educated citizenry is a vital requisite for our survival as a free people.” What Jefferson is stressing to us here is that critical thinkers make better citizens, as they are able to see the entire picture without getting sucked into biases and propaganda.

6. Improves Relationships

While you may be convinced that being a critical thinker is bound to cause you problems in relationships, this really couldn’t be less true! Being a critical thinker can allow you to better understand the perspective of others, and can help you become more open-minded towards different views.

7. Promotes Curiosity

Critical thinkers are constantly curious about all kinds of things in life, and tend to have a wide range of interests. Critical thinking means constantly asking questions and wanting to know more, about why, what, who, where, when, and everything else that can help them make sense of a situation or concept, never taking anything at face value.

8. Allows For Creativity

Critical thinkers are also highly creative thinkers, and see themselves as limitless when it comes to possibilities. They are constantly looking to take things further, which is crucial in the workforce.

9. Enhances Problem Solving Skills

Those with critical thinking skills tend to solve problems as part of their natural instinct. Critical thinkers are patient and committed to solving the problem, similar to Albert Einstein, one of the best critical thinking examples, who said “It’s not that I’m so smart; it’s just that I stay with problems longer.” Critical thinkers’ enhanced problem-solving skills makes them better at their jobs and better at solving the world’s biggest problems. Like Einstein, they have the potential to literally change the world.

10. An Activity For The Mind

Just like our muscles, in order for them to be strong, our mind also needs to be exercised and challenged. It’s safe to say that critical thinking is almost like an activity for the mind — and it needs to be practiced. Critical thinking encourages the development of many crucial skills such as logical thinking, decision making, and open-mindness.

11. Creates Independence

When we think critically, we think on our own as we trust ourselves more. Critical thinking is key to creating independence, and encouraging students to make their own decisions and form their own opinions.

12. Crucial Life Skill

Critical thinking is crucial not just for learning, but for life overall! Education isn’t just a way to prepare ourselves for life, but it’s pretty much life itself. Learning is a lifelong process that we go through each and every day.

How to Think Critically

Now that you know the benefits of thinking critically, how do you actually do it?

How To Improve Your Critical Thinking

• Define Your Question: When it comes to critical thinking, it’s important to always keep your goal in mind. Know what you’re trying to achieve, and then figure out how to best get there.
• Gather Reliable Information: Make sure that you’re using sources you can trust — biases aside. That’s how a real critical thinker operates!
• Ask The Right Questions: We all know the importance of questions, but be sure that you’re asking the right questions that are going to get you to your answer.
• Look Short & Long Term: When coming up with solutions, think about both the short- and long-term consequences. Both of them are significant in the equation.
• Explore All Sides: There is never just one simple answer, and nothing is black or white. Explore all options and think outside of the box before you come to any conclusions.

How Is Critical Thinking Developed At School?

Critical thinking is developed in nearly everything we do. However, much of this important skill is encouraged to be practiced at school, and rightfully so! Critical thinking goes beyond just thinking clearly — it’s also about thinking for yourself.

When a teacher asks a question in class, students are given the chance to answer for themselves and think critically about what they learned and what they believe to be accurate. When students work in groups and are forced to engage in discussion, this is also a great chance to expand their thinking and use their critical thinking skills.

How Does Critical Thinking Apply To Your Career?

Once you’ve finished school and entered the workforce, your critical thinking journey only expands and grows from here!

Impress Your Employer

Employers value employees who are critical thinkers, ask questions, offer creative ideas, and are always ready to offer innovation against the competition. No matter what your position or role in a company may be, critical thinking will always give you the power to stand out and make a difference.

Careers That Require Critical Thinking

Some of many examples of careers that require critical thinking include:

• Human resources specialist
• Marketing associate
• Business analyst

Truth be told however, it’s probably harder to come up with a professional field that doesn’t require any critical thinking!

What is someone with critical thinking skills capable of doing.

Someone with critical thinking skills is able to think rationally and clearly about what they should or not believe. They are capable of engaging in their own thoughts, and doing some reflection in order to come to a well-informed conclusion.

A critical thinker understands the connections between ideas, and is able to construct arguments based on facts, as well as find mistakes in reasoning.

The Process Of Critical Thinking

The process of critical thinking is highly systematic.

What Are Your Goals?

Critical thinking starts by defining your goals, and knowing what you are ultimately trying to achieve.

Once you know what you are trying to conclude, you can foresee your solution to the problem and play it out in your head from all perspectives.

What Does The Future Of Critical Thinking Hold?

The future of critical thinking is the equivalent of the future of jobs. In 2020, critical thinking was ranked as the 2nd top skill (following complex problem solving) by the World Economic Forum .

We are dealing with constant unprecedented changes, and what success is today, might not be considered success tomorrow — making critical thinking a key skill for the future workforce.

Why Is Critical Thinking So Important?

Why is critical thinking important? Critical thinking is more than just important! It’s one of the most crucial cognitive skills one can develop.

By practicing well-thought-out thinking, both your thoughts and decisions can make a positive change in your life, on both a professional and personal level. You can hugely improve your life by working on your critical thinking skills as often as you can.

In this article, we will explain 9 strategies that any motivated person can use to develop as a thinker. As we explain the strategy, we will describe it as if we were talking directly to such a person. Further details to our descriptions may need to be added for those who know little about critical thinking. Here are the 9:

There is nothing magical about our ideas. No one of them is essential. Nevertheless, each represents a plausible way to begin to do something concrete to improve thinking in a regular way. Though you probably can’t do all of these at the same time, we recommend an approach in which you experiment with all of these over an extended period of time.

First Strategy: Use “Wasted” Time. All humans waste some time; that is, fail to use all of their time productively or even pleasurably. Sometimes we jump from one diversion to another, without enjoying any of them. Sometimes we become irritated about matters beyond our control. Sometimes we fail to plan well causing us negative consequences we could easily have avoided (for example, we spend time unnecessarily trapped in traffic — though we could have left a half hour earlier and avoided the rush). Sometimes we worry unproductively. Sometimes we spend time regretting what is past. Sometimes we just stare off blankly into space.

The key is that the time is “gone” even though, if we had thought about it and considered our options, we would never have deliberately spent our time in the way we did. So why not take advantage of the time you normally waste by practicing your critical thinking during that otherwise wasted time? For example, instead of sitting in front of the TV at the end of the day flicking from channel to channel in a vain search for a program worth watching, spend that time, or at least part of it, thinking back over your day and evaluating your strengths and weaknesses. For example, you might ask yourself questions like these:

When did I do my worst thinking today? When did I do my best? What in fact did I think about today? Did I figure anything out? Did I allow any negative thinking to frustrate me unnecessarily? If I had to repeat today what would I do differently? Why? Did I do anything today to further my long-term goals? Did I act in accordance with my own expressed values? If I spent every day this way for 10 years, would I at the end have accomplished something worthy of that time?

It would be important of course to take a little time with each question. It would also be useful to record your observations so that you are forced to spell out details and be explicit in what you recognize and see. As time passes, you will notice patterns in your thinking. Second Strategy: A Problem A Day. At the beginning of each day (perhaps driving to work or going to school) choose a problem to work on when you have free moments. Figure out the logic of the problem by identifying its elements. In other words, systematically think through the questions: What exactly is the problem? How can I put it into the form of a question. How does it relate to my goals, purposes, and needs?

Third Strategy: Internalize Intellectual Standards. Each week, develop a heightened awareness of one of the universal intellectual standards (clarity, precision, accuracy, relevance, depth, breadth, logicalness, significance). Focus one week on clarity, the next on accuracy, etc. For example, if you are focusing on clarity for the week, try to notice when you are being unclear in communicating with others. Notice when others are unclear in what they are saying.

When you are reading, notice whether you are clear about what you are reading. When you orally express or write out your views (for whatever reason), ask yourself whether you are clear about what you are trying to say. In doing this, of course, focus on four techniques of clarification : 1) Stating what you are saying explicitly and precisely (with careful consideration given to your choice of words), 2) Elaborating on your meaning in other words, 3) Giving examples of what you mean from experiences you have had, and 4) Using analogies , metaphors, pictures, or diagrams to illustrate what you mean. In other words, you will frequently STATE, ELABORATE, ILLUSTRATE, AND EXEMPLIFY your points. You will regularly ask others to do the same.

Fourth Strategy: Keep An Intellectual Journal. Each week, write out a certain number of journal entries. Use the following format (keeping each numbered stage separate):

Strategy Five: Reshape Your Character. Choose one intellectual trait---intellectual perseverance, autonomy, empathy, courage, humility, etc.--- to strive for each month, focusing on how you can develop that trait in yourself. For example, concentrating on intellectual humility, begin to notice when you admit you are wrong. Notice when you refuse to admit you are wrong, even in the face of glaring evidence that you are in fact wrong. Notice when you become defensive when another person tries to point out a deficiency in your work, or your thinking. Notice when your intellectual arrogance keeps you from learning, for example, when you say to yourself “I already know everything I need to know about this subject.” Or, “I know as much as he does. Who does he think he is forcing his opinions on me?” By owning your “ignorance,” you can begin to deal with it.

Strategy Six: Deal with Your Egocentrism. Egocentric thinking is found in the disposition in human nature to think with an automatic subconscious bias in favor of oneself. On a daily basis, you can begin to observe your egocentric thinking in action by contemplating questions like these: Under what circumstances do I think with a bias in favor of myself? Did I ever become irritable over small things? Did I do or say anything “irrational” to get my way? Did I try to impose my will upon others? Did I ever fail to speak my mind when I felt strongly about something, and then later feel resentment? Once you identify egocentric thinking in operation, you can then work to replace it with more rational thought through systematic self-reflection, thinking along the lines of: What would a rational person feel in this or that situation? What would a rational person do? How does that compare with what I want to do? (Hint: If you find that you continually conclude that a rational person would behave just as you behaved you are probably engaging in self-deception.)

Strategy Seven: Redefine the Way You See Things . We live in a world, both personal and social, in which every situation is “defined,” that is, given a meaning. How a situation is defined determines not only how we feel about it, but also how we act in it, and what implications it has for us. However, virtually every situation can be defined in more than one way. This fact carries with it tremendous opportunities. In principle, it lies within your power and mine to make our lives more happy and fulfilling than they are. Many of the negative definitions that we give to situations in our lives could in principle be transformed into positive ones. We can be happy when otherwise we would have been sad.

We can be fulfilled when otherwise we would have been frustrated. In this strategy, we practice redefining the way we see things, turning negatives into positives, dead-ends into new beginnings, mistakes into opportunities to learn. To make this strategy practical, we should create some specific guidelines for ourselves. For example, we might make ourselves a list of five to ten recurrent negative contexts in which we feel frustrated, angry, unhappy, or worried. We could then identify the definition in each case that is at the root of the negative emotion. We would then choose a plausible alternative definition for each and then plan for our new responses as well as new emotions. For example, if you tend to worry about all problems, both the ones you can do something about and those that you can’t; you can review the thinking in this nursery rhyme: “For every problem under the sun, there is a solution or there is none. If there be one, think til you find it. If there be none, then never mind it.”

Let’s look at another example. You do not have to define your initial approach to a member of the opposite sex in terms of the definition “his/her response will determine whether or not I am an attractive person.” Alternatively, you could define it in terms of the definition “let me test to see if this person is initially drawn to me—given the way they perceive me.” With the first definition in mind, you feel personally put down if the person is not “interested” in you; with the second definition you explicitly recognize that people respond not to the way a stranger is, but the way they look to them subjectively. You therefore do not take a failure to show interest in you (on the part of another) as a “defect” in you.

Strategy Eight: Get in touch with your emotions: Whenever you feel some negative emotion, systematically ask yourself: What, exactly, is the thinking leading to this emotion? For example, if you are angry, ask yourself, what is the thinking that is making me angry? What other ways could I think about this situation? For example, can you think about the situation so as to see the humor in it and what is pitiable in it? If you can, concentrate on that thinking and your emotions will (eventually) shift to match it.

Strategy Nine: Analyze group influences on your life: Closely analyze the behavior that is encouraged, and discouraged, in the groups to which you belong. For any given group, what are you "required" to believe? What are you "forbidden" to do? Every group enforces some level of conformity. Most people live much too much within the view of themselves projected by others. Discover what pressure you are bowing to and think explicitly about whether or not to reject that pressure.

Conclusion: The key point to keep in mind when devising strategies is that you are engaged in a personal experiment. You are testing ideas in your everyday life. You are integrating them, and building on them, in the light of your actual experience. For example, suppose you find the strategy “Redefine the Way You See Things” to be intuitive to you. So you use it to begin. Pretty soon you find yourself noticing the social definitions that rule many situations in your life. You recognize how your behavior is shaped and controlled by the definitions in use:

• “I’m giving a party,” (Everyone therefore knows to act in a “partying” way)
• “The funeral is Tuesday,” (There are specific social behaviors expected at a funeral)
• “Jack is an acquaintance, not really a friend.” (We behave very differently in the two cases)

You begin to see how important and pervasive social definitions are. You begin to redefine situations in ways that run contrary to some commonly accepted definitions. You notice then how redefining situations (and relationships) enables you to “Get in Touch With Your Emotions.” You recognize that the way you think (that is, define things) generates the emotions you experience. When you think you are threatened (i.e., define a situation as “threatening”), you feel fear. If you define a situation as a “failure,” you may feel depressed. On the other hand, if you define that same situation as a “lesson or opportunity to learn” you feel empowered to learn. When you recognize this control that you are capable of exercising, the two strategies begin to work together and reinforce each other.

Next consider how you could integrate strategy #9 (“Analyze group influences on your life”) into your practice. One of the main things that groups do is control us by controlling the definitions we are allowed to operate with. When a group defines some things as “cool” and some as “dumb, ” the members of the group try to appear “cool” and not appear “dumb.” When the boss of a business says, “That makes a lot of sense,” his subordinates know they are not to say, “No, it is ridiculous.” And they know this because defining someone as the “boss” gives him/her special privileges to define situations and relationships.

You now have three interwoven strategies: you “Redefine the Way You See Things,” “Get in touch with your emotions,” and “Analyze group influences on your life.” The three strategies are integrated into one. You can now experiment with any of the other strategies, looking for opportunities to integrate them into your thinking and your life. If you follow through on some plan analogous to what we have described, you are developing as a thinker. More precisely, you are becoming a “Practicing” Thinker. Your practice will bring advancement. And with advancement, skilled and insightful thinking may becomes more and more natural to you.

What is critical thinking (a definition).

• “purposeful, self-regulatory judgment which results in interpretation, analysis, evaluation, and inference, as well as explanation of the evidential, conceptual, methodological, criteriological, or conceptual considerations upon which that judgment is based” (Facione, 1990, p. 3).
• “skillful, responsible thinking that facilitates good judgment because it 1) relies upon criteria, 2) is self-correcting, and 3) is sensitive to context” (Lipman, 1988, p. 39);
• “seeing both sides of an issue, being open to new evidence that disconfirms your ideas, reasoning dispassionately, demanding that claims be backed by evidence, deducing and inferring conclusions from available facts, solving problems , and so forth” (Willingham, 2007, p. 8). ​​

Barriers to Critical Thinking

How to think critically.

• Can you confirm the “facts” presented with multiple other sources?
• What level of expertise does the person presenting the argument have with the subject matter?
• Are there other explanations that are simpler or more likely to be true?
• Does the argument logically follow from the premise?
• Is there quantifiable evidence in support of the argument?
• Could the argument be proven false?

Critical Thinking Examples

• You’re scrolling through Instagram and see an ad for a serum that is “guaranteed” to make you’re your eyelashes 10x longer and thicker. Before deciding to purchase the product, you first look up the serum ingredients to determine whether there are any studies that support the claim in the ad.
• The governor of your state says that a particular virus is not dangerous or readily transmissible. Recognizing that the governor does not have any background in biology or virology, you decide to compare this declaration with what experts in the field have to say to see if the governor’s opinion aligns with the current consensus among scientists.
• You and your roommate hear a strange noise in the house. Your roommate speculates that the source of the noise was a poltergeist. You offer alternative hypotheses and the two of you discuss the plausibility of each hypothesis to identify which hypothesis is most likely to be true.

Critical Thinking Skills

• Interpretation – understanding the significance of a wide variety of experiences
• Analysis – examining ideas to identify the reasons and claims of an argument
• Explanation – presenting your reasoned argument including the evidence supporting it
• Evaluation – Assessing the credibility of claims and the quality of arguments made
• Inference – Formulating alternative hypotheses and drawing logically valid conclusions
• Self-regulation – Monitoring yourself and updating your viewpoint in accordance with the evidence

Quotes on Critical Thinking

• “It is the mark of an educated mind to be able to entertain a thought without accepting it.” – Aristotle
• “Critical thinking requires us to use our imagination , seeing things from perspectives other than our own and envisioning the likely consequences of our position.” – Bell Hooks
• “The opinions that are held with passion are always those for which no good ground exists; indeed the passion is the measure of the holder’s lack of rational conviction.” – Bertrand Russell
• “Those who can make you believe absurdities can make you commit atrocities.” – Voltaire
• “Freethinkers are those who are willing to use their minds without prejudice and without fearing to understand things that clash with their own customs, privileges, or beliefs. This state of mind is not common, but it is essential for critical thinking.” – Leo Tolstoy
• “A great many people think they are thinking when they are merely rearranging their prejudices.” – William James
• “Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.” – Carl Sagan
• “It is morally as bad not to care whether a thing is true or not, so long as it makes you feel good, as it is not to care how you got your money as long as you have got it.” – Edmond Way Teale
• “… For what a man had rather were true he more readily believes. Therefore he rejects difficult things from impatience of research; sober things, because they narrow hope; the deeper things of nature, from superstition; the light of experience, from arrogance and pride, lest his mind should seem to be occupied with things mean and transitory; things not commonly believed, out of deference to the opinion of the vulgar. Numberless in short are the ways, and sometimes imperceptible, in which the affections colour and infect the understanding.” – Sir Francis Bacon ​

Critical thinking.

Critical Thinking is the process of using and assessing reasons to evaluate statements, assumptions, and arguments in ordinary situations. The goal of this process is to help us have good beliefs, where “good” means that our beliefs meet certain goals of thought, such as truth, usefulness, or rationality. Critical thinking is widely regarded as a species of informal logic, although critical thinking makes use of some formal methods. In contrast with formal reasoning processes that are largely restricted to deductive methods—decision theory, logic, statistics—the process of critical thinking allows a wide range of reasoning methods, including formal and informal logic, linguistic analysis, experimental methods of the sciences, historical and textual methods, and philosophical methods, such as Socratic questioning and reasoning by counterexample.

The goals of critical thinking are also more diverse than those of formal reasoning systems. While formal methods focus on deductive validity and truth, critical thinkers may evaluate a statement’s truth, its usefulness, its religious value, its aesthetic value, or its rhetorical value. Because critical thinking arose primarily from the Anglo-American philosophical tradition (also known as “analytic philosophy”), contemporary critical thinking is largely concerned with a statement’s truth. But some thinkers, such as Aristotle (in Rhetoric ), give substantial attention to rhetorical value.

The primary subject matter of critical thinking is the proper use and goals of a range of reasoning methods, how they are applied in a variety of social contexts, and errors in reasoning. This article also discusses the scope and virtues of critical thinking.

Critical thinking should not be confused with Critical Theory. Critical Theory refers to a way of doing philosophy that involves a moral critique of culture. A “critical” theory, in this sense, is a theory that attempts to disprove or discredit a widely held or influential idea or way of thinking in society. Thus, critical race theorists and critical gender theorists offer critiques of traditional views and latent assumptions about race and gender. Critical theorists may use critical thinking methodology, but their subject matter is distinct, and they also may offer critical analyses of critical thinking itself.

The process of evaluating a statement traditionally begins with making sure we understand it; that is, a statement must express a clear meaning. A statement is generally regarded as clear if it expresses a proposition , which is the meaning the author of that statement intends to express, including definitions, referents of terms, and indexicals, such as subject, context, and time. There is significant controversy over what sort of “entity” propositions are, whether abstract objects or linguistic constructions or something else entirely. Whatever its metaphysical status, it is used here simply to refer to whatever meaning a speaker intends to convey in a statement.

The difficulty with identifying intended propositions is that we typically speak and think in natural languages (English, Swedish, French), and natural languages can be misleading. For instance, two different sentences in the same natural language may express the same proposition, as in these two English sentences:

Jamie is taller than his father. Jamie’s father is shorter than he.

Further, the same sentence in a natural language can express more than one proposition depending on who utters it at a time:

I am shorter than my father right now.

The pronoun “I” is an indexical; it picks out, or “indexes,” whoever utters the sentence and, therefore, expresses a different proposition for each new speaker who utters it. Similarly, “right now” is a temporal indexical; it indexes the time the sentence is uttered. The proposition it is used to express changes each new time the sentence is uttered and, therefore, may have a different truth value at different times (as, say, the speaker grows taller: “I am now five feet tall” may be true today, but false a year from now). Other indexical terms that can affect the meaning of the sentence include other pronouns (he, she, it) and definite articles (that, the).

Further still, different sentences in different natural languages may express the same proposition . For example, all of the following express the proposition “Snow is white”:

Snow is white. (English)

Der Schnee ist weiss. (German)

La neige est blanche. (French)

La neve é bianca. (Italian)

Finally, statements in natural languages are often vague or ambiguous , either of which can obscure the propositions actually intended by their authors. And even in cases where they are not vague or ambiguous, statements’ truth values sometimes vary from context to context. Consider the following example.

The English statement, “It is heavy,” includes the pronoun “it,” which (when used without contextual clues) is ambiguous because it can index any impersonal subject. If, in this case, “it” refers to the computer on which you are reading this right now, its author intends to express the proposition, “The computer on which you are reading this right now is heavy.” Further, the term “heavy” reflects an unspecified standard of heaviness (again, if contextual clues are absent). Assuming we are talking about the computer, it may be heavy relative to other computer models but not to automobiles. Further still, even if we identify or invoke a standard of heaviness by which to evaluate the appropriateness of its use in this context, there may be no weight at which an object is rightly regarded as heavy according to that standard. (For instance, is an object heavy because it weighs 5.3 pounds but not if it weighs 5.2 pounds? Or is it heavy when it is heavier than a mouse but lighter than an anvil?) This means “heavy” is a vague term. In order to construct a precise statement, vague terms (heavy, cold, tall) must often be replaced with terms expressing an objective standard (pounds, temperature, feet).

Part of the challenge of critical thinking is to clearly identify the propositions (meanings) intended by those making statements so we can effectively reason about them. The rules of language help us identify when a term or statement is ambiguous or vague, but they cannot, by themselves, help us resolve ambiguity or vagueness. In many cases, this requires assessing the context in which the statement is made or asking the author what she intends by the terms. If we cannot discern the meaning from the context and we cannot ask the author, we may stipulate a meaning, but this requires charity, to stipulate a plausible meaning, and humility, to admit when we discover that our stipulation is likely mistaken.

2. Argument and Evaluation

Once we are satisfied that a statement is clear, we can begin evaluating it. A statement can be evaluated according to a variety of standards. Commonly, statements are evaluated for truth, usefulness, or rationality. The most common of these goals is truth, so that is the focus of this article.

The truth of a statement is most commonly evaluated in terms of its relation to other statements and direct experiences. If a statement follows from or can be inferred from other statements that we already have good reasons to believe, then we have a reason to believe that statement. For instance, the statement “The ball is blue” can be derived from “The ball is blue and round.” Similarly, if a statement seems true in light of, or is implied by, an experience, then we have a reason to believe that statement. For instance, the experience of seeing a red car is a reason to believe, “The car is red.” (Whether these reasons are good enough for us to believe is a further question about justification , which is beyond the scope of this article, but see “ Epistemic Justification .”) Any statement we derive in these ways is called a conclusion . Though we regularly form conclusions from other statements and experiences—often without thinking about it—there is still a question of whether these conclusions are true: Did we draw those conclusions well? A common way to evaluate the truth of a statement is to identify those statements and experiences that support our conclusions and organize them into structures called arguments . (See also, “ Argument .”)

An argument is one or more statements (called premises ) intended to support the truth of another statement (the conclusion ). Premises comprise the evidence offered in favor of the truth of a conclusion. It is important to entertain any premises that are intended to support a conclusion, even if the attempt is unsuccessful. Unsuccessful attempts at supporting a proposition constitute bad arguments, but they are still arguments. The support intended for the conclusion may be formal or informal. In a formal, or deductive, argument, an arguer intends to construct an argument such that, if the premises are true, the conclusion must be true. This strong relationship between premises and conclusion is called validity . This relationship between the premises and conclusion is called “formal” because it is determined by the form (that is, the structure) of the argument (see §3). In an informal, or inductive , argument, the conclusion may be false even if the premises are true. In other words, whether an inductive argument is good depends on something more than the form of the argument. Therefore, all inductive arguments are invalid, but this does not mean they are bad arguments. Even if an argument is invalid, its premises can increase the probability that its conclusion is true. So, the form of inductive arguments is evaluated in terms of the strength the premises confer on the conclusion, and stronger inductive arguments are preferred to weaker ones (see §4). (See also, “ Deductive and Inductive Arguments .”)

Psychological states, such as sensations, memories, introspections, and intuitions often constitute evidence for statements. Although these states are not themselves statements, they can be expressed as statements. And when they are, they can be used in and evaluated by arguments. For instance, my seeing a red wall is evidence for me that, “There is a red wall,” but the physiological process of seeing is not a statement. Nevertheless, the experience of seeing a red wall can be expressed as the proposition, “I see a red wall” and can be included in an argument such as the following:

• I see a red wall in front of me.
• Therefore, there is a red wall in front of me.

This is an inductive argument, though not a strong one. We do not yet know whether seeing something (under these circumstances) is reliable evidence for the existence of what I am seeing. Perhaps I am “seeing” in a dream, in which case my seeing is not good evidence that there is a wall. For similar reasons, there is also reason to doubt whether I am actually seeing. To be cautious, we might say we seem to see a red wall.

To be good , an argument must meet two conditions: the conclusion must follow from the premises—either validly or with a high degree of likelihood—and the premises must be true. If the premises are true and the conclusion follows validly, the argument is sound . If the premises are true and the premises make the conclusion probable (either objectively or relative to alternative conclusions), the argument is cogent .

Here are two examples:

• Earth is larger than its moon.
• Our sun is larger than Earth.
• Therefore, our sun is larger than Earth’s moon.

In example 1, the premises are true. And since “larger than” is a transitive relation, the structure of the argument guarantees that, if the premises are true, the conclusion must be true. This means the argument is also valid. Since it is both valid and has true premises, this deductive argument is sound.

  Example 2:

• It is sunny in Montana about 205 days per year.
• I will be in Montana in February.
• Hence, it will probably be sunny when I am in Montana.

In example 2, premise 1 is true, and let us assume premise 2 is true. The phrase “almost always” indicates that a majority of days in Montana are sunny, so that, for any day you choose, it will probably be a sunny day. Premise 2 says I am choosing days in February to visit. Together, these premises strongly support (though they do not guarantee) the conclusion that it will be sunny when I am there, and so this inductive argument is cogent.

In some cases, arguments will be missing some important piece, whether a premise or a conclusion. For instance, imagine someone says, “Well, she asked you to go, so you have to go.” The idea that you have to go does not follow logically from the fact that she asked you to go without more information. What is it about her asking you to go that implies you have to go? Arguments missing important information are called enthymemes . A crucial part of critical thinking is identifying missing or assumed information in order to effectively evaluate an argument. In this example, the missing premise might be that, “She is your boss, and you have to do what she asks you to do.” Or it might be that, “She is the woman you are interested in dating, and if you want a real chance at dating her, you must do what she asks.” Before we can evaluate whether her asking implies that you have to go, we need to know this missing bit of information. And without that missing bit of information, we can simply reply, “That conclusion doesn’t follow from that premise.”

The two categories of reasoning associated with soundness and cogency—formal and informal, respectively—are considered, by some, to be the only two types of argument. Others add a third category, called abductive reasoning, according to which one reasons according to the rules of explanation rather than the rules of inference . Those who do not regard abductive reasoning as a third, distinct category typically regard it as a species of informal reasoning. Although abductive reasoning has unique features, here it is treated, for reasons explained in §4d, as a species of informal reasoning, but little hangs on this characterization for the purposes of this article.

3. Formal Reasoning

Although critical thinking is widely regarded as a type of informal reasoning, it nevertheless makes substantial use of formal reasoning strategies. Formal reasoning is deductive , which means an arguer intends to infer or derive a proposition from one or more propositions on the basis of the form or structure exhibited by the premises. Valid argument forms guarantee that particular propositions can be derived from them. Some forms look like they make such guarantees but fail to do so (we identify these as formal fallacies in §5a). If an arguer intends or supposes that a premise or set of premises guarantee a particular conclusion, we may evaluate that argument form as deductive even if the form fails to guarantee the conclusion, and is thus discovered to be invalid.

Before continuing in this section, it is important to note that, while formal reasoning provides a set of strict rules for drawing valid inferences, it cannot help us determine the truth of many of our original premises or our starting assumptions. And in fact, very little critical thinking that occurs in our daily lives (unless you are a philosopher, engineer, computer programmer, or statistician) involves formal reasoning. When we make decisions about whether to board an airplane, whether to move in with our significant others, whether to vote for a particular candidate, whether it is worth it to drive ten miles faster the speed limit even if I am fairly sure I will not get a ticket, whether it is worth it to cheat on a diet, or whether we should take a job overseas, we are reasoning informally. We are reasoning with imperfect information (I do not know much about my flight crew or the airplane’s history), with incomplete information (no one knows what the future is like), and with a number of built-in biases, some conscious (I really like my significant other right now), others unconscious (I have never gotten a ticket before, so I probably will not get one this time). Readers who are more interested in these informal contexts may want to skip to §4.

An argument form is a template that includes variables that can be replaced with sentences. Consider the following form (found within the formal system known as sentential logic ):

• If p, then q.
• Therefore, q.

This form was named modus ponens (Latin, “method of putting”) by medieval philosophers. p and q are variables that can be replaced with any proposition, however simple or complex. And as long as the variables are replaced consistently (that is, each instance of p is replaced with the same sentence and the same for q ), the conclusion (line 3), q , follows from these premises. To be more precise, the inference from the premises to the conclusion is valid . “Validity” describes a particular relationship between the premises and the conclusion, namely: in all cases , the conclusion follows necessarily from the premises, or, to use more technical language, the premises logically guarantee an instance of the conclusion.

Notice we have said nothing yet about truth . As critical thinkers, we are interested, primarily, in evaluating the truth of sentences that express propositions, but all we have discussed so far is a type of relationship between premises and conclusion (validity). This formal relationship is analogous to grammar in natural languages and is known in both fields as syntax . A sentence is grammatically correct if its syntax is appropriate for that language (in English, for example, a grammatically correct simple sentence has a subject and a predicate—“He runs.” “Laura is Chairperson.”—and it is grammatically correct regardless of what subject or predicate is used—“Jupiter sings.”—and regardless of whether the terms are meaningful—“Geflorble rowdies.”). Whether a sentence is meaningful, and therefore, whether it can be true or false, depends on its semantics , which refers to the meaning of individual terms (subjects and predicates) and the meaning that emerges from particular orderings of terms. Some terms are meaningless—geflorble; rowdies—and some orderings are meaningless even though their terms are meaningful—“Quadruplicity drinks procrastination,” and “Colorless green ideas sleep furiously.”.

Despite the ways that syntax and semantics come apart, if sentences are meaningful, then syntactic relationships between premises and conclusions allow reasoners to infer truth values for conclusions. Because of this, a more common definition of validity is this: it is not possible for all the premises to be true and the conclusion false . Formal logical systems in which syntax allows us to infer semantic values are called truth-functional or truth-preserving —proper syntax preserves truth throughout inferences.

The point of this is to note that formal reasoning only tells us what is true if we already know our premises are true. It cannot tell us whether our experiences are reliable or whether scientific experiments tell us what they seem to tell us. Logic can be used to help us determine whether a statement is true, but only if we already know some true things. This is why a broad conception of critical thinking is so important: we need many different tools to evaluate whether our beliefs are any good.

Consider, again, the form modus ponens , and replace p with “It is a cat” and q with “It is a mammal”:

• If it is a cat, then it is a mammal.
• It is a cat.
• Therefore, it is a mammal.

In this case, we seem to “see” (in a metaphorical sense of see ) that the premises guarantee the truth of the conclusion. On reflection, it is also clear that the premises might not be true; for instance, if “it” picks out a rock instead of a cat, premise 1 is still true, but premise 2 is false. It is also possible for the conclusion to be true when the premises are false. For instance, if the “it” picks out a dog instead of a cat, the conclusion “It is a mammal” is true. But in that case, the premises do not guarantee that conclusion; they do not constitute a reason to believe the conclusion is true.

Summing up, an argument is valid if its premises logically guarantee an instance of its conclusion (syntactically), or if it is not possible for its premises to be true and its conclusion false (semantically). Logic is truth-preserving but not truth-detecting; we still need evidence that our premises are true to use logic effectively.

            A Brief Technical Point

Some readers might find it worth noting that the semantic definition of validity has two counterintuitive consequences. First, it implies that any argument with a necessarily true conclusion is valid. Notice that the condition is phrased hypothetically: if the premises are true, then the conclusion cannot be false. This condition is met if the conclusion cannot be false:

• Two added to two equals four.

This is because the hypothetical (or “conditional”) statement would still be true even if the premises were false:

• If it is blue, then it flies.
• It is an airplane.

It is true of this argument that if the premises were true, the conclusion would be since the conclusion is true no matter what.

Second, the semantic formulation also implies that any argument with necessarily false premises is valid. The semantic condition for validity is met if the premises cannot be true:

• Some bachelors are married.
• Earth’s moon is heavier than Jupiter.

In this case, if the premise were true, the conclusion could not be false (this is because anything follows syntactically from a contradiction), and therefore, the argument is valid. There is nothing particularly problematic about these two consequences. But they highlight unexpected implications of our standard formulations of validity, and they show why there is more to good arguments than validity.

Despite these counterintuitive implications, valid reasoning is essential to thinking critically because it is a truth-preserving strategy: if deductive reasoning is applied to true premises, true conclusions will result.

There are a number of types of formal reasoning, but here we review only some of the most common: categorical logic, propositional logic, modal logic, and predicate logic.

a. Categorical Logic

Categorical logic is formal reasoning about categories or collections of subjects, where subjects refers to anything that can be regarded as a member of a class, whether objects, properties, or events or even a single object, property, or event. Categorical logic employs the quantifiers “all,” “some,” and “none” to refer to the members of categories, and categorical propositions are formulated in four ways:

A claims: All As are Bs (where the capitals “A” and “B” represent categories of subjects).

E claims: No As are Bs.

I claims: Some As are Bs.

O claims: Some As are not Bs.

Categorical syllogisms are syllogisms (two-premised formal arguments) that employ categorical propositions. Here are two examples:

• All cats are mammals. (A claim) 1. No bachelors are married. (E claim)
• Some cats are furry. (I claim) 2. All the people in this building are bachelors. (A claim)
• Therefore, some mammals are furry. (I claim) 3. Thus, no people in this building are married. (E claim)

There are interesting limitations on what categorical logic can do. For instance, if one premise says that, “Some As are not Bs,” may we infer that some As are Bs, in what is known as an “existential assumption”? Aristotle seemed to think so ( De Interpretatione ), but this cannot be decided within the rules of the system. Further, and counterintuitively, it would mean that a proposition such as, “Some bachelors are not married,” is false since it implies that some bachelors are married.

Another limitation on categorical logic is that arguments with more than three categories cannot be easily evaluated for validity. The standard method for evaluating the validity of categorical syllogisms is the Venn diagram (named after John Venn, who introduced it in 1881), which expresses categorical propositions in terms of two overlapping circles and categorical arguments in terms of three overlapping circles, each circle representing a category of subjects.

Venn diagram for claim and Venn diagram for argument

A, B, and C represent categories of objects, properties, or events. The symbol “ ∩ ” comes from mathematical set theory to indicate “intersects with.” “A∩B” means all those As that are also Bs and vice versa. 

Though there are ways of constructing Venn diagrams with more than three categories, determining the validity of these arguments using Venn diagrams is very difficult (and often requires computers). These limitations led to the development of more powerful systems of formal reasoning.

b. Propositional Logic

Propositional, or sentential , logic has advantages and disadvantages relative to categorical logic. It is more powerful than categorical logic in that it is not restricted in the number of terms it can evaluate, and therefore, it is not restricted to the syllogistic form. But it is weaker than categorical logic in that it has no operators for quantifying over subjects, such as “all” or “some.” For those, we must appeal to predicate logic (see §3c below).

Basic propositional logic involves formal reasoning about propositions (as opposed to categories), and its most basic unit of evaluation is the atomic proposition . “Atom” means the smallest indivisible unit of something, and simple English statements (subject + predicate) are atomic wholes because if either part is missing, the word or words cease to be a statement, and therefore ceases to be capable of expressing a proposition. Atomic propositions are simple subject-predicate combinations, for instance, “It is a cat” and “I am a mammal.” Variable letters such as p and q in argument forms are replaced with semantically rich constants, indicated by capital letters, such as A and B . Consider modus ponens again (noting that the atomic propositions are underlined in the English argument):

As you can see from premise 1 of the Semantic Replacement, atomic propositions can be combined into more complex propositions using symbols that represent their logical relationships (such as “If…, then…”). These symbols are called “operators” or “connectives.” The five standard operators in basic propositional logic are:

These operations allow us to identify valid relations among propositions: that is, they allow us to formulate a set of rules by which we can validly infer propositions from and validly replace them with others. These rules of inference (such as modus ponens ; modus tollens ; disjunctive syllogism) and rules of replacement (such as double negation; contraposition; DeMorgan’s Law) comprise the syntax of propositional logic, guaranteeing the validity of the arguments employing them.

Two Rules of Inference:

Two Rules of Replacement:

For more, see “ Propositional Logic .”

c. Modal Logic

Standard propositional logic does not capture every type of proposition we wish to express (recall that it does not allow us to evaluate categorical quantifiers such as “all” or “some”). It also does not allow us to evaluate propositions expressed as possibly true or necessarily true, modifications that are called modal operators or modal quantifiers .

Modal logic refers to a family of formal propositional systems, the most prominent of which includes operators for necessity (□) and possibility (◊) (see §3d below for examples of other modal systems). If a proposition, p , is possibly true, ◊ p , it may or may not be true. If p is necessarily true, □ p , it must be true; it cannot be false. If p is necessarily false, either ~◊ p or □~ p , it must be false; it cannot be true.

There is a variety of modal systems, the weakest of which is called K (after Saul Kripke, who exerted important influence on the development of modal logic), and it involves only two additional rules:

Necessitation Rule:   If  A  is a theorem of  K , then so is □ A .

Distribution Axiom:  □( A ⊃ B ) ⊃ (□ A ⊃□ B ).  [If it is necessarily the case that if A, then B , then if it is necessarily the case that A, it is necessarily the case that B .]

Other systems maintain these rules and add others for increasing strength. For instance, the (S4) modal system includes axiom (4):

(4)  □ A ⊃ □□ A   [If it is necessarily the case that A, then it is necessarily necessary that A.]

An influential and intuitive way of thinking about modal concepts is the idea of “possible worlds” (see Plantinga, 1974; Lewis 1986). A world is just the set of all true propositions. The actual world is the set of all actually true propositions—everything that was true, is true, and (depending on what you believe about the future) will be true. A possible world is a way the actual world might have been. Imagine you wore green underwear today. The actual world might have been different in that way: you might have worn blue underwear. In this interpretation of modal quantifiers, there is a possible world in which you wore blue underwear instead of green underwear. And for every possibility like this, and every combination of those possibilities, there is a distinct possible world.

If a proposition is not possible, then there is no possible world in which that proposition is true. The statement, “That object is red all over and blue all over at the same time” is not true in any possible worlds. Therefore, it is not possible (~◊P), or, in other words, necessarily false (□~P). If a proposition is true in all possible worlds, it is necessarily true. For instance, the proposition, “Two plus two equal four,” is true in all possible worlds, so it is necessarily true (□P) or not possibly false (~◊~P).

All modal systems have a number of controversial implications, and there is not space to review them here. Here we need only note that modal logic is a type of formal reasoning that increases the power of propositional logic to capture more of what we attempt to express in natural languages. (For more, see “ Modal Logic: A Contemporary View .”)

d. Predicate Logic

Predicate logic, in particular, first-order predicate logic, is even more powerful than propositional logic. Whereas propositional logic treats propositions as atomic wholes, predicate logic allows reasoners to identify and refer to subjects of propositions, independently of their predicates. For instance, whereas the proposition, “Susan is witty,” would be replaced with a single upper-case letter, say “S,” in propositional logic, predicate logic would assign the subject “Susan” a lower-case letter, s, and the predicate “is witty” an upper-case letter, W, and the translation (or formula ) would be: Ws.

In addition to distinguishing subjects and predicates, first-order predicate logic allows reasoners to quantify over subjects. The quantifiers in predicate logic are “All…,” which is comparable to “All” quantifier in categorical logic and is sometimes symbolized with an upside-down A: ∀ (though it may not be symbolized at all), and “There is at least one…,” which is comparable to “Some” quantifier in categorical logic and is symbolized with a backward E: ∃. E and O claims are formed by employing the negation operator from propositional logic. In this formal system, the proposition, “Someone is witty,” for example, has the form: There is an x , such that x has the property of being witty, which is symbolized: (∃ x)(Wx). Similarly, the proposition, “Everyone is witty,” has the form: For all x, x has the property of being witty, which is symbolized (∀ x )( Wx ) or, without the ∀: ( x )( Wx ).

Predicate derivations are conducted according to the same rules of inference and replacement as propositional logic with the exception of four rules to accommodate adding and eliminating quantifiers.

Second-order predicate logic extends first-order predicate logic to allow critical thinkers to quantify over and draw inferences about subjects and predicates, including relations among subjects and predicates. In both first- and second-order logic, predicates typically take the form of properties (one-place predicates) or relations (two-place predicates), though there is no upper limit on place numbers. Second-order logic allows us to treat both as falling under quantifiers, such as e verything that is (specifically, that has the property of being) a tea cup and everything that is a bachelor is unmarried .

e. Other Formal Systems

It is worth noting here that the formal reasoning systems we have seen thus far (categorical, propositional, and predicate) all presuppose that truth is bivalent , that is, two-valued. The two values critical thinkers are most often concerned with are true and false , but any bivalent system is subject to the rules of inference and replacement of propositional logic. The most common alternative to truth values is the binary code of 1s and 0s used in computer programming. All logics that presuppose bivalence are called classical logics . In the next section, we see that not all formal systems are bivalent; there are non-classical logics . The existence of non-classical systems raises interesting philosophical questions about the nature of truth and the legitimacy of our basic rules of reasoning, but these questions are too far afield for this context. Many philosophers regard bivalent systems as legitimate for all but the most abstract and purely formal contexts. Included below is a brief description of three of the most common non-classical logics.

Tense logic , or temporal logic, is a formal modal system developed by Arthur Prior (1957, 1967, 1968) to accommodate propositional language about time. For example, in addition to standard propositional operators, tense logic includes four operators for indexing times: P “It has at some time been the case that…”; F “It will at some time be the case that…”; H “It has always been the case that…”; and G “It will always be the case that….”

Many-valued logic , or n -valued logic, is a family of formal logical systems that attempts to accommodate intuitions that suggest some propositions have values in addition to true and false. These are often motivated by intuitions that some propositions have neither of the classic truth values; their truth value is indeterminate (not just undeterminable, but neither true nor false), for example, propositions about the future such as, “There will be a sea battle tomorrow.” If the future does not yet exist, there is no fact about the future, and therefore, nothing for a proposition to express.

Fuzzy logic is a type of many-valued logic developed out of Lotfi Zadeh’s (1965) work on mathematical sets. Fuzzy logic attempts to accommodate intuitions that suggest some propositions have truth value in degrees, that is, some degree of truth between true and false. It is motivated by concerns about vagueness in reality, for example whether a certain color is red or some degree of red, or whether some temperature is hot or some degree of hotness.

Formal reasoning plays an important role in critical thinking, but not very often. There are significant limits to how we might use formal tools in our daily lives. If that is true, how do critical thinkers reason well when formal reasoning cannot help? That brings us to informal reasoning.

4. Informal Reasoning

Informal reasoning is inductive , which means that a proposition is inferred (but not derived) from one or more propositions on the basis of the strength provided by the premises (where “strength” means some degree of likelihood less than certainty or some degree of probability less than 1 but greater than 0; a proposition with 0% probability is necessarily false).

Particular premises grant strength to premises to the degree that they reflect certain relationships or structures in the world . For instance, if a particular type of event, p , is known to cause or indicate another type of event, q , then upon encountering an event of type p , we may infer that an event of type q is likely to occur. We may express this relationship among events propositionally as follows:

• Events of type p typically cause or indicate events of type q .
• An event of type p occurred.
• Therefore, an event of type q probably occurred.

If the structure of the world (for instance, natural laws) makes premise 1 true, then, if premise 2 is true, we can reasonably (though not certainly) infer the conclusion.

Unlike formal reasoning, the adequacy of informal reasoning depends on how well the premises reflect relationships or structures in the world. And since we have not experienced every relationship among objects or events or every structure, we cannot infer with certainty that a particular conclusion follows from a true set of premises about these relationships or structures. We can only infer them to some degree of likelihood by determining to the best of our ability either their objective probability or their probability relative to alternative conclusions.

The objective probability of a conclusion refers to how likely, given the way the world is regardless of whether we know it , that conclusion is to be true. The epistemic probability of a conclusion refers to how likely that conclusion is to be true given what we know about the world , or more precisely, given our evidence for its objective likelihood.

Objective probabilities are determined by facts about the world and they are not truths of logic, so we often need evidence for objective probabilities. For instance, imagine you are about to draw a card from a standard playing deck of 52 cards. Given particular assumptions about the world (that this deck contains 52 cards and that one of them is the Ace of Spades), the objective likelihood that you will draw an Ace of Spades is 1/52. These assumptions allow us to calculate the objective probability of drawing an Ace of Spades regardless of whether we have ever drawn a card before. But these are assumptions about the world that are not guaranteed by logic: we have to actually count the cards, to be sure we count accurately and are not dreaming or hallucinating, and that our memory (once we have finished counting) reliably maintains our conclusions. None of these processes logically guarantees true beliefs. So, if our assumptions are correct, we know the objective probability of actually drawing an Ace of Spades in the real world. But since there is no logical guarantee that our assumptions are right, we are left only with the epistemic probability (the probability based on our evidence) of drawing that card. If our assumptions are right, then the objective probability is the same as our epistemic probability: 1/52. But even if we are right, objective and epistemic probabilities can come apart under some circumstances.

Imagine you draw a card without looking at it and lay it face down. What is the objective probability that that card is an Ace of Spades? The structure of the world has now settled the question, though you do not know the outcome. If it is an Ace of Spades, the objective probability is 1 (100%); it is the Ace of Spades. If it is not the Ace of Spades, the objective probability is 0 (0%); it is not the Ace of Spades. But what is the epistemic probability? Since you do not know any more about the world than you did before you drew the card, the epistemic probability is the same as before you drew it: 1/52.

Since much of the way the world is is hidden from us (like the card laid face down), and since it is not obvious that we perceive reality as it actually is (we do not know whether the actual coins we flip are evenly weighted or whether the actual dice we roll are unbiased), our conclusions about probabilities in the actual world are inevitably epistemic probabilities. We can certainly calculate objective probabilities about abstract objects (for instance, hypothetically fair coins and dice—and these calculations can be evaluated formally using probability theory and statistics), but as soon as we apply these calculations to the real world, we must accommodate the fact that our evidence is incomplete.

There are four well-established categories of informal reasoning: generalization, analogy, causal reasoning, and abduction.

a. Generalization

Generalization is a way of reasoning informally from instances of a type to a conclusion about the type. This commonly takes two forms: reasoning from a sample of a population to the whole population , and reasoning from past instances of an object or event to future instances of that object or event . The latter is sometimes called “enumerative induction” because it involves enumerating past instances of a type in order to draw an inference about a future instance. But this distinction is weak; both forms of generalization use past or current data to infer statements about future instances and whole current populations.

A popular instance of inductive generalization is the opinion poll: a sample of a population of people is polled with respect to some statement or belief. For instance, if we poll 57 sophomores enrolled at a particular college about their experiences of living in dorms, these 57 comprise our sample of the population of sophomores at that particular college. We want to be careful how we define our population given who is part of our sample. Not all college students are like sophomores, so it is not prudent to draw inferences about all college students from these sophomores. Similarly, sophomores at other colleges are not necessarily like sophomores at this college (it could be the difference between a liberal arts college and a research university), so it is prudent not to draw inferences about all sophomores from this sample at a particular college.

Let us say that 90% of the 57 sophomores we polled hate the showers in their dorms. From this information, we might generalize in the following way:

• We polled 57 sophomores at Plato’s Academy. (the sample)
• 90% of our sample hates the showers in their dorms. (the polling data)
• Therefore, probably 90% of all sophomores at Plato’s Academy hate the showers in their dorms. (a generalization from our sample to the whole population of sophomores at Plato’s Academy)

Is this good evidence that 90% of all sophomores at that college hate the showers in their dorms?

A generalization is typically regarded as a good argument if its sample is representative of its population. A sample is representative if it is similar in the relevant respects to its population. A perfectly representative sample would include the whole population: the sample would be identical with the population, and thus, perfectly representative. In that case, no generalization is necessary. But we rarely have the time or resources to evaluate whole populations. And so, a sample is generally regarded as representative if it is large relative to its population and unbiased .

In our example, whether our inference is good depends, in part, on how many sophomores there are. Are there 100, 2,000? If there are only 100, then our sample size seems adequate—we have polled over half the population. Is our sample unbiased? That depends on the composition of the sample. Is it comprised only of women or only of men? If this college is not co-ed, that is not a problem. But if the college is co-ed and we have sampled only women, our sample is biased against men. We have information only about female freshmen dorm experiences, and therefore, we cannot generalize about male freshmen dorm experiences.

How large is large enough? This is a difficult question to answer. A poll of 1% of your high school does not seem large enough to be representative. You should probably gather more data. Yet a poll of 1% of your whole country is practically impossible (you are not likely to ever have enough grant money to conduct that poll). But could a poll of less than 1% be acceptable? This question is not easily answered, even by experts in the field. The simple answer is: the more, the better. The more complicated answer is: it depends on how many other factors you can control for, such as bias and hidden variables (see §4c for more on experimental controls).

Similarly, we might ask what counts as an unbiased sample. An overly simple answer is: the sample is taken randomly, that is, by using a procedure that prevents consciously or unconsciously favoring one segment of the population over another (flipping a coin, drawing lottery balls). But reality is not simple. In political polls, it is important not to use a selection procedure that results in a sample with a larger number of members of one political party than another relative to their distribution in the population, even if the resulting sample is random. For example, the two most prominent parties in the U.S. are the Democratic Party and the Republican Party. If 47% of the U.S. is Republican and 53% is Democrat, an unbiased sample would have approximately 47% Republicans and 53% Democrats. But notice that simply choosing at random may not guarantee that result; it could easily occur, just by choosing randomly, that our sample has 70% Democrats and 30% Republicans (suppose our computer chose, albeit randomly, from a highly Democratic neighborhood). Therefore, we want to control for representativeness in some criteria, such as gender, age, and education. And we explicitly want to avoid controlling for the results we are interested in; if we controlled for particular answers to the questions on our poll, we would not learn anything—we would get all and only the answers we controlled for.

Difficulties determining representativeness suggest that reliable generalizations are not easy to construct. If we generalize on the basis of samples that are too small or if we cannot control for bias, we commit the informal fallacy of hasty generalization (see §5b). In order to generalize well, it seems we need a bit of machinery to guarantee representativeness. In fact, it seems we need an experiment, one of the primary tools in causal reasoning (see §4c below).

Argument from Analogy , also called analogical reasoning , is a way of reasoning informally about events or objects based on their similarities. A classic instance of reasoning by analogy occurs in archaeology, when researchers attempt to determine whether a stone object is an artifact (a human-made item) or simply a rock. By comparing the features of an unknown stone with well-known artifacts, archaeologists can infer whether a particular stone is an artifact. Other examples include identifying animals’ tracks by their similarities with pictures in a guidebook and consumer reports on the reliability of products.

To see how arguments from analogy work in detail, imagine two people who, independently of one another, want to buy a new pickup truck. Each chooses a make and model he or she likes, and let us say they decide on the same truck. They then visit a number of consumer reporting websites to read reports on trucks matching the features of the make and model they chose, for instance, the year it was built, the size of the engine (6 cyl. or 8 cyl.), the type of transmission (2WD or 4WD), the fuel mileage, and the cab size (standard, extended, crew). Now, let us say one of our prospective buyers is interested in safety —he or she wants a tough, safe vehicle that will protect against injuries in case of a crash. The other potential buyer is interested in mechanical reliability —he or she does not want to spend a lot of time and money fixing mechanical problems.

With this in mind, here is how our two buyers might reason analogically about whether to purchase the truck (with some fake report data included):

• The truck I have in mind was built in 2012, has a 6-cylinder engine, a 2WD transmission, and a king cab.
• 62 people who bought trucks like this one posted consumer reports and have driven it for more than a year.
• 88% of those 62 people report that the truck feels very safe.
• Therefore, the truck I am looking at will likely be very safe.
• 88% of those 62 people report that the truck has had no mechanical problems.
• Therefore, the truck I am looking at will likely have no mechanical problems.

Are the features of these analogous vehicles (the ones reported on) sufficiently numerous and relevant for helping our prospective truck buyers decide whether to purchase the truck in question (the one on the lot)? Since we have some idea that the type of engine and transmission in a vehicle contribute to its mechanical reliability, Buyer 2 may have some relevant features on which to draw a reliable analogy. Fuel mileage and cab size are not obviously relevant, but engine specifications seem to be. Are these specifications numerous enough? That depends on whether anything else that we are not aware of contributes to overall reliability. Of course, if the trucks having the features we know also have all other relevant features we do not know (if there are any), then Buyer 2 may still be able to draw a reliable inference from analogy. Of course, we do not currently know this.

Alternatively, Buyer 1 seems to have very few relevant features on which to draw a reliable analogy. The features listed are not obviously related to safety. Are there safety options a buyer may choose but that are not included in the list? For example, can a buyer choose side-curtain airbags, or do such airbags come standard in this model? Does cab size contribute to overall safety? Although there are a number of similarities between the trucks, it is not obvious that we have identified features relevant to safety or whether there are enough of them. Further, reports of “feeling safe” are not equivalent to a truck actually being safe. Better evidence would be crash test data or data from actual accidents involving this truck. This information is not likely to be on a consumer reports website.

A further difficulty is that, in many cases, it is difficult to know whether many similarities are necessary if the similarities are relevant. For instance, if having lots of room for passengers is your primary concern, then any other features are relevant only insofar as they affect cab size. The features that affect cab size may be relatively small.

This example shows that arguments from analogy are difficult to formulate well. Arguments from analogy can be good arguments when critical thinkers identify a sufficient number of features of known objects that are also relevant to the feature inferred to be shared by the object in question. If a rock is shaped like a cutting tool, has marks consistent with shaping and sharpening, and has wear marks consistent with being held in a human hand, it is likely that rock is an artifact. But not all cases are as clear.

It is often difficult to determine whether the features we have identified are sufficiently numerous or relevant to our interests. To determine whether an argument from analogy is good, a person may need to identify a causal relationship between those features and the one in which she is interested (as in the case with a vehicle’s mechanical reliability). This usually takes the form of an experiment, which we explore below (§4c).

Difficulties with constructing reliable generalizations and analogies have led critical thinkers to develop sophisticated methods for controlling for the ways these arguments can go wrong. The most common way to avoid the pitfalls of these arguments is to identify the causal structures in the world that account for or underwrite successful generalizations and analogies. Causal arguments are the primary method of controlling for extraneous causal influences and identifying relevant causes. Their development and complexity warrant regarding them as a distinct form of informal reasoning.

c. Causal Reasoning

Causal arguments attempt to draw causal conclusions (that is, statements that express propositions about causes: x causes y ) from premises about relationships among events or objects. Though it is not always possible to construct a causal argument, when available, they have an advantage over other types of inductive arguments in that they can employ mechanisms (experiments) that reduce the risks involved in generalizations and analogies.

The interest in identifying causal relationships often begins with the desire to explain correlations among events (as pollen levels increase, so do allergy symptoms) or with the desire to replicate an event (building muscle, starting a fire) or to eliminate an event (polio, head trauma in football).

Correlations among events may be positive (where each event increases at roughly the same rate) or negative (where one event decreases in proportion to another’s increase). Correlations suggest a causal relationship among the events correlated.

But we must be careful; correlations are merely suggestive—other forces may be at work. Let us say the y-axis in the charts above represents the number of millionaires in the U.S. and the x-axis represents the amount of money U.S. citizens pay for healthcare each year. Without further analysis, a positive correlation between these two may lead someone to conclude that increasing wealth causes people to be more health conscious and to seek medical treatment more often. A negative correlation may lead someone to conclude that wealth makes people healthier and, therefore, that they need to seek medical care less frequently.

Unfortunately, correlations can occur without any causal structures (mere coincidence) or because of a third, as-yet-unidentified event (a cause common to both events, or “common cause”), or the causal relationship may flow in an unexpected direction (what seems like the cause is really the effect). In order to determine precisely which event (if any) is responsible for the correlation, reasoners must eliminate possible influences on the correlation by “controlling” for possible influences on the relationship (variables).

Critical thinking about causes begins by constructing hypotheses about the origins of particular events. A hypothesis is an explanation or event that would account for the event in question. For example, if the question is how to account for increased acne during adolescence, and we are not aware of the existence of hormones, we might formulate a number of hypotheses about why this happens: during adolescence, people’s diets change (parents no longer dictate their meals), so perhaps some types of food cause acne; during adolescence, people become increasingly anxious about how they appear to others, so perhaps anxiety or stress causes acne; and so on.

After we have formulated a hypothesis, we identify a test implication that will help us determine whether our hypothesis is correct. For instance, if some types of food cause acne, we might choose a particular food, say, chocolate, and say: if chocolate causes acne (hypothesis), then decreasing chocolate will decrease acne (test implication). We then conduct an experiment to see whether our test implication occurs.

Reasoning about our experiment would then look like one of the following arguments:

There are a couple of important things to note about these arguments. First, despite appearances, both are inductive arguments. The one on the left commits the formal fallacy of affirming the consequent, so, at best, the premises confer only some degree of probability on the conclusion. The argument on the right looks to be deductive (on the face of it, it has the valid form modus tollens ), but it would be inappropriate to regard it deductively. This is because we are not evaluating a logical connection between H and TI, we are evaluating a causal connection—TI might be true or false regardless of H (we might have chosen an inappropriate test implication or simply gotten lucky), and therefore, we cannot conclude with certainty that H does not causally influence TI. Therefore, “If…, then…” statements in experiments must be read as causal conditionals and not material conditionals (the term for how we used conditionals above).

Second, experiments can go wrong in many ways, so no single experiment will grant a high degree of probability to its causal conclusion. Experiments may be biased by hidden variables (causes we did not consider or detect, such as age, diet, medical history, or lifestyle), auxiliary assumptions (the theoretical assumptions by which evaluating the results may be faulty), or underdetermination (there may be a number of hypotheses consistent with those results; for example, if it is actually sugar that causes acne, then chocolate bars, ice cream, candy, and sodas would yield the same test results). Because of this, experiments either confirm or disconfirm a hypothesis; that is, they give us some reason (but not a particularly strong reason) to believe our hypothesized causes are or are not the causes of our test implications, and therefore, of our observations (see Quine and Ullian, 1978). Because of this, experiments must be conducted many times, and only after we have a number of confirming or disconfirming results can we draw a strong inductive conclusion. (For more, see “ Confirmation and Induction .”)

Experiments may be formal or informal . In formal experiments, critical thinkers exert explicit control over experimental conditions: experimenters choose participants, include or exclude certain variables, and identify or introduce hypothesized events. Test subjects are selected according to control criteria (criteria that may affect the results and, therefore, that we want to mitigate, such as age, diet, and lifestyle) and divided into control groups (groups where the hypothesized cause is absent) and experimental groups (groups where the hypothesized cause is present, either because it is introduced or selected for).

Subjects are then placed in experimental conditions. For instance, in a randomized study, the control group receives a placebo (an inert medium) whereas the experimental group receives the hypothesized cause—the putative cause is introduced, the groups are observed, and the results are recorded and compared. When a hypothesized cause is dangerous (such as smoking) or its effects potentially irreversible (for instance, post-traumatic stress disorder), the experimental design must be restricted to selecting for the hypothesized cause already present in subjects, for example, in retrospective (backward-looking) and prospective (forward-looking) studies. In all types of formal experiments, subjects are observed under exposure to the test or placebo conditions for a specified time, and results are recorded and compared.

In informal experiments, critical thinkers do not have access to sophisticated equipment or facilities and, therefore, cannot exert explicit control over experimental conditions. They are left to make considered judgments about variables. The most common informal experiments are John Stuart Mill’s five methods of inductive reasoning, called Mill’s Methods, which he first formulated in A System of Logic (1843). Here is a very brief summary of Mill’s five methods:

(1) The Method of Agreement

If all conditions containing the event y also contain x , x is probably the cause of y .

For example:

“I’ve eaten from the same box of cereal every day this week, but all the times I got sick after eating cereal were times when I added strawberries. Therefore, the strawberries must be bad.”

(2) The Method of Difference

If all conditions lacking y also lack x , x is probably the cause of y .

“The organization turned all its tax forms in on time for years, that is, until our comptroller, George, left; after that, we were always late. Only after George left were we late. Therefore, George was probably responsible for getting our tax forms in on time.”

(3) The Joint Method of Agreement and Difference

If all conditions containing event y also contain event x , and all events lacking y also lack x , x is probably the cause of y .

“The conditions at the animal shelter have been pretty regular, except we had a string of about four months last year when the dogs barked all night, every night. But at the beginning of those four months we sheltered a redbone coonhound, and the barking stopped right after a family adopted her. All the times the redbone hound wasn’t present, there was no barking. Only the time she was present was there barking. Therefore, she probably incited all the other dogs to bark.”

(4) The Method of Concomitant Variation

If the frequency of event y increases and decreases as event x increases and decreases, respectively, x is probably the cause of y .

“We can predict the amount of alcohol sales by the rate of unemployment. As unemployment rises, so do alcohol sales. As unemployment drops, so do alcohol sales. Last quarter marked the highest unemployment in three years, and our sales last quarter are the highest they had been in those three years. Therefore, unemployment probably causes people to buy alcohol.”

(5) The Method of Residues

If a number of factors x , y , and z , may be responsible for a set of events A , B , and C , and if we discover reasons for thinking that x is the cause of A and y is the cause of B , then we have reason to believe z is the cause of C .

“The people who come through this medical facility are usually starving and have malaria, and a few have polio. We are particularly interested in treating the polio. Take this patient here: she is emaciated, which is caused by starvation; and she has a fever, which is caused by malaria. But notice that her muscles are deteriorating, and her bones are sore. This suggests she also has polio.”

d. Abduction

Not all inductive reasoning is inferential. In some cases, an explanation is needed before we can even begin drawing inferences. Consider Darwin’s idea of natural selection. Natural selection is not an object, like a blood vessel or a cellular wall, and it is not, strictly speaking, a single event. It cannot be detected in individual organisms or observed in a generation of offspring. Natural selection is an explanation of biodiversity that combines the process of heritable variation and environmental pressures to account for biomorphic change over long periods of time. With this explanation in hand, we can begin to draw some inferences. For instance, we can separate members of a single species of fruit flies, allow them to reproduce for several generations, and then observe whether the offspring of the two groups can reproduce. If we discover they cannot reproduce, this is likely due to certain mutations in their body types that prevent them from procreating. And since this is something we would expect if natural selection were true, we have one piece of confirming evidence for natural selection. But how do we know the explanations we come up with are worth our time?

Coined by C. S. Peirce (1839-1914), abduction , also called retroduction, or inference to the best explanation , refers to a way of reasoning informally that provides guidelines for evaluating explanations. Rather than appealing to types of arguments (generalization, analogy, causation), the value of an explanation depends on the theoretical virtues it exemplifies. A theoretical virtue is a quality that renders an explanation more or less fitting as an account of some event. What constitutes fittingness (or “loveliness,” as Peter Lipton (2004) calls it) is controversial, but many of the virtues are intuitively compelling, and abduction is a widely accepted tool of critical thinking.

The most widely recognized theoretical virtue is probably simplicity , historically associated with William of Ockham (1288-1347) and known as Ockham’s Razor . A legend has it that Ockham was asked whether his arguments for God’s existence prove that only one God exists or whether they allow for the possibility that many gods exist. He supposedly responded, “Do not multiply entities beyond necessity.” Though this claim is not found in his writings, Ockham is now famous for advocating that we restrict our beliefs about what is true to only what is absolutely necessary for explaining what we observe.

In contemporary theoretical use, the virtue of simplicity is invoked to encourage caution in how many mechanisms we introduce to explain an event. For example, if natural selection can explain the origin of biological diversity by itself, there is no need to hypothesize both natural selection and a divine designer. But if natural selection cannot explain the origin of, say, the duck-billed platypus, then some other mechanism must be introduced. Of course, not just any mechanism will do. It would not suffice to say the duck-billed platypus is explained by natural selection plus gremlins. Just why this is the case depends on other theoretical virtues; ideally, the virtues work together to help critical thinkers decide among competing hypotheses to test. Here is a brief sketch of some other theoretical virtues or ideals:

Conservatism – a good explanation does not contradict well-established views in a field.

Independent Testability – a good explanation is successful on different occasions under similar circumstances.

Fecundity – a good explanation leads to results that make even more research possible.

Explanatory Depth – a good explanation provides details of how an event occurs.

Explanatory Breadth – a good explanation also explains other, similar events.

Though abduction is structurally distinct from other inductive arguments, it functions similarly in practice: a good explanation provides a probabilistic reason to believe a proposition. This is why it is included here as a species of inductive reasoning. It might be thought that explanations only function to help critical thinkers formulate hypotheses, and do not, strictly speaking, support propositions. But there are intuitive examples of explanations that support propositions independently of however else they may be used. For example, a critical thinker may argue that material objects exist outside our minds is a better explanation of why we perceive what we do (and therefore, a reason to believe it) than that an evil demon is deceiving me , even if there is no inductive or deductive argument sufficient for believing that the latter is false. (For more, see “ Charles Sanders Peirce: Logic .”)

5. Detecting Poor Reasoning

Our attempts at thinking critically often go wrong, whether we are formulating our own arguments or evaluating the arguments of others. Sometimes it is in our interests for our reasoning to go wrong, such as when we would prefer someone to agree with us than to discover the truth value of a proposition. Other times it is not in our interests; we are genuinely interested in the truth, but we have unwittingly made a mistake in inferring one proposition from others. Whether our errors in reasoning are intentional or unintentional, such errors are called fallacies (from the Latin, fallax, which means “deceptive”). Recognizing and avoiding fallacies helps prevent critical thinkers from forming or maintaining defective beliefs.

Fallacies occur in a number of ways. An argument’s form may seem to us valid when it is not, resulting in a formal fallacy . Alternatively, an argument’s premises may seem to support its conclusion strongly but, due to some subtlety of meaning, do not, resulting in an informal fallacy . Additionally, some of our errors may be due to unconscious reasoning processes that may have been helpful in our evolutionary history, but do not function reliably in higher order reasoning. These unconscious reasoning processes are now widely known as heuristics and biases . Each type is briefly explained below.

a. Formal Fallacies

Formal fallacies occur when the form of an argument is presumed or seems to be valid (whether intentionally or unintentionally) when it is not. Formal fallacies are usually invalid variations of valid argument forms. Consider, for example, the valid argument form modus ponens (this is one of the rules of inference mentioned in §3b):

modus ponens (valid argument form)

In modus ponens , we assume or “affirm” both the conditional and the left half of the conditional (called the antecedent ): (p à q) and p. From these, we can infer that q, the second half or consequent , is true. This a valid argument form: if the premises are true, the conclusion cannot be false.

Sometimes, however, we invert the conclusion and the second premise, affirming that the conditional, (p à q), and the right half of the conditional, q (the consequent), are true, and then inferring that the left half, p (the antecedent), is true. Note in the example below how the conclusion and second premise are switched. Switching them in this way creates a problem.

To get an intuitive sense of why “affirming the consequent” is a problem, consider this simple example:

affirming the consequent

• It is a mammal.
• Therefore, it is a cat.(?)

From the fact that something is a mammal, we cannot conclude that it is a cat. It may be a dog or a mouse or a whale. The premises can be true and yet the conclusion can still be false. Therefore, this is not a valid argument form. But since it is an easy mistake to make, it is included in the set of common formal fallacies.

Here is a second example with the rule of inference called modus tollens . Modus tollens involves affirming a conditional, (p à q), and denying that conditional’s consequent: ~q. From these two premises, we can validly infer the denial of the antecedent: ~p. But if we switch the conclusion and the second premise, we get another fallacy, called denying the antecedent .

Technically, all informal reasoning is formally fallacious—all informal arguments are invalid. Nevertheless, since those who offer inductive arguments rarely presume they are valid, we do not regard them as reasoning fallaciously.

b. Informal Fallacies

Informal fallacies occur when the meaning of the terms used in the premises of an argument suggest a conclusion that does not actually follow from them (the conclusion either follows weakly or with no strength at all). Consider an example of the informal fallacy of equivocation , in which a word with two distinct meanings is used in both of its meanings:

• Any law can be repealed by Congress.
• Gravity is a law.
• Therefore, gravity can be repealed by Congress.

In this case, the argument’s premises are true when the word “law” is rightly interpreted, but the conclusion does not follow because the word law has a different referent in premise 1 (political laws) than in premise 2 (a law of nature). This argument equivocates on the meaning of law and is, therefore, fallacious.

Consider, also, the informal fallacy of ad hominem , abusive, when an arguer appeals to a person’s character as a reason to reject her proposition:

“Elizabeth argues that humans do not have souls; they are simply material beings. But Elizabeth is a terrible person and often talks down to children and the elderly. Therefore, she could not be right that humans do not have souls.”

The argument might look like this:

• Elizabeth is a terrible person and often talks down to children and the elderly.
• Therefore, Elizabeth is not right that humans do not have souls.

The conclusion does not follow because whether Elizabeth is a terrible person is irrelevant to the truth of the proposition that humans do not have souls. Elizabeth’s argument for this statement is relevant, but her character is not.

Another way to evaluate this fallacy is to note that, as the argument stands, it is an enthymeme (see §2); it is missing a crucial premise, namely: If anyone is a terrible person, that person makes false statements. But this premise is clearly false. There are many ways in which one can be a terrible person, and not all of them imply that someone makes false statements. (In fact, someone could be terrible precisely because they are viciously honest.) Once we fill in the missing premise, we see the argument is not cogent because at least one premise is false.

Importantly, we face a number of informal fallacies on a daily basis, and without the ability to recognize them, their regularity can make them seem legitimate. Here are three others that only scratch the surface:

Appeal to the People: We are often encouraged to believe or do something just because everyone else does. We are encouraged to believe what our political party believes, what the people in our churches or synagogues or mosques believe, what people in our family believe, and so on. We are encouraged to buy things because they are “bestsellers” (lots of people buy them). But the fact that lots of people believe or do something is not, on its own, a reason to believe or do what they do.

Tu Quoque (You, too!): We are often discouraged from pursuing a conclusion or action if our own beliefs or actions are inconsistent with them. For instance, if someone attempts to argue that everyone should stop smoking, but that person smokes, their argument is often given less weight: “Well, you smoke! Why should everyone else quit?” But the fact that someone believes or does something inconsistent with what they advocate does not, by itself, discredit the argument. Hypocrites may have very strong arguments despite their personal inconsistencies.

Base Rate Neglect: It is easy to look at what happens after we do something or enact a policy and conclude that the act or policy caused those effects. Consider a law reducing speed limits from 75 mph to 55 mph in order to reduce highway accidents. And, in fact, in the three years after the reduction, highway accidents dropped 30%! This seems like a direct effect of the reduction. However, this is not the whole story. Imagine you looked back at the three years prior to the law and discovered that accidents had dropped 30% over that time, too. If that happened, it might not actually be the law that caused the reduction in accidents. The law did not change the trend in accident reduction. If we only look at the evidence after the law, we are neglecting the rate at which the event occurred without the law. The base rate of an event is the rate that the event occurs without the potential cause under consideration. To take another example, imagine you start taking cold medicine, and your cold goes away in a week. Did the cold medicine cause your cold to go away? That depends on how long colds normally last and when you took the medicine. In order to determine whether a potential cause had the effect you suspect, do not neglect to compare its putative effects with the effects observed without that cause.

For more on formal and informal fallacies and over 200 different types with examples, see “ Fallacies .”

c. Heuristics and Biases

In the 1960s, psychologists began to suspect there is more to human reasoning than conscious inference. Daniel Kahneman and Amos Tversky confirmed these suspicions with their discoveries that many of the standard assumptions about how humans reason in practice are unjustified. In fact, humans regularly violate these standard assumptions, the most significant for philosophers and economists being that humans are fairly good at calculating the costs and benefits of their behavior; that is, they naturally reason according to the dictates of Expected Utility Theory. Kahneman and Tversky showed that, in practice, reasoning is affected by many non-rational influences, such as the wording used to frame scenarios (framing bias) and information most vividly available to them (the availability heuristic).

Consider the difference in your belief about the likelihood of getting robbed before and after seeing a news report about a recent robbery, or the difference in your belief about whether you will be bitten by a shark the week before and after Discovery Channel’s “Shark Week.” For most of us, we are likely to regard their likelihood as higher after we have seen these things on television than before. Objectively, they are no more or less likely to happen regardless of our seeing them on television, but we perceive they are more likely because their possibility is more vivid to us. These are examples of the availability heuristic.

Since the 1960s, experimental psychologists and economists have conducted extensive research revealing dozens of these unconscious reasoning processes, including ordering bias , the representativeness heuristic , confirmation bias , attentional bias , and the anchoring effect . The field of behavioral economics, made popular by Dan Ariely (2008; 2010; 2012) and Richard Thaler and Cass Sunstein (2009), emerged from and contributes to heuristics and biases research and applies its insights to social and economic behaviors.

Ideally, recognizing and understanding these unconscious, non-rational reasoning processes will help us mitigate their undermining influence on our reasoning abilities (Gigerenzer, 2003). However, it is unclear whether we can simply choose to overcome them or whether we have to construct mechanisms that mitigate their influence (for instance, using double-blind experiments to prevent confirmation bias).

6. The Scope and Virtues of Good Reasoning

Whether the process of critical thinking is productive for reasoners—that is, whether it actually answers the questions they are interested in answering—often depends on a number of linguistic, psychological, and social factors. We encountered some of the linguistic factors in §1. In closing, let us consider some of the psychological and social factors that affect the success of applying the tools of critical thinking.

Not all psychological and social contexts are conducive for effective critical thinking. When reasoners are depressed or sad or otherwise emotionally overwhelmed, critical thinking can often be unproductive or counterproductive. For instance, if someone’s child has just died, it would be unproductive (not to mention cruel) to press the philosophical question of why a good God would permit innocents to suffer or whether the child might possibly have a soul that could persist beyond death. Other instances need not be so extreme to make the same point: your company’s holiday party (where most people would rather remain cordial and superficial) is probably not the most productive context in which to debate the president’s domestic policy or the morality of abortion.

The process of critical thinking is primarily about detecting truth, and truth may not always be of paramount value. In some cases, comfort or usefulness may take precedence over truth. The case of the loss of a child is a case where comfort seems to take precedence over truth. Similarly, consider the case of determining what the speed limit should be on interstate highways. Imagine we are trying to decide whether it is better to allow drivers to travel at 75 mph or to restrict them to 65. To be sure, there may be no fact of the matter as to which is morally better, and there may not be any difference in the rate of interstate deaths between states that set the limit at 65 and those that set it at 75. But given the nature of the law, a decision about which speed limit to set must be made. If there is no relevant difference between setting the limit at 65 and setting it at 75, critical thinking can only tell us that , not which speed limit to set. This shows that, in some cases, concern with truth gives way to practical or preferential concerns (for example, Should I make this decision on the basis of what will make citizens happy? Should I base it on whether I will receive more campaign contributions from the business community?). All of this suggests that critical thinking is most productive in contexts where participants are already interested in truth.

b. The Principle of Charity/Humility

Critical thinking is also most productive when people in the conversation regard themselves as fallible, subject to error, misinformation, and deception. The desire to be “right” has a powerful influence on our reasoning behavior. It is so strong that our minds bias us in favor of the beliefs we already hold even in the face of disconfirming evidence (a phenomenon known as “confirmation bias”). In his famous article, “The Ethics of Belief” (1878), W. K. Clifford notes that, “We feel much happier and more secure when we think we know precisely what to do, no matter what happens, than when we have lost our way and do not know where to turn. … It is the sense of power attached to a sense of knowing that makes men desirous of believing, and afraid of doubting” (2010: 354).

Nevertheless, when we are open to the possibility that we are wrong, that is, if we are humble about our conclusions and we interpret others charitably, we have a better chance at having rational beliefs in two senses. First, if we are genuinely willing to consider evidence that we are wrong—and we demonstrate that humility—then we are more likely to listen to others when they raise arguments against our beliefs. If we are certain we are right, there would be little reason to consider contrary evidence. But if we are willing to hear it, we may discover that we really are wrong and give up faulty beliefs for more reasonable ones.

Second, if we are willing to be charitable to arguments against our beliefs, then if our beliefs are unreasonable, we have an opportunity to see the ways in which they are unreasonable. On the other hand, if our beliefs are reasonable, then we can explain more effectively just how well they stand against the criticism. This is weakly analogous to competition in certain types of sporting events, such as basketball. If you only play teams that are far inferior to your own, you do not know how good your team really is. But if you can beat a well-respected team on fair terms, any confidence you have is justified.

c. The Principle of Caution

In our excitement over good arguments, it is easy to overextend our conclusions, that is, to infer statements that are not really warranted by our evidence. From an argument for a first, uncaused cause of the universe, it is tempting to infer the existence of a sophisticated deity such as that of the Judeo-Christian tradition. From an argument for the compatibilism of the free will necessary for moral responsibility and determinism, it is tempting to infer that we are actually morally responsible for our behaviors. From an argument for negative natural rights, it is tempting to infer that no violation of a natural right is justifiable. Therefore, it is prudent to continually check our conclusions to be sure they do not include more content than our premises allow us to infer.

Of course, the principle of caution must itself be used with caution. If applied too strictly, it may lead reasoners to suspend all belief, and refrain from interacting with one another and their world. This is not, strictly speaking, problematic; ancient skeptics, such as the Pyrrhonians, advocated suspending all judgments except those about appearances in hopes of experiencing tranquility. However, at least some judgments about the long-term benefits and harms seem indispensable even for tranquility, for instance, whether we should retaliate in self-defense against an attacker or whether we should try to help a loved one who is addicted to drugs or alcohol.

d. The Expansiveness of Critical Thinking

The importance of critical thinking cannot be overstated because its relevance extends into every area of life, from politics, to science, to religion, to ethics. Not only does critical thinking help us draw inferences for ourselves, it helps us identify and evaluate the assumptions behind statements, the moral implications of statements, and the ideologies to which some statements commit us. This can be a disquieting and difficult process because it forces us to wrestle with preconceptions that might not be accurate. Nevertheless, if the process is conducted well, it can open new opportunities for dialogue, sometimes called “critical spaces,” that allow people who might otherwise disagree to find beliefs in common from which to engage in a more productive conversation.

It is this possibility of creating critical spaces that allows philosophical approaches like Critical Theory to effectively challenge the way social, political, and philosophical debates are framed. For example, if a discussion about race or gender or sexuality or gender is framed in terms that, because of the origins those terms or the way they have functioned socially, alienate or disproportionately exclude certain members of the population, then critical space is necessary for being able to evaluate that framing so that a more productive dialogue can occur (see Foresman, Fosl, and Watson, 2010, ch. 10 for more on how critical thinking and Critical Theory can be mutually supportive).

e. Productivity and the Limits of Rationality

Despite the fact that critical thinking extends into every area of life, not every important aspect of our lives is easily or productively subjected to the tools of language and logic. Thinkers who are tempted to subject everything to the cold light of reason may discover they miss some of what is deeply enjoyable about living. The psychologist Abraham Maslow writes, “I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail” (1966: 16). But it is helpful to remember that language and logic are tools, not the projects themselves. Even formal reasoning systems depend on axioms that are not provable within their own systems (consider Euclidean geometry or Peano arithmetic). We must make some decisions about what beliefs to accept and how to live our lives on the basis of considerations outside of critical thinking.

Borrowing an example from William James (1896), consider the statement, “Religion X is true.” James says that, while some people find this statement interesting, and therefore, worth thinking critically about, others may not be able to consider the truth of the statement. For any particular religious tradition, we might not know enough about it to form a belief one way or the other, and even suspending judgment may be difficult, since it is not obvious what we are suspending judgment about.

If I say to you: ‘Be a theosophist or be a Mohammedan,’ it is probably a dead option, because for you neither hypothesis is likely to be alive. But if I say: ‘Be an agnostic or be a Christian,’ it is otherwise: trained as you are, each hypothesis makes some appeal, however small, to your belief (2010: 357).

Ignoring the circularity in his definition of “dead option,” James’s point seems to be that if you know nothing about a view or what statements it entails, no amount of logic or evidence could help you form a reasonable belief about that position.

We might criticize James at this point because his conclusion seems to imply that we have no duty to investigate dead options, that is, to discover if there is anything worth considering in them. If we are concerned with truth, the simple fact that we are not familiar with a proposition does not mean it is not true or potentially significant for us. But James’s argument is subtler than this criticism suggests. Even if you came to learn about a particularly foreign religious tradition, its tenets may be so contrary to your understanding of the world that you could not entertain them as possible beliefs of yours . For instance, you know perfectly well that, if some events had been different, Hitler would not have existed: his parents might have had no children, or his parents’ parents might have had no children. You know roughly what it would mean for Hitler not to have existed and the sort of events that could have made it true that he did not exist. But how much evidence would it take to convince you that, in fact, Hitler did not exist, that is, that your belief that Hitler did exist is false ? Could there be an argument strong enough? Not obviously. Since all the information we have about Hitler unequivocally points to his existence, any arguments against that belief would have to affect a very broad range of statements; they would have to be strong enough to make us skeptical of large parts of reality.

7. Approaches to Improving Reasoning through Critical Thinking

Recall that the goal of critical thinking is not just to study what makes reasons and statements good, but to help us improve our ability to reason, that is, to improve our ability to form, hold, and discard beliefs according to whether they meet the standards of good thinking. Some ways of approaching this latter goal are more effective than others. While the classical approach focuses on technical reasoning skills, the Paul/Elder model encourages us to think in terms of critical concepts, and irrationality approaches use empirical research on instances of poor reasoning to help us improve reasoning where it is least obvious we need it and where we need it most. Which approach or combination of approaches is most effective depends, as noted above, on the context and limits of critical thinking, but also on scientific evidence of their effectiveness. Those who teach critical thinking, of all people, should be engaged with the evidence relevant to determining which approaches are most effective.

a. Classical Approaches

The classic approach to critical thinking follows roughly the structure of this article: critical thinkers attempt to interpret statements or arguments clearly and charitably, and then they apply the tools of formal and informal logic and science, while carefully attempting to avoid fallacious inferences (see Weston, 2008; Walton, 2008; Watson and Arp, 2015). This approach requires spending extensive time learning and practicing technical reasoning strategies. It presupposes that reasoning is primarily a conscious activity, and that enhancing our skills in these areas will improve our ability to reason well in ordinary situations.

There are at least two concerns about this approach. First, it is highly time intensive relative to its payoff. Learning the terminology of systems like propositional and categorical logic and the names of the fallacies, and practicing applying these tools to hypothetical cases requires significant time and energy. And it is not obvious, given the problems with heuristics and biases, whether this practice alone makes us better reasoners in ordinary contexts. Second, many of the ways we reason poorly are not consciously accessible (recall the heuristics and biases discussion in §5c). Our biases, combined with the heuristics we rely on in ordinary situations, can only be detected in experimental settings, and addressing them requires restructuring the ways in which we engage with evidence (see Thaler and Sunstein, 2009).

b. The Paul/Elder Model

Richard Paul and Linda Elder (Paul and Elder, 2006; Paul, 2012) developed an alternative to the classical approach on the assumption that critical thinking is not something that is limited to academic study or to the discipline of philosophy. On their account, critical thinking is a broad set of conceptual skills and habits aimed at a set of standards that are widely regarded as virtues of thinking: clarity, accuracy, depth, fairness, and others. They define it simply as “the art of analyzing and evaluating thinking with a view to improving it” (2006: 4). Their approach, then, is to focus on the elements of thought and intellectual virtues that help us form beliefs that meet these standards.

The Paul/Elder model is made up of three sets of concepts: elements of thought, intellectual standards, and intellectual traits. In this model, we begin by identifying the features present in every act of thought. They use “thought” to mean critical thought aimed at forming beliefs, not just any act of thinking, musing, wishing, hoping, remembering. According to the model, every act of thought involves:

These comprise the subject matter of critical thinking; that is, they are what we are evaluating when we are thinking critically. We then engage with this subject matter by subjecting them to what Paul and Elder call universal intellectual standards. These are evaluative goals we should be aiming at with our thinking:

While in classical approaches, logic is the predominant means of thinking critically, in the Paul/Elder model, it is put on equal footing with eight other standards. Finally, Paul and Elder argue that it is helpful to approach the critical thinking process with a set of intellectual traits or virtues that dispose us to using elements and standards well.

To remind us that these are virtues of thought relevant to critical thinking, they use “intellectual” to distinguish these traits from their moral counterparts (moral integrity, moral courage, and so on).

The aim is that, as we become familiar with these three sets of concepts and apply them in everyday contexts, we become better at analyzing and evaluating statements and arguments in ordinary situations.

Like the classical approach, this approach presupposes that reasoning is primarily a conscious activity, and that enhancing our skills will improve our reasoning. This means that it still lacks the ability to address the empirical evidence that many of our reasoning errors cannot be consciously detected or corrected. It differs from the classical approach in that it gives the technical tools of logic a much less prominent role and places emphasis on a broader, and perhaps more intuitive, set of conceptual tools. Learning and learning to apply these concepts still requires a great deal of time and energy, though perhaps less than learning formal and informal logic. And these concepts are easy to translate into disciplines outside philosophy. Students of history, psychology, and economics can more easily recognize the relevance of asking questions about an author’s point of view and assumptions than perhaps determining whether the author is making a deductive or inductive argument. The question, then, is whether this approach improves our ability to think better than the classical approach.

c. Other Approaches

A third approach that is becoming popular is to focus on the ways we commonly reason poorly and then attempt to correct them. This can be called the Rationality Approach , and it takes seriously the empirical evidence (§5c) that many of our errors in reasoning are not due to a lack of conscious competence with technical skills or misusing those skills, but are due to subconscious dispositions to ignore or dismiss relevant information or to rely on irrelevant information.

One way to pursue this approach is to focus on beliefs that are statistically rare or “weird.” These include beliefs of fringe groups, such as conspiracy theorists, religious extremists, paranormal psychologists, and proponents of New Age metaphysics (see Gilovich, 1992; Vaughn and Schick, 2010; Coady, 2012). If we recognize the sorts of tendencies that lead to these controversial beliefs, we might be able to recognize and avoid similar tendencies in our own reasoning about less extreme beliefs, such as beliefs about financial investing, how statistics are used to justify business decisions, and beliefs about which public policies to vote for.

Another way to pursue this approach is to focus directly on the research on error, those ordinary beliefs that psychologists and behavioral economists have discovered we reason poorly, and to explore ways of changing how we frame decisions about what to believe (see Nisbett and Ross, 1980; Gilovich, 1992; Ariely, 2008; Kahneman, 2011). For example, in one study, psychologists found that judges issue more convictions just before lunch and the end of the day than in the morning or just after lunch (Danzinger, et al., 2010). Given that dockets do not typically organize cases from less significant crimes to more significant crimes, this evidence suggests that something as irrelevant as hunger can bias judicial decisions. Even though hunger has nothing to do with the truth of a belief, knowing that it can affect how we evaluate a belief can help us avoid that effect. This study might suggest something as simple as that we should avoid being hungry when making important decisions. The more we learn ways in which our brains use irrelevant information, the better we can organize our reasoning to avoid these mistakes. For more on how decisions can be improved by restructuring our decisions, see Thaler and Sunstein, 2009.

A fourth approach is to take more seriously the role that language plays in our reasoning. Arguments involve complex patterns of expression, and we have already seen how vagueness and ambiguity can undermine good reasoning (§1). The pragma-dialectics approach (or pragma-dialectical theory) is the view that the quality of an argument is not solely or even primarily a matter of its logical structure, but is more fundamentally a matter of whether it is a form of reasonable discourse (Van Eemeren and Grootendorst, 1992). The proponents of this view contend that, “The study of argumentation should … be construed as a special branch of linguistic pragmatics in which descriptive and normative perspectives on argumentative discourse are methodically integrated” (Van Eemeren and Grootendorst, 1995: 130).

The pragma-dialectics approach is a highly technical approach that uses insights from speech act theory, H. P. Grice’s philosophy of language, and the study of discourse analysis. Its use, therefore, requires a great deal of background in philosophy and linguistics. It has an advantage over other approaches in that it highlights social and practical dimensions of arguments that other approaches largely ignore. For example, argument is often public ( external ), in that it creates an opportunity for opposition, which influences people’s motives and psychological attitudes toward their arguments. Argument is also social in that it is part of a discourse in which two or more people try to arrive at an agreement. Argument is also functional ; it aims at a resolution that can only be accommodated by addressing all the aspects of disagreement or anticipated disagreement, which can include public and social elements. Argument also has a rhetorical role ( dialectical ) in that it is aimed at actually convincing others, which may have different requirements than simply identifying the conditions under which they should be convinced.

These four approaches are not mutually exclusive. All of them presuppose, for example, the importance of inductive reasoning and scientific evidence. Their distinctions turn largely on which aspects of statements and arguments should take precedence in the critical thinking process and on what information will help us have better beliefs.

16 Critical Thinking Examples in Real Life

What is critical thinking.

While making your academic assignments or thesis, you are required to do some research and analyze various things, or for making a career decision or any other decision you are required to think of all pros and cons of that decision. Well, the most important thing that helps us to effectively take these decisions is what we call critical thinking. Critical thinking is very important in both personal and professional life. The process of critical thinking involves the analysis of the various facts and figures in a particular situation before straightaway acting on that situation. Critical thinking demands keen observation, creativity, problem-solving skills, which helps the individual to thoroughly evaluate the gathered information and then use this available information as a guide to making accurate decisions. From doing academic works or regular activities to solving various large scale problems, critical thinking is required in everyday life. In this article, we will learn about some real-life examples where critical thinking plays an important role.

Critical Thinking Examples in Real Life

1. critical thinking in problem solving.

Suppose your manager asks you to find an effective solution to a problem that is affecting the business. What would be your first step? Like most people, you may also start looking for potential solutions to deal with that situation. Well, one requires the use of critical thinking here. Before looking for the solution one needs to take a step back and try to understand the cause of the problem first. One should ask for the opinions of the other people that how does this particular problem impact them and the overall business. If you arrive at a solution, you should not only just rely on one solution, instead, you should always have various backup plans in case the first solution does not work as expected. Most people feel that they are great at problem-solving, but if one is not following all these above discussed steps before making a final judgement, he/she is not a critical thinker. Critical thinking allows people to find the best possible solution to any problem. Critical thinking is an important factor of problem-solving skills, one needs to look at any situation from multiple perspectives because in some cases, your decisions not only impact you but also the people in your surrounding.

2. Critical Thinking in Analysing Risks

Risk assessment is another important factor, which requires the use of critical thinking. Risk assessment is required in various sectors, from children analysing the impact of eating junk food on their health to large businesses in analysing the impact of certain policies on the growth of the company. Let us understand the implication of critical thinking in analysing the risks with some examples.

3. Critical Thinking in Data Analysis

Whether analysing the performance of the children in the schools or analysing the business growth of a multi-national company, the skill of data analysis is very crucial. In today’s era, almost every sector demands experts that can accurately evaluate the available data or information and draw out effective conclusions from it. With the rise in technology, the various tasks of the data analysis such as finding profit and loss, creating balance sheets, and issuing invoices are done with the help of various software, but it does not mean that human skill is not required. Various kinds of software can just convert a large amount of data into some simpler and readable format, but it is the critical thinking of the humans that is required to effectively interpret the data and apply the obtained insight for the benefits. The data analysis can even help us to estimate the future trends and potential risks of taking any decisions.

4. Critical Thinking in Hiring Employees

The ability to objectively view any situation without getting influenced by your personal beliefs or thoughts is one of the important characteristics of critical thinking. In business, the hiring managers require critical thinking to evaluate a large number of resume’s to choose the suitable candidates for the required position. Critical thinking here enables the hiring managers not to hire a candidate on the basis of various factors like gender, age, religion or country, these factors may influence the hiring managers unconsciously. The hiring manager may tend to choose the candidate on his/her subjective beliefs if he/she does not use critical thinking. Hence, critical thinking can help HR’s to hire the best employees that may eventually lead to the growth of the company.

5. Promoting the Teamwork

In a team, every individual is unique and has his/her different ideas to tackle the proposed problem. It is the responsibility of the team leader to understand the perspective of each member and encourage them to work collectively to solve the common problem. You may find the opinion of the other members of your team as ineffective, but instead of straightway denying their opinions one should logically analyse their suggestions and try to put your point of view regarding the problem in an effective and calm manner. If the team leader does not use critical thinking, instead, he/she boost his/her opinions on others, the team is sure to collapse.

6. Critical Thinking in Self-Evaluation

Critical thinking plays a major role in self-evaluation. The knowledge of critical thinking skills allows you to accurately analyse your performance by controlling various subjective biases. People should always evaluate their reactions towards any situation and the way they think, this may help them to get a deep insight into their thought processes, hence improving their thinking abilities to take accurate decisions. Self-evaluation is very important in professional life too. Suppose your manager has set a new target for the company. Every employee is thus required to analyse his/her contribution to the company and try to accomplish the set target. If you know your contribution to the company, it will help you to analyse your performance, and you can try to improve your performance in the areas where you lag.

7. Critical Thinking in Choosing the Career

Almost all of us face various dilemmas in our lives such as choosing the stream, the type of job, choosing between the regular college degree or the online programme. Whatever you choose, every option has its pros and cons. However, critical thinking allows us to accurately weigh the positives and negatives of each option and choose the one that offers more benefits than drawbacks. The best way to do this is to make a list of the pros and the cons and then analyse. Well, this is not just limited to choosing the career path, it can be used in other situations also such as professionally, and financially. One can list the pros and cons of selecting to work in a specific company or choosing the right insurance plan. It is often seen that our choices are greatly influenced by the choices of our friends or known, but one should understand that every individual’s beliefs, desires, and ambitions are different so, if the particular carrear or job is best for the others it does not mean that it would be the best option for you also. Hence, to choose the right carrear path, one requires critical thinking.

8. Critical Thinking in Time Management

Time is the most valuable asset that we have, hence utilizing it appropriately is very crucial. Critical thinking in time management helps you to wisely plan your schedule according to the importance of the particular task or the activity. For example, if the task to which you devote most of your time, is not giving you much return then you need to reconsider your schedule and should devote more time to the tasks that give you high returns.

9. Critical Thinking in Analysing the Fake News

Suppose, one of your friends shares a piece of news with you. Do you bother to analyse that whether this piece of news is real or not? Many of us just believe in the news and shares this with others too without thinking that this can be fake news too. A study conducted by Stanford University showed that around 82 per cent of the teenagers failed to distinguish between the real news and the advertisement with the ‘sponsored content’ label. This problem arises because the standard education curriculum does not emphasise much on critical thinking skills much because of the assumption that critical thinking is inbuilt in every person. By introducing certain lessons or activities that may help to increase the knowledge or overall thinking skills, the critical thinking of the children can be improved. Well, it is also seen that not only children, but adults also fall for these fake news and articles that circulate on various social media platforms. Before believing any piece of information, one should think of various questions like the source of the publication, the intention of the article, the author of the article, and the agenda behind the article. Critical thinking helps us to precisely evaluate any information before straightway believing it.

10. Critical Thinking in Distinguishing between Right and Wrong

Most people, especially teenagers are very much conscious about what their friends or relatives think of their behaviour. You may have had been through the situation, wherein if your friends think that certain behaviour is cool then you start acting in that way to fit in your friend’s circle without even considering that what you are doing is good or bad, and is your actions are related to your beliefs or not? One should understand that if a certain behaviour seems cool to some people, it may also seem bad to some others. One should not change his/her actions depending upon the approval of certain people, rather one should look at the broader aspect and should deeply analyse that whether their actions are morally right or wrong.

11. Critical Thinking in Decoding Fashion Trends

Nowadays, some people are so crazy about following the latest fashion trends, they start following every trend that some popular actor, actress, or fashion influencer suggest. If you are a critical thinker you may have had thought of the questions like why the particular trend that was so popular a few years back seems foolish now? why does a particular trend that does not even look good is so popular? Do the particular fashion trend that suits the other person suits yourself or not? Critical thinking helps people from falling victim to the bandwagon fallacy; it is fallacy in which people starts believing a particular thing or idea as good or bad if the majority of the population thinks so. Fashion trends are a common example of bandwagon fallacy.

12. Critical Thinking in Choosing the Suitable Diet and Exercise

You must have heard of various types of diets such as the Keto diet, Whole 30 diet, Gluten-free diet, Vegan diet and so on. It seems complex to choose the diet that is best for you. What people usually do is that they search online, go through several videos and choose the diet that showed the best results to the person in the video. Well, this is not the right approach, choosing the best diet for yourself requires critical thinking. People who use critical thinking evaluate the pros and cons of the particular diet on their own body, they generally ask about the suitable diet from professional dieticians rather than just following the advice of a random person online. Like choosing a suitable diet, choosing a suitable exercise also demands critical thinking. For example, What are your goals? How can you achieve this? At what time you can do exercise? Do you have any injuries that may get affected by the particular exercise? People who use critical thinking tend to ask all these questions, and then by utilizing the knowledge they have and the following routine for a few weeks, and by analyzing the results they are getting from it, they finally plan a proper schedule for them.

13. Critical Thinking in Online Shopping

In today’s digital era, online shopping is preferred by most people. However, there are various tactics and psychological tricks such as the anchoring effect , Stroop effect , and Serial position effect that are used by the various e-commerce websites, which makes the customers buy more things or things that they don’t even need. Critical thinking can help people to smartly buy items without falling victim to all these effects or tactics. While making the purchase you should focus on the price that you are paying for the particular item rather than the discount you are getting on that item because the chances are that the price that you are paying for that item is not worth paying even after the discount.

14. Critical Thinking in Job Search

Critical thinking plays an important role in the Job search. If you are applying for a job, you may consider the following points to get the desired job.

Use of Keywords in Resume: One should always understand the job post and its requirements before straightaway applying for the job. It is important to update your resume according to the job and add some keywords (mentioned in the job requirements) into your resume to get the job. If you possess some critical thinking skills such as problem-solving, analytical, communication, or creativity skills, it is better to put that in your resume. However, one should always restrain from adding any random critical thinking skills that you do not possess.

Cover Letter: Hiring managers receive hundreds of resumes daily, hence the chances that they will read every resume are quite less. Well, you can make your resume different from others by adding a good cover letter. You can add some of the critical skills that you have to your resume, it is better to explain a little about the tasks or activities where you showed these skills in your previous jobs or work experiences rather than just simply writing the skill. This assures the recruiter that you are not randomly writing the skills and you possess these qualities.

Interviews: Nowadays, some interviewers present the interviewees with hypothetical stories to check their critical thinking skills. You may be asked to explain what you think of the given situation or your first reaction after looking at the given image. You are required to solve any random problem, and then you have to explain to the recruiter about your thought processes. The interviewer here is more focused on the way you reach the conclusion rather than the conclusion itself. Your thought process helps the interviewer to analyse and evaluate the way you approach various problems

15. Critical Thinking While Driving

Imagine you are driving on a busy road and your phone starts ringing. It’s an urgent call that you have to pick. What would you do? Would you pick up the call and risk yourself into an accident or stop your car on the roadside to take the call. Critical thinking helps you to make accurate decisions while driving, it includes finding the right place to park your car, analysing whether you can pass the car through that narrow street or not, or how to handle if any animal suddenly comes in front of your car. Hence, critical thinking is must require skill in driving.

16. Critical Thinking in Business

Critical thinking is one of the most important things that the owner of the business needs to possess. One has to make several important decisions, effectively communicate with the clients, hire suitable employees, take certain risks, and deal with several ups and downs in the business, and much more; all these things require critical thinking.

7 Ways You Can Engage Critical Thinking in Everyday Life

Critical thinking is an essential skill that everyone needs to develop in order to make meaningful and informed decisions. It is an important part of problem-solving, decision-making, and creative thinking in professional lives as well as personal. It involves taking a step back from a problem or situation, looking at it from different perspectives, and assessing the various solutions or outcomes that can arise.

This blog post will examine what critical thinking skills are and their importance, as well as provide tips for developing this important soft skill.

Table of Contents

What is Critical Thinking?

Critical thinking is a process of analyzing and evaluating information, making judgments and drawing conclusions based on the analysis. It involves looking at a subject from various angles and being able to acquire new perspectives from different sources. This process also involves being able to evaluate the credibility of the source, weighing different options and being able to identify the most effective solutions.

Critical thinkers think more effectively, make better decisions and tackle complex problems with greater confidence. It is a vital skill for anyone who wishes to be successful in the workplace and lead a peaceful personal life too.

Critical Thinking Examples

Analytical thinking.

Analytical thinking is a type of critical thinking that involves breaking down complex information into smaller parts in order to better understand it. It involves looking at the facts and data, analyzing them, and then drawing conclusions based on deductive reasoning.

Analytical skills require one to be able to identify patterns and trends in the data, as well as being able to draw logical conclusions from the evidence. This type of critical thinking can be applied to any situation, from everyday life to complex business decisions.

Creative Thinking

Creative thinking is a form of critical thinking that involves coming up with new and innovative ideas. It is the process of generating ideas, solutions, or products that are unique and original.

Creative thinkers, especially neurodivergent employees , adopt a “think outside the box” approach and come up with creative solutions to problems. This type of thinking encourages individuals to explore different possibilities and look at things from different perspectives.

Scientific Thinking

Scientific thinking is a form of critical thinking that involves using the scientific method to analyze and evaluate data. This type of thinking involves gathering evidence, forming hypotheses, testing those hypotheses, and drawing conclusions based on the results. Scientific thinking requires an open mind and an ability to look at a problem from multiple angles in order to come up with the best solution.

Contrary to popular belief, pioneers of scientific thinking do not prescribe to science as what is “known as fact”, but that the goal of science is to disprove what has come before.

Open-Mindedness

Open-mindedness is an important part of critical thinking. It involves being able to consider different perspectives and ideas without bias or prejudice. Open-mindedness encourages individuals to be more receptive to new ideas, challenge their own beliefs and assumptions, and think outside the box.

Open-mindedness also allows for a greater understanding of other people’s personalities , which can lead to better relationships with the wider world. It’s important to note everyone has cognitive biases.

But with open-mindedness, one can use open-mindedness and reflective thinking to overcome these cognitive biases in the interests of the world around them, if not their own belief system.

Asking The Right Questions

Asking the right questions is an important part of critical thinking. It involves being able to identify the key elements of a problem or situation and then asking questions that will help you gain more information about it.

Asking the right questions can help you spot connections between ideas, better understand a situation, identify potential solutions, and make informed decisions. Critical thinking examples of questions that can be asked include: What are the facts? What assumptions are being made, or could be made?

Critical thinking is pivotal to success in any leadership role

Divergent Thinking vs. Critical Thinking

There is a slight difference. Divergent thinking is the process of generating multiple solutions to a problem, while critical thinking is the process of evaluating those solutions.

Divergent thinking encourages individuals to explore different possibilities and come up with creative ideas. Critical thinking helps them evaluate those solutions and determine which one is best.

In conclusion, engaging in critical thinking can help you make better decisions in everyday life. It involves being able to identify patterns and connections between ideas, ask the right questions, and evaluate potential solutions.

It also requires an open mind and the ability to think outside the box. By engaging in critical thinking on a regular basis, you become more aware of your own biases and assumptions, as well as those of others.

The Seven Steps of Critical Thinking

The concept of critical thinking can be difficult to grasp, but it is a vital skill to have. Critical thinking skills allow you to look objectively at a situation and use evidence, facts, and analysis to form a judgement. It involves the ability to recognize and assess assumptions, evaluate arguments, and draw accurate conclusions .

Here are the seven steps of critical thinking:

1. Defining the Problem With Different Types of Thinking

One of the first steps in critical thinking is to define the problem that needs to be solved. Without a clear understanding of the problem, it will be difficult to develop a plan to solve it. This step involves gathering all the available information about the problem, researching the issue, and understanding the scope of the problem.

This can include examining the root causes, the implications of the problem, and any potential solutions. Defining the problem allows you to frame the problem in a way that makes it easier to evaluate and identify potential solutions.

2. Gathering Relevant Information by Active Listening

Gathering relevant information is an important part of critical thinking. This involves learning as much as possible about the subject we are thinking about by researching, reading, and asking questions.

It is important to make sure that the information we are gathering is accurate and up-to-date, and that we are looking at the issue from multiple perspectives. Gathering the right information can help us form more accurate conclusions and can help us make better decisions with an improved form of knowledge.

3. Analyzing the Information

Analyzing the information is one of the most important elements of critical thinking. This involves breaking the information down into different parts and evaluating each individual component. By assessing the facts, data, and other information, you can begin to identify patterns and make connections between the different pieces of information.

This helps you to draw conclusions that are based on evidence and logic, as opposed to assumptions or personal bias. It also allows you to develop a more comprehensive view of the issue so that you can make well-informed decisions.

4. Developing Real Life Solutions

Developing solutions is the fourth step in critical thinking. This involves taking the information you have gathered and analyzing it to find potential solutions to the problem. During this step, you should consider all the facts, as well as other potential solutions that may not have been considered.

You should also evaluate the potential effects of each solution and its implications for the problem. This step allows you to differentiate between good and bad solutions and make a decision on which is best for the situation.

5. Evaluating Solutions Using Existing Knowledge

The next stage of the critical thinking process is evaluating solutions. This is the point where you assess the effectiveness, feasibility, and plausibility of each solution. You will need to consider the implications of each solution, the costs and benefits associated with it, and the expected outcomes.

This step often requires you to weigh the pros and cons of each solution and determine which one is best. Finally, you can decide whether the proposed solution is viable or if it needs to be modified or scrapped.

6. Making a Decision Using Valid Reasoning

Making a decision is the penultimate step in the critical thinking process. This is the culmination of all the research and analysis that has been done up to this point. A decision must be made based on the available evidence and the facts.

Once a decision has been made, it is important to evaluate the outcome and reflect on the decision-making process. This provides an opportunity to learn from the experience and improve decision-making skills in the future.

7. Reflecting on the Decision Made Through Observational Ability

Critical thinking skills also include reflecting on the decision made once it has been made. It is important to take the time to assess the decision. That way, you can determine if it is the best solution based on the available data and the desired outcomes. Reflecting on decisions can help identify potential opportunities, or areas for improvement, through learning from mistakes in reasoning and personal biases.

By reflecting on decisions, it is possible to gain a better understanding of the situation and identify potential areas for improvement. This can help identify potential mistakes and learn from them.

Additionally, reflecting on the decision can help to develop a deeper understanding of the decision-making process and the associated risks and benefits that come with exercising such a valuable skill.

Anyone Can Be a Critical Thinker

In conclusion, critical thinking skills are invaluable in any field or situation. They require a disciplined process of observation, analysis, synthesis, and evaluation of information, and help individuals to identify and solve problems and make well-informed decisions.

Developing and honing your critical thinking ability can help you confidently develop creative solutions and make better decisions, in both professional and personal settings.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Table of contents

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Examples of Critical Thinking in Everyday

Most people think of high academia when they hear the phrase “critical thinking.” They have a natural tendency to associate it with higher learning. While that may be true, it may surprise people to know that everyone uses critical thinking skills every day.

Critical thinking is defined as looking at an issue objectively, gathering information, analyzing it, and then forming a judgment about it. It is void of emotionally-responsive decision making but takes an analytical approach. People unknowingly participate in examples of critical thinking in everyday life. 

Critical Thinking On the Job

Employers love those who have critical thinking skills and will promote those employees to management. The key plus here is those who can use these skills can solve problems that are bound to occur in a workplace daily.

For instance, someone with critical thinking skills is going to be able to put together an effective team for a project and be able to manage the team. They can understand all team members’ talents and contributions while inputting their own.

Critical thinkers don’t jump to conclusions when a problem arises but gathers information to make an informed decision. They can see the situation as someone else sees it. This is invaluable when dealing with employees.

Another aspect of critical thinking skills on the job is those with this ability manage their time wisely. They know how to prioritize duties and can judge the rate of success return on time spent on various tasks, so they spend more time on those things with a high return rate.

Specific Examples Demonstrating Critical Thinking

Examples of critical thinking in everyday life abounds in all parts of life. A triage nurse will use it to prioritize patients for treatment and a plumber uses it when he decides what materials he needs to complete a job

A store manager uses it after he gets customers’ feedback to make changes in his shop and an attorney uses it to create a winning courtroom strategy.

Critical Thinking in Your Personal Life

Everyone uses critical thinking at some point. Small business owners need it to figure out how to increase costs, keep employees happy or reduce costs and a soccer coach uses it to create a tactic to maximize his team’s strengths and minimize weaknesses.

However, some of the most useful ways all of us use critical thinking is with others in our lives. That includes our families, our friends, and our co-workers.

One perfect example is when a spouse comes home after a hard day at work. Someone with critical thinking skills immediately assesses the situation to see how they can help. They stand back for a few moments to gather information, to hear what their spouse has to say.

Then, they may suggest a solution to the problem or even propose the two of them do something fun to take their minds off it. The suggestions rely solely on the fact-gathering and knowledge of their spouse’s personality and a judgment of the situation. That is critical thinking.

Parents are some of the best critical thinkers on the planet because they have to access their children’s behavior and make judgments on how to handle it all day long, every day. The process is the same as any other in the critical thinking spectrum.

They ask open-ended questions, get information, make a judgment, and offer insight. This happens in households multiple times a day.

What All Does Critical Thinking Involve?

Critical thinking happens quickly for most people so it can be difficult to break down into segments. However, six aspects of it are important.

Gathering information

Critical thinkers wait until they have more information before creating a judgment. They know how to obtain the necessary information.

Communication skills

Those gathering information know how to communicate to get it. They are good at this process and ask open-ended questions to allow others to express themselves freely.

Thinking creatively

This is one of the most important aspects of critical thinking. It can be called “thinking outside the box” but it’s a recognition that some solutions aren’t right in front of you. There are times you have to go beyond the normal policies and procedures to achieve a positive result.

This is especially true in areas of customer service, medicine, the law, and even in professional services such as wedding coordinating.

Being open-minded

This aspect is important to critical thinking because it means you are listening to others’ opinions and information rather than relying solely on your own. You can look to others and know there can be more than one solution.

Problem-solving skills

This trait appears toward the end of the critical thinking process. You make a judgment and come to a solution after evaluating everything. It is the ability to solve a problem with the resources you have by creatively reassigning them or using them in some other way.

Can Children Learn Critical Thinking?

Children need to develop critical thinking habits early as it helps them grow into strong leaders. Parents can help their children learn these habits by encouraging reading of diverse materials, and helping them back up their ideas with evidence.

Parents who encourage learning and allow children to debate them on some subjects will find their child is more confident in their critical learning skills. This is how they practice analytically expressing their thoughts.

One important aspect of teaching children critical thinking skills is to guide them through making decisions instead of making all decisions for them. They gain confidence in their abilities this way.

Critical thinking skills are a higher level of learning but it is something that is accessible to everyone of all types of intelligence. Critical thinking was probably one of the primary contributors to the survival of the human species.

People should realize how valuable it is with these examples of critical thinking in everyday life, and work to pass on these same skills to their children. That way, they won’t have to learn them through trial and error as many people do and will have a leg up on leadership qualities for the future.

Intriguing Examples of Critical Thinking in Everyday Life

• Self-improvement

When it comes to confronting life’s everyday problems – a challenging project at work, a relationship issue, the inevitable decay of our bodies – most of us follow a standard operating procedure. We stare at the issue for a couple of minutes. Then, once we’re confident that we know what the problem is all about – and a lot of times even before that – we take action.

We’d like to think that we are virtuous decision-makers. That when an issue occurs, we examine it carefully like doctors using sophisticated testing methods.

In reality, we are heavily influenced by our biases and we rely on our gut feeling. Both of these, however, inflict heavy damage on our current reality and future state.

Plainly, if we don’t take some time to consider the consequences of our instinctive behavior, we often make stupid decisions that we regret and have a negative influence on our lives.

And while we can do better. It’s not an error-free process.

When the first part of the problem-solving phase goes too far, yes it can lead to good thinking , but it can also lead to overthinking.

To get better. To improve the first part and decrease the second, we need this: critical thinking strategies .

Critical thinking is like taking a piece of information, putting it inside a tube, and heading toward a laboratory. There, you look at it using a microscope. You test it against different substances. You write a detailed report about all reactions. Then, finally, after discussing the case with the council members of the lab, you decide how to proceed.

It’s an elaborate process that takes time, but it tends to require less when we gain experience.

When I first read about critical thinking. 1 I thought that, by using what I’ve learned, I’ll now “win” 100% of all problems I encounter.

Sadly, this wasn’t the case.

It’s tempting to think that battling everyday challenges is based on a straight-line process. That is, when you have a problem, you turn off your biases, you apply logic, you fact-check, you ask experts in the field, and then – only then – you move forward.

A lot of times, even if we consider ourselves owners of a competent brain – we know what are the main critical thinking barriers and what are the 7 critical thinking skills . We still do things even a child won’t do.

Handling daily obstacles is more like finding your way in a maze. There are a lot of uncertainties around what path to take and what the exit should look like.

Besides engaging in provoking critical thinking questions . I find it equally valuable – if not even more – to learn about real-life examples of critical thinking in everyday life.

Here’s why:

How Is Critical thinking Used In Everyday Life?

Critical thinking in everyday life happens by building a case library. You continuously observe what happens to you. You store the info. And then, when needed, you pull fragments out to aid you when you are facing a similar situation in the future.

Before we get to the case library term. Let’s discuss something else first…

In the book Accelerated Expertise , the authors talk about an interesting concept. It’s called ill-structured problems. I know, wicked!

The premise of the theory is that “ill-structured problems are characterized by their lack of a clear path to a solution.” 2

The elements of the problems are highly variable. Making it really hard to navigate around the foggy terrain towards an appropriate solution.

Just to give you an example to “see” what I’m talking about…

A well-structured activity is steering a car. The objectives are pretty straightforward in terms of how to successfully drive around town. You need to do a handful of things inside the car to do well – steer the car, shift gears, use the break – and only one thing outside the car – monitor carefully what’s happening around you.

Conversely, an ill-structured problem in relation to cars is designing a car. There is no manual on how to design not only a nice-looking car. But also one that is safe, comfortable – and in order to sell well – appreciated by the masses.

What does this remind you of?

That’s right: life.

There is a reason people become emotionally unstable, divorce, use illegal substances, go bankrupt – i.e., do stupid stuff.

The issues we need to handle daily are ill.

We commonly don’t have enough information when deciding on something, experience to deal with unknowns, or simply feel crushed by social pressure. Plus, of course, the ultimate reasons: we follow our emotions, we are guided by our ego, and we let our biases steer us. 3

Fortunately, we can enable critical thinking. The thinking type that can grant us the ability to reuse knowledge from one field and adapt it to a totally different concept.

And while that sounds good in theory. It’s incredibly hard in real life.

The Challenge of Using Critical Thinking in Real Life

We all know what are the main thinking strategies that can drastically improve our decision-making process. I mean, we all have internet access and we can all browse through various educational sites that promise to reform the way we think for the better.

But the interesting question here is – are you certain you are practicing the practical information you so enthusiastically consume?

Simple as it sounds, it’s a constructively difficult question to answer.

You could have read Thinking in Systems by Donella H. Meadows but this doesn’t mean that you are actually using systems thinking in your daily life .

You could have read Atomic Habits by James Clear but this doesn’t mean that you are able to change your bad habits with good ones .

The main blockers that prevent us from using the information we consume are commonly two: lack of time and lack of understanding of the material.

But there is one more.

Continuously staying in your comfort zone and never trying something new.

In other words, we learn best not by reading the best books. But by taking action; trying new and different things; and engaging in challenges.

Challenges help us test the knowledge we gathered along the way and allow us to create a case library of tough cases.

For instance, if you work as an events coordinator, a project manager, or you are a team lead. Eventually, you become good at organizing stuff. This will most probably mean that you can organize weddings – say, your wedding. The skills you’ve gathered during your day job can definitely be applied to organizing a personal event.

However, you can’t completely copy-paste what you do on your job because your spouse is not as patient with you as your co-workers.

But what you can do, is take part of the skills you’ve amassed during your job and mix them with the knowledge you have about your spouse. This cocktail of insights will help you plan the event without ruining the event.

For instance, instead of giving orders to your wife/husband while you are planning – as you normally give orders at work. You consider his/hers feelings, and common ways he/she responds to certain situations. All of this is done to ensure that there will be an actual wedding to plan.

And how do you know what your spouse likes/dislikes and wants/doesn’t want?

That’s right, you’ve built up a library of cases in your head about his/her likes or dislikes.

If you haven’t, chances are that you’ll soon have to search for another partner.

After all, who will stay with a person if he/she doesn’t know what his/her partner’s favorite flower, meal, movie, book, interest, etcetera is?

That’s why cases are more important than concepts.

And how do you create a case library?

By experience. The more you go outside of your comfort zon e. The more elaborate your worldview becomes.

Basically, it’s one thing to watch videos about, say, creating a wooden chair. It’s quite another thing to make one yourself.

When you live with someone long enough, you eventually figure out what are his/hers likes and dislikes.

This same process happens when you start a new job in a new field. You become good at doing the job after years not only because time passes. But also because the more time you work a specific job, the more problems you encounter. Thus, you learn how to solve these different problems and how to react in an unexpected situation.

To draw a conclusion.

Time is not the key thing for mastering a field. Sure it does help to become proficient. But it’s not a prerequisite for success.

What you really need is to consistently position yourself against tough problems.

The faster you encounter difficult cases. The faster you’ll improve.

But there is another issue in relation to this. Problems and hard-to-handle situations are not that frequent. They are not evenly distributed.

Two people starting the same position today can have a totally different year – person A can have a smooth year, while person B can face problem after problem. In this case, at the end of the year, person B is much more qualified than person A.

To bring back the analogy with the partner. In time you’ll learn her/his likes and dislikes. But a better strategy (probably) will be to have an honest conversation so you can speed up the info-gathering phase.

How We Can Apply Critical Thinking In Our Everyday Life?

With the below examples, my aim is to present how a person applying critical thinking can successfully navigate around the daily hurdles we all normally have to handle.

The more cases you explore. The better you’ll be at reasoning and thinking in general.

While some scenes might not seem difficult per se. I’m sure that if you remember them and apply them when similar issues actually occur in the future, you’ll react much better to a problem:

Fifteen Examples of Critical Thinking in Everyday Life:

• A person who consciously throws out all junk food when starting a diet to channel his willpower toward exercising rather than thinking about delicious snacks.
• The same person who’s on a diet does not enter the restaurant when he’s staying at a hotel with an all-inclusive buffet. Instead, he asks his partner/friend to pick a salad for him.
• A person uninstalling the social media app from his phone and unfollowing everyone online to prevent social media from consuming most of his time daily.
• A person placing educational materials in the center of his living room to help his child learn stuff instead of playing all day.
• A person scheduling emails to go to his friends to ensure that he’ll keep in touch with them even when he’s busy at work.
• A person carrying a book with him so he can read when he’s waiting in line – instead of drowning in status updates from people he doesn’t know.
• A person who records his achievements – creates a library of good feedback – which he can browse when failures eventually reach him.
• A person who keeps an idea journal where he’s recording ideas and random thoughts because he knows that a) he will need them at some point; b) we forget things ultra fast .
• A person comparing himself not with the most productive person on the planet or the richest guy in Hollywood but rather with himself yesterday. This person knows that judging your work output and your money management skills against who you were a year ago and/or a day ago feels more uplifting than the alternative.
• A person who is scheduling – and protecting – time daily to learn and study new things because he’s well aware that the world is constantly advancing and you can stay ahead only if you are continuously learning yourself.
• A person who is not focusing on goals – losing 15 pounds. Rather, focusing on systems – being a healthy person.
• A person fully aware that he can’t achieve everything and he can’t please everyone. Therefore, he focuses on being good at one main thing while maintaining a tight circle of friends.
• A person who not only plans for the worse. But also makes room for the terrible because he knows that the future is always entirely uncertain – and unpredictable.
• A person who pauses before responding when verbally attacked. Since he knows that emotions can be a bad advisor, he waits for them to be displaced by logic and reason.
• A person who is doing the work even when he doesn’t feel like working. He knows that’s the main difference between amateurs and professionals – amateurs stop even when there is a tiny obstacle whereas professionals understand that obstacles are part of the process of becoming great.

Some Closing Thoughts

Did you spot the similarities in all of the cases above?

Don’t worry. Take your time. I’ll wait…

So, we can gently summarize what all cases above have in common with one word: patience.

We can practically continue forever by sharing critical thinking examples in real life. But that’s not the point.

The idea is to see the essential ingredient for good thinking.

That is, you don’t respond immediately to a situation. You postpone the instantaneous reaction that comes to your mind, delay the gratification , and wait for logic and reason to arrive at the scene.

You are not annoyed, irritated, or afraid when facing problems.

Like a Buddhist monk who meditated for days on top of a frozen mountain. You wait patiently for the best opportunity and the optimal solution to a situation.

I hope that the examples of critical thinking above not only inspired you to stay still, and arouse your curiosity but also showed you what is possible when we apply thinking before acting.

Thinking About Kahneman’s Contribution to Critical Thinking

A nobel laureate on contributions on the importance of 'thinking slow.'.

Updated April 10, 2024 | Reviewed by Lybi Ma

• Kahneman won a Nobel Memorial Prize in Economics for his work.
• He found that people are often irrational about economics.

During my Ph.D. studies, I recall focusing on reconceptualising what we know of as critical thinking to include reflective judgment (not jumping to conclusions and taking your time in your decision-making to consider the nature limits, and certainty of knowing) on par with the commonly accepted skills and dispositions components. The importance of reflective judgment wasn’t a particularly novel idea – a good deal of research on reflective judgment and similar processes akin to critical thinking had already been conducted (see King and Kitchener, 1994; Kuhn, 1999; 2000; Stanovich, 1999). However, reflective judgment – as opposed to intuitive judgment – didn’t seem to have ‘the presence’ in the discussion of critical thinking that it does today.

The same month I submitted my Ph.D. back in 2011, a book was released that massively helped to accomplish what I had been working to help facilitate – changing the terrain of thought surrounding critical thinking: Thinking, Fast, and Slow . Its author, Daniel Kahneman, passed away a couple of weeks ago at age 90. Psychology students will likely recognise the name associated with Amos Tversky and their classic work together in the 1970s on the availability, representativeness, and anchoring and adjustment heuristics (for example, Tversky and Kahneman, 1974). Indeed, such heuristics, alongside the affect heuristic (Kahneman and Frederick, 2002; Slovic and colleagues, 2002) play a large role in how we think about thinking and barriers to critical thought. In 2002, Kahneman won a Nobel Memorial Prize in Economics for his work on prospect theory concerning loss aversion and people’s often irrational approach to economics. Indeed, Kahneman’s resume is full of awards and achievements.

However, the accomplishment I will remember him best for is the publication of Thinking, Fast, and Slow and its contribution to the field of critical thinking. Funny enough, I don’t recall the term, critical thinking being used very often in the book, if at all – and I read it two or three times. No, critical thinking was not the focus of his book; rather system 1 (fast) and 2 (slow) thinking (see also Stanovich, 1999) – intuitive and reflective judgment. Not only did this book put into the spotlight many of the mechanics of reflective judgment for fellow academics and researchers of cognitive psychology, it also did so l for non-academic audiences – becoming a New York Times bestseller. Moreover, it won the Los Angeles Times Book Award for Current Interest, and the National Academy of Sciences Communication Award for Best Book (both in 2011). Good thinking was cool again in popular culture.

In the critical thinking literature, reflective judgment – regardless of what you want to call it (for example, system 2 thinking, epistemological understanding, ‘taking your time’) – is becoming more accepted as a core component of critical thinking. The field of critical thinking research and psychology more broadly, owes Kahneman a debt of gratitude for his contributions in helping shine a light on the importance of ‘thinking slow’. Thank you .

Critical Thinking: A Model of Intelligence for Solving Real-World Problems

Most theories of intelligence do not directly address the question of whether people with high intelligence can successfully solve real world problems. A high IQ is correlated with many important outcomes (e.g., academic prominence, reduced crime), but it does not protect against cognitive biases, partisan thinking, reactance, or confirmation bias, among others. There are several newer theories that directly address the question about solving real-world problems. Prominent among them is Sternberg’s adaptive intelligence with “adaptation to the environment” as the central premise, a construct that does not exist on standardized IQ tests. Similarly, some scholars argue that standardized tests of intelligence are not measures of rational thought—the sort of skill/ability that would be needed to address complex real-world problems. Other investigators advocate for critical thinking as a model of intelligence specifically designed for addressing real-world problems. Yes, intelligence (i.e., critical thinking) can be enhanced and used for solving a real-world problem such as COVID-19, which we use as an example of contemporary problems that need a new approach.

1. Introduction

The editors of this Special Issue asked authors to respond to a deceptively simple statement: “How Intelligence Can Be a Solution to Consequential World Problems.” This statement holds many complexities, including how intelligence is defined and which theories are designed to address real-world problems.

2. The Problem with Using Standardized IQ Measures for Real-World Problems

For the most part, we identify high intelligence as having a high score on a standardized test of intelligence. Like any test score, IQ can only reflect what is on the given test. Most contemporary standardized measures of intelligence include vocabulary, working memory, spatial skills, analogies, processing speed, and puzzle-like elements (e.g., Wechsler Adult Intelligence Scale Fourth Edition; see ( Drozdick et al. 2012 )). Measures of IQ correlate with many important outcomes, including academic performance ( Kretzschmar et al. 2016 ), job-related skills ( Hunter and Schmidt 1996 ), reduced likelihood of criminal behavior ( Burhan et al. 2014 ), and for those with exceptionally high IQs, obtaining a doctorate and publishing scholarly articles ( McCabe et al. 2020 ). Gottfredson ( 1997, p. 81 ) summarized these effects when she said the “predictive validity of g is ubiquitous.” More recent research using longitudinal data, found that general mental abilities and specific abilities are good predictors of several work variables including job prestige, and income ( Lang and Kell 2020 ). Although assessments of IQ are useful in many contexts, having a high IQ does not protect against falling for common cognitive fallacies (e.g., blind spot bias, reactance, anecdotal reasoning), relying on biased and blatantly one-sided information sources, failing to consider information that does not conform to one’s preferred view of reality (confirmation bias), resisting pressure to think and act in a certain way, among others. This point was clearly articulated by Stanovich ( 2009, p. 3 ) when he stated that,” IQ tests measure only a small set of the thinking abilities that people need.”

3. Which Theories of Intelligence Are Relevant to the Question?

Most theories of intelligence do not directly address the question of whether people with high intelligence can successfully solve real world problems. For example, Grossmann et al. ( 2013 ) cite many studies in which IQ scores have not predicted well-being, including life satisfaction and longevity. Using a stratified random sample of Americans, these investigators found that wise reasoning is associated with life satisfaction, and that “there was no association between intelligence and well-being” (p. 944). (critical thinking [CT] is often referred to as “wise reasoning” or “rational thinking,”). Similar results were reported by Wirthwein and Rost ( 2011 ) who compared life satisfaction in several domains for gifted adults and adults of average intelligence. There were no differences in any of the measures of subjective well-being, except for leisure, which was significantly lower for the gifted adults. Additional research in a series of experiments by Stanovich and West ( 2008 ) found that participants with high cognitive ability were as likely as others to endorse positions that are consistent with their biases, and they were equally likely to prefer one-sided arguments over those that provided a balanced argument. There are several newer theories that directly address the question about solving real-world problems. Prominent among them is Sternberg’s adaptive intelligence with “adaptation to the environment” as the central premise, a construct that does not exist on standardized IQ tests (e.g., Sternberg 2019 ). Similarly, Stanovich and West ( 2014 ) argue that standardized tests of intelligence are not measures of rational thought—the sort of skill/ability that would be needed to address complex real-world problems. Halpern and Butler ( 2020 ) advocate for CT as a useful model of intelligence for addressing real-world problems because it was designed for this purpose. Although there is much overlap among these more recent theories, often using different terms for similar concepts, we use Halpern and Butler’s conceptualization to make our point: Yes, intelligence (i.e., CT) can be enhanced and used for solving a real-world problem like COVID-19.

4. Critical Thinking as an Applied Model for Intelligence

One definition of intelligence that directly addresses the question about intelligence and real-world problem solving comes from Nickerson ( 2020, p. 205 ): “the ability to learn, to reason well, to solve novel problems, and to deal effectively with novel problems—often unpredictable—that confront one in daily life.” Using this definition, the question of whether intelligent thinking can solve a world problem like the novel coronavirus is a resounding “yes” because solutions to real-world novel problems are part of his definition. This is a popular idea in the general public. For example, over 1000 business managers and hiring executives said that they want employees who can think critically based on the belief that CT skills will help them solve work-related problems ( Hart Research Associates 2018 ).

We define CT as the use of those cognitive skills or strategies that increase the probability of a desirable outcome. It is used to describe thinking that is purposeful, reasoned, and goal directed--the kind of thinking involved in solving problems, formulating inferences, calculating likelihoods, and making decisions, when the thinker is using skills that are thoughtful and effective for the particular context and type of thinking task. International surveys conducted by the OECD ( 2019, p. 16 ) established “key information-processing competencies” that are “highly transferable, in that they are relevant to many social contexts and work situations; and ‘learnable’ and therefore subject to the influence of policy.” One of these skills is problem solving, which is one subset of CT skills.

The CT model of intelligence is comprised of two components: (1) understanding information at a deep, meaningful level and (2) appropriate use of CT skills. The underlying idea is that CT skills can be identified, taught, and learned, and when they are recognized and applied in novel settings, the individual is demonstrating intelligent thought. CT skills include judging the credibility of an information source, making cost–benefit calculations, recognizing regression to the mean, understanding the limits of extrapolation, muting reactance responses, using analogical reasoning, rating the strength of reasons that support and fail to support a conclusion, and recognizing hindsight bias or confirmation bias, among others. Critical thinkers use these skills appropriately, without prompting, and usually with conscious intent in a variety of settings.

One of the key concepts in this model is that CT skills transfer in appropriate situations. Thus, assessments using situational judgments are needed to assess whether particular skills have transferred to a novel situation where it is appropriate. In an assessment created by the first author ( Halpern 2018 ), short paragraphs provide information about 20 different everyday scenarios (e.g., A speaker at the meeting of your local school board reported that when drug use rises, grades decline; so schools need to enforce a “war on drugs” to improve student grades); participants provide two response formats for every scenario: (a) constructed responses where they respond with short written responses, followed by (b) forced choice responses (e.g., multiple choice, rating or ranking of alternatives) for the same situations.

There is a large and growing empirical literature to support the assertion that CT skills can be learned and will transfer (when taught for transfer). See for example, Holmes et al. ( 2015 ), who wrote in the prestigious Proceedings of the National Academy of Sciences , that there was “significant and sustained improvement in students’ critical thinking behavior” (p. 11,199) for students who received CT instruction. Abrami et al. ( 2015, para. 1 ) concluded from a meta-analysis that “there are effective strategies for teaching CT skills, both generic and content specific, and CT dispositions, at all educational levels and across all disciplinary areas.” Abrami et al. ( 2008, para. 1 ), included 341 effect sizes in a meta-analysis. They wrote: “findings make it clear that improvement in students’ CT skills and dispositions cannot be a matter of implicit expectation.” A strong test of whether CT skills can be used for real-word problems comes from research by Butler et al. ( 2017 ). Community adults and college students (N = 244) completed several scales including an assessment of CT, an intelligence test, and an inventory of real-life events. Both CT scores and intelligence scores predicted individual outcomes on the inventory of real-life events, but CT was a stronger predictor.

Heijltjes et al. ( 2015, p. 487 ) randomly assigned participants to either a CT instruction group or one of six other control conditions. They found that “only participants assigned to CT instruction improved their reasoning skills.” Similarly, when Halpern et al. ( 2012 ) used random assignment of participants to either a learning group where they were taught scientific reasoning skills using a game format or a control condition (which also used computerized learning and was similar in length), participants in the scientific skills learning group showed higher proportional learning gains than students who did not play the game. As the body of additional supportive research is too large to report here, interested readers can find additional lists of CT skills and support for the assertion that these skills can be learned and will transfer in Halpern and Dunn ( Forthcoming ). There is a clear need for more high-quality research on the application and transfer of CT and its relationship to IQ.

5. Pandemics: COVID-19 as a Consequential Real-World Problem

A pandemic occurs when a disease runs rampant over an entire country or even the world. Pandemics have occurred throughout history: At the time of writing this article, COVID-19 is a world-wide pandemic whose actual death rate is unknown but estimated with projections of several million over the course of 2021 and beyond ( Mega 2020 ). Although vaccines are available, it will take some time to inoculate most or much of the world’s population. Since March 2020, national and international health agencies have created a list of actions that can slow and hopefully stop the spread of COVID (e.g., wearing face masks, practicing social distancing, avoiding group gatherings), yet many people in the United States and other countries have resisted their advice.

Could instruction in CT encourage more people to accept and comply with simple life-saving measures? There are many possible reasons to believe that by increasing citizens’ CT abilities, this problematic trend can be reversed for, at least, some unknown percentage of the population. We recognize the long history of social and cognitive research showing that changing attitudes and behaviors is difficult, and it would be unrealistic to expect that individuals with extreme beliefs supported by their social group and consistent with their political ideologies are likely to change. For example, an Iranian cleric and an orthodox rabbi both claimed (separately) that the COVID-19 vaccine can make people gay ( Marr 2021 ). These unfounded opinions are based on deeply held prejudicial beliefs that we expect to be resistant to CT. We are targeting those individuals who beliefs are less extreme and may be based on reasonable reservations, such as concern about the hasty development of the vaccine and the lack of long-term data on its effects. There should be some unknown proportion of individuals who can change their COVID-19-related beliefs and actions with appropriate instruction in CT. CT can be a (partial) antidote for the chaos of the modern world with armies of bots creating content on social media, political and other forces deliberately attempting to confuse issues, and almost all media labeled “fake news” by social influencers (i.e., people with followers that sometimes run to millions on various social media). Here, are some CT skills that could be helpful in getting more people to think more critically about pandemic-related issues.

Reasoning by Analogy and Judging the Credibility of the Source of Information

Early communications about the ability of masks to prevent the spread of COVID from national health agencies were not consistent. In many regions of the world, the benefits of wearing masks incited prolonged and acrimonious debates ( Tang 2020 ). However, after the initial confusion, virtually all of the global and national health organizations (e.g., WHO, National Health Service in the U. K., U. S. Centers for Disease Control and Prevention) endorse masks as a way to slow the spread of COVID ( Cheng et al. 2020 ; Chu et al. 2020 ). However, as we know, some people do not trust governmental agencies and often cite the conflicting information that was originally given as a reason for not wearing a mask. There are varied reasons for refusing to wear a mask, but the one most often cited is that it is against civil liberties ( Smith 2020 ). Reasoning by analogy is an appropriate CT skill for evaluating this belief (and a key skill in legal thinking). It might be useful to cite some of the many laws that already regulate our behavior such as, requiring health inspections for restaurants, setting speed limits, mandating seat belts when riding in a car, and establishing the age at which someone can consume alcohol. Individuals would be asked to consider how the mandate to wear a mask compares to these and other regulatory laws.

Another reason why some people resist the measures suggested by virtually every health agency concerns questions about whom to believe. Could training in CT change the beliefs and actions of even a small percentage of those opposed to wearing masks? Such training would include considering the following questions with practice across a wide domain of knowledge: (a) Does the source have sufficient expertise? (b) Is the expertise recent and relevant? (c) Is there a potential for gain by the information source, such as financial gain? (d) What would the ideal information source be and how close is the current source to the ideal? (e) Does the information source offer evidence that what they are recommending is likely to be correct? (f) Have you traced URLs to determine if the information in front of you really came from the alleged source?, etc. Of course, not everyone will respond in the same way to each question, so there is little likelihood that we would all think alike, but these questions provide a framework for evaluating credibility. Donovan et al. ( 2015 ) were successful using a similar approach to improve dynamic decision-making by asking participants to reflect on questions that relate to the decision. Imagine the effect of rigorous large-scale education in CT from elementary through secondary schools, as well as at the university-level. As stated above, empirical evidence has shown that people can become better thinkers with appropriate instruction in CT. With training, could we encourage some portion of the population to become more astute at judging the credibility of a source of information? It is an experiment worth trying.

6. Making Cost—Benefit Assessments for Actions That Would Slow the Spread of COVID-19

Historical records show that refusal to wear a mask during a pandemic is not a new reaction. The epidemic of 1918 also included mandates to wear masks, which drew public backlash. Then, as now, many people refused, even when they were told that it was a symbol of “wartime patriotism” because the 1918 pandemic occurred during World War I ( Lovelace 2020 ). CT instruction would include instruction in why and how to compute cost–benefit analyses. Estimates of “lives saved” by wearing a mask can be made meaningful with graphical displays that allow more people to understand large numbers. Gigerenzer ( 2020 ) found that people can understand risk ratios in medicine when the numbers are presented as frequencies instead of probabilities. If this information were used when presenting the likelihood of illness and death from COVID-19, could we increase the numbers of people who understand the severity of this disease? Small scale studies by Gigerenzer have shown that it is possible.

Analyzing Arguments to Determine Degree of Support for a Conclusion

The process of analyzing arguments requires that individuals rate the strength of support for and against a conclusion. By engaging in this practice, they must consider evidence and reasoning that may run counter to a preferred outcome. Kozyreva et al. ( 2020 ) call the deliberate failure to consider both supporting and conflicting data “deliberate ignorance”—avoiding or failing to consider information that could be useful in decision-making because it may collide with an existing belief. When applied to COVID-19, people would have to decide if the evidence for and against wearing a face mask is a reasonable way to stop the spread of this disease, and if they conclude that it is not, what are the costs and benefits of not wearing masks at a time when governmental health organizations are making them mandatory in public spaces? Again, we wonder if rigorous and systematic instruction in argument analysis would result in more positive attitudes and behaviors that relate to wearing a mask or other real-world problems. We believe that it is an experiment worth doing.

7. Conclusions

We believe that teaching CT is a worthwhile approach for educating the general public in order to improve reasoning and motivate actions to address, avert, or ameliorate real-world problems like the COVID-19 pandemic. Evidence suggests that CT can guide intelligent responses to societal and global problems. We are NOT claiming that CT skills will be a universal solution for the many real-world problems that we confront in contemporary society, or that everyone will substitute CT for other decision-making practices, but we do believe that systematic education in CT can help many people become better thinkers, and we believe that this is an important step toward creating a society that values and practices routine CT. The challenges are great, but the tools to tackle them are available, if we are willing to use them.

How Is Critical Thinking Used In Our Daily Lives?

Don’t jump on everything, don’t accept garbage, be skeptical. Skepticism is sometimes relevant depending on how you are able to tackle the issue, but what is critical thinking?

Believe it or not, critical thinking is used quite frequently in our daily lives: from deciding what to eat to choosing a new television show to watch, etc, the list is endless. We make use of this skill each time we make a decision, solve a problem, or interpret information, and that’s how the story goes.

What Is Critical Thinking?

At its very essence, critical thinking is the ability to reason logically and provide sound judgment on information relayed. It is a sensible technique for processing information and making decisions after a series of skeptical analyses.

It might interest you to know that this is one of the most sought-after skills employers look for in an applicant because it gives them an edge over different situations. Thinking critically helps you criticize information intelligently before arriving at a final judgment, in this case, it is almost impossible to get hoaxed.

Why Is Critical Thinking Important?

• Thinking critically helps you widen your horizon, as you delve deeper into the world of people and ideas.
• You can never be deceived because you get to see through the other party because of your interpersonal skills.
• Critical thinking can you reason logically on any topic or situation, from making a major life decision to choosing what to have for lunch.
• It can help you build a safer and toxic-free relationship.
• Critical thinking makes you happier.
• In a career, critical thinking helps improve your level of creativity, and innovation.

The necessity of critical thinking in our every day lives may not be immediately observed and appreciated, however, it is just there regardless. When planning a meal, or party, you’ll have to consider factors like budget, nutritional needs, personal preferences, and the availability of certain foods, and this is where critical thinking is needed the most.

Similarly, when choosing what to wear, we need to consider the weather, the occasion, and our personal style. Critical thinking allows us to weigh all of these factors and make the best decision for our individual needs and preferences.

The importance of critical thinking in these everyday decisions may not be immediately obvious, but it’s there nonetheless. So, how is critical thinking used in our everyday lives?

1. In Academics

The value of critical thinking in academics cannot be overemphasized because it is crucial for success. Students need to be able to analyze and evaluate information in order to learn new concepts and solve problems.

For example, when reading a text for a class, students need to be able to identify the author’s argument, assess the evidence provided, and evaluate whether the argument is valid.

In math and science, students need to be able to solve problems by breaking them down into smaller parts, identifying the relevant information, and using logic to find the solution. Critical thinking also helps students to form their own opinions and develop their own voices.

2. In Business

Critical thinking in business is a key skill that can help employees succeed. Business owners need to make decisions based on accurate and reliable information, and critical thinking is the process by which that information is analyzed and evaluated.

Critical thinking helps businesses to solve problems, identify opportunities, and make the best decisions for their future success.

For example, when making a decision about a new product, businesses need to use critical thinking to consider factors like market research, cost analysis, and competition. Without critical thinking, businesses would be at a disadvantage and would likely make poor decisions.

4. In Relationship

No relationship survives when both parties are not critical thinkers, because first of all when talking about an issue with a partner, critical thinking allows both parties to approach the situation calmly and rationally. It could also be an essential tool for effective communication and understanding.

5. In Judgment

Critical thinking is most needed when an individual wishes to make a judgment on an important issue. It helps people to identify their own biases and assumptions, listen to the other person’s perspective, and consider alternative solutions.

Critical thinking can also help to prevent arguments from turning into heated, emotionally charged discussions. Instead, it allows for constructive dialogue and a resolution that both partners can be satisfied with.

This encompasses every aspect of life, from career to family, to finances, the list is endless. Critical thinking is a necessity and can be a key to making better decisions, reaching goals, and achieving personal growth.

It helps people to take a step back from their biases and emotions and to focus on what’s most important in a given situation.

For example, when faced with a difficult situation, critical thinking can help a person assess the options, weigh the pros and cons, and make a decision that’s in their best interest. Critical thinking can also help people to learn from their experiences and to grow as individuals.
