Before you write your essay, it’s important to analyse the task and understand exactly what the essay question is asking. Your lecturer may give you some advice – pay attention to this as it will help you plan your answer.

Next conduct preliminary reading based on your lecture notes. At this stage, it’s not crucial to have a robust understanding of key theories or studies, but you should at least have a general “gist” of the literature.

After reading, plan a response to the task. This plan could be in the form of a mind map, a summary table, or by writing a core statement (which encompasses the entire argument of your essay in just a few sentences).

After writing your plan, conduct supplementary reading, refine your plan, and make it more detailed.

It is tempting to skip these preliminary steps and write the first draft while reading at the same time. However, reading and planning will make the essay writing process easier, quicker, and ensure a higher quality essay is produced.

Components of a Good Essay

Now, let us look at what constitutes a good essay in psychology. There are a number of important features.

• Global Structure – structure the material to allow for a logical sequence of ideas. Each paragraph / statement should follow sensibly from its predecessor. The essay should “flow”. The introduction, main body and conclusion should all be linked.
• Each paragraph should comprise a main theme, which is illustrated and developed through a number of points (supported by evidence).
• Knowledge and Understanding – recognize, recall, and show understanding of a range of scientific material that accurately reflects the main theoretical perspectives.
• Critical Evaluation – arguments should be supported by appropriate evidence and/or theory from the literature. Evidence of independent thinking, insight, and evaluation of the evidence.
• Quality of Written Communication – writing clearly and succinctly with appropriate use of paragraphs, spelling, and grammar. All sources are referenced accurately and in line with APA guidelines.

In the main body of the essay, every paragraph should demonstrate both knowledge and critical evaluation.

There should also be an appropriate balance between these two essay components. Try to aim for about a 60/40 split if possible.

Most students make the mistake of writing too much knowledge and not enough evaluation (which is the difficult bit).

It is best to structure your essay according to key themes. Themes are illustrated and developed through a number of points (supported by evidence).

Choose relevant points only, ones that most reveal the theme or help to make a convincing and interesting argument.

Knowledge and Understanding

Remember that an essay is simply a discussion / argument on paper. Don’t make the mistake of writing all the information you know regarding a particular topic.

You need to be concise, and clearly articulate your argument. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences.

Each paragraph should have a purpose / theme, and make a number of points – which need to be support by high quality evidence. Be clear why each point is is relevant to the argument. It would be useful at the beginning of each paragraph if you explicitly outlined the theme being discussed (.e.g. cognitive development, social development etc.).

Try not to overuse quotations in your essays. It is more appropriate to use original content to demonstrate your understanding.

Psychology is a science so you must support your ideas with evidence (not your own personal opinion). If you are discussing a theory or research study make sure you cite the source of the information.

Note this is not the author of a textbook you have read – but the original source / author(s) of the theory or research study.

For example:

Bowlby (1951) claimed that mothering is almost useless if delayed until after two and a half to three years and, for most children, if delayed till after 12 months, i.e. there is a critical period.

Maslow (1943) stated that people are motivated to achieve certain needs. When one need is fulfilled a person seeks to fullfil the next one, and so on.

As a general rule, make sure there is at least one citation (i.e. name of psychologist and date of publication) in each paragraph.

Remember to answer the essay question. Underline the keywords in the essay title. Don’t make the mistake of simply writing everything you know of a particular topic, be selective. Each paragraph in your essay should contribute to answering the essay question.

Critical Evaluation

In simple terms, this means outlining the strengths and limitations of a theory or research study.

There are many ways you can critically evaluate:

Methodological evaluation of research

Is the study valid / reliable ? Is the sample biased, or can we generalize the findings to other populations? What are the strengths and limitations of the method used and data obtained?

Be careful to ensure that any methodological criticisms are justified and not trite.

Rather than hunting for weaknesses in every study; only highlight limitations that make you doubt the conclusions that the authors have drawn – e.g., where an alternative explanation might be equally likely because something hasn’t been adequately controlled.

Compare or contrast different theories

Outline how the theories are similar and how they differ. This could be two (or more) theories of personality / memory / child development etc. Also try to communicate the value of the theory / study.

Debates or perspectives

Refer to debates such as nature or nurture, reductionism vs. holism, or the perspectives in psychology . For example, would they agree or disagree with a theory or the findings of the study?

What are the ethical issues of the research?

Does a study involve ethical issues such as deception, privacy, psychological or physical harm?

Gender bias

If research is biased towards men or women it does not provide a clear view of the behavior that has been studied. A dominantly male perspective is known as an androcentric bias.

Cultural bias

Is the theory / study ethnocentric? Psychology is predominantly a white, Euro-American enterprise. In some texts, over 90% of studies have US participants, who are predominantly white and middle class.

Does the theory or study being discussed judge other cultures by Western standards?

Animal Research

This raises the issue of whether it’s morally and/or scientifically right to use animals. The main criterion is that benefits must outweigh costs. But benefits are almost always to humans and costs to animals.

Animal research also raises the issue of extrapolation. Can we generalize from studies on animals to humans as their anatomy & physiology is different from humans?

The PEC System

It is very important to elaborate on your evaluation. Don’t just write a shopping list of brief (one or two sentence) evaluation points.

Instead, make sure you expand on your points, remember, quality of evaluation is most important than quantity.

When you are writing an evaluation paragraph, use the PEC system.

• Make your P oint.
• E xplain how and why the point is relevant.
• Discuss the C onsequences / implications of the theory or study. Are they positive or negative?

For Example

• Point: It is argued that psychoanalytic therapy is only of benefit to an articulate, intelligent, affluent minority.
• Explain: Because psychoanalytic therapy involves talking and gaining insight, and is costly and time-consuming, it is argued that it is only of benefit to an articulate, intelligent, affluent minority. Evidence suggests psychoanalytic therapy works best if the client is motivated and has a positive attitude.
• Consequences: A depressed client’s apathy, flat emotional state, and lack of motivation limit the appropriateness of psychoanalytic therapy for depression.

Furthermore, the levels of dependency of depressed clients mean that transference is more likely to develop.

Using Research Studies in your Essays

Research studies can either be knowledge or evaluation.

• If you refer to the procedures and findings of a study, this shows knowledge and understanding.
• If you comment on what the studies shows, and what it supports and challenges about the theory in question, this shows evaluation.

Writing an Introduction

It is often best to write your introduction when you have finished the main body of the essay, so that you have a good understanding of the topic area.

If there is a word count for your essay try to devote 10% of this to your introduction.

Ideally, the introduction should;

Identify the subject of the essay and define the key terms. Highlight the major issues which “lie behind” the question. Let the reader know how you will focus your essay by identifying the main themes to be discussed. “Signpost” the essay’s key argument, (and, if possible, how this argument is structured).

Introductions are very important as first impressions count and they can create a h alo effect in the mind of the lecturer grading your essay. If you start off well then you are more likely to be forgiven for the odd mistake later one.

Writing a Conclusion

So many students either forget to write a conclusion or fail to give it the attention it deserves.

If there is a word count for your essay try to devote 10% of this to your conclusion.

Ideally the conclusion should summarize the key themes / arguments of your essay. State the take home message – don’t sit on the fence, instead weigh up the evidence presented in the essay and make a decision which side of the argument has more support.

Also, you might like to suggest what future research may need to be conducted and why (read the discussion section of journal articles for this).

Don”t include new information / arguments (only information discussed in the main body of the essay).

If you are unsure of what to write read the essay question and answer it in one paragraph.

Points that unite or embrace several themes can be used to great effect as part of your conclusion.

The Importance of Flow

Obviously, what you write is important, but how you communicate your ideas / arguments has a significant influence on your overall grade. Most students may have similar information / content in their essays, but the better students communicate this information concisely and articulately.

When you have finished the first draft of your essay you must check if it “flows”. This is an important feature of quality of communication (along with spelling and grammar).

This means that the paragraphs follow a logical order (like the chapters in a novel). Have a global structure with themes arranged in a way that allows for a logical sequence of ideas. You might want to rearrange (cut and paste) paragraphs to a different position in your essay if they don”t appear to fit in with the essay structure.

To improve the flow of your essay make sure the last sentence of one paragraph links to first sentence of the next paragraph. This will help the essay flow and make it easier to read.

Finally, only repeat citations when it is unclear which study / theory you are discussing. Repeating citations unnecessarily disrupts the flow of an essay.

Referencing

The reference section is the list of all the sources cited in the essay (in alphabetical order). It is not a bibliography (a list of the books you used).

In simple terms every time you cite/refer to a name (and date) of a psychologist you need to reference the original source of the information.

If you have been using textbooks this is easy as the references are usually at the back of the book and you can just copy them down. If you have been using websites, then you may have a problem as they might not provide a reference section for you to copy.

References need to be set out APA style :

Author, A. A. (year). Title of work . Location: Publisher.

Journal Articles

Author, A. A., Author, B. B., & Author, C. C. (year). Article title. Journal Title, volume number (issue number), page numbers

A simple way to write your reference section is use Google scholar . Just type the name and date of the psychologist in the search box and click on the “cite” link.

Next, copy and paste the APA reference into the reference section of your essay.

Once again, remember that references need to be in alphabetical order according to surname.

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.

On Critical Thinking

Several years ago some teaching colleagues were talking about the real value of teaching psychology students to think critically. After some heated discussion, the last word was had by a colleague from North Carolina. “The real value of being a good critical thinker in psychology is so you won’t be a jerk,” he said with a smile. That observation remains one of my favorites in justifying why teaching critical thinking skills should be an important goal in psychology. However, I believe it captures only a fraction of the real value of teaching students to think critically about behavior.

What I s Critical Thinking?

Although there is little agreement about what it means to think critically in psychology, I like the following broad definition: The propensity and skills to engage in activity with reflec tive skepticism focused on deciding what to believe or do

Students often arrive at their first introductory course with what they believe is a thorough grasp of how life works. After all, they have been alive for at least 18 years, have witnessed their fair shares of crisis, joy, and tragedy, and have successfully navigated their way in to your classroom.

These students have had a lot of time to develop their own personal theories about how the world works and most are quite satisfied with the results. They often pride themselves on how good they are with people as well as how astute they are in understanding and explaining the motives of others. And they think they know what psychology is. Many are surprised- and sometimes disappointed- to discover that psychology is a science, and the rigor of psychological research is a shock. The breadth and depth of psychology feel daunting. Regardless of their sophistication in the discipline, students often are armed with a single strategy to survive the experience: Memorize the book and hope it works out on the exam. In many cases, this strategy will serve them well. Unfortunately, student exposure to critical thinking skill development may be more accidental than planful on the part of most teachers. Collaboration in my department and with other colleagues over the years has persuaded me that we need to approach critical thinking skills in a purposeful, systematic, and developmental manner from the introductory course through the capstone experience, propose that we need to teach critical thinking skills in three domains of psychology: practical (the “jerk avoidance” function), theoretical (developing scientific explanations for behavior), and methodological (testing scientific ideas). I will explore each of these areas and then offer some general suggestions about how psychology teachers can improve their purposeful pursuit of critical thinking objectives.

Practical Domain

Practical critical thinking is often expressed as a long-term, implicit goal of teachers of psychology, even though they may not spend much academic time teaching how to transfer critical thinking skills to make students wise consumers, more careful judges of character, or more cautious interpreters of behavior. Accurate appraisal of behavior is essential, yet few teachers invest time in helping students understand how vulnerable their own interpretations are to error.

Encourage practice in accurate description and interpretation of behavior by presenting students with ambiguous behavior samples. Ask them to distinguish what they observe (What is the behavior?) from the inferences they draw from the behavior (What is the meaning of the behavior?). I have found that cartoons, such as Simon Bond’s Uns p eakable Acts, can be a good resource for refining observation skills. Students quickly recognize that crisp behavioral descriptions are typically consistent from observer to observer, but inferences vary wildly. They recognize that their interpretations are highly personal and sometimes biased by their own values and preferences. As a result of experiencing such strong individual differences in interpretation, students may learn to be appropriately less confident of their immediate conclusions, more tolerant of ambiguity, and more likely to propose alternative explanations. As they acquire a good understanding of scientific procedures, effective control techniques, and legitimate forms of evidence, they may be less likely to fall victim to the multitude of off-base claims about behavior that confront us all. (How many Elvis sightings can be valid in one year?)

Theoretical Domain

Theoretical critical thinking involves helping the student develop an appreciation for scientific explanations of behavior. This means learning not just the content of psychology but how and why psychology is organized into concepts, principles, laws, and theories. Developing theoretical skills begins in the introductory course where the primary critical thinking objective is understanding and applying concepts appropriately. For example, when you introduce students to the principles of reinforcement, you can ask them to find examples of the principles in the news or to make up stories that illustrate the principles.

Mid-level courses in the major require more sophistication, moving students beyond application of concepts and principles to learning and applying theories. For instance, you can provide a rich case study in abnormal psychology and ask students to make sense of the case from different perspectives, emphasizing theoretical flexibility or accurate use of existing and accepted frameworks in psychology to explain patterns of behavior. In advanced courses we can justifiably ask students to evaluate theory, selecting the most useful or rejecting the least helpful. For example, students can contrast different models to explain drug addiction in physiological psychology. By examining the strengths and weaknesses of existing frameworks, they can select which theories serve best as they learn to justify their criticisms based on evidence and reason.

Capstone, honors, and graduate courses go beyond theory evaluation to encourage students to create theory. Students select a complex question about behavior (for example, identifying mechanisms that underlie autism or language acquisition) and develop their own theory-based explanations for the behavior. This challenge requires them to synthesize and integrate existing theory as well as devise new insights into the behavior.

Methodological Domain

Most departments offer many opportunities for students to develop their methodological critical thinking abilities by applying different research methods in psychology. Beginning students must first learn what the scientific method entails. The next step is to apply their understanding of scientific method by identifying design elements in existing research. For example, any detailed description of an experimental design can help students practice distinguishing the independent from the dependent variable and identifying how researchers controlled for alternative explanations. The next methodological critical thinking goals include evaluating the quality of existing research design and challenging the conclusions of research findings. Students may need to feel empowered by the teacher to overcome the reverence they sometimes demonstrate for anything in print, including their textbooks. Asking students to do a critical analysis on a fairly sophisticated design may simply be too big a leap for them to make. They are likely to fare better if given examples of bad design so they can build their critical abilities and confidence in order to tackle more sophisticated designs. (Examples of bad design can be found in The Critical Thinking Companion for Introductory Psychology or they can be easily constructed with a little time and imagination). Students will develop and execute their own research designs in their capstone methodology courses. Asking students to conduct their own independent research, whether a comprehensive survey on parental attitudes, a naturalistic study of museum patrons’ behavior, or a well-designed experiment on paired associate learning, prompts students to integrate their critical thinking skills and gives them practice with conventional writing forms in psychology. In evaluating their work I have found it helpful to ask students to identify the strengths and weaknesses of their own work- as an additional opportunity to think critically-before giving them my feedback.

Additional Suggestions

Adopting explicit critical thinking objectives, regardless of the domain of critical thinking, may entail some strategy changes on the part of the teacher.

• Introduce psychology as an ope n-end ed, growing enterprise . Students often think that their entry into the discipline represents an end-point where everything good and true has already been discovered. That conclusion encourages passivity rather than criticality. Point out that research is psychology’ s way of growing and developing. Each new discovery in psychology represents a potentially elegant act of critical thinking. A lot of room for discovery remains. New ideas will be developed and old conceptions discarded.

• Require student performance that goes beyond memorization . Group work, essays, debates, themes, letters to famous psychologists, journals, current event examples- all of these and more can be used as a means of developing the higher skills involved in critical thinking in psychology. Find faulty cause-effect conclusions in the tabloids (e.g., “Eating broccoli increases your IQ!”) and have students design studies to confirm or discredit the headline’s claims. Ask students to identify what kinds of evidence would warrant belief in commercial claims. Although it is difficult, even well designed objective test items can capture critical thinking skills so that students are challenged beyond mere repetition and recall.

• Clarify your expectations about performance with explicit, public criteria. Devising clear performance criteria for psychology projects will enhance student success. Students often complain that they don’t understand “what you want” when you assign work. Performance criteria specify the standards that you will use to evaluate their work. For example, perfonnance criteria for the observation exercise described earlier might include the following: The student describes behavior accurately; offers i nference that is reasonable for the context; and identifies personal factors that might influence infer ence. Perfonnance criteria facilitate giving detailed feedback easily and can also promote student self-assessment.

• Label good examples of critical thinking when these occur spontaneously. Students may not recognize when they are thinking critically. When you identify examples of good thinking or exploit examples that could be improved, it enhances students’ ability to understand. One of my students made this vivid for me when she commented on the good connection she had made between a course concept and an insight from her literature class, “That is what you mean by critical thinking?” There after I have been careful to label a good critical thinking insight.

• Endorse a questioning attitude. Students often assume that if they have questions about their reading, then they are somehow being dishonorable, rude, or stupid. Having  discussions early in the course about the role of good questions in enhancing the quality of the subject and expanding the sharpness of the mind may set a more critical stage on which students can play. Model critical thinking from some insights you have had about behavior or from some research you have conducted in the past. Congratulate students who offer good examples of the principles under study. Thank students who ask concept-related questions and describe why you think their questions are good. Leave time and space for more. Your own excitement about critical thinking can be a great incentive for students to seek that excitement.

• Brace yourself . When you include more opportunity for student critical thinking in class, there is much more opportunity for the class to go astray. Stepping away from the podium and engaging the students to perform what they know necessitates some loss of control, or at least some enhanced risk. However, the advantage is that no class will ever feel completely predictable, and this can be a source of stimulation for students and the professor as well.

As far back as I can remember over 50 yrs. ago. I have been talking psychology to friends, or helping them to solve problems. I never thought about psy. back then, but now I realize I really love helping people. How can I become a critical thinker without condemning people?

3.1: Critical Thinking in College Writing - From the Personal to the Academic

There is something about the term “critical thinking” that makes you draw a blank every time you think about what it means.* It seems so fuzzy and abstract that you end up feeling uncomfortable, as though the term is thrust upon you, demanding an intellectual effort that you may not yet have. But you know it requires you to enter a realm of smart, complex ideas that others have written about and that you have to navigate, understand, and interact with just as intelligently. It’s a lot to ask for. It makes you feel like a stranger in a strange land.

As a writing teacher I am accustomed to reading and responding to difficult texts. In fact, I like grappling with texts that have interesting ideas no matter how complicated they are because I understand their value. I have learned through my years of education that what ultimately engages me, keeps me enthralled, is not just grammatically pristine, fluent writing, but writing that forces me to think beyond the page. It is writing where the writer has challenged herself and then offered up that challenge to the reader, like a baton in a relay race. The idea is to run with the baton.

You will often come across critical thinking and analysis as requirements for assignments in writing and upper-level courses in a variety of disciplines. Instructors have varying explanations of what they actually require of you, but, in general, they expect you to respond thoughtfully to texts you have read. The first thing you should remember is not to be afraid of critical thinking. It does not mean that you have to criticize the text, disagree with its premise, or attack the writer simply because you feel you must. Criticism is the process of responding to and evaluating ideas, argument, and style so that readers understand how and why you value these items.

Critical thinking is also a process that is fundamental to all disciplines. While in this essay I refer mainly to critical thinking in composition, the general principles behind critical thinking are strikingly similar in other fields and disciplines. In history, for instance, it could mean examining and analyzing primary sources in order to understand the context in which they were written. In the hard sciences, it usually involves careful reasoning, making judgments and decisions, and problem solving. While critical thinking may be subject-specific, that is to say, it can vary in method and technique depending on the discipline, most of its general principles such as rational thinking, making independent evaluations and judgments, and a healthy skepticism of what is being read, are common to all disciplines. No matter the area of study, the application of critical thinking skills leads to clear and flexible thinking and a better understanding of the subject at hand.

To be a critical thinker you not only have to have an informed opinion about the text but also a thoughtful response to it. There is no doubt that critical thinking is serious thinking, so here are some steps you can take to become a serious thinker and writer.

Attentive Reading: A Foundation for Critical Thinking

A critical thinker is always a good reader because to engage critically with a text you have to read attentively and with an open mind, absorbing new ideas and forming your own as you go along. Let us imagine you are reading an essay by Annie Dillard, a famous essayist, called “Living like Weasels.” Students are drawn to it because the idea of the essay appeals to something personally fundamental to all of us: how to live our lives. It is also a provocative essay that pulls the reader into the argument and forces a reaction, a good criterion for critical thinking.

So let’s say that in reading the essay you encounter a quote that gives you pause. In describing her encounter with a weasel in Hollins Pond, Dillard says, “I would like to learn, or remember, how to live . . . I don’t think I can learn from a wild animal how to live in particular . . . but I might learn something of mindlessness, something of the purity of living in the physical senses and the dignity of living without bias or motive” (220). You may not be familiar with language like this. It seems complicated, and you have to stop ever so often (perhaps after every phrase) to see if you understood what Dillard means. You may ask yourself these questions:

• What does “mindlessness” mean in this context?
• How can one “learn something of mindlessness?”
• What does Dillard mean by “purity of living in the physical senses?”
• How can one live “without bias or motive?”

These questions show that you are an attentive reader. Instead of simply glossing over this important passage, you have actually stopped to think about what the writer means and what she expects you to get from it. Here is how I read the quote and try to answer the questions above: Dillard proposes a simple and uncomplicated way of life as she looks to the animal world for inspiration. It is ironic that she admires the quality of “mindlessness” since it is our consciousness, our very capacity to think and reason, which makes us human, which makes us beings of a higher order. Yet, Dillard seems to imply that we need to live instinctually, to be guided by our senses rather than our intellect. Such a “thoughtless” approach to daily living, according to Dillard, would mean that our actions would not be tainted by our biases or motives, our prejudices. We would go back to a primal way of living, like the weasel she observes. It may take you some time to arrive at this understanding on your own, but it is important to stop, reflect, and ask questions of the text whenever you feel stumped by it. Often such questions will be helpful during class discussions and peer review sessions.

Listing Important Ideas

When reading any essay, keep track of all the important points the writer makes by jotting down a list of ideas or quotations in a notebook. This list not only allows you to remember ideas that are central to the writer’s argument, ideas that struck you in some way or the other, but it also you helps you to get a good sense of the whole reading assignment point by point. In reading Annie Dillard’s essay, we come across several points that contribute toward her proposal for better living and that help us get a better understanding of her main argument. Here is a list of some of her ideas that struck me as important:

• “The weasel lives in necessity and we live in choice, hating necessity and dying at the last ignobly in its talons” (220).
• “And I suspect that for me the way is like the weasel’s: open to time and death painlessly, noticing everything, remembering nothing, choosing the given with a fierce and pointed will” (221).
• “We can live any way we want. People take vows of poverty, chastity, and obedience—even of silence—by choice. The thing is to stalk your calling in a certain skilled and supple way, to locate the most tender and live spot and plug into that pulse” (221).
• “A weasel doesn’t ‘attack’ anything; a weasel lives as he’s meant to, yielding at every moment to the perfect freedom of single necessity” (221).
• “I think it would be well, and proper, and obedient, and pure, to grasp your one necessity and not let it go, to dangle from it limp wherever it takes you” (221).

These quotations give you a cumulative sense of what Dillard is trying to get at in her essay, that is, they lay out the elements with which she builds her argument. She first explains how the weasel lives, what she learns from observing the weasel, and then prescribes a lifestyle she admires—the central concern of her essay.

Noticing Key Terms and Summarizing Important Quotes

Within the list of quotations above are key terms and phrases that are critical to your understanding of the ideal life as Dillard describes it. For instance, “mindlessness,” “instinct,” “perfect freedom of a single necessity,” “stalk your calling,” “choice,” and “fierce and pointed will” are weighty terms and phrases, heavy with meaning, that you need to spend time understanding. You also need to understand the relationship between them and the quotations in which they appear. This is how you might work on each quotation to get a sense of its meaning and then come up with a statement that takes the key terms into account and expresses a general understanding of the text:

Quote 1: Animals (like the weasel) live in “necessity,” which means that their only goal in life is to survive. They don’t think about how they should live or what choices they should make like humans do. According to Dillard, we like to have options and resist the idea of “necessity.” We fight death—an inevitable force that we have no control over—and yet ultimately surrender to it as it is the necessary end of our lives.

Quote 2: Dillard thinks the weasel’s way of life is the best way to live. It implies a pure and simple approach to life where we do not worry about the passage of time or the approach of death. Like the weasel, we should live life in the moment, intensely experiencing everything but not dwelling on the past. We should accept our condition, what we are “given,” with a “fierce and pointed will.” Perhaps this means that we should pursue our one goal, our one passion in life, with the same single-minded determination and tenacity that we see in the weasel.

Quote 3: As humans, we can choose any lifestyle we want. The trick, however, is to go after our one goal, one passion like a stalker would after a prey.

Quote 4: While we may think that the weasel (or any animal) chooses to attack other animals, it is really only surrendering to the one thing it knows: its need to live. Dillard tells us there is “the perfect freedom” in this desire to survive because to her, the lack of options (the animal has no other option than to fight to survive) is the most liberating of all.

Quote 5: Dillard urges us to latch on to our deepest passion in life (the “one necessity”) with the tenacity of a weasel and not let go. Perhaps she’s telling us how important it is to have an unwavering focus or goal in life.

Writing a Personal Response: Looking Inward

Dillard’s ideas will have certainly provoked a response in your mind, so if you have some clear thoughts about how you feel about the essay this is the time to write them down. As you look at the quotes you have selected and your explanation of their meaning, begin to create your personal response to the essay. You may begin by using some of these strategies:

• Tell a story. Has Dillard’s essay reminded you of an experience you have had? Write a story in which you illustrate a point that Dillard makes or hint at an idea that is connected to her essay.
• Focus on an idea from Dillard’s essay that is personally important to you. Write down your thoughts about this idea in a first person narrative and explain your perspective on the issue.
• If you are uncomfortable writing a personal narrative or using “I” (you should not be), reflect on some of her ideas that seem important and meaningful in general. Why were you struck by these ideas?
• Write a short letter to Dillard in which you speak to her about the essay. You may compliment her on some of her ideas by explaining why you like them, ask her a question related to her essay and explain why that question came to you, and genuinely start up a conversation with her.

This stage in critical thinking is important for establishing your relationship with a text. What do I mean by this “relationship,” you may ask? Simply put, it has to do with how you feel about the text. Are you amazed by how true the ideas seem to be, how wise Dillard sounds? Or are you annoyed by Dillard’s let-me-tell-you-how-to-live approach and disturbed by the impractical ideas she so easily prescribes? Do you find Dillard’s voice and style thrilling and engaging or merely confusing? No matter which of the personal response options you select, your initial reaction to the text will help shape your views about it.

Making an Academic Connection: Looking Outward

First year writing courses are designed to teach a range of writing— from the personal to the academic—so that you can learn to express advanced ideas, arguments, concepts, or theories in any discipline. While the example I have been discussing pertains mainly to college writing, the method of analysis and approach to critical thinking I have demonstrated here will serve you well in a variety of disciplines. Since critical thinking and analysis are key elements of the reading and writing you will do in college, it is important to understand how they form a part of academic writing. No matter how intimidating the term “academic writing” may seem (it is, after all, associated with advanced writing and becoming an expert in a field of study), embrace it not as a temporary college requirement but as a habit of mind.

To some, academic writing often implies impersonal writing, writing that is detached, distant, and lacking in personal meaning or relevance. However, this is often not true of the academic writing you will do in a composition class. Here your presence as a writer—your thoughts, experiences, ideas, and therefore who you are—is of much significance to the writing you produce. In fact, it would not be farfetched to say that in a writing class academic writing often begins with personal writing. Let me explain. If critical thinking begins with a personal view of the text, academic writing helps you broaden that view by going beyond the personal to a more universal point of view. In other words, academic writing often has its roots in one’s private opinion or perspective about another writer’s ideas but ultimately goes beyond this opinion to the expression of larger, more abstract ideas. Your personal vision—your core beliefs and general approach to life— will help you arrive at these “larger ideas” or universal propositions that any reader can understand and be enlightened by, if not agree with. In short, academic writing is largely about taking a critical, analytical stance toward a subject in order to arrive at some compelling conclusions.

Let us now think about how you might apply your critical thinking skills to move from a personal reaction to a more formal academic response to Annie Dillard’s essay. The second stage of critical thinking involves textual analysis and requires you to do the following:

• Summarize the writer’s ideas the best you can in a brief paragraph. This provides the basis for extended analysis since it contains the central ideas of the piece, the building blocks, so to speak.
• Evaluate the most important ideas of the essay by considering their merits or flaws, their worthiness or lack of worthiness. Do not merely agree or disagree with the ideas but explore and explain why you believe they are socially, politically, philosophically, or historically important and relevant, or why you need to question, challenge, or reject them.
• Identify gaps or discrepancies in the writer’s argument. Does she contradict herself? If so, explain how this contradiction forces you to think more deeply about her ideas. Or if you are confused, explain what is confusing and why.
• Examine the strategies the writer uses to express her ideas. Look particularly at her style, voice, use of figurative language, and the way she structures her essay and organizes her ideas. Do these strategies strengthen or weaken her argument? How?
• Include a second text—an essay, a poem, lyrics of a song— whose ideas enhance your reading and analysis of the primary text. This text may help provide evidence by supporting a point you’re making, and further your argument.
• Extend the writer’s ideas, develop your own perspective, and propose new ways of thinking about the subject at hand.

Crafting the Essay

Once you have taken notes and developed a thorough understanding of the text, you are on your way to writing a good essay. If you were asked to write an exploratory essay, a personal response to Dillard’s essay would probably suffice. However, an academic writing assignment requires you to be more critical. As counter-intuitive as it may sound, beginning your essay with a personal anecdote often helps to establish your relationship to the text and draw the reader into your writing. It also helps to ease you into the more complex task of textual analysis. Once you begin to analyze Dillard’s ideas, go back to the list of important ideas and quotations you created as you read the essay. After a brief summary, engage with the quotations that are most important, that get to the heart of Dillard’s ideas, and explore their meaning. Textual engagement, a seemingly slippery concept, simply means that you respond directly to some of Dillard’s ideas, examine the value of Dillard’s assertions, and explain why they are worthwhile or why they should be rejected. This should help you to transition into analysis and evaluation. Also, this part of your essay will most clearly reflect your critical thinking abilities as you are expected not only to represent Dillard’s ideas but also to weigh their significance. Your observations about the various points she makes, analysis of conflicting viewpoints or contradictions, and your understanding of her general thesis should now be synthesized into a rich new idea about how we should live our lives. Conclude by explaining this fresh point of view in clear, compelling language and by rearticulating your main argument.

Modeling Good Writing

When I teach a writing class, I often show students samples of really good writing that I’ve collected over the years. I do this for two reasons: first, to show students how another freshman writer understood and responded to an assignment that they are currently working on; and second, to encourage them to succeed as well. I explain that although they may be intimidated by strong, sophisticated writing and feel pressured to perform similarly, it is always helpful to see what it takes to get an A. It also helps to follow a writer’s imagination, to learn how the mind works when confronted with a task involving critical thinking. The following sample is a response to the Annie Dillard essay. Figure 1 includes the entire student essay and my comments are inserted into the text to guide your reading.

Though this student has not included a personal narrative in his essay, his own world-vievvw is clear throughout. His personal point of view, while not expressed in first person statements, is evident from the very beginning. So we could say that a personal response to the text need not always be expressed in experiential or narrative form but may be present as reflection, as it is here. The point is that the writer has traveled through the rough terrain of critical thinking by starting out with his own ruminations on the subject, then by critically analyzing and responding to Dillard’s text, and finally by developing a strong point of view of his own about our responsibility as human beings. As readers we are engaged by clear, compelling writing and riveted by critical thinking that produces a movement of ideas that give the essay depth and meaning. The challenge Dillard set forth in her essay has been met and the baton passed along to us.

• Write about your experiences with critical thinking assignments. What seemed to be the most difficult? What approaches did you try to overcome the difficulty?
• Respond to the list of strategies on how to conduct textual analysis. How well do these strategies work for you? Add your own tips to the list.
• Evaluate the student essay by noting aspects of critical thinking that are evident to you. How would you grade this essay? What other qualities (or problems) do you notice?

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o’clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68–69; 1933: 91–92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot’s position, it must appear to project far out in front of the boat. Moreover, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69–70; 1933: 92–93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond lane from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses. As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009, 2021), others on the resulting judgment (Facione 1990a), and still others on responsiveness to reasons (Siegel 1988). Kuhn (2019) takes critical thinking to be more a dialogic practice of advancing and responding to arguments than an individual ability.

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in spacing in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the spacing of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016a) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Facione (1990a: 25) divides “affective dispositions” of critical thinking into approaches to life and living in general and approaches to specific issues, questions or problems. Adapting this distinction, one can usefully divide critical thinking dispositions into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking. In three studies, Haran, Ritov, & Mellers (2013) found that actively open-minded thinking, including “the tendency to weigh new evidence against a favored belief, to spend sufficient time on a problem before giving up, and to consider carefully the opinions of others in forming one’s own”, led study participants to acquire information and thus to make accurate estimations.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), Black (2012), and Blair (2021).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work. It is also helpful to be aware of the prevalence of “noise” (unwanted unsystematic variability of judgments), of how to detect noise (through a noise audit), and of how to reduce noise: make accuracy the goal, think statistically, break a process of arriving at a judgment into independent tasks, resist premature intuitions, in a group get independent judgments first, favour comparative judgments and scales (Kahneman, Sibony, & Sunstein 2021). It is helpful as well to be aware of the concept of “bounded rationality” in decision-making and of the related distinction between “satisficing” and optimizing (Simon 1956; Gigerenzer 2001).

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? In a comprehensive meta-analysis of experimental and quasi-experimental studies of strategies for teaching students to think critically, Abrami et al. (2015) found that dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), Bailin et al. (1999b), and Willingham (2019).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

Critical Thinking: Definition and Analysis

This essay about the significance of critical thinking in various aspects of life, from academia to everyday interactions. It emphasizes the importance of analysis and synthesis in fostering intellectual autonomy and resilience. Through examples in different contexts, it highlights how critical thinking enables individuals to navigate complex information, evaluate arguments, and cultivate intellectual humility.

How it works

Critical thinking, a term often echoed in scholarly circles, workplaces, and beyond, is a skill of immense significance across various dimensions of life. It serves as the cornerstone of education, problem-solving, decision-making, and personal development. However, despite its ubiquitous presence, the concept of critical thinking remains somewhat enigmatic, with its definition subject to interpretation and nuanced understanding. In this exploration, we delve into the depths of critical thinking, endeavoring to unravel its essence, dissect its components, and illuminate its implications.

At its essence, critical thinking can be described as the ability to analyze, evaluate, and synthesize information or arguments in a systematic and reasoned manner.

It goes beyond mere acceptance or rejection of ideas; rather, it involves a rigorous examination of evidence, assumptions, and logical coherence. Critical thinkers engage in reflective and independent thinking, questioning assumptions, exploring alternative perspectives, and arriving at well-informed conclusions. Essentially, critical thinking acts as intellectual armor, equipping individuals with the tools to navigate the complex landscape of information and ideas in today’s world.

One of the foundational elements of critical thinking is analysis. Analysis entails breaking down complex ideas or issues into their constituent parts, closely examining them, and discerning patterns, relationships, or implications. It serves as the scaffolding for reasoned judgments by providing a framework for understanding. During analysis, evidence is scrutinized, biases are uncovered, the credibility of sources is assessed, and underlying assumptions are revealed. Through this process, a deeper understanding of the subject matter is attained, enabling individuals to evaluate its strengths and weaknesses more effectively.

However, analysis in critical thinking is not limited to deconstruction; it also involves synthesis – the integration of disparate elements into a coherent whole. Synthesis represents the culmination of analytical inquiry, where insights gleaned from individual pieces of information or perspectives are merged to form a comprehensive understanding. It is the creative aspect of critical thinking, where innovative ideas or solutions emerge from the interplay of diverse viewpoints. Thus, analysis and synthesis work in tandem to foster holistic comprehension and innovative thinking.

To underscore the significance of analysis in critical thinking, one can examine its application across various contexts. In academia, students are frequently tasked with analyzing literary texts, scientific data, historical events, or philosophical arguments. Through close examination, experimentation, or historical research, students learn to dissect complex phenomena, identify underlying themes or principles, and construct coherent interpretations. Similarly, professionals in fields such as business, law, or healthcare rely on analytical skills to dissect problems, assess risks, and formulate effective strategies. Whether it involves conducting market research, analyzing legal precedents, or diagnosing medical conditions, the ability to analyze information critically is indispensable.

Moreover, analysis in critical thinking extends beyond academic or professional domains; it permeates everyday life. Consider the deluge of information encountered through media channels, social networks, or interpersonal interactions. In an era of information overload and misinformation, the ability to analyze sources critically is paramount. Individuals must scrutinize news articles for bias, fact-check viral claims, and discern the agenda behind persuasive rhetoric. By honing analytical skills, individuals become less susceptible to manipulation and more adept at navigating the complexities of the modern world.

Furthermore, analysis in critical thinking fosters intellectual humility – the recognition of one’s fallibility and the willingness to revise beliefs in light of new evidence or perspectives. In a world marked by ideological polarization and echo chambers, intellectual humility is a rare trait. However, critical thinkers, through their commitment to rational inquiry and open-mindedness, cultivate this virtue. They recognize that truth is multifaceted and elusive, and that certainty is often illusory. Consequently, they approach arguments or viewpoints with skepticism, subjecting them to rigorous analysis before rendering judgment.

In conclusion, critical thinking, grounded in analysis, is an indispensable skill for navigating the complexities of the modern world. It empowers individuals to dissect information, evaluate arguments, and synthesize insights, fostering intellectual autonomy and resilience. Whether in academia, professional endeavors, or everyday life, the ability to think critically is indispensable. By honing analytical skills and nurturing intellectual humility, individuals can traverse the vast expanse of information and ideas with clarity and discernment. As dedicated practitioners of critical thinking, let us embrace the challenge of analysis, for therein lies the path to intellectual enlightenment and empowerment.

How to demonstrate critical evaluation in your psychology assignments

Thinking critically about psychology research

Critical thinking is often taught in undergraduate psychology degrees, and is a key marking criteria for higher marks in many assignments. But getting your head around how to write critically can sometimes be difficult. It can take practice. The aim of this short blog is to provide an introduction to critical evaluation, and how to start including evidence of critical evaluation in your psychology assignments.

So what does “critical evaluation” really mean?

Broadly speaking, critical evaluation is the process of thinking and writing critically about the quality of the sources of evidence used to support or refute an argument. By “ evidence “, I mean the literature you cite (e.g., a journal article or book chapter). By “ quality   of the evidence “, I mean thinking about whether this topic has been tested is in a robust way. If the quality of the sources is poor, then this could suggest poor support for your argument, and vice versa. Even if the quality is poor, this is important to discuss in your assignments as evidence of critical thinking in this way!

In the rest of this blog, I outline a few different ways you can start to implement critical thinking into your work and reading of psychology. I talk about the quality of the evidence, a few pointers for critiquing the methods, theoretical and practical critical evaluation too. This is not an exhaustive list, but hopefully it’ll help you to start getting those higher-level marks in psychology. I also include an example write-up at the end to illustrate how to write all of this up!

The quality of the evidence

There are different types of study designs in psychology research, but some are of higher quality than others. The higher the quality of the evidence, the stronger the support for your argument the research offers, because the idea has been tested more rigorously. The pyramid image below can really help to explain what we mean by “quality of evidence”, by showing different study designs in the order of their quality. 

Not every area of psychology is going to be full of high quality studies, and even the strongest sources of evidence (i.e., systematic reviews and/or meta-analyses) can have limitations! Because no study is perfect, it can be a good habit to tell the reader, in your report, (i) what the  design  of the study is that you’re citing, AND, (ii)  how  this affects your argument. Doing so would be evidence of critical thought. (See an example write-up below for implementing this, but do not copy and paste it!) 

But first, what do I mean by “design”? The design of the study refers to  how  the study was carried out. There are sometimes broad categories of design that you’ll have heard of, like a ‘survey design’, ‘a review paper’, or an ‘experimental design’. Within these categories, though, there can be more specific types of design (e.g. a  cross-sectional  survey design, or a  longitudinal  survey design; a  randomised controlled  experiment or a  simple pre-post  experiment). Knowing these specific types of design is a good place to start when thinking about how to critique the evidence when citing your sources, and the image below can help with that. 

Image source: https://thelogicofscience.com/2016/01/12/the-hierarchy-of-evidence-is-the-studys-design-robust/

In summary, there are various types of designs in psychology research. To name a few from the image above, we have: a meta-analysis or a systematic review (a review paper that summarises the research that explores the same research question); a cross-sectional survey study (a questionnaire that people complete once – these are really common in psychology!). If you’re not familiar with these, I would  highly suggest  doing a bit of reading around these methods and some of their general limitations – you can then use these limitation points in your assignments! To help with this, you could do a Google Scholar search for ‘limitations of a cross-sectional study’, or ‘why are randomised control trials gold standard?’. You can use any published papers as further support as a limitation.

Methodological critical evaluation

• Internal validity: Are the findings or the measures used in the study reliable (e.g., have they been replicated by another study, and is the reliability high)? 
• External validity: Are there any biases in the study that might affect generalisability(e.g., gender bias, where one gender may be overrepresented for the population in the sample recruited)?  Lack of generalisability is a common limitation that undergraduates tend to use by default as a limitation in their reports. It’s a perfectly valid limitation, but it can usually be made much more impactful by explaining exactly  how  it’s a problem for the topic of study. In some cases, this limitation may not be all that warranted; for example, a female bias may be expected in a sample of psychology students, because undergraduate courses tend to be filled mostly with females! 
• What is the design of the study, and how it a good or bad quality design (randomised control trial, cross-sectional study)? 

Theoretical critical evaluation

• Do the findings in the literature support the relevant psychological theories?
• Have the findings been replicated in another study? (If so, say so and add a reference!)

Practical critical evaluation

• In the real world, how easy would it be to implement these findings?
• Have these findings been implemented? (If so, you could find out if this has been done well!)

Summary points

In summary, there are various types of designs in psychology research. To name a few from the image above, we have: a meta-analysis or a systematic review (a review paper that summarises the research that explores the same research question); a cross-sectional survey study (a questionnaire that people complete once – these are really common in psychology!). If you’re not familiar with these, I would highly suggest doing a bit of reading around these methods and some of their general limitations – you can then use these limitation points in your assignments! To help with this, I would do a Google Scholar search for ‘limitations of a cross-sectional study’, or ‘why are randomised control trials gold standard?’. You can use these papers as further support as a limitation.

You don’t have to use all of these points in your writing, these are just examples of how you can demonstrate critical thinking in your work. Try to use at least a couple in any assignment. Here is an example of how to write these up:

An example write-up

“Depression and anxiety are generally associated with each other (see the meta-analysis by [reference here]). For example, one of these studies was a cross-sectional study [reference here] with 500 undergraduate psychology students. The researchers found that depression and anxiety (measured using the DASS-21 measure) were correlated at  r  = .76, indicating a strong effect. However, this one study is limited in that it used a cross-sectional design, which do not tell us whether depression causes anxiety or whether anxiety causes depression; it just tells us that they are correlated. It’s also limited in that the participants are not a clinical sample, which does not tell us about whether these are clinically co-morbid constructs. Finally, a strength of this study is that it used the DASS-21 which is generally found to be a reliable measure. Future studies would therefore benefit from using a longitudinal design to gain an idea as to how these variables are causally related to one another, and use more clinical samples to understand the implications for clinical practice. Overall, however, the research generally suggests that depression and anxiety are associated. That there is a meta-analysis on this topic [reference here], showing that there is lots of evidence, suggests that this finding is generally well-accepted.”

• Notice how I first found a review paper on the topic to broadly tell the reader how much evidence there is in the first place. I set the scene of the paragraph with the first sentence, and then the last sentence I brought it back, rounding the paragraph off. 
• Notice how I then described one study from this paper in more detail. Specifically, I mentioned the participants, the design of the study and the measure the researchers used to assess these variables. Critically, I then described  how  each of these pieces of the method are disadvantages/strengths of the study. Sometimes, it’s enough to just say “the study was limited in that it was a cross-sectional study”, but it can really show that you are thinking critically, if you also add “… because it does not tell us….”. 
• Notice how I added a statistic there to further illustrate my point (in this case, it was the correlation coefficient), showing that I didn’t just read the abstract of the paper. Doing this for the effect sizes in a study can also help demonstrate to a reader that you understand statistics (a higher-level marking criteria). 

Are these points you can include in your own work?

🤔 what is a critical thinking essay.

A critical thinking essay is a paper that analyses an issue and reflects on it in order to develop an action plan. Unlike other essay types, it starts with a question instead of a thesis. It helps you develop a broader perspective on a specific issue. Critical writing aims at improving your analytical skills and encourages asking questions.

Critical Thinking in Writing: Importance

When we talk about critical thinking and writing, the word “critical” doesn’t have any negative connotation. It simply implies thorough investigation, evaluation, and analysis of information. Critical thinking allows students to make objective conclusions and present their ideas logically. It also helps them avoid errors in reasoning.

The Basics: 8 Steps of Critical Thinking Psychology

Did you know that the critical thinking process consists of 8 steps? We’ve listed them below. You can try to implement them in your everyday life:

It’s possible that fallacies will occur during the process of critical thinking. Fallacies are errors in reasoning that fail to provide a reasonable conclusion. Here are some common types of fallacies:

Just in 1 hour! We will write you a plagiarism-free paper in hardly more than 1 hour

• Generalization . It happens when you apply generally factual statements to a specific case.
• Ambiguity . It occurs when the arguments are not clear and are not supported by evidence.
• Appeal to authority . This mistake happens when you claim the statement is valid only because a respected person made it.
• Appeal to emotion . It occurs when you use highly emotive language to convince the audience. Try to stay sensible and rely on the evidence.
• Bifurcation . This mistake occurs when you choose only between two alternatives when more than two exist.
• False analogy . It happens when the examples are poorly connected.

If you want to avoid these mistakes, do the following:

• try not to draw conclusions too quickly,
• be attentive,
• carefully read through all the sources,
• avoid generalizations.

How to Demonstrate Your Critical Thinking in Writing

Critical thinking encourages you to go beyond what you know and study new perspectives. When it comes to demonstrating your critical thinking skills in writing, you can try these strategies:

• Read . Before you start writing an essay, read everything you can find on the subject you are about to cover. Focus on the critical points of your assignment.
• Research . Look up several scholarly sources and study the information in-depth.
• Evaluate . Analyze the sources and the information you’ve gathered. See whether you can disagree with the authors.
• Prove . Explain why you agree or disagree with the authors’ conclusions. Back it up with evidence.

According to Purdue University, logical essay writing is essential when you deal with academic essays. It helps you demonstrate and prove the arguments. Make sure that your paper reaches a logical conclusion.

There are several main concepts related to logic:

If you want your essay to be logical, it’s better to avoid syllogistic fallacies, which happen with certain invalid deductions. If syllogisms are used carelessly, they can lead to false statements and ruin the credibility of your paper.

✅ How to Write a Critical Thinking Essay Step by Step

Now, let’s focus on planning and writing your critical thinking essay. In this section, you will find an essay outline, examples of thesis statements, and a brief overview of each essay part.

Critical Thinking Essay Outline

In a critical thinking essay, there are two main things to consider: a premise and a conclusion :

• A premise is a statement in the argument that explains the reason or supports a conclusion.
• A conclusion indicates what the argument is trying to prove. Each argument can have only one conclusion.

When it comes to structuring, a critical thinking essay is very similar to any other type of essay. Before you start writing it, make sure you know what to include in it. An outline is very helpful when it comes to structuring a paper.

How to Start a Critical Essay Introduction

An introduction gives readers a general idea of an essay’s contents. When you work on the introduction, imagine that you are drawing a map for the reader. It not only marks the final destination but also explains the route.

An introduction usually has 4 functions:

• It catches the reader’s attention;
• It states the essay’s main argument;
• It provides some general information about the topic;
• It shows the importance of the issue in question.

Here are some strategies that can make the introduction writing easier:

• Give an overview of the essay’s topic.
• Express the main idea.
• Define the main terms.
• Outline the issues that you are going to explore or argue about.
• Explain the methodology and why you used it.
• Write a hook to attract the reader’s attention.

Critical Analysis Thesis Statement & Examples

A thesis statement is an integral part of every essay. It keeps the paper organized and guides both the reader and the writer. A good thesis:

• expresses the conclusion or position on a topic;
• justifies your position or opinion with reasoning;
• conveys one idea;
• serves as the essay’s map.

To have a clearer understanding of what a good thesis is, let’s have a look at these examples.

The statement on the left is too general and doesn’t provide any reasoning. The one on the right narrows down the group of people to office workers and specifies the benefits of exercising.

Critical Thinking Essay Body Paragraphs: How to Write

Body paragraphs are the part of the essay where you discuss all the ideas and arguments. In a critical thinking essay, arguments are especially important. When you develop them, make sure that they:

• reflect the key theme;
• are supported by the sources/citations/examples.

Using counter-arguments is also effective. It shows that you acknowledge different points of view and are not easily persuaded.

In addition to your arguments, it’s essential to present the evidence . Demonstrate your critical thinking skills by analyzing each source and stating whether the author’s position is valid.

To make your essay logically flow, you may use transitions such as:

• Accordingly,
• For instance,
• On the contrary,
• In conclusion,
• Not only… but also,
• Undoubtedly.

How to Write a Critical Thinking Conclusion

In a critical thinking essay, the notion of “conclusion” is tightly connected to the one used in logic. A logical conclusion is a statement that specifies the author’s point of view or what the essay argues about. Each argument can have only one logical conclusion.

Sometimes they can be confused with premises. Remember that premises serve as a support for the conclusion. Unlike the conclusion, there can be several premises in a single argument. You can learn more about these concepts from the article on a logical consequence by Stanford Encyclopedia of Philosophy.

Keeping this in mind, have a look at these tips for finishing your essay:

• Briefly sum up the main points.
• Provide a final thought on the issue.
• Suggest some results or consequences.
• Finish up with a call for action.

📑 Critical Thinking Essays Examples & Formatting Tips

Formatting is another crucial aspect of every formal paper. MLA and APA are two popular formats when it comes to academic writing. They share some similarities but overall are still two different styles. Here are critical essay format guidelines that you can use as a reference:

Finally, you’re welcome to check out a full critical essay sample in MLA format. Download the PDF file below:

Currently, the importance of critical thinking has grown rapidly because technological progress has led to expanded access to various content-making platforms: websites, online news agencies, and podcasts with, often, low-quality information. Fake news is used to achieve political and financial aims, targeting people with low news literacy. However, individuals can stop spreading fallacies by detecting false agendas with the help of a skeptical attitude.

✍️ Bonus Tips: Critical Thinking and Writing Exercises

Critical thinking is a process different from our regular thinking. When we think in everyday life, we do it automatically. However, when we’re thinking critically, we do it deliberately.

So how do we get better at this type of thinking and make it a habit? These useful tips will help you do it:

• Ask basic questions. Sometimes, while we are doing research, the explanation becomes too complicated. To avoid it, always go back to your topic.
• Question basic assumptions. When thinking through a problem, ask yourself whether your beliefs can be wrong. Keep an open mind while researching your question.
• Think for yourself. Avoid getting carried away in the research and buying into other people’s opinions.
• Reverse things. Sometimes it seems obvious that one thing causes another, but what if it’s the other way around?
• Evaluate existing evidence. If you work with sources, it’s crucial to evaluate and question them.

Another way to improve your reasoning skills is to do critical thinking exercises. Here are some of them:

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.

18. Decision Making

A store manager decides which products to order more of based on what's selling best.

19. Setting Goals

A team leader helps their team decide what tasks are most important to finish this month and which can wait.

20. Evaluating Ideas

At a team meeting, everyone shares ideas for a new project. The group discusses each idea's pros and cons before picking one.

21. Handling Conflict

Two workers disagree on how to do a job. Instead of arguing, they talk calmly, listen to each other, and find a solution they both like.

22. Improving Processes

A cashier thinks of a faster way to ring up items so customers don't have to wait as long.

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

A business owner thinks about what might happen in the next few years, like new competitors or changes in what customers want, and makes plans based on those thoughts.

26. Understanding Perspectives

A team is designing a new toy. They think about what kids and parents would both like instead of just what they think is fun.

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

For a psychology project, students plan an experiment to understand how people's memories work and think of ways to ensure accurate results.

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.

Critical thinking definition

Critical thinking, as described by Oxford Languages, is the objective analysis and evaluation of an issue in order to form a judgement.

Active and skillful approach, evaluation, assessment, synthesis, and/or evaluation of information obtained from, or made by, observation, knowledge, reflection, acumen or conversation, as a guide to belief and action, requires the critical thinking process, which is why it's often used in education and academics.

Some even may view it as a backbone of modern thought.

However, it's a skill, and skills must be trained and encouraged to be used at its full potential.

People turn up to various approaches in improving their critical thinking, like:

• Developing technical and problem-solving skills
• Engaging in more active listening
• Actively questioning their assumptions and beliefs
• Seeking out more diversity of thought
• Opening up their curiosity in an intellectual way etc.

Is critical thinking useful in writing?

Critical thinking can help in planning your paper and making it more concise, but it's not obvious at first. We carefully pinpointed some the questions you should ask yourself when boosting critical thinking in writing:

• What information should be included?
• Which information resources should the author look to?
• What degree of technical knowledge should the report assume its audience has?
• What is the most effective way to show information?
• How should the report be organized?
• How should it be designed?
• What tone and level of language difficulty should the document have?

Usage of critical thinking comes down not only to the outline of your paper, it also begs the question: How can we use critical thinking solving problems in our writing's topic?

Let's say, you have a Powerpoint on how critical thinking can reduce poverty in the United States. You'll primarily have to define critical thinking for the viewers, as well as use a lot of critical thinking questions and synonyms to get them to be familiar with your methods and start the thinking process behind it.

How to develop critical thinking skills through essay writing , sponsored post.

• April 16, 2024

Have you ever thought why professors should only appraise students’ understanding of concepts taught in class through continuous assessment tests (CATs) and exams? Usually, such questions and related ones often transpire when you have a backlog of assignments and homework. For example, if you’re pursuing a science, technology, engineering, and mathematics (STEM) program, you might wonder why you should do courses or units in English 101 and/or 102, communication skills, and entrepreneurship to the extent of writing essays and research papers. Rather than helping you develop professional expertise such as writing cover letters and Resumes/ curriculum vitae, these disciplines contribute to you developing critical thinking. 

Nevertheless, how can essay writing help you rational reason for whatever you say, hear, or write if you struggle with doing non-technical assignments and research papers? In such a case, you don’t need to worry, especially with unlimited solutions on the Internet. For instance, you can google “professional essay writing service” to hire a specialist from EssayLib , who would be responsible for providing you with custom samples. You can use the materials you would have purchased not only to learn about logically putting down ideas on paper but also to make your college life easy. Besides the non-technical assistance you’ll receive, you can get reference materials in programming and calculations.  

4 ways essay writing will develop your critical thinking 

1. rely on scholarly sources .

If you read an essay completed with blogs and one that integrates journals, chapters of the book, and industrial reports, which of the two would be rich in ideas? Without a doubt, any scholar will appreciate the knowledge communicated in the latter. For example, when a journal presents the efficacy of a placebo drug on a patient with a life-threatening lifestyle disease like obesity, it will explain research on how it alleviates symptoms and corrects anatomical or physiological aberrants. However, such a study will indicate limitations on the medicine. For example, it might not be effective in pediatric patients. This information would provoke your critical thinking to the extent of including your verdict, like “an underlying rationale could be an underdeveloped immune system required to work with the drug.” Surprisingly, you can get an idea of conducting a scientific exploration upon noticing gaps and knowledge deficits.  

2. Refrain from unnecessary description  

When your professor informs you to argue “whether outsourcing of labor is ethically right or not,” how will you approach this question in your essay to boost your critical thinking? Even before answering this question, think about students who search for information on the Internet and start writing. In most cases, you’ll realize that they will begin describing how US companies that outsourced labor globally found them in unending litigation for violating established ethical policies. Whereas such an essay might have answered the question, it doesn’t contribute to knowledge progression. So, how can one avoid unnecessary descriptions of “whether outsourcing of labor is ethically right or not?” 

Ideally, you have a lot of angles to approach such a question. For example, you might rely on scholarly sources highlighting a US company outsourcing labor from specific countries. You can also identify a firm(s) retailing or wholesaling the same or substitute product as the one depending on foreign workforces. In this case, you can argue that outsourcing promotes unethical competition as it might lower the prices of its commodities. As a consequence, the one that doesn’t use foreign might shut down its operations even though it employs Americans. This simple explanation shows how opting to analyze rather than provide a general description stimulates critical thinking! 

3. Take advantage of the counterargument approach 

If you want to write an essay about “the implications of banning the use of polythene bags,” what comes to your mind? A significant proportion of students would focus on how this policy would contribute to improving the environment or reducing pollution. Of course, you’ll find a myriad of information supporting such an argument. For example, some sources would indicate that since these polythene papers don’t decompose, they tend to scatter when blown by the wind, creating an unpleasant environment. Of course, you’ll score with such points, but you won’t develop critical thinking skills. So, who can apply the counterargument approach? 

In one of the body paragraphs, you can state a controversial topic sentence, such as “The banning of polythene bags would reduce government revenue.” In this case, some can argue that the authorities spent a significant proportion of their budget cleaning the environment. However, you can raise a valid point of how the government collects corporate taxes and pays as you earn (PAYE) from companies and employees who produce polythene papers. What’s more, firms responsible for managing litters remunerate taxes. Such a counterargument approach indicates how you’ve developed critical thinking. 

4. Challenge authors’ arguments 

Whereas incorporating ideas from different sources boosts knowledge in your essay, it might be similar to intentional plagiarism, especially when you use a single source. In other words, it can be the same as paraphrasing your classmates’ work assignment and submitting it. So, who can make it differently? You should challenge the authors’ arguments. For example, if the source said that “the company made a dollar million profit in the ended financial year, making 5% increment from the previous year.” You can challenge this argument by saying that earnings per share remained the same even with the recorded upsurge in net income. This approach will increase your critical thinking on the view of profitability between internal and external stakeholders. 

In retrospect, you shouldn’t take essays as an opportunity to summarize previously written ideas. However, capitalize on this opportunity to expand your knowledge, challenge the existing status quo, and progress your knowledge in any discipline.
