15 Examples of Bad Thesis Statements

When writing an essay, coming up with a strong thesis statement is crucial. A good thesis statement is concise, clear, and engaging and presents a strong argument to your readers. Conversely, a bad thesis statement is broad, unfocused, and unprovocative. It is important to be able to recognize a bad thesis statement so that you can avoid making the same mistakes in your own work. This article will provide 15 examples of bad thesis statements to serve as a warning. By the end, readers should be well-equipped to identify and avoid bad thesis statements.

Examples of bad thesis statements

“Trees provide oxygen.”

This thesis statement is ultimately too broad and therefore fails to present a unique argument. It does not provide adequate focus for the essay and does not present an interesting point for readers.

“Sports are important for all students in high school.”

This thesis statement fails to provide an adequate argument because it is too general. It does not address any particular school, students, or reasons why sports may be important.

“Humans should be able to choose the gender of their children.”

This thesis statement does not provide adequate focus for the essay. It does not present a clear stance for readers and does not take into account the ethical and moral implications of this sentiment.

“Too much technology is bad for our health.”

This thesis statement is overly broad and does not present a clear stance. It does not clearly determine which technologies are being referenced and does not demonstrate why they are bad for our health.

“Violence in the media causes violence in society.”

This thesis statement is overly broad and does not provide an adequate argument. It does not determine which media are being referenced and does not present evidence to support its claim.

“Video games make people anti-social.”

This thesis statement is overly broad and fails to provide evidence to support its claim. It does not reference any particular video games, nor does it discuss how video games can affect people differently.

“The government should invest more money in public transportation.”

This thesis statement fails to provide an adequate argument because it is too general. It does not discuss why this is important or how it would benefit society.

“ Schools should not allow cell phones on campus.”

This thesis statement is overly broad and fails to provide evidence to support its claim. It does not clarify which schools are being referenced, nor does it discuss all the potential benefits of cell phones on campus, such as emergency situations.

Top 6 Most Common Thesis Statement Mistakes

Writing a well-done thesis statement can often feel easier said than done. After all, this one sentence sets the tone for your entire paper and can make or break your assignment. To help with your next essay , we've put together a list of the most common thesis statement mistakes and tips to help you avoid them.

What is a Thesis Statement?

Just in case you need a refresher, here's a quick review:

A thesis statement, as defined by Dictionary.com , is: “a short statement, usually one sentence, that summarizes the main point or claim of an essay, research paper, etc., and is developed, supported, and explained in the text by means of examples and evidence.”

A thesis statement introduces your essay's main idea in the first paragraph of your assignment. It is the guiding factor that controls and organizes all other thoughts in your research paper.

How Do I Write a Thesis Statement?

It can take a long time to master the art of crafting a thesis statement. Luckily, there are some tools to help.

A good place to start is by checking out a thesis statement template. This will help ensure that you're including everything you're supposed to.

Here's a quick example:

You can also use an online thesis generator to organize your main idea and evidence. You enter the basic information about your argument and topic, and it helps you create a solid thesis statement.

It also helps to take time to explore some thesis statement examples (both good and bad) to clarify how to fix some of these common mistakes.

What are the Most Common Thesis Statement Mistakes?

Once you know the basics of how to write a thesis statement, there are certain mistakes to watch out for. Learning how to identify these common errors and understanding how to avoid them will help make your thesis statement a strong one.

1. The Statement is Unclear

Your reader needs to immediately understand your purpose. If it is vague or unclear, you've lost your audience from the start. Narrow down your focus and use straightforward language to state your main idea .

• Example thesis: The food in America is gross, unhealthy, and expensive, so we probably shouldn't be eating any of it.
• Improved thesis: Due to the obesity crisis in America, lawmakers should consider creating a plan to lower the prices of healthier foods so that everyone can afford to eat high-quality foods.

2. The Statement is Too Complicated

Making a statement that is too long or wordy generally confuses your reader. It also weakens the argument you are trying to make.

• Example thesis: Many athletes, such as those who play in colleges or for organizations like the NCAA, do not make any money, which is devastating because they deserve to make a substantial amount of money due to their efforts on the court and on the field and due to the fact that colleges earn a profit off of the sports that these athletes play.
• Improved thesis: NCAA athletes should receive compensation for their sports in college because they are generating revenue for universities and risking injury for themselves.

3. The Statement is Too Basic or Obvious

As you move up through school, your writing should mature as well. A successful thesis statement from junior high is not necessarily a strong thesis statement in high school or college. While being very basic and obvious in your younger writing might be fine, writing as an older student should be more precise and refined.

• Example thesis: In this paper, I will be discussing the importance of eating a healthy breakfast every day.
• Improved thesis: Eating a healthy breakfast is important to help your body function at its optimal level throughout the day.

4. The Statement has No Real Purpose

Your readers need to care about your topic in some way. Is this information helpful? Beneficial? Worth investigating? If not, choose a heartier topic that's worth discussing.

• Example thesis: I think these blue socks are the prettiest ones in the drawer.
• Improved thesis: Students should be allowed to express themselves as individuals by choosing any type of socks and shoes they want to wear to school.

5. The Statement Uses Poor Language Choices

Slang, abbreviations, and poor spelling have no place in a clear thesis statement. Use professional language to make your point.

• Example thesis: The best comedians should make you LOL 24-7.
• Improved thesis: To be a quality comedian, you must develop your craft in a way that inspires laughter and smiles at every performance.

6. The Statement Lacks Connection to the Rest of the Essay.

Even if you have a decent thesis statement, it will mean nothing if the rest of the essay strays from your main idea. Always connect your thoughts back to the thesis statement . The paper needs to be coherent and stay on target with your original argument.

Crafting a thorough thesis statement can feel like a difficult task, but it doesn't have to. If you are mindful of common mistakes that students make, you can avoid these errors and create a thesis statement that is clear, engaging, and purposeful.

On Thesis Statements

The thesis statement.

This is not an exhaustive list of bad thesis statements, but here're five kinds of problems I've seen most often. Notice that the last two, #4 and #5, are not necessarily incorrect or illegitimate thesis statements, but, rather, inappropriate for the purposes of this course. They may be useful forms for papers on different topics in other courses.

A thesis takes a position on an issue. It is different from a topic sentence in that a thesis statement is not neutral. It announces, in addition to the topic, the argument you want to make or the point you want to prove. This is your own opinion that you intend to back up. This is your reason and motivation for writing.

Bad Thesis 1

Bad Thesis 2 : This paper will consider the advantages and disadvantages of certain restrictions on free speech.

Better Thesis 1 : Stanley Fish's argument that free speech exists more as a political prize than as a legal reality ignores the fact that even as a political prize it still serves the social end of creating a general cultural atmosphere of tolerance that may ultimately promote free speech in our nation just as effectively as any binding law.

Better Thesis 2 : Even though there may be considerable advantages to restricting hate speech, the possibility of chilling open dialogue on crucial racial issues is too great and too high a price to pay.

A thesis should be as specific as possible, and it should be tailored to reflect the scope of the paper. It is not possible, for instance, to write about the history of English literature in a 5 page paper. In addition to choosing simply a smaller topic, strategies to narrow a thesis include specifying a method or perspective or delineating certain limits.

Bad Thesis 2 : The government has the right to limit free speech.

Better Thesis 1 : There should be no restrictions on the 1st amendment if those restrictions are intended merely to protect individuals from unspecified or otherwise unquantifiable or unverifiable "emotional distress."

Better Thesis 2 : The government has the right to limit free speech in cases of overtly racist or sexist language because our failure to address such abuses would effectively suggest that our society condones such ignorant and hateful views.

A thesis must be arguable. And in order for it to be arguable, it must present a view that someone might reasonably contest. Sometimes a thesis ultimately says, "we should be good," or "bad things are bad." Such thesis statements are tautological or so universally accepted that there is no need to prove the point.

Bad Thesis 2 : There are always alternatives to using racist speech.

Better Thesis 1 : If we can accept that emotional injuries can be just as painful as physical ones we should limit speech that may hurt people's feelings in ways similar to the way we limit speech that may lead directly to bodily harm.

Better Thesis 2 : The "fighting words" exception to free speech is not legitimate because it wrongly considers speech as an action.

A good argumentative thesis provides not only a position on an issue, but also suggests the structure of the paper. The thesis should allow the reader to imagine and anticipate the flow of the paper, in which a sequence of points logically prove the essay's main assertion. A list essay provides no such structure, so that different points and paragraphs appear arbitrary with no logical connection to one another.

Bad Thesis 2 : None of the arguments in favor of regulating pornography are persuasive.

Better Thesis 1 : Among the many reasons we need to limit hate speech the most compelling ones all refer to our history of discrimination and prejudice, and it is, ultimately, for the purpose of trying to repair our troubled racial society that we need hate speech legislation.

Better Thesis 2 : None of the arguments in favor of regulating pornography are persuasive because they all base their points on the unverifiable and questionable assumption that the producers of pornography necessarily harbor ill will specifically to women.

In an other course this would not be at all unacceptable, and, in fact, possibly even desirable. But in this kind of course, a thesis statement that makes a factual claim that can be verified only with scientific, sociological, psychological or other kind of experimental evidence is not appropriate. You need to construct a thesis that you are prepared to prove using the tools you have available, without having to consult the world's leading expert on the issue to provide you with a definitive judgment.

Bad Thesis 2 : Hate speech can cause emotional pain and suffering in victims just as intense as physical battery.

Better Thesis 1 : Whether or not the cultural concept of free speech bears any relation to the reality of 1st amendment legislation and jurisprudence, its continuing social function as a promoter of tolerance and intellectual exchange trumps the call for politicization (according to Fish's agenda) of the term.

Better Thesis 2 : The various arguments against the regulation of hate speech depend on the unspoken and unexamined assumption that emotional pain is either trivial.

Refining thesis statements, what makes for an effective thesis.

In an effort to make our handouts more accessible, we have begun converting our PDF handouts to web pages. Download this page as a PDF: Refining Thesis Statements Return to Writing Studio Handouts

An effective thesis should be argumentative and controversial (i.e., if you could make a plausible case against your thesis, it is probably an argument), something not immediately obvious which you can persuade a reader to believe through the evidence in the body of your paper.

A strong thesis statement answers a specific question and takes a distinct position on the topic, is focused, and allows the reader to anticipate the organization of the argument to follow.

A weak thesis statement is vague (identifies a topic but does not specify an argument), offers plot summary or is a statement of fact, is un-provable, or does not give the reader a sense of why the argument is important.

Look over the two example thesis statements below. Consider and name how each of the progressively refined versions matches the criteria offered above.

Example Thesis A

Version 1: Marge Simpson is important to the plot of The Simpsons.

Version 2:  Marge Simpson is important to The Simpsons because she fulfills a significant family role as a mother and housewife.

Version 3:  Marge Simpson is important to The Simpsons because she fulfills a significant family role as a teacher and caregiver to her husband and children.

Version 4:  While Marge Simpson may be a model caregiver for her family, she is a different sort of model for her audience.

Version 5:  Despite her role as a seemingly submissive housewife and mother, Marge Simpson comes to function for the audience of The Simpsons as a subversive force against “middle class” values.

Example Thesis B

Version 1:  Eating disorders are a significant problem among college-aged students.

Version 2:  Eating disorders are a significant problem among college-aged men because they negatively affect academic performance, socializing, and overall psychological well-being.

Version 3:  Eating disorders among college-aged men are overshadowed by a focus on eating disorders among college-aged women.

Version 4:  Eating disorders among college-aged men are overshadowed by a focus on eating disorders among college-aged women; people don’t notice this because an eating disorder is typically considered a women’s disease and is stigmatized as such.

Version 5: Lack of attention to eating disorders among college-aged men not only leaves this group of students untreated, but also exacerbates feelings of isolation associated with this disease.

How to Write a Thesis Statement–Examples

What is a thesis statement? A thesis statement summarizes the main idea of a paper or an essay. Similar to the statement of the problem in research, it prepares the reader for what is to come and ties together the evidence and examples that are presented and the arguments and claims that are made later. 

A good thesis statement can provoke thought, arouse interest, and is always followed up by exactly what it promises—if the focus or direction of your essay changes over time, you should go back to your statement and adapt it as well so that it clearly reflects what you are explaining or discussing. 

Where does the thesis statement go in my paper?

Your thesis statement should be placed near the end of your introduction—after you have given the reader some background and before you delve into the specific evidence or arguments that support your statement.

Can you give me a thesis statement template?

Depending on the type of essay you are writing, your thesis statement will look different. The important thing is that your statement is specific and clearly states the main idea you want to get across. In the following, we will discuss different types of statements, show you a simple 4-step process for writing an effective thesis statement, and finish off with some not-so-good and good thesis statement examples.

Types of Thesis Statements 

Depending on whether your paper is analytical, expository, or argumentative, your statement has a slightly different purpose. 

Analytical thesis statements

An analytical paper breaks down an issue or an idea into its components, evaluates the pieces, and presents an evaluation of this breakdown to the reader. Such papers can analyze art, music, literature, current or historical events, political ideas, or scientific research. An analytical thesis statement is therefore often the result of such an analysis of, for example, some literary work (“Heathcliff is meant to be seen as a hero rather than a horrible person”) or a process (“the main challenge recruiters face is the balance between selecting the best candidates and hiring them before they are snatched up by competitors”), or even the latest research (“starving yourself will increase your lifespan, according to science”). In the rest of the paper, you then need to explain how you did the analysis that led you to the stated result and how you arrived at your conclusion, by presenting data and evidence.

Expository thesis statements

An expository (explanatory) paper explains something to the audience, such as a historical development, a current phenomenon, or the effect of political intervention. A typical explanatory thesis statement is therefore often a “topic statement” rather than a claim or actual thesis. An expository essay could, for example, explain “where human rights came from and how they changed the world,” or “how students make career choices.” The rest of the paper then needs to present the reader with all the relevant information on the topic, covering all sides and aspects rather than one specific viewpoint.

Argumentative thesis statements

An argumentative paper makes a clear and potentially very subjective claim and follows up with a justification based on evidence. The claim could be an opinion, a policy proposal, an evaluation, or an interpretation. The goal of the argumentative paper is to convince the audience that the author’s claim is true. A thesis statement for such a paper could be that “every student should be required to take a gap year after high school to gain some life experience”, or that “vaccines should be mandatory”. Argumentative thesis statements can be bold, assertive, and one-sided—you have the rest of the paper to convince the reader that you have good reasons to think that way and that maybe they should think like that, too.

How to Write a Thesis Statement Step-by-Step 

If you are not quite sure how you get from a topic to a thesis statement, then follow this simple process—but make sure you know what type of essay you are supposed to write and adapt the steps to the kind of statement you need. 

First , you will have to select a topic . This might have been done for you already if you are writing an essay as part of a class. If not, then make sure you don’t start too general—narrow the subject down to a specific aspect that you can cover in an essay. 

Second , ask yourself a question about your topic, one that you are personally interested in or one that you think your readers might find relevant or interesting. Here, you have to consider whether you are going to explain something to the reader (expository essay) or if you want to put out your own, potentially controversial, opinion and then argue for it in the rest of your (argumentative) essay.

Third , answer the question you raised for yourself, based on the material you have already sifted through and are planning to present to the reader or the opinion you have already formed on the topic. If your opinion changes while working on your essay, which happens quite often, then make sure you come back to this process and adapt your statement.

Fourth and last, reword the answer to your question into a concise statement . You want the reader to know exactly what is coming, and you also want to make it sound as interesting as possible so that they decide to keep reading.

Let’s look at this example process to give you a better idea of how to get from your topic to your statement. Note that this is the development of a thesis statement for an argumentative essay .

• Choose a specific topic: Covid-19 vaccines 

Narrow it down to a specific aspect: opposition to Covid-19 vaccines

• Ask a question: Should vaccination against Covid-19 be mandatory?     
• Answer the question for yourself, by sorting through the available evidence/arguments:

Yes: vaccination protects other, more vulnerable people; vaccination reduces the spread of the disease; herd immunity will allow societies to go back to normal…

No: vaccines can have side-effects in some people; the vaccines have been developed too fast and there might be unknown risks; the government should stay out of personal decisions on people’s health…

• Form your opinion and reword it into your thesis statement that represents a very short summary of the key points you base your claim on:

While there is some hesitancy around vaccinations against Covid-19, most of the presented arguments revolve around unfounded fears and the individual freedom to make one’s own decisions. Since that freedom is offset by the benefits of mass vaccination, governments should make vaccines mandatory to help societies get back to normal.

This is a good argumentative thesis statement example because it does not just present a fact that everybody knows and agrees on, but a claim that is debatable and needs to be backed up by data and arguments, which you will do in the rest of your essay. You can introduce whatever evidence and arguments you deem necessary in the following—but make sure that all your points lead back to your core claim and support your opinion. This example also answers the question “how long should a thesis statement be?” One or two sentences are generally enough. If your statement is longer, make sure you are not using vague, empty expressions or more words than necessary .

Good and Bad Thesis Statement Examples

Not-so-good thesis statement : Everyone should get vaccinated against Covid-19.

Problem: The statement does not specify why that might be relevant or why people might not want to do it—this is too vague to spark anyone’s interest.

Good : Since the risks of the currently available Covid-19 vaccines are minimal and societal interests outweigh individual freedom, governments should make Covid-19 vaccination mandatory.

Not-so-good thesis statement : Binge drinking is bad for your health.

Problem: This is a very broad statement that everyone can agree on and nobody needs to read an article on. You need to specify why anyone would not think that way.

Good : Binge drinking has become a trend among college students. While some argue that it might be better for your health than regular consumption of low amounts of alcohol, science says otherwise.

Not-so-good thesis statement : Learning an instrument can develop a child’s cognitive abilities.

Problem: This is a very weak statement—”can” develop doesn’t tell us whether that is what happens in every child, what kind of effects of music education on cognition we can expect, and whether that has or should have any practical implications. 

Good thesis statement : Music education has many surprising benefits on children’s overall development, including effects on language acquisition, coordination, problem-solving, and even social skills.

You could now present all the evidence on the specific effects of music education on children’s specific abilities in the rest of your (expository) essay. You could also turn this into an argumentative essay, by adding your own opinion to your statement:

Good thesis statement : Considering the many surprising benefits that music education has on children’s overall development, every child should be given the opportunity to learn an instrument as part of their public school education.

Not-so-good thesis statement : Outer space exploration is a waste of money.

Problem: While this is a clear statement of your personal opinion that people could potentially disagree with (which is good for an argumentative thesis statement), it lacks context and does not really tell the reader what to expect from your essay.

Good thesis statement : Instead of wasting money on exploring outer space, people like Elon Musk should use their wealth to solve poverty, hunger, global warming, and other issues we are facing on this earth.

The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.
