Thesis Sentences

Characteristics of a strong thesis.

What makes a strong thesis in a college essay?

characteristics of an effective thesis

  • A strong thesis is non-obvious . High school teachers needed to make sure that you and all your classmates mastered the basic form of the academic essay. Thus, they  were mostly concerned that you had a clear and consistent thesis, even if it was something obvious such as “sustainability is important.” A thesis statement like that has a wide-enough scope to incorporate several supporting points and concurring evidence, enabling the writer to demonstrate his or her mastery of a basic essay format.  College instructors, though, fully expect you to produce something more developed.
  • A strong thesis is arguable . In everyday life, “arguable” is often used as a synonym for “doubtful.” For a thesis, though, “arguable” means that it’s worth arguing: it’s something with which a reasonable person might disagree. This arguability criterion dovetails with the non-obvious one: it shows that the author has deeply explored a problem and arrived at an argument that legitimately needs 3, 5, 10, or 20 pages to explain and justify. In that way, a good thesis sets an ambitious agenda for an essay. A thesis such as “sustainability is important” isn’t at all difficult to argue for, and the reader would have little intrinsic motivation to read the rest of the paper. However, an arguable thesis such as “sustainability policies will inevitably fail if they do not incorporate social justice,” brings up some healthy skepticism. Thus, the arguable thesis makes the reader want to keep reading.
  • A strong thesis is well specified . Some student writers fear that they’re being too obvious if they specify their thesis early in the essay; they think that a purposefully vague thesis might be more intriguing to the reader. However, consider movie trailers: they always include the most exciting and poignant moments from the film to attract an audience. In academic essays, too, a well specified thesis indicates that the author has thought rigorously about an issue and done thorough research, which makes the reader want to keep reading. Don’t just say that a particular policy is effective or fair; say what makes it is so. If you want to argue that a particular claim is dubious or incomplete, say why in your thesis.
  • A strong thesis is supportable . The angle in your thesis should be able to be supported with examples, details, facts, observations, and other types of evidence, including research as appropriate.
  • A strong thesis includes implications . Suppose your assignment is to write an essay about some aspect of the history of linen production and trade, a topic that may seem exceedingly arcane. And suppose you have constructed a well supported and creative argument that linen was so widely traded in the ancient Mediterranean that it actually served as a kind of currency. [1]   That’s a strong, insightful, arguable, well specified thesis. But which of these thesis statements do you find more engaging?
Version A: Linen served as a form of currency in the ancient Mediterranean world, connecting rival empires through circuits of trade. Version B: Linen served as a form of currency in the ancient Mediterranean world, connecting rival empires through circuits of trade. The economic role of linen raises important questions about how shifting environmental conditions can influence economic relationships and, by extension, political conflicts.

Strong thesis sentences have angles that are arguable, well-specified, and supportable. Not all topics and angles lend themselves to implications. However, if you’ve chosen a topic and created an angle that allows you to put your claims into a broader context, that additional context and its implications can create additional interest in an essay.

H ow do you produce a good, strong thesis? And how do you know when you’ve gotten there? Many instructors and writers find useful a metaphor based on this passage by Oliver Wendell Holmes, Sr. [2] :

There are one-story intellects, two-story intellects, and three-story intellects with skylights. All fact collectors who have no aim beyond their facts are one-story men. Two-story men compare, reason, generalize using the labor of fact collectors as their own. Three-story men idealize, imagine, predict—their best illumination comes from above the skylight.

Looking up from below the corner of a Japanese temple, so that three levels of red eaves, capped by black gutters, are arranged in a strong vertical point

The biggest benefit of the three-story metaphor is that it describes a process for building a thesis. To build the first story, you first have to get familiar with the complex, relevant facts surrounding the problem or question. You have to be able to describe the situation thoroughly and accurately. Then, with that first story built, you can layer on the second story by formulating the insightful, arguable point that animates the analysis. That’s often the most effortful part: brainstorming, elaborating and comparing alternative ideas, finalizing your point. With that specified, you can frame the third story by articulating why the point you make matters beyond its particular topic or case.

For example, imagine you have been assigned an essay about the impact of online learning in higher education. You would first construct an account of the origins and multiple forms of online learning and assess research findings about its use and effectiveness. If you’ve done that well, you’ll probably come up with a well considered opinion that wouldn’t be obvious to readers who haven’t looked at the issue in depth. Maybe you’ll want to argue that online  learning is a threat to the academic community. Or perhaps you’ll want to make the case that online learning opens up pathways to college degrees that traditional campus-based learning does not. In the course of developing your central, argumentative point, you’ll come to recognize its larger context; in this example, you may claim that online learning can serve to better integrate higher education with the rest of society, as online learners bring their educational and career experiences together.

To outline this example:

  • Basic Thesis/1st Story : Online learning is becoming more prevalent and takes many different forms. ( has a topic and angle, and is supportable, but the angle is broad. The angle would be more interesting if it offered an argument about an issue related to online learning.)
  • Strong Thesis/2nd Story : Strong thesis: While most observers see it as a  transformation  of higher education, online learning is better thought of an  extension  of higher education in that it reaches learners who aren’t disposed to participate in traditional campus-based education.( has a topic and angle, angle is arguable, supportable, and well-specified )
  • Stronger Thesis/3rd Story : Online learning appears to be a promising way to better integrate higher education with other institutions in society, as online learners integrate their educational experiences with the other realms of their life, promoting the freer flow of ideas between the academy and the rest of society. ( has a topic and angle, angle is arguable, supportable, and well-specified, angle contains implications that set the argument within a broader context )

Here’s one more example:

  • Basic Thesis/1st Story : Scientists disagree about the likely impact in the U.S. of the light brown apple moth (LBAM) , an agricultural pest native to Australia. ( has a topic and an angle, and the angle is supportable, but the angle is broad. The angle would be more interesting if it offered an argument about an issue related to the light brown apple moth.)
  • Strong Thesis/2nd Story : Research findings to date suggest that the decision to spray pheromones over the skies of several southern Californian counties to combat the light brown apple moth was poorly thought out. ( has a topic and angle, angle is arguable, supportable, and well-specified )
  • Stronger Thesis/3rd Story : Together, the scientific ambiguities and the controversial response strengthen the claim that industrial-style approaches to pest management are inherently unsustainable. ( has a topic and angle, angle is arguable, supportable, and well-specified, angle contains implications that set the argument within a broader context )

A thesis statement that stops at the first story isn’t usually considered a thesis. A two-story thesis is usually considered competent, though some two-story theses are more intriguing and ambitious than others. A thoughtfully crafted and well informed three-story thesis, which sets the angle in a broader context,  puts the author on a smooth path toward an interesting and insightful essay. As a beginning writer, know that you need to “build” at least two stories into your thesis; the third is something to attempt and strive for.

Here’s more information on how to write a strong thesis sentence, offering your specific assertion that is feasible to support, and setting that assertion within a broader context.

Thesis Characteristics

Whenever you are writing to explain something to your reader or to persuade your reader to agree with your opinion, there should be one complete sentence that expresses the main idea of your paper. That sentence is often called the thesis, or thesis statement. (Some other names it goes by are "the main idea" and "the controlling idea.") Based on everything you've read, and thought, and brainstormed, the thesis is not just your topic, but what you're saying about your topic. Another way to look at it is, once you've come up with the central question, or organizing question, of your essay, the thesis is an answer to that question. Remember, though, while you are still writing your paper, to consider what you have to be a "working thesis," one that may still be "adjusted." As you continue to write, read, and think about your topic, see if your working thesis still represents your opinion.

Handy reminders about the thesis (on this page): 

  • Where to put it
  • Put it as a statement
  • Don't go overboard
  • Focus further
  • Choose the right shape

Where to Put the Thesis

The thesis usually comes within the introductory paragraph, which prepares the reader to listen to your ideas, and before the body of the paper, which develops the thesis with reasons, explanations, and evidence or examples. In fact, if you examine a well-written thesis, you will find hidden in it the questions your reader will expect you to answer in the body. For example, if your thesis is "Cannibalism, if practiced tastefully, can be acceptable in extreme circumstances," the body of your essay will develop this idea by explaining HOW it can be practiced tastefully, WHY it would be acceptable, and WHAT you would consider extreme circumstances.

Put the Thesis as a Statement

Make sure your thesis is in the form of a statement, not a question. "Can we save the Amazon rain forest?" is an ear-catching question that might be useful in the introduction, but it doesn't express an opinion or perspective as the following statements do:

  • "We can save the Amazon rain forest by limiting tourist presence, boycotting goods made by companies that deplete the forest's resources, and generally educating people about the need to preserve the rain forest in order to preserve the earth's ecological systems."
  • "We cannot save the Amazon rain forest since the companies that deplete its resources in their manufacturing are so widely-spread throughout the world, so politically powerful in their respective countries, and so wealthy that they are able to fight the opposition fully."

Don't go Overboard!

Make sure your thesis expresses your true opinion and not an exaggerated version of it. Don't say "Computers are wonderful" or "Computers are terrible" if what you really believe is "Computers do more good than harm" or "Computers do more harm than good." Why commit yourself to an extreme opinion that you don't really believe in, and then look like you're contradicting yourself later on?

Focus Further

Make sure your thesis covers exactly the topic you want to talk about, no more and no less. "Drugs should not be legalized" is too large a thesis if all you want to talk about is marijuana. "Boxing should be outlawed" is too small a thesis if you also want to discuss wrestling and football. Bite off as much as you can chew thoroughly--then chew it!

Choose the Right Shape

Shape your thesis to fit the question you wish to answer. A thesis can come in many forms, including the following:

  • Simply stating an opinion: "Langston Hughes was a master stylist."
  • Indicating categories or reasons: "Langston Hughes was a master stylist because of his vivid imagery, surprising metaphors, and effective alliteration."
  • Showing two aspects of a topic and emphasizing one (in this sample, the 2nd topic in the sentence is emphasized): "While Langston Hughes was a master stylist, as a critic he had several blind spots."

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.

Writing an Effective Thesis Statement Podcast

Writing an effective thesis statement transcript.

Greetings everyone. This is Kurtis Clements with another effective writing podcast. In this episode, I am going to discuss how to write an effective thesis statement. One issue to keep in mind when you write is that your words need to stand on their own. It is your responsibility to express your thoughts in a way that others can understand. Think of it this way: You will not be around to explain to readers what you meant by a certain remark or to offer another example to illustrate a fuzzy point. Indeed, the words in your composition will have to communicate meaning without your presence. What you do not want to have happen is for your audience to reach the end of a piece of your written communication and say, “So what? What’s the point?”

The “so what” of a piece of writing is the specific point the piece makes, what the writing says about its subject. The “so what” is what the writing adds up to. It is the meaning found in the writing. The “so what” of an informative essay may be Boston has a lot to offer young children. The “so what” of a business memo may be profits have exceeded expectations.

No matter the type of composition, the piece of writing must communicate meaning, not to the writer, but, rather, to an audience. The meaning found in a piece of writing, the “so what,” is the most important aspect of any piece of writing, for what good would a piece of writing be if it did not add up to something, if it did not say something to an audience? When you are working on a composition, you will need to think about what you are trying to say so that you are in a position to make sure that what you are trying to communicate is, in fact, communicated.

I know what you’re thinking: What’s all this have to do with a thesis statement? The answer: everything! Let me explain.

Every composition needs to make a clear point about its topic—otherwise, what purpose would the writing serve? One way to ensure that readers will follow along in the development of an essay is by including a written out thesis statement (more on this in just a moment). The word thesis comes from a Greek word that means “proposition” or “position.” In an essay, the thesis establishes the writer’s position, the main idea of the paper, what the writer claims to be true or important about the topic. A thesis helps readers understand the direction the essay is heading and it connects body paragraphs to a controlling idea so that the essay comes together as a unified whole.

Most thesis statements are expressed in a single declarative sentence, but depending on a number of factors such as the scope and complexity of the topic or the writer’s approach in discussing it, the thesis may require more than one sentence, but this is the exception rather than the rule. In most academic writing, the thesis will appear near or at the end of the introduction and announce to readers exactly what the body paragraphs that follow will discuss. In some writing, especially personal writing, a written-out thesis may not be necessary, but regardless the focus of the paper still needs to be clear. So, whether the thesis is written out verbatim or not, the thesis of the paper—what it will discuss—still needs to be clear.

Constructing a thesis statement will take time; in fact, like writing itself, developing a thesis is a process, so you will need to be patient and be willing to revise as necessary. A good thesis comes about the more you explore your topic whether that exploration is the result of exploratory writing like freewriting or research or long walks in which you think and think and think.

As you explore your thinking, your ideas will get clearer and clearer. Again, a thesis statement evolves over time. Begin with a working thesis—your tentative ideas about a topic—and be willing to modify the statement depending on what you discover about your topic and how your thinking changes over time. Indeed, many writers find themselves in jams because they are unwilling to deviate from their original thesis and are bent on trying to support ideas that are unrealistic, perhaps even impossible.

Still worse, some writers try to force the content to fit the idea expressed in the thesis. This won’t work. In fact, some writers approach their work so that the thesis emerges out of the writing. That’s right! Some writers don’t start with a thesis—working or otherwise—and, instead, explore their thinking in writing as a way to discover what it is they have to say about a topic. The fabulous Donald Murray, a journalist and famous writer about the process of writing, worked this way. And other writers work this way, too. And of course, many writers do not work this way and the truth is the actual process you use to develop a thesis does not matter so long as the end result is successful.

As you approach drafting a thesis, make sure you keep your purpose for writing in mind. Will you be informing? Persuading? Entertaining? Complaining? Whatever the case, you will want that purpose to be apparent from the construction of the thesis.

One good way to come up with ideas that you can use to construct a working thesis is to explore your thoughts. What do you already know about the topic? Use freewriting (or some other exploratory writing method such as brainstorming) to capture what you already know and think about the topic. Roll up your sleeves and spend 10, 15, or more minutes just writing. Write about what interests you about the topic and what you might like to know. Explore freely what is bouncing around inside your head and do not be afraid to follow your thinking wherever it takes you. Writing is an act of discovery, and you might stumble upon an interesting angle to pursue if you give yourself permission to explore. After you’ve written for a period of time, look over your writing and see if any dominant idea emerges or if some of the writing suggests a direction worth thinking about more. In a perfect world, the freewriting will produce enough of your ideas that you can almost see the beginning of a thesis.

Another good approach to producing a thesis is to conduct some research. Some assignments may not benefit from this tip, but many—even those that don’t specifically require research—will. To this end, peruse the library whether you do so physically or virtually. Poke and read around about your topic, following the discussion here and there depending on what interests you. Take some notes as you see fit.

You could also ask questions about what you wonder or would like to know about your topic. Do big-box stores such as Home Depot and Wal-Mart have an impact on local economies? What are the benefits of a vegan lifestyle? How costly are green energy sources? What steps should individuals take to safeguard against identity fraud? Avoid yes/no type questions and research accordingly. A good research question can lend itself to the development of a working thesis in that the “answer” can serve as a starting point.

So what are the characteristics of an effective thesis statement?

An effective thesis statement establishes one major idea. If a thesis introduces more than one idea, the paper will not have a tight focus. Most papers you will write will be relatively short and do not have room to discuss more than one major idea. Pay particular attention to your thesis statement if it includes the word “and” as this connecting word often joins new ideas. Note how the following thesis has more than one main idea: Healthcare reform must be addressed because so many Americans are uninsured or without adequate coverage, and politicians must work together to ensure new legislation is passed. In this example, the word “and” establishes an additional main idea and so the thesis lacks a clearly defined focus. To improve upon the thesis, the thesis would need to be streamlined and focus on one main idea. For example, a better thesis might be Politicians must work together to reform healthcare because too many Americans are without sufficient coverage.

An effective thesis statement is limited in scope. The thesis should limit the extent of the discussion to something manageable given the assignment—neither too broad nor too narrow. The thesis should establish a focus that is realistic and suitable for a substantive discussion of the main idea. Taking a stand on capital punishment, for example, is not realistic for a short research paper let alone an entire book—the topic is too broad. However, limiting the focus by narrowing the scope may work. You could argue that capital punishment does not reduce the crime rate or that lethal injection is the most humane form of capital punishment. In this way, the focus is something that realistically could be addressed in the paper.

An effective thesis statement clearly states the writer’s position. The thesis should state precisely and specifically what the paper will discuss. After reading the thesis, readers should know exactly what to expect. Avoid language that is too general, abstract, or otherwise confusing. If your thesis does not clearly establish your main idea, readers may have a difficult time following the development of the body paragraphs that follow. Here is an example of a thesis statement that is vague: Television violence is an issue that many face. Based on this thesis, do you understand what the writer is going to explore in the paper? Sure, television violence, but beyond that general subject, do you have any clear sense of what the writer will be exploring? Not at all! This thesis lacks the specificity it needs to orient readers appropriately so that they know what to expect in the discussion.

An effective thesis statement requires supporting evidence. The thesis expresses an idea that moves beyond a statement of fact and requires supporting content to “prove” the main idea. For example, a thesis that proclaims Barack Obama is the first African-American to be elected president of the United States would not be very good as it states a widely known fact. A better thesis might proclaim this: Barack Obama’s election as president of the United States marked a seminal moment in American politics. The revised thesis moves beyond simply stating a fact and, instead, presents a main idea that would require evidence to support.

There are two basic approaches to composing a thesis—forecasting the main points by embedding them in the thesis (an approach commonly referred to as the three-point thesis) or not including the main points in the thesis. Your approach will depend on the topic you are addressing as well as any particular requirements of the assignment.

A three-point thesis states the main idea of the essay and includes three key points as support. Take a look at the following thesis: Banning cigarette smoking in public places is an effective intervention to improve the public’s health by helping to reduce the dangers of second-hand smoke on non-smokers, encouraging current smokers to quit, and reducing healthcare costs. In this example, the main idea—the position the writer takes relative to the topic—is Banning cigarette smoking in public places is an effective intervention to improve the public’s health. This part of the thesis states what the writer claims to be true about the topic. How will the writer support this view? In this case, the thesis includes three telegraphed key points—by helping to reduce the dangers of second-hand smoke on non-smokers, encouraging current smokers to quit, and reducing healthcare costs.

The three-point thesis is the blueprint of the essay in that it not only establishes the main idea, but it also fleshes out the key points to that readers can anticipate a basic structure of the essay. Readers would expect each forecasted point to be discussed in the order presented—that is, the first section will discuss the first key point, the next section the second, and so on.

Another approach to composing a thesis is to state the main idea minus the key points. Using the example above, the thesis would read: Banning cigarette smoking in public places is an effective intervention to improve the public’s health. With this approach, the key points are not included in the thesis, yet the focus and direction are clear. Readers may not know the exact key points, but they understand the writer’s position on the topic and can anticipate the likely discussion that will follow. In this case, since the main idea states the view that banning smoking in public is an effective intervention to improve public health, it is logical to expect key points that address how this is so.

Please keep in mind that writing a good thesis is a process and a process requires time. While some folks might be able to come up with a humdinger of a thesis from the get-go that is not the norm. To this end, give yourself time to explore your topic and don’t be impatient. Draft a working thesis and revise as necessary. I hope you find this podcast helpful.

Thanks, everyone. Happy writing!

After your prewriting activities-- such as assignment analysis and outlining--you should be ready to take the next step: writing a thesis statement. Although some of your assignments will provide a focus for you, it is still important for your college career and especially for your professional career to be able to state a satisfactory controlling idea or thesis that unifies your thoughts and materials for the reader.

Characteristics of an Effective Thesis

A thesis consists of two main parts: your overall topic and your position on that topic. Here are some example thesis statements that combine topic and position:

Sample Thesis Statements

Importance of tone.

Tone is established in the wording of your thesis, which should match the characteristics of your audience. For example, if you are a concerned citizen proposing a new law to your city's board of supervisors about drunk driving, you would not want to write this:

“It’s time to get the filthy drunks off the street and from behind the wheel: I demand that you pass a mandatory five-year license suspension for every drunk who gets caught driving. Do unto them before they do unto us!”

However, if you’re speaking at a concerned citizen’s meeting and you’re trying to rally voter support, such emotional language could help motivate your audience.

Using Your Thesis to Map Your Paper for the Reader

In academic writing, the thesis statement is often used to signal the paper's overall structure to the reader. An effective thesis allows the reader to predict what will be encountered in the support paragraphs. Here are some examples:

Use the Thesis to Map

Three potential problems to avoid.

Because your thesis is the hub of your essay, it has to be strong and effective. Here are three common pitfalls to avoid:

1. Don’t confuse an announcement with a thesis.

In an announcement, the writer declares personal intentions about the paper instead stating a thesis with clear point of view or position:

Write a Thesis, Not an Announcement

 2. a statement of fact does not provide a point of view and is not a thesis..

An introduction needs a strong, clear position statement. Without one, it will be hard for you to develop your paper with relevant arguments and evidence.

Don't Confuse a Fact with a Thesis

3. avoid overly broad thesis statements.

Broad statements contain vague, general terms that do not provide a clear focus for the essay.

Use the Thesis to Provide Focus

Practice writing an effective thesis.

OK. Time to write a thesis for your paper. What is your topic? What is your position on that topic? State both clearly in a thesis sentence that helps to map your response for the reader.

Thesis Statements

A thesis statement is a sentence (sometimes more than one sentence) in the introduction that tells the reader the following information:

  • What the topic of the paper is
  • How the writer intends to discuss that topic
  •  It gives a blueprint for how the essay will be structured
  •  How the writer intends to prove or demonstrate his or her main points.

Think of your paper as a human body, and your thesis statement as the spinal cord. Without it, there is no structure.

For you as the writer, the thesis statement:

Develops through the interrelationship of thinking, reading, and writing;

Limits your research by providing you with one controlling main idea that intrigues you;

Narrows your writing to one specific claim that you can develop or prove;

Organizes your ideas so you know the important points you want to make in your paper; and

Clarifies your writing by keeping you on target to fulfill your proposed purpose.

For your readers, the thesis statement:

 Identifies the main point and sub-points of your essay clearly and quickly;

Functions as a road map so your readers can easily follow your ideas; and

Gives satisfaction at the conclusion of the paper when your readers discover you have fulfilled your promise by proving or developing your main point.

Characteristics of Effective Thesis Statements

An effective thesis statement must be  factual and narrow.

An effective thesis statement prepares readers for facts and details, but it cannot itself be a fact. It must always be an inference that demands proof or further development. These proofs come from the literature. 

UNT Dallas campus has two buildings.

Not factual enough: The UNT Dallas campus is the perfect size.

Just Right:  While some might see small universities as a disadvantage, the small campus of UNT Dallas holds many advantages for students, including a close-knit campus community, smaller class sizes, and better support from professors.

2. Narrow Topic

A good thesis should be narrow, and not too broad or too vague. If the topic is too broad, you won’t be able to cover the entire topic in your paper.  If it’s too narrow, you might not be able to find research, and your paper probably won’t be long enough. 

Too Broad: College students have a lot of responsibilities.

Too Narrow: Student workers in the Learning Commons at UNT Dallas have many responsibilities in their course work and tutoring. 

Just Right: College students who are financially independent have many responsibilities as they must maintain good grades, pay living expenses, and balance work and school.

Remember, a thesis statement is not: 

  • Instead , you should argue, based on facts and literature, why or why not NASA should receive more funding.  
  • Ask yourself--can I find anything in literature to prove this point, or is this MY opinion? 
  • Instead, you should argue why or why not people like chocolate OR why or why not chocolate is healthy for you based on facts and literature findings. 
  • Similar to the subjective opinion, ask yourself is this statement is based on facts and literature findings or if this is YOUR opinion. Although it is ok to have your own opinion, professors usually do not like to read articles about beliefs (students have been writing about these for years and years). 
  • Instead, you could discuss theories about politics or religions and use literature to prove or disprove those theories.
  • This is too factual (the Himalayas WERE formed from a collision of tectonic plates), and there is nothing to discuss because this IS a fact in itself. 
  • Instead, you could compare and contrast the tectonic plate formation of different mountains. 

Examples of Thesis Statements

A thesis statement f or a 5 paragraph essay conta ins three parts:.

1. A Topic: the main idea of the essay

2. The Controlling Idea: what you want to say about the topic

3. The subtopics: usually 3 examples/reasons you will discuss in your paper

Here is an example  of a thesis statement.

Ex: Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.

The main topic explores the idea that regularly vsiting the writing center will help you become the best writer on the planet, and the subtopics further expand this opinion with three distinct examples: 1) tutors, 2) technology, and 3) the handouts.

Outline Example

The paper should be organized around the subtopics.  For example, for the thesis written above, the writer would write one body paragraph about the tutors, one about technology, and one about the handouts. 

Here is a sample essay outline based on this thesis:

  • Introduce the topic of tutoring
  • Thesis (last sentence of intro): Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.
  • topic sentence
  • Restate thesis
  • Concluding remarks

For further assistance with the structure, see our handouts on Introductions and Conclusions and Topic Sentences.

A thesis statement for a LONG ESSAY contains two parts: A Topic: the main idea of the essay The Controlling Idea: what you want to say about the topic 

Throughout the paper, your thesis promises your readers that you will prove specific facts or develop certain ideas ; therefore, every paragraph, sentence, and word in your paper must relate to this controlling idea.

Here are some examples of thesis statements.

  • Baseball, once a national pastime and even an addiction, has lost its popularity because of the new interest in more violent sports.
  • Since the space program has yet to provide the American people with any substantial, practical returns, it is a waste of money and should be dissolved.
  • To stop the alarming rise in the number of violent crimes committed every year, our courts must hand out tougher sentences.
  • Detective stories appeal to the basic human desire for thrills.
  • Hemingway's war stories helped to create a new prose style.
  • Bronte utilizes light and fire to symbolize the emotional expressions of the characters.

Here is a suggested outline for a long essay and how that would look in terms of your thesis statement, topic, and controlling ideas:

  • Introduce the novel Jane Eyre and the topic of symbolism
  • Thesis (last sentence of intro): Bronte utilizes light and fire to symbolize the emotional expressions of the characters.

Tips for writing an effective thesis statement.

This handout is available for download in DOCX format and PDF format .

Thesis statements are essentially the driving force and backbone of an academic essay. Without a thesis statement, your essay will lack a cohesive argument and will read more like a list of statistics, quotations or connecting ideas. Before completing your thesis statement, ask yourself:

  • Is your essay’s major claim complex? Is it insightful? Is it surprising or unexpected?
  • Does your thesis respond to a question, tension or problem?
  • Is your thesis stated clearly at the outset and does it evolve and develop throughout the paper?
  • Does your thesis statement have a clear motive?

Effective thesis statements directly and boldly articulate a complex, arguable or surprising argument (or arguments) of your own which will need to develop throughout the essay. They should be intelligent, well thought-out responses to a question or problem your essay will address.

Weak Thesis Statements Often:

Make no claim.

  • Example: This paper will examine the similarities and differences between two articles.
  • Possible Solution: Put the articles in conversation with one another and raise specific issues they agree or disagree about.

Are Obviously True or Statements of Fact

  • Example: Tourists are often out of place in other cultures.
  • Possible Solution: Make an assertion your reader can argue with.

Restate Conventional Wisdom or Clichés

  • Example: We shouldn’t judge others because it’s the inside that counts.
  • Possible Solution: Seek to complicate your thesis by anticipating counterarguments; try offering something new to the cliché.

Offer Personal Conviction as the Basis for the Argument

  • Example: Clearly, Kincaid is being one-sided.
  • Possible Solution: Maintain some distance from your subject. Do not merely assume your idea is an objective or obvious truth.

Make Overly Broad Claims

  • Example: Limerick shows her knowledge about the West.
  • Possible Solution: Convert broad, generic categories into more specific, complex assertions. Find ways to bring out the complexity of your argument.

More Questions for Constructing Strong Thesis Statements:

A strong thesis statement is often not created all at once but will rather go through stages of revision. A thesis statement in its early form is called a “working thesis.” While honing and tightening your working thesis, ask yourself these questions:

  • Does my thesis pass the “So what?” test? If a reader’s first response is likely to be “So what?” then you need to clarify it or connect it to some larger issue via a compelling motive.
  • Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful?”
  • Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to fit together, one of them has to change. It’s perfectly okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary!
  • Does my thesis answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question.
  • Does my thesis statement teach my reader something they did not already know? Am I bringing a new idea or perspective to the table on the issue or problem raised? Am I happy with what my thesis statement is saying?

Points to Remember:

  • The thesis statement usually appears at the end of the first paragraph of a paper.
  • A thesis is not the answer to a math problem; it is not supposed to be “correct.” Your thesis should be designed to persuade the reader that your point of view is valid and worthy of consideration.
  • Make sure your thesis is your own argument and not simply the argument that you think your instructor or one of your sources would approve of.
  • A thesis statement will never be perfect, because it is an attempt to encapsulate everything that will happen in your argument. Since it takes a whole paper to do that, your thesis will always lack something. Accept this and make it the best it can be regardless!

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

  • Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
  • Makes a promise to the reader about the scope, purpose, and direction of your paper.
  • Is focused and specific enough to be “proven” within the boundaries of your paper.
  • Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
  • Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

  • Franco first tried to negotiate with the Axis
  • Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.
  • The simile compares Simoisius to a tree, which is a peaceful, natural image.
  • The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

  • This paper will look at modern language to see if it reflects male dominance or female oppression.
  • I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

  • nature = peaceful
  • war matériel = violent (competes with 1?)
  • need for time and space to mourn the dead
  • war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

  • although most readers of _______ have argued that _______, closer examination shows that _______.
  • _______ uses _______ and _____ to prove that ________.
  • phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

  • Ask if your draft thesis addresses the assignment
  • Question each part of your draft thesis
  • Clarify vague phrases and assertions
  • Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

  • Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.
Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.
Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.
While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.
While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

  • Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
  • As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
  • Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
  • Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

  • tells the reader how you will interpret the significance of the subject matter under discussion.
  • is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
  • directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
  • makes a claim that others might dispute.
  • is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

  • Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
  • Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
  • Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
  • Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
  • Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
  • Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

  • Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
  • Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
  • Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
  • Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
  • Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

  • Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.
  • Do I answer the question? Yes!
  • Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
  • Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
  • Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
  • Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.
