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.
• textual examples and elaboration

Developing Strong Thesis Statements

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.

Reference management. Clean and simple.

How to write a thesis statement + examples

What is a thesis statement?

Is a thesis statement a question, how do you write a good thesis statement, how do i know if my thesis statement is good, examples of thesis statements, helpful resources on how to write a thesis statement, frequently asked questions about writing a thesis statement, related articles.

A thesis statement is the main argument of your paper or thesis.

The thesis statement is one of the most important elements of any piece of academic writing . It is a brief statement of your paper’s main argument. Essentially, you are stating what you will be writing about.

You can see your thesis statement as an answer to a question. While it also contains the question, it should really give an answer to the question with new information and not just restate or reiterate it.

Your thesis statement is part of your introduction. Learn more about how to write a good thesis introduction in our introduction guide .

A thesis statement is not a question. A statement must be arguable and provable through evidence and analysis. While your thesis might stem from a research question, it should be in the form of a statement.

Tip: A thesis statement is typically 1-2 sentences. For a longer project like a thesis, the statement may be several sentences or a paragraph.

A good thesis statement needs to do the following:

• Condense the main idea of your thesis into one or two sentences.
• Answer your project’s main research question.
• Clearly state your position in relation to the topic .
• Make an argument that requires support or evidence.

Once you have written down a thesis statement, check if it fulfills the following criteria:

• Your statement needs to be provable by evidence. As an argument, a thesis statement needs to be debatable.
• Your statement needs to be precise. Do not give away too much information in the thesis statement and do not load it with unnecessary information.
• Your statement cannot say that one solution is simply right or simply wrong as a matter of fact. You should draw upon verified facts to persuade the reader of your solution, but you cannot just declare something as right or wrong.

As previously mentioned, your thesis statement should answer a question.

If the question is:

What do you think the City of New York should do to reduce traffic congestion?

A good thesis statement restates the question and answers it:

In this paper, I will argue that the City of New York should focus on providing exclusive lanes for public transport and adaptive traffic signals to reduce traffic congestion by the year 2035.

Here is another example. If the question is:

How can we end poverty?

A good thesis statement should give more than one solution to the problem in question:

In this paper, I will argue that introducing universal basic income can help reduce poverty and positively impact the way we work.

• The Writing Center of the University of North Carolina has a list of questions to ask to see if your thesis is strong .

A thesis statement is part of the introduction of your paper. It is usually found in the first or second paragraph to let the reader know your research purpose from the beginning.

In general, a thesis statement should have one or two sentences. But the length really depends on the overall length of your project. Take a look at our guide about the length of thesis statements for more insight on this topic.

Here is a list of Thesis Statement Examples that will help you understand better how to write them.

Every good essay should include a thesis statement as part of its introduction, no matter the academic level. Of course, if you are a high school student you are not expected to have the same type of thesis as a PhD student.

How to Write a Strong Thesis Statement: 4 Steps + Examples

What’s Covered:

What is the purpose of a thesis statement, writing a good thesis statement: 4 steps, common pitfalls to avoid, where to get your essay edited for free.

When you set out to write an essay, there has to be some kind of point to it, right? Otherwise, your essay would just be a big jumble of word salad that makes absolutely no sense. An essay needs a central point that ties into everything else. That main point is called a thesis statement, and it’s the core of any essay or research paper.

You may hear about Master degree candidates writing a thesis, and that is an entire paper–not to be confused with the thesis statement, which is typically one sentence that contains your paper’s focus. 

Read on to learn more about thesis statements and how to write them. We’ve also included some solid examples for you to reference.

Typically the last sentence of your introductory paragraph, the thesis statement serves as the roadmap for your essay. When your reader gets to the thesis statement, they should have a clear outline of your main point, as well as the information you’ll be presenting in order to either prove or support your point. 

The thesis statement should not be confused for a topic sentence , which is the first sentence of every paragraph in your essay. If you need help writing topic sentences, numerous resources are available. Topic sentences should go along with your thesis statement, though.

Since the thesis statement is the most important sentence of your entire essay or paper, it’s imperative that you get this part right. Otherwise, your paper will not have a good flow and will seem disjointed. That’s why it’s vital not to rush through developing one. It’s a methodical process with steps that you need to follow in order to create the best thesis statement possible.

Step 1: Decide what kind of paper you’re writing

When you’re assigned an essay, there are several different types you may get. Argumentative essays are designed to get the reader to agree with you on a topic. Informative or expository essays present information to the reader. Analytical essays offer up a point and then expand on it by analyzing relevant information. Thesis statements can look and sound different based on the type of paper you’re writing. For example:

• Argumentative: The United States needs a viable third political party to decrease bipartisanship, increase options, and help reduce corruption in government.
• Informative: The Libertarian party has thrown off elections before by gaining enough support in states to get on the ballot and by taking away crucial votes from candidates.
• Analytical: An analysis of past presidential elections shows that while third party votes may have been the minority, they did affect the outcome of the elections in 2020, 2016, and beyond.

Step 2: Figure out what point you want to make

Once you know what type of paper you’re writing, you then need to figure out the point you want to make with your thesis statement, and subsequently, your paper. In other words, you need to decide to answer a question about something, such as:

• What impact did reality TV have on American society?
• How has the musical Hamilton affected perception of American history?
• Why do I want to major in [chosen major here]?

If you have an argumentative essay, then you will be writing about an opinion. To make it easier, you may want to choose an opinion that you feel passionate about so that you’re writing about something that interests you. For example, if you have an interest in preserving the environment, you may want to choose a topic that relates to that. 

If you’re writing your college essay and they ask why you want to attend that school, you may want to have a main point and back it up with information, something along the lines of:

“Attending Harvard University would benefit me both academically and professionally, as it would give me a strong knowledge base upon which to build my career, develop my network, and hopefully give me an advantage in my chosen field.”

Step 3: Determine what information you’ll use to back up your point

Once you have the point you want to make, you need to figure out how you plan to back it up throughout the rest of your essay. Without this information, it will be hard to either prove or argue the main point of your thesis statement. If you decide to write about the Hamilton example, you may decide to address any falsehoods that the writer put into the musical, such as:

“The musical Hamilton, while accurate in many ways, leaves out key parts of American history, presents a nationalist view of founding fathers, and downplays the racism of the times.”

Once you’ve written your initial working thesis statement, you’ll then need to get information to back that up. For example, the musical completely leaves out Benjamin Franklin, portrays the founding fathers in a nationalist way that is too complimentary, and shows Hamilton as a staunch abolitionist despite the fact that his family likely did own slaves. 

Step 4: Revise and refine your thesis statement before you start writing

Read through your thesis statement several times before you begin to compose your full essay. You need to make sure the statement is ironclad, since it is the foundation of the entire paper. Edit it or have a peer review it for you to make sure everything makes sense and that you feel like you can truly write a paper on the topic. Once you’ve done that, you can then begin writing your paper.

When writing a thesis statement, there are some common pitfalls you should avoid so that your paper can be as solid as possible. Make sure you always edit the thesis statement before you do anything else. You also want to ensure that the thesis statement is clear and concise. Don’t make your reader hunt for your point. Finally, put your thesis statement at the end of the first paragraph and have your introduction flow toward that statement. Your reader will expect to find your statement in its traditional spot.

If you’re having trouble getting started, or need some guidance on your essay, there are tools available that can help you.

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.

Make 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.

Identifies the relationships between the pieces of evidence that you are using to support your argument.

Content from this section originally by the University of Wisconsin - Madison's guide " Writing process and structure " by the Writing Center.

Characteristics Good Thesis Statements

Here are some characteristics of good thesis statements, with samples of good and poor ones. Note that the better examples substitute specific argumentative points for sweeping general statements; they indicate a theoretical basis and promise substantial support.

It makes a definite and limited assertion that needs to be explained and supported by further discussion

Non-specific example

Shakespeare was the world's greatest playwright.

Focused example

The success of the last scene in Midsummer Night's Dream comes from subtle linguistic and theatrical references to Elizabeth's position as queen.

It indicates the methodology of your argument

Emotional, vague example

This essay will show that the North American Free Trade Agreement was a disaster for the Canadian furniture industry

Worth attention example

Neither neo-protectionism nor post-industrial theory explains the steep reversal of fortune for the Canadian furniture industry in the period 1988-1994. Data of productivity, profits, and employment, however, can be closely correlated with provisions of the North American Free Trade Agreement that took effect in the same period. 

It shows awareness of difficulties and disagreements

Sweeping, vague example

Having an official policy on euthanasia just causes problems, as the Dutch example shows.

Suitable complex example

Dutch laws on euthanasia have been rightly praised for their attention to the principles of self-determination. Recent cases, however, show that they have not been able to deal adequately with issues involving technological intervention of unconscious patients. Hamarckian strategies can solve at least the question of assignation of rights. 

Content from this section originally by the University of Toronto's " Using Thesis Statements " written by Margaret Procter, Writing Support. 

Developing a Thesis Statement

The process of developing a thesis statement can be broken down into four steps:

Step 1 : Identify a topic

Step 2 : Derive a main point from the topic

Step 3 : Compose a draft thesis statement

Step 4 : Refine and polish the thesis

Developing a Thesis Statement 2

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.

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. 

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. The more material or knowledge you have, the more possibilities will be available for a strong argument

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 fulfill the assignment requirements . 

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 adolescents and women") or that simply are not important (i.e. "why I like ice cream").

Note : 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

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 favour 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. 

Compose a purpose statement

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 along. 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 . 

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. 

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 below may help you develop a temporary or "working" thesis statement.

Purpose statement

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

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.

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

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

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. 

As you write, you may discover evidence that does not fit your 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. You may have to revise your thesis to match the evidence and insights that you want to discuss. 

Refine and Polish the Thesis Statement

To get 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

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 describe 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 assignment.

Taking a Stance

Don't confuse your topic with your thesis. The assignment topic outlines the general scope of your project. Your thesis focuses your discussion of that topic. A thesis is a statement that takes a position or offers an interpretation of the subject. It is not simply a description or a statement of fact. 

Content from this section originally by Queen's University's " Developing a thesis statement ."

Some Myths About Thesis Statements

Myth #1: Every paper requires one

• Assignments that ask you to write a personal response or to explore a subject don't want you to pre-judge the issues. Essays of literary interpretation often want you to be aware of many effects rather than seeming to box yourself into one view of the text.

Myth #2: A thesis statement must come at the end of the first paragraph

• This is a natural position for a statement of focus, but it's not the only one. Very commonly in applied health sciences your thesis statement should appear very early on in your paper / article. This is because you need to be specific when writing for the applied health science and helps to structure your paper.

Myth #3: A thesis statement must be one sentence in length, no matter how many clauses it contains

• Clear writing is more important than rules like these. Use two or three sentences if you need them. A complex argument may require a whole tightly-knit paragraph to make its initial statement of position.

Myth #4: You can't start writing an essay until you have a perfect thesis statement

• It may be advisable to draft a hypothesis or tentative thesis statement near the start of a big project, but changing and refining a thesis is a main task of thinking your way through your ideas as you write a paper. Some essay projects need to explore the question in depth without being locked in before they can provide even a tentative answer.

Myth #5: A thesis statement must give three points of support

• It should indicate that the essay will explain and give evidence for its assertion, but points don't need to come in any specific order.

The main idea. The argument of an essay. The thesis. It’s a tricky thing to define “thesis” because theses come in all sorts of shapes and sizes. A thesis can be a sentence, two sentences, perhaps even an entire paragraph. Every thesis, though, regardless of where in an essay it appears, does a few important things:

• A thesis acts as a unifying idea for every piece of evidence in an essay.
• A thesis results from research in addition to the writer’s own beliefs or opinions.
• A thesis answers a specific question.

There are lots of ways to create a successful thesis because good theses come in all sorts of varieties. What all successful argumentative theses have in common, though, are the following characteristics:

• A good thesis statement is arguable. In other words, the writer’s claim might be challenged or opposed.
• A good thesis statement expresses one main idea, and that idea controls what is said, what is left out, and how the delivered evidence is organized.
• A good thesis statement is specific and insightful.
• A good thesis statement encourages discussion.
• A good thesis statement is supported by relevant evidence. Every paragraph should contribute to proving the thesis to be valid

Developing a Thesis

• Define the Rhetorical Situation: The key to developing an appropriate thesis is to begin by examining the rhetorical situation: What is the purpose of your essay (e.g., to inform, to persuade, to analyze)? To whom are you writing (e.g., classmates, members of a particular interest or age group)?
• Choose a Topic: Based on the purpose of and audience for your essay, what is an appropriate topic? Moreover, what is an appropriate topic that also interests you personally?
• Start with What You Know: What do you know about your topic? What have you heard on the news about your topic? Do you have personal experiences related to your topic? If so, what are they?
• Research What You Don’t Know: Start by searching the library databases (e.g., with Academic Search Premier or WorldCat). It’s best to begin by searching with your general topic and then refining your initial results. Gather a variety of sources and start reading. Some general reading on your topic will help you with the next step.
• Take a Position: Before you take a position, be sure you have done ample reading and you are aware of the various positions regarding your topic. Most issues have more nuances than basic understandings suggest. It is not enough to be “for” or “against” an issue. You must be able to support your position with evidence and logical reasoning, and research can help you in this regard.

Refining Your Thesis

After choosing a position, in forming reasoning for your decision, you must be clear and specific. You must be able to substantiate your claim using authoritative, credible, and relevant source material. Theses tend, in draft form, to begin as general and to become more specific as you do more research. Let’s look at how we might turn a weak thesis into a strong thesis.

Weak thesis:

On April 20, 2010, the explosion of the Deepwater Horizon oil platform caused the largest man-made disaster in U.S. history.

This thesis has a serious problem for two reasons: it doesn’t actually make an argument. It simply states an unproven fact: that the Deepwater Horizon oil spill is the largest man-made disaster in U.S. history. In order to be successful, a thesis must be arguable and supported by evidence. If we consider that a thesis must be a statement that reasonable people may disagree with and a position substantiated with credible evidence, this thesis is problematic because no one will disagree with the date the oil spill occurred and because the claim that the oil spill was the largest man-made disaster in U.S. history is unsubstantiated.

A still weak thesis:

Many people are to blame for the oil spill that resulted from the explosion of the Deepwater Horizon oil platform, which caused the largest man-made environmental disaster in U.S. history.

This thesis is better than the first because it does more than state a fact, but it is still problematic: it is not specific enough, and the claim that the Deepwater Horizon oil spill is the “largest man-made” disaster is still unsubstantiated. This thesis might, instead, attempt to answer the following questions: “Who is to blame for the Deepwater Horizon oil spill?” and “Why might it be considered the largest man-made environmental disaster in the U.S. history?” A successful thesis must be arguable and must answer a specific question.

A better thesis:

BP, President George W. Bush, President Barack Obama, Republicans in Congress, Democrats in Congress, and every citizen in the United States share the blame for the oil spill that resulted from the explosion of the Deepwater Horizon oil platform, which some consider the largest man-made environmental disaster in U.S. history, and in order to prevent another such disaster, Congress must develop better regulations, oil companies must enact better maintenance procedures, and Americans must decrease their dependence on oil.

This thesis is certainly more specific, but it’s trying to do too much. Proving that all parties mentioned are to blame for the Deepwater Horizon oil spill and that the solutions mentioned will prevent another oil disaster requires covering a lot of ground. A good thesis is arguable and specific, but also has one main idea. This thesis has too many main ideas.

An even better thesis:

Oil companies and the federal government share responsibility for the Gulf oil spill that resulted from the April 2010 Deepwater Horizon explosion.

This thesis works better than the previous versions because it’s arguable, specific, and focused on one main idea, but not so specific as to greatly limit discussion of the topic. From an essay based on such a thesis, readers will expect evidence that supports the claim that oil companies and the federal government hold joint responsibility for the Gulf oil spill.

Thesis Sentences

Characteristics of a strong thesis.

What makes a strong thesis in a college essay?

• 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.

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.

• The metaphor is extraordinarily useful even though the passage is annoying. Beyond the sexist language of the time, it displays condescension toward “fact-collectors” which reflects a general modernist tendency to elevate the abstract and denigrate the concrete. In reality, data-collection is a creative and demanding craft, arguably more important than theorizing. ↵

Unit 4: Fundamentals of Academic Essay Writing

23 Writing a Thesis Statement

Preview Questions:

• What is a thesis statement? How does a thesis statement help you when writing an essay?
• What are some characteristics of a good thesis statement?
• What are some common problems with thesis statements?
• Is it OK to change your thesis statement as you develop your essay?

A thesis statement is usually one sentence long (though you may see longer thesis statements in ESL 118). Think of a thesis statement as a type of “map” which tells the reader where your essay will “go” and what the reader can expect.

Characteristics of an effective thesis statement

• It includes the topic and focus. The thesis statement answers your research question.
• It includes an overview of your supporting points. These points are logically connected to your focus.
• It is not too long or too short; it provides sufficient information.
• A good thesis statement is written in formal, academic style, with appropriate and correct vocabulary and grammar. A good thesis statement is clear.

1 Topic and Focus

The thesis statement is a concise answer to your Research Question. It states the topic of your essay and expresses the focus.

• topic:   social media addiction
• focus:   why young people become addicted (causes)
• thesis:  Young people become addicted to social media because their brain chemistry puts them at risk for addiction, they need personal validation, and they are afraid of being left out.

2 Overview of Supporting Points

Your thesis statement should include a list of your supporting points. This overview shows the reader what you will write about and how those ideas will be organized. The example below illustrates the relationship between the rough outline , supporting points, and thesis statement.

• research question: What are the effects of smart phone addiction?
• focus: Effects
• Back and neck pain
• Shorter attention span
• Damage to eyesight from blue light
• Disrupted sleep
• Source of anxiety and stress
• thesis statement: Smart phone addiction can lead to an increase in anxiety and stress, a decrease in attention span, and physical problems like back and neck pain.

Notice that the writer did not use all five “answers” to their research question, but instead selected the three most important points. In addition, the writer has ordered the points so that there is a logical flow from what the reader perceives to be the most important point to less important point.

3 Provides sufficient information

Express the supporting points as single words or short phrases, but avoid expressing the supporting points as full sentences.

4 Uses academic style

In academic writing, a thesis statement is expressed using formal, academic writing style. Refer to Writing Academic Tips as a reminder of what this means.

5 Uses precise vocabulary

An effective thesis statement will use accurate, appropriate vocabulary. Choose the correct vocabulary to express your focus by consulting a dictionary and thesaurus. Use a corpus for checking collocations (like Skell Sketch Engine ).

6 Supporting points are grammatically parallel

The supporting points should be grammatically parallel. This means each point should be expressed using the same grammatical structure. See the examples below:

• Notice how each supporting point is expressed as a noun phrase.
• Notice how each supporting point is expressed as a verb + ing phrase.
• Notice how each supporting point is expressed as a short clause.

7 Should express a logical relationship among points whenever possible

When there are connections between points, determine the type of relationship between your points (e.g. cause-effect, sequence). Then include language to demonstrate the connections to your reader.

• To this extent, the most critical challenges that international students face include experiencing culture shock in and out of the classroom, overcoming language barriers in their daily life,  and dealing with stress and anxiety.

In the revision, the writer expresses a cause – effec t relationship:

• To this extent, the most critical challenges that international students face include experiencing culture shock in and out of the classroom and overcoming language barriers in their daily life,  consequently leading to stress and anxiety. 
• Therefore, U.S. colleges have strived to accommodate international students by offering professional and peer advising and mentoring, providing ample academic and activity resources,  and helping students meet new academic culture expectations.

In the revision, the writer expresses a cause – effect relationship:

• Therefore, U.S. colleges have strived to accommodate international students by offering professional and peer advising and mentoring, along with ample academic and activity resources,  ultimately helping students meet new academic culture expectations. 

Example 3: This writer has expressed a process along with a cause-effect relationship:

• Universities should combine synchronous and asynchronous techniques to optimize students’ online learning that offers accessible, interactive, and flexible education while keeping up with technology.

Example 4: This writer has expressed a cause – effec t relationship:

• Universities should blend synchronous and asynchronous learning, for the purpose of combining their advantages to offer greater flexibility and efficiency in student learning, ultimately leading to improved learning effectiveness.

Example 5: This writer has expressed a cause – effec t relationship:

• Online classes in higher education institutions should combine different modes of studying and be more affordable, both of which make education increasingly accessible and inclusive for students worldwide.

Problems with thesis statements

Keep the criteria above in mind to avoid these problems:

• A lack of focus
• A lack of supporting points
• Supporting points are not logically connected to the focus
• Contains too much information
• Use inappropriate, imprecise, or ungrammatical language
• Supporting points are not expressed using parallel (similar) grammar

A collocation consists of 2 or more words that are often used together. For example, we say,  "bake a cake," not "cook a cake." "Bake" and "cake" collocate; that is, they "go together."

Features of a successful thesis.

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

• A thesis must consist of a claim. Questions are not claims; nor are simple descriptions. A thesis is not a topic or theme, either. It is a contention —something to be argued.
• A thesis should not be obviously true or false. If a claim is obviously true, there is no need to argue for it; and if is it obviously false, there is no reason to argue for it, either. Rather, the claim should be plausible, but in need of argument and evidence to establish its veracity.
• A thesis should not be overly abstract or general. It must be specific enough to be arguable, that is, specific enough to support with the evidence available to you.
• A thesis should be original. It should not merely recapitulate another writer’s argument. However, this does not mean that a thesis cannot be based on or influenced by the arguments of other writers.
• There must be evidence available to support the claim made in the thesis.
• The claim must be of an appropriate scope such that it can be adequately argued within the length of the paper.
• A thesis should be clear. Remove as much ambiguity as possible from your thesis statement, and define any technical or ambiguous terms (e.g., “Durkheim-Boas tradition,” “reductionism”) that appear in your thesis or essay.
• A thesis should be concise. Generally, a thesis will be contained within a single sentence, although sometimes more complex theses are developed over two or three sentences.
• A thesis should be obvious to your reader. Often, a thesis statement begins with a phrase like “I will argue…,” “In this essay I will contend…,” etc. Theses are often stated in the first paragraph or in introductory paragraphs.

5.3 Thesis Statement

A thesis is simply an expression of the main idea of what you are writing about. The thesis will be determined by the kind or genre of paper you are asked to write, but even a summary assignment—a paper in which you summarize the ideas of another writer without adding your thoughts—must have a thesis. A thesis for a summary would be your expression of the main idea of the work you are summarizing. The presence of a thesis, and paragraphs to support that thesis, is what distinguishes a summary from a list.

A thesis statement  is a sentence that expresses the main claim of the entire essay. This means that every paragraph, every major point, every supporting detail, and every source must somehow relate to and support the thesis.

Essentially, when readers want to know what your point is, what they want to know is your thesis. And all college writing assignments expect you to make a point of some kind or another. This means that every one of your college essays should have a thesis. Some assignments emphasize argumentation more than others, so this need for a thesis might be less obvious to you in an essay that focuses more on reporting information, but it’s still there: your audience always expects you to make a point. An essay that has a good thesis has a good chance of succeeding. An essay that has a bad thesis, no matter what other strengths it may display, has a very poor chance of succeeding.

A common thesis statement is capable of being expressed in a single sentence. Much more information will be added to it in later sentences and paragraphs as support, but the primary idea itself will be focused and decisive enough to be stated in one sentence. However, there are times when a thesis statement should be multiple sentences, nevertheless, it should always be concise and clear.

A good thesis takes the form of a declarative sentence . This means that a good thesis is never a question. A question cannot state a point directly, but a thesis is a directly stated point, which means it won’t be a question but instead a possible answer to a question.

Three Characteristics of a Good Thesis

A good thesis statement has three characteristics:

• This means that it focuses on clearly defined ideas, often narrow enough to be discussed in a single essay. Within a thesis, referring to “sports” is not specific, but referring to “combat sports during the COVID-19 pandemic” is.
• This means that equally reasonable, intelligent, and educated readers could hold differing positions on the matter, and that the issues in the thesis can’t be answered with any kind of general certainty. “Bullying is bad” is not arguable for academic audiences, but what schools should do about bullying is. Keep in mind that arguable does not necessarily mean controversial. Academic arguments can be claims of analysis, observation, or other typically non-controversial modes. For example, a thesis claiming that “horror stories function through four primary motifs” is not controversial, but academically it is arguable. See more in the section Rhetoric and Argumentation.
• This means that it has some meaningful bearing on others and/or society. “I think Disney movies are terrible” is not significant, but exploring how “Disney movies have negatively affected the unrealistic worldview of children” is.

Common Errors: Bad Thesis Statements

It is possible for a thesis to be a single, declarative sentence yet still be bad. Often, this is because the thesis fails to display the three characteristics explained above. Here are some examples of bad thesis statements, along with brief explanations:

Bad Example 1: “Drugs have harmful effects on the community .”

Example 1 is bad because it is not specific. It does not indicate what drugs, specific effects, communities, or any other useful information.

Bad Example 2: “Racism should not be tolerated in school because it makes students feel alienated and harms the learning environment.”

Although Example 2 is specific and has good intentions, it is a bad thesis statement because it is not arguable. No one in a modern, rationally-minded audience would disagree and say that racism should be promoted in school. Therefore this thesis tells its readers what they already know, which makes it useless.

Bad Example 3: “Blue ink pens are better than black ink pens.”

Although Example 3 is specific and arguable, it is a bad thesis because it is not significant as is. Nobody cares, or at least it has no important effect on people’s lives or in society.

Good Thesis Statements

Now here are some good thesis statements with brief explanations.

“We should stop experimenting on animals and start experimenting on prisoners because the findings would be more accurate for humans and because prisoners aren’t innocent like animals are.”

This is highly arguable (you might disagree with it already), and that is a good thing: it is arguable while still being rationally able to defend itself (by offering at least two reasons as support). It is also good because it is very specific and because it is significant—it would matter whether America incorporates this idea.

“Divisions in America are getting worse because social media amplifies the voice of a minority of radicals, whom the majority of reasonable people are afraid to speak out against.”

This is a special type of thesis called a “causal analysis.” It argues why something is the way it is, and it is specific (it says exactly what and why), significant (it matters to many), and arguable (this might not be the reason, or at least not a main one—or it might be).

“The original iPhone was the most important invention in the past 20 years.”

Although this may be a bit challenging to support (because of the words “the most”), it is still a good thesis because it is arguable, it is specific (although the word “important” will have to be explained), and it would be significant if it proves to be a viable claim.

How to Build a Thesis

The way you build a thesis is to do the following in the order listed, making sure to use pre-writing strategies (whichever you prefer) to log your ideas each step of the way.

• Pick a broad subject that interests you.
• Pick some issue or controversy within that subject that interests you.
• Develop a guiding question about that issue or controversy, a question that is difficult or impossible for anyone to ever answer for certain.

(Warning: This is where lesser writers stop. They think this guiding question is what their essay is about—its thesis—but they are wrong because questions do not state points and cannot be argued. Do not stop here. Keep going until you have an actual thesis.)

• Make some sort of claim, comment, or point about that issue or controversy.

Improving the Thesis Statement

Early argument thesis statement.

People can’t seem to live without their phones, but spending that time online is detrimental.

• In bold we can see the writer’s opinion.

You’re already off to a good start: this thesis makes a claim, it demonstrates some knowledge or authority, and includes two sides to the issue. How can you make it better? Remember, you have to be able to write a paper in support of your thesis, so the more detailed, concrete, and developed your thesis is, the better. Here are a couple of suggestions for improving any thesis:

• Define your terms
• Develop the parts of your thesis so it answers as many who, what, when, where, how, and why questions as possible

Defining your terms

In your draft or working thesis above, are there any terms that would benefit from more definition? What do you mean by  people , for example? Can that word be replaced with  young people , teenagers, or young adults ? If you replaced  people  with these more specific terms, couldn’t you also then write your paper with more authority, as you are one of the people you’re writing about?

You might also define “can’t seem to live without,” which sounds good initially but is too general without explanation, with something more exact that appeals to your reader and can be supported with evidence or explained at greater length in your paragraphs: people “use their phones in the classrooms, at the dinner table, and even in restroom stalls.”

Teenagers and young adults seem to use their phones everywhere – in the classroom, at the dinner table, and even in restroom stalls , but spending that time online is detrimental.

• In bold we can see more definition and specificity in the terms.

Make sure your thesis statement answers questions

Your thesis is a snapshot or summary of your paper as a whole. Thus, you want your thesis to be something you can unfold or unpack or develop into a much longer work. And if your thesis makes a claim, that means it also answers a question. Thus, you want your thesis to answer or discuss the question as deeply and fully as possible. You can do this grammatically by adding prepositional phrases and “because” clauses that bring out the specifics of your thinking and tell your reader who, what, when, where, how, and/or why:

“Teenagers and young adults seem to use their phones everywhere—in the classroom, at the dinner table, even in restroom stalls— because they want to stay connected to their friends and peers at all times , but I think spending that much time online is detrimental  to their social skills and mental health .”

Notice that this thesis, while not substantially different from the draft or working thesis you began with, has been substantially revised to be more specific, supported, and authoritative. It lays out an organized argument for a convincing paper. Because it is so complete and specific it can be easily changed if you find research that contradicts your claim or if you change your mind about the topic as you write and reflect:

“Teenagers and young adults seem to use their phones everywhere—in the classroom, at the dinner table, even in restroom stalls—because they want to stay connected to their friends and peers at all times,  and research suggests that this connection has primarily positive psychological and emotional benefits .”

Teenagers and young adults seem to use their phones everywhere—in the classroom, at the dinner table, even in restroom stalls — because they want to stay connected to their friends and peers at all times , but spending that much time online is detrimental to their social skills and mental health.

• In italics  we see the “who” and the “when/where.”
• In bold we can see the potential counterargument.
• Underlined we see points the writer will support to prove their point and make their argument. These can be referred to as a “roadmap.”

Common Errors

Although constructing a thesis according to the above characteristics and steps will help you avoid the biggest problems, it’s still possible to run into a few common errors.

One such error is confusing an essay’s subject with a thesis , which is a claim or position about that subject. This is particularly problematic when students focus on arguing for the existence of what they believe to be facts. Some are easy enough to identify and revise, such as “America still allows the death penalty in some places.” This does not yet take a position on that subject, but a student could easily enough reach one once this error is noticed. Others create more complicated problems. Consider these examples: “Aliens exist.” Or: “Ghosts are real.” These might seem to fit the characteristics of good thesis statements above, but they do not. That is because these are merely subjects for the writer. The writer who has asserted these as facts in the world has, by doing so, not yet claimed them and has failed to take a position on them. Such a position might be what the writer thinks universities or research institutions should do with their budgets based on evidence of the existence of aliens, or ghosts. But taking such positions and supporting them often becomes quite complex and shaky, especially when directed toward academic audiences, which is why these kinds of “secret facts about the universe” subjects are too problematic for student writers to handle successfully. Some professors simply ban them to help students avoid inevitable trouble.

Another such error is confusing a self-referential announcement with a thesis . This kind of announcement often looks something like, “My essay will be about…,” or, “I think that…,” or, “For this assignment, I will tell you about…,” or something in the essay that similarly refers to itself as an essay. Sometimes the revision is simple: eliminate the needless phrase. Consider this example: “I think that the teaching of Shakespeare should be banned in American schools.” As it stands, it is not a thesis because it is a simple announcement about the writer, but simply removing “I think that” makes it a thesis, for it then makes an arguable, specific, and significant claim that would need to be supported. In other cases, needless self-referential announcements such as “my essay will be about” hide the fact that the student has just confused the subject with a thesis, as noted above. So, “My essay will be about the death penalty” is only a subject, not yet a thesis.

Another common error is confusing the role of personal opinion in a thesis . Some students come to believe that personal opinions are banned in English class essays, or college writing in general, but this is self-evidently wrong. The only way to make a thesis arguable is to take some opinion-based position on a matter. Opinions are therefore required in constructing a good thesis. But the simple statement of a personal opinion is rarely sufficient for a thesis; instead, it often becomes a mere statement of taste, which is neither arguable nor significant. “I love pineapple on pizza, no matter what anyone else says,” is just a statement of personal opinion, which means it can’t be arguable, nor is it significant. “I hate that Americans only get two options when voting for president” is just a personal opinion as it stands, but this one has the potential for a good thesis with just a little more revision.

One of the most difficult errors to face is confusing personal beliefs or convictions with claims . It is not necessary for college for student writers to personally believe all the ideas they explore in their essays, but this is hard for some students to comprehend or accept. Many students come to college having worked only on figuring out what they believe to be right and wrong, true and false, good and bad. That is fine up to a point, but it places the student in the prison of a singular perspective. One great aim of a true college education is, as Oscar Wilde put it, the ability to “play gracefully with ideas” rather than being stuck in “the violence of opinion merely.” So essays can serve as an opportunity to work through ideas that you have not necessarily given your heart, mind, and soul over to. This kind of serious play enriches you, makes you more perceptive, adaptable, and confident, and is indeed one main reason to bother writing at all. So avoid the temptation to write only about your convictions, or to fear any challenge to them. Instead, “play gracefully with ideas.”

These ideas will continue to be expanded upon as you read on and develop as an academic writer. However, it is important to build and practice a strong fondation.

Elements of a Thesis Statement

When writing an essay, you must focus on a main idea . This idea will stem from a topic you have chosen or been assigned or from a question your instructor has asked. It is not enough merely to discuss a general topic or answer with a yes or no: you will need to form an opinion and then articulate it into a controlling idea – the main idea you will build your thesis on.

A thesis is not the topic itself, but rather your interpretation of the question or subject. When an instructor presents you with a topic, ask, “What do you want to say about it?” Asking and answering this question is vital to forming a thesis that is specific.

A thesis is typically one sentence long and appears near the end of your introduction. It is specific and focuses on one to three points related to a main idea: you will work to prove these points in the body of your paper. Thus, the thesis forecasts the content of the essay and how you will organize your information. A thesis statement does not summarize an issue but rather helps to dissect it.

A Good Thesis Statement: Its Main Characteristics and Principles of Developing

Let us not waste your time talking about the significance of a good thesis statement. We just want to tell you that every reader is looking for it once he/she takes your paper and starts reading it.

If the reader cannot find a good thesis statement or finds it but it is ineffective, most probably he/she will quit reading further. This is why we suggest you learn some golden rules of making a good thesis statement right now!

A good thesis statement does the following:

• states what you are going to prove or believe in;
• distinguishes a well thought-over paper from a mere retelling of facts and events;
• helps you stay focused throughout the writing process.

The main characteristics of a good thesis statement

A good thesis statement should meet the following requirements:

• It should be clear and focused;
• It should be arguable;
• It should reflect your position on a topic.

Things to avoid in a good thesis statement

There are two things that should be avoided in a good thesis statement:

• Vague language, e.g. “issues”, “it seems”;
• The first person, e.g. “in my opinion”, “I suppose”.

How to make a good thesis statement

There are several questions that you should ask yourself if you want to make a good thesis statement:

• Will the reader ask questions like “Why?”, “How?”
• Can the reader ask “So what?” or “Who cares?”
• Can an expert say something like “No way”?
• Is it clear to the reader what major points you are going to make?

So, writing a thesis statement is not easy. However, it plays such an important role, thus, deserves your time and efforts.
