How to Write a Thesis Statement

If you’re wondering how to write a thesis statement, you’re most likely in the preparatory stages of writing an academic thesis: a substantial academic paper written on an original topic of research, usually presented as one of the final requirements for the Master’s or Ph.D. degree.

What Is a Thesis Statement?

It is important to note that an “academic thesis” should not be confused with a “thesis statement”. A thesis statement is:

  • “A basic argument” that clearly articulates what the Master’s or Doctoral thesis is expected to demonstrate
  • One of the initial building blocks to your immense writing project
  • A sentence or paragraph that summarizes the argument you plan to make in your thesis, as well as the supportive evidence you plan to use to back up that argument.
  • Provides a “roadmap” for the reader of where you plan to go with your thesis.

Most importantly, the thesis statement must convince the reader that the claim is important to your academic field, and that it is likely to be true based on the evidence provided.
Good Thesis Statements:

  • Make a knowledge claim that purports to offer a new approach or idea in a particular field, and to explain why it is new. The purpose of any academic thesis is to add to the existing pool of knowledge in a particular area, or to “fill in the gaps of knowledge.” As such, your knowledge claim should clearly state why the information/knowledge that you have to offer is new within your field, and should also convince the reader that your claim is likely to be true based on the evidence provided
  • Make an argumentative assertion that summarizes the conclusions you have reached about your topic after reviewing the literature. This assertion should be focused and specific enough to be “proven” within the boundaries of your paper. It should also identify the relationships between the pieces of evidence that you are providing.
  • Outline the scope, purpose and direction of your paper. After finishing your thesis statement, the reader should clearly know the essence of your intended project, and also the boundaries you intend to place on it. Your thesis statement should not make the reader expect more than you are prepared to present in your final document.

Keep in mind that your thesis topic should address an unresolved problem or knowledgegap in your subject area that needs to be explored and that concerns society as a whole. Your thesis topic should be unique in that it should add something new to the existing literature. Merely digging up answers that already exist does nothing to contribute to an academic or professional field of knowledge.

Simply put, a thesis topic should be based on new knowledge and new solutions to existing problems—not on simply churning up old answers. However, conducting research on questions that have already been answered is considered part of the literature review and is a useful exercise to find out if someone has already conducted research on your proposed research topic.
Types of Thesis Statements

There are three basic forms that your thesis statement can take:

  • Analytical: a statement that breaks down an idea piece by piece and analyzes and evaluates each individual part;
  • Expository: a statement that explains an idea or concept to an audience.
  • Argumentative: a statement that claims a position that is open to debate and justifies the truth of that position through concrete examples and evidence.

What Type of Thesis Statement Should You Use?

What type of approach you choose to take will depend upon the nature of your research. Analyzing why you are writing this thesis can provides important clues regarding the approach you should take. For example:

  • Are you proposing a new point of view, or agreeing someone else’s point of view with some disagreement or alternative interpretations?
  • Are you trying to make an existing point of view clearer or better in some way? Or are you criticizing or dismissing an existing point of view because of its inadequacy or irrelevance?
