This document provides guidance on developing an argumentative thesis statement for a research paper. It explains that an argumentative paper makes a claim and provides evidence to support that claim. The goal is to convince the audience that the claim is true. A good thesis statement is specific, clear, takes a stance, and appears at the end of the first paragraph. It should not be a question, list, or vague. An effective thesis must also be debatable and narrow in scope. Different types of claims include claims of fact, claims of cause and effect, claims about values, and claims about solutions or policies.
