This document provides guidance on writing effective thesis statements. It defines a thesis statement as a 1-3 sentence summary of the paper's central argument. The thesis should be placed early, ideally at the end of the introductory paragraph. It should be written in the third person without first-person pronouns like "I" to give the essay a stronger, more factual tone. Good thesis statements are focused, specific, clear and debatable rather than too general. They avoid simply comparing and contrasting without analysis.
