How to Choose the Right Topic

Step 1. Turn each topic into a research question beginning with how, why, or to what extent.

Step 2. Search two academic databases and confirm at least eight relevant sources exist.

Step 3. Narrow by population, geography, or time period until the scope fits your page count.

Step 4. Draft a working thesis and confirm it can be supported or refuted with your sources.

Step 5. Build an annotated bibliography before drafting the paper.

Common Mistakes to Avoid

• Picking a topic so broad you cannot cover it in the assigned page count


• Choosing a subject with no credible, peer-reviewed sources available


• Restating an argument without adding your own analysis or evidence


• Ignoring your instructor's rubric, required citation style, or page limits


• Leaving topic selection until the night before the deadline

Frequently Asked Questions

How many sources does a research paper need?

A 10-page undergraduate paper typically cites 10–15 sources, the majority peer-reviewed. Always check the rubric for a minimum.

How do I narrow a broad topic?

Add constraints: a population, a geographic region, a time window, or a single outcome variable. "Social media and teens" becomes "Instagram use and body image among US teen girls, 2018–2024".

Can I use news articles as sources?

Use them for context or current events, but the core of your argument should rest on peer-reviewed research and primary data.
