Quick Reference: Topic Ideas by Format
How to Pick the Perfect Informal Topic: A Step-by-Step Framework
Step 1: Start With What Genuinely Interests You
Ask yourself: "Would I read an article about this on my own time?" If the answer is yes, you have found a strong candidate.
Step 2: Check for Available Sources
Even informal topics benefit from credible backing. A quick Google Scholar or JSTOR search will confirm whether research exists on your topic.
Step 3: Test the "So What?" Factor
Every good informal topic needs a hook. Ask: "Why should my audience care about this in 2026?" If you can answer that in one sentence, the topic is ready.
Step 4: Narrow It Down
Broad topics like "climate change" become manageable when narrowed: "How does climate anxiety specifically affect college students' academic performance?" is far more workable.
Step 5: Run It by Your Instructor (or a Peer)
A two-minute conversation can save hours of wasted work. Make sure the scope fits your assignment requirements before you dive in.
