- 01A good topic interests you, is specific, is feasible and adds something new.
- 02Recent reviews and the “future research” sections of papers are the best source of ideas.
- 03Narrow it down until you can sum up your question in one sentence.
01What makes a topic good?
- It genuinely interests you. You will spend months with it; interest is what keeps you going when the work gets hard.
- It is specific. Not “education” or “social media”, but a particular aspect, place, period or group.
- It is feasible. You have access to the sources or data, the time is enough and you know the languages you need.
- It adds something. A new case, a different approach, an understudied population or a question that is still open.
02How to find your topic in 6 steps
Start from what already intrigues you
Write down the questions you have asked yourself in class, at work or while reading. The best topics usually come from your own curiosity, not from a list of available topics.
Read recent reviews in your field
Review articles and literature reviews from the last few years summarize what is known and what is missing. They are the fastest way to see the whole map.
Look for “future research” sections
Many authors end their papers by pointing out what remains to be studied. Those final pages are an excellent source of topics.
Narrow the topic
Define the place, period, population or approach. From “social media and teenagers” you can move to “TikTok as a source of information among secondary school students in a specific city”.
Check that it has not already been answered
Search Google Scholar and the databases in your field with exact terms, in more than one language if you can. If you find a lot, do not drop it right away: look for the part that is still unanswered.
Turn it into a question and get feedback
Write a clear research question and discuss it with your supervisor or a professor in the field. A few minutes of conversation can save you months.
Originality is rarely in the topic. It’s in the question you ask about it.
03Example: from a broad interest to a research question
| Stage | Wording |
|---|---|
| Broad interest | Artificial intelligence in education. |
| Narrower topic | The use of AI writing assistants at university. |
| More precise topic | How first-year psychology students use AI assistants when writing their assignments. |
| Research question | What uses of AI assistants do first-year psychology students report when writing their assignments, and how do their professors view them? |
Once you have your question, the next step is to organize the work. We explain how in how to structure a thesis.
04Common mistakes
- A topic that is too broad. If you cannot sum up your question in one sentence, it is not narrow enough yet.
- Choosing it only because it is trendy. A popular topic may be saturated; what matters is what you can add.
- Not checking the sources before starting. A brilliant topic without accessible data or literature becomes a problem.
- Mistaking an apparent gap for a real one. Sometimes a topic only looks unstudied because it was researched under other terms or in another discipline.
Frequently asked questions
What teachers ask most often.
How do I know if my topic is too broad?
If you cannot sum up your question in one sentence, or answering it would take years and resources you do not have, it is still too broad. Narrow it by place, period, population or approach.
Does the topic have to be completely new?
No. It is enough to add something: study a case in another context, apply a different approach or use more recent data. Originality usually lies in the angle, not the topic.
What if I find out it has already been studied?
Do not drop it right away. Check what those studies say in their limitations and future research sections: there is almost always a population, a period or a method left uncovered.
When should I talk to my supervisor?
Early, once you have two or three options with a tentative question for each. It is easier to adjust a topic at the start than to change it after months of work.
