Frequently Asked Questions

How do I know if my dissertation topic is original?
Conduct a thorough literature search using academic databases such as Scopus, Web of Science, JSTOR, or your discipline’s specialist databases. If multiple recent, high-quality studies have already answered your exact question in the same context, you need to refine your angle. True originality can mean applying an existing framework to a new context, using a novel methodology, or investigating a question that has been overlooked in the existing literature.

Can I change my dissertation topic after I start?
Yes, but the earlier the better. Changing topic during the initial reading and planning stage is low-cost. Changing topic after ethics approval has been received, data has been collected, or substantial writing has been done carries a significant cost in wasted work. Discuss any change of direction with your supervisor as early as possible.

Should my dissertation topic reflect current events?
Engaging with contemporary issues can make your dissertation more topical and potentially more impactful. However, very recent events may lack a sufficient body of peer-reviewed literature for a thorough literature review. Balance currency with the availability of academic evidence.
