How to Choose Your Research Topic

Choosing the right research topic is likely the most important decision you’ll make on your dissertation or thesis journey. To make the right choice, you need to take a systematic approach and evaluate each of your candidate ideas across a consistent set of criteria. In this tutorial, we’ll unpack five essential criteria that will help you evaluate your prospective research ideas and choose a winner.

Criterion #1: Originality & novelty

As we’ve discussed extensively on this blog, originality in a research topic is essential. In other words, you need a clear research gap. The uniqueness of your topic determines its contribution to the field and its potential to stand out in the academic community. So, for each of your prospective topics, ask yourself the following questions:

• What research gap and research problem am I filling?
• Does my topic offer new insights?
• Am I combining existing ideas in a unique way?
• Am I taking a unique methodological approach?

To objectively evaluate the originality of each of your topic candidates, rate them on these aspects. This process will not only help in choosing a topic that stands out, but also one that can capture the interest of your audience and possibly contribute significantly to the field of study – which brings us to our next criterion.

Criterion #2: Value & significance

Next, you’ll need to assess the value and significance of each prospective topic. To do this, you’ll need to ask some hard questions.

• Why is it important to explore these research questions?
• Who stands to benefit from this study?
• How will they benefit, specifically?

By clearly understanding and outlining the significance of each potential topic, you’ll not only be justifying your final choice – you’ll essentially be laying the groundwork for a persuasive research proposal, which is equally important.

Criterion #3: Access to data & equipment

Naturally, access to relevant data and equipment is crucial for the success of your research project. So, for each of your prospective topic ideas, you’ll need to evaluate whether you have the necessary resources to collect data and conduct your study.

Here are some questions to ask for each potential topic:

• Will I be able to access the sample of interest (e.g., people, animals, etc.)?
• Do I have (or can I get) access to the required equipment, at the time that I need it?
• Are there costs associated with any of this? If so, what are they?

Keep in mind that getting access to certain types of data may also require special permissions and legalities, especially if your topic involves vulnerable groups (patients, youths, etc.). You may also need to adhere to specific data protection laws, depending on the country. So, be sure to evaluate these aspects thoroughly for each topic. Overlooking any of these can lead to significant complications down the line.

Criterion #4: Time requirements & implications

Naturally, having a realistic timeline for each potential research idea is crucial. So, consider the scope of each potential topic and estimate how long each phase of the research will take — from literature review to data collection and analysis, to writing and revisions. Underestimating the time needed for a research project is extremely common, so it’s important to include buffer time for unforeseen delays.

Remember, efficient time management is not just about the duration but also about the timing. For example, if your research involves fieldwork, there may specific times of the year when this is most doable (or not doable at all). So, be sure to consider both time and timing for each of your prospective topics.

Criterion #5: Ethical compliance

Failing to adhere to your university’s research ethics policy is a surefire way to get your proposal rejected. So, you’ll need to evaluate each topic for potential ethical issues, especially if your research involves human subjects, sensitive data, or has any potential environmental impact.

Remember that ethical compliance is not just a formality – it’s a responsibility to ensure the integrity and social responsibility of your research. Topics that pose significant ethical challenges are typically the first to be rejected, so you need to take this seriously. It’s also useful to keep in mind that some topics are more “ethically sensitive” than others, which usually means that they’ll require multiple levels of approval. Ideally, you want to avoid this additional admin, so mark down any prospective topics that fall into an ethical “gray zone”.

If you’re unsure about the details of your university’s ethics policy, ask for a copy or speak directly to your course coordinator. Don’t make any assumptions when it comes to research ethics!
