Why is the correct topic selection very important in IR?

A number of students considered topic selection as a after-thought, and making a decision of 5 minutes before a real writing initiative is a very big mistake for students.

Your international relations research topic deals with:

• How much literature in academia can you find? It includes your niche and struggles with the sources.
• How original is your argument? It should not be very broad and repeat what has already been discussed by anyone.
• How does your work convey relevant feelings? Your topic should not be outdated because it can make your engagement lower and minimise thinking marks. 
• How confident does your work sound? Discussing the things in writing that contain genuine interest can make your work the best.

The incredible part of the story is that international relations in the year 2026 are coming with the relevant, genuine and fascinating research angles. The conflict between Russia and Ukraine has also reached the security of Europe. 

The rivalry between the US and China is also redefining global trade. Artificial intelligence is entering the diplomatic world. Negotiations in China are shifting the balance of power throughout the Global South Region. Nowadays, the best time is for studying IR.

How to Select the Best IR Topic for your Assignment?

Before going to dive in the list of topics here, you need to spend 2 minutes answering all these questions. It will assist you in filtering out more than 100 to find the one that is appropriate for you.

Ask these four questions of yourself before selecting a topic

What type of assignment is it?

A dissertation, an essay, a research proposal, and a policy brief all contain multiple categories of the topic. At the time of writing your essay, you have to select the debatable arguments. The dissertation requires a research gap with narrowness. Whereas the requirements of policy briefs are real-world relevance and practicality.

What is your academic level?

The topics at the undergraduate levels are more descriptive and broader. Whereas, the postgraduate topics should push the theoretical framework, original analysis and empirical research caps.

What contains your genuine interest?

A topic of research in which you find yourself bored can produce work which is very boring. You should spend the time on the topic that makes you happy and interested.

 Is there appropriate academic literature available?

 Before going towards a topic, you should check out whether the academic literature is available on your databases and Google Scholar. If you find only a few sources, then your topic may be very narrow.
