There are five questions in total, choose question one. I am undergraduate student which is 3000 worlds.
1: the research question should not be obvious and should generate some puzzle. For example (why do people accept X environmental policy if it is not in their best economic environmental protection in country Z?)
2: You should start exploring primary and secondary sources related to your topic/research question in the library and on web engines (e.g google Scholar)
3:whatever your topic /research question of choice, remember to focus your argument on a causal relationship .
while you may identify different variables, focus an independent variable .
(e.g an interest , a norm, a political mechanism) and an outcome variable. (e.g. an opinion , a policy) and how they are related.
4. You need to find examples and empirical applications for your argument. This applies also if you choose to write a theoretical essay.
