In college, I liked to go to the journals area and look through different topics. I would read about anthropology, gender studies, economics, psychology. It’s hard to do that now since I don’t have access to a university library and so many studies are gated online by the big publishers.
If you’re a nerd like me that likes finding cool academic papers about random, interesting topics, then you’ll like SSRN.
Another tip is if you find a study online that you really want to read and can’t find the full paper for free, email one of the authors. They will often send you the paper (for free!).
