The one from Costco ? <| sep |> You don ' t have to study something to be smarter than another person in that subject . Especially if they didn ' t study it either . I have actually studied some poly sci though , it ' s just not my major . I know enough about different state actors , political norms , tendencies of insurgencies vs terrorism , etc to have anot informed opinion . If I ' m in a chat against someone who studies political science and they ' re an expert in the field , I wouldn ' t suggest I knew more than them . I mostly studied international relations vs comparative or American politics I think ethics was another concentration ? , but I can have a decently informed conversation . Mostly I know how to research , which if you can research you should be able to argue on any subject when given time to prepare . Again , doesn ' t mean you ' ll be able to stack up to an expert , but if it ' s someone who knows less than you then you should be fine . It ' s almost as if people can learn about more than one thing .
