> How worthy is it /really/ for a psychologist to read up on quasars? That's a question for that particular psychologist to ask and answer for themselves. And not you nor anyone else. People have different levels of curiosity. The benefit of their curiosity isn't something that can quantified and might very well amount to nothing of any utility. That's OK. Not everything has to have an explicit ROI or "worthiness". But if you require "worthiness" consider that the psychologist might have a kid at home who has a question about quasars. What could a well-stated and intriguing answer to such a child lead to? It's impossible to say, but whatever he says it will be better than what an incurious psychologist might respond with-- "I don't know. Finish your homework and brush your teeth before going to bed".
