Well I'd agree to buy a book that is thorough in its science, but how do you really know its science is good enough? Same problem. Should I extensively read scientific literature on the subject, or should I just read books that are close to being mumbo jumbo, since it's aimed to be read by non scientists?

A psychiatrist is someone who had extensive education in psychology and medicine, who I can talk to. That's a little easier to sense things when you're face to face with somebody. It's much easier that way, just like it's easier to learn a complicated subject by asking questions instead of reading many books.

I guess you're right, I could read a book on the subject, but I'm a little skeptic...
