Have you read The Psychopath Test?

I was surprised to read what he had to say about the DSM. To think it was a handful of people yelling over each other, arbitrarily making up diagnoses, just makes me sick. It sounds as though the DSM wasn't constructed with valid scientific tests, case studies, or peer review.

I'm going to do more research next week when I get a chance. From my perspective right now it doesn't seem like the DSM has much credibility.
