3.0

The author is a narcissistic jerk, but that is the point. He is aware of (and proud of, I would say) this, of being a "prosocial psychopath" as he labels himself. This book was interesting, but really dragged at points, especially when he patted himself on the back over and over. But it was fascinating to learn more about what "makes" a psychopath and even see the author's own understanding and insight evolve. I'm glad I read it, and even more glad that I never have to deal with this man.
