I don't really know how to rate non-fiction books, but I gave this one 5 stars because I really loved it. Psychology is a topic that interests me a lot, especially criminal minds. I've been wanting to learn more about psychopaths in general, so I decided to pick this book up. I'm really glad I did.

Now I know how to spot a psychopath, but I also appreciated how Jon Ronson questioned what "being mad" really means, our fear of madness, and how we are surrounded by madness every day. I learned many new things I hadn't known beforehand, not only about psychopaths.
I highly recommend this to anyone who is even a little bit interested in psychology. Quick and easy to read and Ronson's investigation and humor keep you hooked.
