Query: Phrenology for the '90s

If you wish learn to identify people's personalities or how they may be feeling or may be thinking at a given moment then his book is a waste of your time and money. The ideas in this book are nothing but pseudoscientific nonsense. The text is full of glittering generalities and vague statements which nearly anyone would agree were true about them, regardless of face shape. If you wish to truly read people, your time and money would be much better spent on just about anything by Paul Ekman or any of the books by Desmond Morris on human social interaction. Avoid this book.
