This was one of the books that changed the way I see people around me.
In a strictly scientific analysis, Zebrowitz explores the tendency to judge people by the way they look. Why? Can we trust it?
Almost all book is devoted to this first question - why we do it? And explains why we find some faces more atractive than others, the sex-appealing face cues, the main parts of the face that we look at and if they have some link to the way people are (their behaviour and personality).
The final chapter concludes that there is no scientific evidence that we can link the facial cues to one's personality. However the interesting thing of the book is the scientific facts and studies that you get to know before you come to the conclusion.

A massive study on all aspects of face attraction and perception.
