This book title is a little misleading and it will initially disappoint those who are looking for a book on how to read faces. However, it should be the first book that anyone interested in the subject should read.
In Reading Faces, the author spends a great deal of pages (and well researched material) to dispel the myth that there is a direct and systematic link between our facial appearance and psychological traits. But, unlike what another reviewer said, Leslie Zebrowitz does not say that there is absolutely no link between them. Through her model of appearance-traits relations in chapter 3 and 8 she explains how biology and environment can influence directly or indirectly that relation and how an individual may react to it (surfing along ones appearance => self-fulfilling prophecy; fighting it => self-defeating prophecy...).
The point is that there is no simple (simplistic, rather I should say) or systematic (if you wide a wide chin, broad jaw then it automatically means that you are strong willed, authoritarian...) appearance-traits link as some books or people pretend there is. As a matter of fact, I have yet to find a book/article/speaker on face reading that backup their system or claims with scientifically validated studies (as opposed to Leslie Zerbrowitz who thoroughly references every point she makes).
Does that mean that the other books on face reading are a waste of time or trees? No, rather they should be used with a different optic. These books could help us understand better what our face tells other and how instrumental it is in forming a first impression. According to researcher Albert Meharabian ("Non Verbal communication", Chicago, Adline-Athernon, 1972) when we first meet someone, the words we say only represent 7% of our total messages. For the rest, 38% of what is perceived is through our voice (tone, speed, intonation...) and the remaining 55% through our appearance and body language. So, do read these other books on face reading, but not before having read Leslie Zerbrowitz one (herself a baby face in a self-defeating prophecy mode from what we can read between the lines). Also, keep in mine that facial clues are significant signals that will be perceived consciously and subconsciously by other and although they do play an important role in one's life they do not represent simplistic/systematic personality traits indicators.
I don't give this book 5 star rating because of the form. The content could have been a little better organized and reader friendly. Still it remains highly readable.
