The premise of this book is that non-verbal communication accounts for 60 to 65% of all interpersonal communication. Non-verbal communication largely originates in the unconscious mind and is therefore immediate and hard to manipulate. Verbal communication can be manipulated and is not a good source of reliable information. Very few classes exist on how to read non-verbal communication, and therefore it falls upon us to learn these skills.
I found this book to be very helpful in watching for small cues that people unknowingly portray through their body language. The author makes clear that these cannot be relied upon completely, but can lead you to question someone when you know they are uncomfortable. This could be in an interrogation or in a business meeting. In fact, this would be a great book for CEOs to learn how to better be able to read body language during meetings.
This book is a relatively quick read with lots of visual examples and is one of those books that reveals things in plain site you’ve been missing your entire life.
