Query: Good insight

I recommend this book to anyone who is interested in understanding human behaviors and why we react the way we do under certain circumstances.I particularly fascinated by the cop's reaction after a speed trace and the research done on facial expression. A lot of decisions can be made in a blink, some are good, some are detrimental. After "Tipping point", this is another great work on human instinct and psychology.
