I love books that deal with this type of behavioral economics or odd psychological principles, but can't seem to get very many others interested in them. If someone asked me for a recommendation on the subject now, this would be one of the top two I would suggest to them. It's fast paced, packed with information, and can easily lead to more reading. There was definitely some new information here, but not as much as I expected.
Some of things I learned include what drawing a Q on your forehead means about your lying ability, whether people would wear a sweater once owned by a mass murderer, and how to double your panhandling intake with one phrase. There is a ton of information here, and its really great stuff. Well worth your time.
