This book seems like someone read some other popularizations of behavior economics, decided to do a book, and then threw together bad examples in an attempt to make an off-brand "Predictably Irrational" or something. There's absolutely no reason to read this book -- just read better popular books about the same topics (Dan Ariely's Predictably Irrational, Kahneman's Thinking, Fast and Slow, or Levitt/Dubner's Freakonomics), or the original papers (which tend to be pretty accessible).

If the other books didn't exist, and this book were original research, it would still be at best 3.5-4/5 due to just being lame. However, given that superior alternatives exist, it's 2/5. ( )
