" This book is sometimes odd because it seems to sit in the middle of three different disciplines - economics, psychology, and evolution - but that actually turns out to be a good thing, because it explains how the different disciplines tie together. A lot of the research is covered in other books, but the way he ties it together, explaining how different psychological principles probably emerged from our evolution (evolutionary psychology), but also how that effects our economic systems today - and not just models, but the real actions (irrational) people take. Shermer advances an interesting model and view of the world that's worth reading about. "
