A truly excellent read that's a bizarre hybrid between a social economics journal and a self help book. Ariely manages to take a very dry topic (economics) and turn it into a fascinating discussion on the irrationalities of human nature. Each chapter continues an extensive list of references and Ariely has performed experiments to give his observations a verifiable backing. As well as making for entertaining reading (I have sympathy for anybody taking his classes, they end up as guinea pigs a lot) this helps the book distance itself from the empty hypotheses that some of its peer indulge in.
