What Predictably Irrational is about

Dan Ariely, a behavioral economist at Duke University, challenges the comfortable idea that we make decisions by thinking rationally. Through a wide range of experiments, findings, and often amusing anecdotes, he shows that expectations, emotions, social norms, and other invisible forces bend our reasoning. His central point is that our mistakes are not random. They are systematic and repeat again and again, and seeing the pattern can help us avoid some of them.

The revised and expanded edition applies this thinking to the 2008 financial meltdown, asking why bankers lost sight of the economy and why individuals took on mortgages they could not afford. Ariely also warns that basing policy on standard economic theory may be dangerous. Witty and accessible, the book will suit anyone curious about why they and the people around them behave as they do, from shoppers and managers to anyone who has wondered about a bad decision.
