Predictably Irrational explains the hidden forces that really drive how we make decisions, which are far less rational than we think, but can help us stay on top of our finances, interact better with others and live happier lives, once we know about them.

Predictably Irrational is Dan Ariely's first book, and it debuted as a New York Times bestseller.

Since he's a professor of psychology and behavioral economics, how we make choices, especially about money, is his forte and prior area of interest.

How we decide what things are worth to us, what influences the way we experience the world, and how we tackle long-term goals are all shockingly irrational. This book sheds some light on just how incoherent we are, so you can be more reasonable in the future.
