Predictably Irrational: The Hidden Forces That Shape Our Decisions

Why do our headaches persist after we take a one-cent aspirin but disappear when we take a fifty-cent aspirin? Why do we splurge on a lavish meal but cut coupons to save twenty-five cents on a can of soup?

When it comes to making decisions in our lives, we think we’re making smart, rational choices. But are we?

In this newly revised and expanded edition of Predictably Irrational, the groundbreaking New York Times bestseller, Dan Ariely refutes the common assumption that we behave in fundamentally rational ways. From drinking coffee to losing weight, from buying a car to choosing a romantic partner, we consistently overpay, underestimate, and procrastinate. Yet these misguided behaviors are neither random nor senseless. They’re systematic and predictable—making us predictably irrational.

Predictably Irrational: Editorial Reviews

Irrational behavior is a part of human nature, but as MIT professor Ariely has discovered in 20 years of researching behavioral economics, people tend to behave irrationally in a predictable fashion. Drawing on psychology and economics, behavioral economics can show us why cautious people make poor decisions about sex when aroused, why patients get greater relief from a more expensive drug over its cheaper counterpart and why honest people may steal office supplies or communal food, but not money.

According to Ariely, our understanding of economics, now based on the assumption of a rational subject, should, in fact, be based on our systematic, unsurprising irrationality. Ariely argues that greater understanding of previously ignored or misunderstood forces (emotions, relativity and social norms) that influence our economic behavior brings a variety of opportunities for reexamining individual motivation and consumer choice, as well as economic and educational policy. Ariely’s intelligent, exuberant style and thought-provoking arguments make for a fascinating, eye-opening read. (Feb.)
