Description

"A marvelous book... thought provoking and highly entertaining." --Jerome Groopman, New York Times bestselling author of How Doctors Think

"Ariely not only gives us a great read; he also makes us much wiser." --George Akerlof, 2001 Nobel Laureate in Economics

"Revolutionary." --New York Times Book Review

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 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.

Back cover copy

How do we think about money?
What caused bankers to lose sight of the economy?
What caused individuals to take on mortgages that were not within their means?
What irrational forces guided our decisions?
And how can we recover from an economic crisis?

In this revised and expanded edition of the New York Times and Wall Street Journal bestseller Predictably Irrational, Duke University's behavioral economist Dan Ariely explores the hidden forces that shape our decisions, including some of the causes responsible for the current economic crisis. Bringing a much-needed dose of sophisticated psychological study to the realm of public policy, Ariely offers his own insights into the irrationalities of everyday life, the decisions that led us to the financial meltdown of 2008, and the general ways we get ourselves into trouble.

Blending common experiences and clever experiments with groundbreaking analysis, Ariely demonstrates how expectations, emotions, social norms, and other invisible, seemingly illogical forces skew our reasoning abilities. As he explains, our reliance on standard economic theory to design personal, national, and global policies may, in fact, be dangerous. The mistakes that we make as individuals and institutions are not random, and they can aggregate in the market--with devastating results. In light of our current economic crisis, the consequences of these systematic and predictable mistakes have never been clearer.

Packed with new studies and thought-provoking responses to readers' questions and comments, this revised and expanded edition of Predictably Irrational will change the way we interact with the world--from the small decisions we make in our own lives to the individual and collective choices that shape our economy.

Review Text

"This is a wonderful, eye-opening book. Deep, readable, and providing refreshing evidence that there are domains and situations in which material incentives work in unexpected ways. We humans are humans, with qualities that can be destroyed by the introduction of economic gains. A must read!" Nassim Nicholas Taleb, New York Times bestselling author of The Black Swan: The Impact of the Highly Improbable
