Product description


"A taxonomy of financial folly."--The New Yorker

"Ariely's book addresses some weighty issues . . . with an unexpected dash of humor."--Entertainment Weekly

"Ariely's intelligent, exuberant style and thought-provoking arguments make for a fascinating, eye-opening read."--Publishers Weekly

"In creative ways, author Dan Ariely puts rationality to the test. . . . New experiments and optimistic ideas tumble out of him, like water from a fountain."--Boston Globe

"Inventive. . . . An accessible account. . . . Ariely is a more than capable storyteller . . . If only more researchers could write like this, the world would be a better place."--Financial Times

"Surprisingly entertaining. . . . Easy to read. . . . Ariely's book makes economics and the strange happenings of the human mind fun."--USA Today

"Sly and lucid. . . . Predictably Irrational is a far more revolutionary book than its unthreatening manner lets on."--New York Times Book Review

"A delightfully brilliant guide to our irrationality--and how to overcome it--in the marketplace and everyplace."--Geoffrey Moore, author of Crossing the Chasm and Dealing with Darwin

"A fascinating romp through the science of decision-making that unmasks the ways that emotions, social norms, expectations, and context lead us astray."--Time magazine

"A marvelous book that is both thought provoking and highly entertaining, ranging from the power of placebos to the pleasures of Pepsi. Ariely unmasks the subtle but powerful tricks that our minds play on us, and shows us how we can prevent being fooled."--Jerome Groopman, New York Times bestselling author of How Doctors Think

From the Back Cover

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.
