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.
