<p><b>From the Back Cover</b><br><p>Why do our headaches persist after we take a one-cent aspirin but disappear when we take a fifty-cent aspirin? </p><p>Why do we splurge on a lavish meal but cut coupons to save twenty-five cents on a can of soup? </p><p>When it comes to making decisions in our lives, we think we're making smart, rational choices. But are we? </p><p>In this newly revised and expanded edition of the groundbreaking <em>New York Times</em> 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.</p></p>
