Predictably Irrational, Revised and Expanded Edition The Hidden Forces That Shape Our Decisions

<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 <i>New York Times</i> 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>
