Predictably Irrational - The Hidden Forces That Shape Our Decisi

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.
