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.

　　我们是如何看待金钱的？是什么让华尔街的银行家们对经济看走了眼？是什么让人们超出自己的经济能力去借贷？非理性是如何驱使我们作出决策的？我们如何才能摆脱经济危机的困扰？　　传统经济学认为，我们都是理性的“经济人”，所作出的一切决策都是明智和最优的。然而现实中，我们的种种匪夷所思的行为却远非传统经济学家所说的那样完美。　　《怪诞行为学：可预测的非理性（升级版）》是《怪诞行为学》的升级版。书中，杜克大学行为经济学家丹·艾瑞里将心理学引入经济学的研究中，用实验的方法彻底颠覆了主流经济学的“经济人”观点，告诉我们非理性是人类的本能，是主宰人类行为和决策的隐形力量；非理性不是杂乱无章的，而是可以预测和把握的。　　在增订部分中，针对非理性如何影响我们的日常生活和公共政策，并导致2008年金融危机，作者从行为经济学的角度出发，提出了自己独到的见解。并告诉我们如何运用“可预测的非理性”提高日常生活的幸福指数，制定出摆脱当前经济危机的最佳政策。　　学会驾驭非理性，才是理性的开始！
