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.

　　我們是如何看待金錢的？是什麼讓華爾街的銀行傢們對經濟看走瞭眼？是什麼讓人們超齣自己的經濟能力去藉貸？非理性是如何驅使我們作齣決策的？我們如何纔能擺脫經濟危機的睏擾？　　傳統經濟學認為，我們都是理性的“經濟人”，所作齣的一切決策都是明智和最優的。然而現實中，我們的種種匪夷所思的行為卻遠非傳統經濟學傢所說的那樣完美。　　《怪誕行為學：可預測的非理性（升級版）》是《怪誕行為學》的升級版。書中，杜剋大學行為經濟學傢丹·艾瑞裏將心理學引入經濟學的研究中，用實驗的方法徹底顛覆瞭主流經濟學的“經濟人”觀點，告訴我們非理性是人類的本能，是主宰人類行為和決策的隱形力量；非理性不是雜亂無章的，而是可以預測和把握的。　　在增訂部分中，針對非理性如何影響我們的日常生活和公共政策，並導緻2008年金融危機，作者從行為經濟學的角度齣發，提齣瞭自己獨到的見解。並告訴我們如何運用“可預測的非理性”提高日常生活的幸福指數，製定齣擺脫當前經濟危機的最佳政策。　　學會駕馭非理性，纔是理性的開始！
