How do we think about money?What caused bankers to lose sight of the economy?What caused individuals to take on mortgages that were not within their means?What irrational forces guided our decisions?And how can we recover from an economic crisis? In this revised and expanded edition of the New York Times and Wall Street Journal bestseller Predictably Irrational, Duke University's behavioral economist Dan Ariely explores the hidden forces that shape our decisions, including some of the causes responsible for the current economic crisis. Bringing a much-needed dose of sophisticated psychological study to the realm of public policy, Ariely offers his own insights into the irrationalities of everyday life, the decisions that led us to the financial meltdown of 2008, and the general ways we get ourselves into trouble.Blending common experiences and clever experiments with groundbreaking analysis, Ariely demonstrates how expectations, emotions, social norms, and other invisible, seemingly illogical forces skew our reasoning abilities. As he explains, our reliance on standard economic theory to design personal, national, and global policies may, in fact, be dangerous. The mistakes that we make as individuals and institutions are not random, and they can aggregate in the market—with devastating results. In light of our current economic crisis, the consequences of these systematic and predictable mistakes have never been clearer.Packed with new studies and thought-provoking responses to readers' questions and comments, this revised and expanded edition of Predictably Irrational will change the way we interact with the world—from the small decisions we make in our own lives to the individual and collective choices that shape our economy.

1) "If companies want to benefit from the advantages of social norms, they need to do a better job of cultivating those norms. Medical benefits, and in particular comprehensive medical coverage, are among the best ways a company can express its side of the social exchange. But what are many companies doing? They are demanding high deductibles in their insurance plans, and at the same time are reducing the scope of benefits. Simply put, they are undermining the social contract between the company and the employees and replacing it with market norms. As companies tilt the board, and employees slide from social norms to the realm of market norms, can we blame them for jumping ship when a better offer appears?"

2) "Money, as it turns out, is very often the most expensive way to motivate people. Social norms are not only cheaper, but often more effective as well."

3) "As I mentioned, the cans of Coke quickly disappeared; within 72 hours every one of them was gone. But what a different story with the money! The plates of dollar bills remained untouched for 72 hours, until I removed them from the refrigerators.
So what's going on here?
When we look at the world around us, much of the dishonesty we see involves cheating that is one step removed from cash. companies cheat with their accounting practices; executives cheat by using backdated stock options; lobbyists cheat by underwriting parties for politicians; drug companies cheat by sending doctors and their wives off on posh vacations. To be sure, these people don't cheat with cold cash (except occasionally). And that's my point: cheating is a lot easier when it's a step removed from money."

Traditional economic models are based on the assumption that consumers behave rationally, ie, act in their own self-interest. The author is a behavioral economist, and the book looks at many different situations and examples of ways in which consumers do not, in fact, act rationally. There are many unconscious factors and biases that influence our decisions, and the author steps through examples of them chapter by chapter, explaining what they are, how they cause us to act irrationally, and how to avoid falling into that trap. Very interesting reading with lots of applications both to personal life and business. Certainly recommended to anyone with any interest in why humans behave the way we do.
