It’s time to abandon that assumption. | by Dan Ariely IN 2008, a massive earthquake reduced the ﬁnancial world to rubble. Standing in the smoke and ash, Alan Greenspan, the former chairman of the U.S. Federal Reserve once hailed as “the greatest banker who ever lived,” confessed to Congress that he was “shocked” that the markets did not operate according to his lifelong expectations. He had “made a mistake in presuming that the self-interest of organizations, speciﬁcally banks and others, was such that they were best capable of protecting their own shareholders.” Jacob Thomas

THE NEW ECONOMICS
We are now paying a terrible price for our unblinking faith in the power of the invisible hand. We’re painfully blinking awake to the falsity of standard economic theory – that human beings are capable of always making rational decisions and that markets and institutions, in the aggregate, are healthily self-regulating. If assumptions about the way things are supposed to work have failed us in the hyperrational world of IN BRIEF Wall Street, what damage have they done in other institutions » The global economic crisis has and organizations that are also shattered two articles of faith in standard economic theory: made up of fallible, less-thanthat human beings usually make logical people?

The emerging ﬁeld of behavioral economics offers a radically different view of how people and organizations operate. In this article I will examine a small set of long-held business assumptions through a behavioral economics lens. In doing so I hope to show not only that companies can do a better job of making their products and services more effective, their customers happier, and their employees more productive but that they can also avoid catastrophic mistakes.
