Professor Dan Ariely visits Google's Mountain View, CA headquarters to discuss his book "Predictably Irrational: The Hidden Forces That Shape Our Decisions." This event took place on July 1, 2008, as part of the Authors@Google series.
In a series of illuminating, often surprising experiments, MIT behavioral economist Dan Ariely refutes the common assumption that we behave in fundamentally rational ways. Blending everyday experience with groundbreaking research, Ariely explains how expectations, emotions, social norms, and other invisible, seemingly illogical forces skew our reasoning abilities. Not only do we make astonishingly simple mistakes every day, but we make the same types of mistakes, Ariely discovers. We consistently overpay, underestimate, and procrastinate. We fail to understand the profound effects of our emotions on what we want, and we overvalue what we already own. Yet these misguided behaviors are neither random nor senseless. They're systematic and predictable—making us predictably irrational.
Dan Ariely is the Alfred P. Sloan Professor of Behavioral Economics at MIT, where he holds a joint appointment between MIT's Media Laboratory and the Sloan School of Management. He is also a researcher at the Federal Reserve Bank of Boston and a visiting professor at Duke University. Ariely wrote this book while he was a fellow at the Institute for Advance Study at Princeton.
