As a behavioral economist, Dan Ariely studies how people actually act in the marketplace, as opposed to how they should or would perform if they were completely rational. His interests span a wide range of daily behaviors such as buying (or not), saving (or not), ordering food in restaurants, pain management, procrastination, dishonesty, and decision making under different emotional states. His experiments are consistently interesting, amusing, and informative, demonstrating profound ideas that fly in the face of common wisdom.

Dan is the James B. Duke Professor of Behavioral Economics at Duke University and a visiting professor at MIT's Media Lab. He is also a founding member of the Center for Advanced Hindsight, a fellow at Diamond Management and Technology Consultants, and President elect of the Society for Judgment and Decision Making.
