Dan Ariely

Professor of Psychology and behavioral economics



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 holds a joint appointment between MIT's Program in Media Arts and Sciences and Sloan School of Management. He is the principal investigator of the Lab's eRationality group and a visiting professor at Duke University. Dan is also a visiting scholar at the Boston Federal Reserve Bank, 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.
Dan earned a bachelor’s degree in psychology from Tel Aviv University, his master’s and doctorate degrees in cognitive psychology from the University of North Carolina, and a doctorate in Business Administration from Duke University.

He is author of Predictably Irrational: The Hidden Forces that Shape Our Decisions, and co-author of The Joy of Experimental Psychology. His work has been published in leading psychology, economics, and marketing and management research journals. Dan serves on the editorial review board of a number of journals, including the Journal of Marketing Research, the Journal of Interactive Marketing, and the Journal of Consumer Research. He is currently working on a new book titled Dining Without Crumbs: The Art of Eating Over the Sink.
