Despite our intentions, why do we so often fail to act in our own best interest? Why do we promise to skip the chocolate cake, only to find ourselves drooling our way into temptation when the dessert tray rolls around? Why do we overvalue things that we’ve worked to put together? What are the forces that influence our behavior? Dan Ariely, James B. Duke Professor of Psychology & Behavioral Economics at Duke University, is dedicated to answering these questions and others in order to help people live more sensible – if not rational – lives. His interests span a wide range of behaviors, and his sometimes unusual experiments are consistently interesting, amusing and informative, demonstrating profound ideas that fly in the face of common wisdom.
He holds appointments at Duke’s Fuqua School of Business, the Center for Cognitive Neuroscience, the Department of Economics, the School of Medicine, and is a senior fellow at the Kenan Institute for Ethics at Duke.
He is a founding member of the Center for Advanced Hindsight and the author of the New York Times bestsellers Predictably Irrational, The Upside of Irrationality, and The Honest Truth About Dishonesty. In 2013 Bloomberg recognized Dan as one of Top 50 Most Influential thinkers. He also has a bi-weekly advice column in the Wall Street Journal called “Ask Ariely.” Dan can be found at www.danariely.com.
