Summary: Although Dan Ariely is an academic by trade, he is a pragmatist at heart. The Duke professor and best-selling author brings his theories to light through practical applications and behavioral experiments, where irrationality is almost always certain. Ariely has written two books on the subject--The Upside of Irrationality and Predictably Irrational. In February 2011, he sat down with Olivier Sibony, a director in McKinsey's Paris office, to share his insights into human behavior that can help companies make better decisions.
