Dan Ariely

Dan Ariely, born in 1967, is an Israeli-American author and professor of psychology and behavioral economics at Duke University. Born in New York City and raised in Israel, he studied psychology at Tel Aviv University, earned a master's degree in cognitive psychology and a Ph.D. from the University of North Carolina at Chapel Hill, and completed a second Ph.D. in business administration at Duke in 1998. His research on consumer behavior and decision making challenges classical economic assumptions, with work on arbitrary anchors, the zero price effect and dishonesty, and he wrote the best-selling books Predictably Irrational, The Upside of Irrationality and The Honest Truth about Dishonesty. Since 2021 the accuracy of some of his studies has been questioned, with two articles retracted and allegations of data manipulation.
