以下是丹教授的英文简介：

Dan Ariely (born 1968) is an Israeli professor of behavioral economics. He teaches at Duke University and is head of the eRationality research group at the MIT Media Lab.

Dan Ariely was born in New York while his father was studying for a degree at Columbia University, and he grew up in Ramat Gan and Ramat Hasharon, Israel.  His mother was a parole officer. When he was 18 and a newly enlisted soldier of the IDF he suffered third-degree burns over 70 percent of his body from an accidental magnesium flare explosion.

Ariely was a physics and mathematics major at Tel Aviv University, but transferred to philosophy when he found the writing too physically taxing.[1] He also holds an M.A. and Ph.D. in cognitive psychology from the University of North Carolina at Chapel Hill, and a Ph.D. in business from Duke University.

He was formerly the Alfred P. Sloan Professor of Behavioral Economics at MIT Sloan School of Management. Although he is a professor of marketing with no training in economics, he is considered one of the leading behavioral economists. Ariely is the author of the book, Predictably Irrational: The Hidden Forces That Shape Our Decisions (Ariely 2008), which was published on February 19, 2008 by HarperCollins. When asked whether reading Predictably Irrational and understanding one's irrational behaviors could make a person's life worse (such as by defeating the benefits of a placebo), Ariely responded that there could be a short term cost, but that there would also likely be long-term benefits, and that reading his book would not make a person worse off.
