(Dis)Honesty: The Truth About Lies

Dan Ariely, a professor of psychology and behavioral economics at Duke University, hosts this documentary about why people lie. Synopses of experiments Ariely has conducted alternate with short profiles of people who’ve been exposed for lying; the talking heads include a former pro cyclist who admits he took steroids, a Florida housewife whose husband caught her having an affair, and three figures in the WorldCom accounting scandal of 2002. The reason so many people lie, Ariely concludes, is that they have so many ways of justifying it, though he ends on a positive note by recounting some successful experiments in promoting honesty among strangers.
