Sometimes it feels like the whole world is cheating. And, according to behavioral economics professor Dan Ariely, that's because it is. In his latest book The (Honest) Truth About Dishonesty, Ariely makes the case that ticket-fixing, Ponzi schemes, and extramarital affairs are a natural part of the human condition. That might be easy to believe, but here is where it gets deep: Ariely says that we lie to ourselves too. For example, when we inflate our résumés on paper, we inadvertently inflate them in our heads. He also claims that cheating and dishonesty are not caused by an internal "cost/benefit" analysis of such behavior, but stem from irrational forces we often fail to take into account. To prove his point, Ariely uses real-life anecdotes from his time in charm school, visits the fashion industry, and draws on research he conducted for various scientific journals, as well as his previous books, The Upside of Irrationality and Predictably Irrational.
