In early June, a book by behavioral economics professor at Duke University Dan Ariely, “The (Real) Truth About Dishonesty: How We Lie to Everyone, Especially Ourselves,” will be published in the United States. The main thesis is this: only a few people cheat in big ways, but almost everyone cheats in small ways, and the second type of dishonesty is much more harmful, the Wall Street Journal reports, having received excerpts from the book from the author himself.
