That's the dumbest haircut I've ever seen. No way, Jose. Bella DePaulo of the University of Virginia at Charlottesville, who has done several studies on lying in everyday life, notes that no one is totally honest all the time. One of DePaulo's studies, published in the Journal of Personality and Social Psychology, showed that people told at least one lie a day, and that more socially adept folks stretched the truth more often than the less sophisticated. There's a reason the devil is always depicted as a smooth-tongued fellow.
Facility breeds falsity.
In the end, Presidents lie for the same reason everyone else does. In his briefest of speeches on Monday night, Clinton offered a taxonomy of lying. First, by a desire to protect myself from embarrassment. This is the one breathtaking line in his speech, because it is breathtakingly self-aware. Sociologists suggest that almost all lies, certainly the most pernicious ones, are motivated by self-interest.
