Natural-Born Liars — Why do we lie, and why are we so good at it? Because it works

Deception runs like a red thread throughout all of human history. It sustains literature, from Homer’s wily Odysseus to the biggest pop novels of today. Go to a movie, and odds are that the plot will revolve around deceit in some shape or form. Perhaps we find such stories so enthralling because lying pervades human life. Lying is a skill that wells up from deep within us, and we use it with abandon. As the great American observer Mark Twain wrote more than a century ago: “Everybody lies … every day, every hour, awake, asleep, in his dreams, in his joy, in his mourning. If he keeps his tongue still his hands, his feet, his eyes, his attitude will convey deception.” Deceit is fundamental to the human condition.

Research supports Twain’s conviction. One good example was a study conducted in 2002 by psychologist Robert S. Feldman of the University of Massachusetts Amherst. Feldman secretly videotaped students who were asked to talk with a stranger. He later had the students analyze their tapes and tally the number of lies they had told. A whopping 60 percent admitted to lying at least once during 10 minutes of conversation, and the group averaged 2.9 untruths in that time period. The transgressions ranged from intentional exaggeration to flat-out fibs. Interestingly, men and women lied with equal frequency; however, Feldman found that women were more likely to lie to make the stranger feel good, whereas men lied most often to make themselves look better.
