Lying is a common part of human relationships. People lie for a variety of reasons. They may lie as part of self-presentation, in order to present a more favorable image to others. People may also lie in order to minimize conflict, because lying may make disagreements less obvious. Although lying may serve useful functions in these respects, it can also be damaging to relationships. An exposed lie undermines trust and sows suspicion, because a person who has been lied to is likely to mistrust the person who lied in the future.[1] Some people even lie due to habit at first impulse. ‘Everyday lies are really part of the fabric of social life,’ says Bella DePaulo, a psychologist and lying expert at the University of Virginia. Her research shows both men and women lie in approximately a fifth of their social exchanges lasting 10 or more minutes; over the course of a week they deceive about 30 percent of those with whom they interact one-on-one. Furthermore, some types of relationships, such as those between parents and teens, are virtual magnets for deception. Lying is considered integral to many occupations: we see lawyers constructing far-fetched theories on behalf of their clients or reporters misrepresenting themselves in order to gain access to good stories.
