Is it easy to spot a liar?
According to psychologists, the average human being lies to others once or twice a day.This is because deception- or `untruthfulness`- is a natural tendency amongst all living things.Many animals deceive others aeound them in orderto distract predators from baby birds in their nest.Chimpanzees, when they are foraging for food and come across something tasty, will occasionally pretend not to have noticed the food so as not to alert the chimps nearbyand lose their prize .So it is no surprise that human beings often deceive for exactly the same reasons:to save theirown skins or to get something they can`t get by other methods.
Desprite how often they engage in it, most people aren`t experts at lying.People often make inconsistent facial expressions and body movements in a desperate attemt to seem believable and to supress what they are realy thinking.
