Thre are some people who can’t tell a lie, many who can’ttell the truth, and unfortunately, most people can’t tell the difference.Can yu tell when someone is pulling the wool over your eyes? When we were children, we were raised to tell the truth and taught that honesty is always the best policy. We were told stories about George Washington and Honest Abe Lincoln to reinforce the virtue of truthfulness. However,as we grew older,we realized that the truth sometimes hurts and that few relationship could survie the harsh reality of brutal honesty. To keep from hurting others, we learned the usefulness of telling “white lie” On the other hand, self –serving lies can be damaging and are frequently used for personal gain or to avoid punishment.
Scientists looking for a reliable way to expose liars invented the polygraph machine, also known as the lie detector, in the 1920’s.While certainly not a perfect machine,it is estimated that the lie detector has aninety percent accuracy rate. While polygraph evidence is not permitted in a courtroom,the CIA,FBI,police,and employers routinely use it as an interviewing tool. In addition to using a lie detector,many law enforcement agencies videotape interviews in order to evaluate body language gesture indetail. Gestures or expressions that occur in less than one second are called micro gestures. Micro gesturea are extremely difficult to abserve unless they have been recored on videotape and played back in slow motion. Body language axperts have identified and categorized thousands of hman gestures and their associated meaning. It might surprise you to know that research indicates over 65% of our communication is done nonverbally. In fact,studies show that nonverbal communication is done nonverbally. In fact,studied show that nonverbal ommunication has much greater impact and reliability than the spoken word.
Body language is a complex mixture of movement,posture, and tone of voice. Developing a working understanding of body language is similar to learning a foreign language in that it requires time and effort to achieve mastery. Typically,when someone is lying,they subdue their gesture and avoid direct eye contact,or have what is termed,”shifty eyes”. The three primary facial gesture associated with lying are called;”speak no evil,see no evil,and hear no evil.”the “speak no evil”gesture is when someone filters their words through their fingers or use theit hand to block their word. The gesture”see no evil”occurs when an idividal rubs their eyes while they are talking. The third facial gesture,”hear no eil”,occurs when a person covers their ears or drills their finges into their ear a they are speaking.The two,less obvious lying gestures are micro gestures,which require close abservation to detect. The first of these subtl,but important micro gestures is a nose wrinkle. This is the same gesture that accurs naturally when you smell something offensive. The other facial micro gesture that is used to detect lying is slight downward curl of the corners f the mounth. People sometimes lie,although their body language always tells the truth
