Document Summary

A simple guide to detecting liars: he who has eyes to see and ears to hear can convince himself that no mortal can keep a secret. Only in disney world do noses grow when lies do it is not surprising, then, that people"s success at detecting lies is generally unimpressive. Although accuracy is almost always greater than chance, it is almost always never very much greater (depaulo & friedman, 1998) 2) liars do not think of controlling nonverbal behaviours. 3) liars over control nonverbal behaviours so they actually give away the truth. Now if you were trying to detect a liar where would you look first: face, speech, body. Some facial cues can betray liars but: pupil dilation, eye blinking. A microexpression is a brief, involuntary facial expression shown on the face of humans according to emotions experienced. True feelings leaking out : emotions a person is uncomfortable expressing, trying to conceal.
