Document Summary
How accurate is the average person at detecting deception: only slightly better than chance; but training and practice can improve one"s skills, i. e. , federal officers have over 70% and law enforcement have just over 50% 1981: mismatch between the behaviours that actually signal deception and those used by perceivers to infer deception i. e. , people touching their noses means they"re lying or untrustworthy -> inferred deception, cues. Body -> hard to control (fidget, restless) Voice -> hard to control (best cue; pitch raises/hesitation when lying) > the best poker face for bluffing is not a neutral face, but a face that contains emotional correlates of trustworthiness (looking happy) Ted talk: jeff hancock: 3 types of digital lies.
