He showed 99 police officers tapes of real-life lies and truths and found that the officers were, at 65 percent accuracy, slightly better than lab-study participants at discerning the difference. "Human accuracy is really just barely better than chance," says DePaulo. Pinocchio's nose just doesn't exist, and that makes liars difficult to spot.
"Their stories are too good to be true," says Bella DePaulo of the University of California, Santa Barbara, who has written several reviews of the field of deception research.

Before learning the police conclusions, Vrij's team analyzed the videotapes for signs of the suspects' nonverbal reactions to questioning, such as gaze aversion, blinking, and hand-and-arm movements. There's no significant reward for a liar who's believed or punishment for a judge who's duped.

Such emotions can trigger a change in facial expression so brief that most observers never notice. However, Levine speculates that even a bogus program can succeed by simply getting people to pay attention. free real money online poker The Secret Service group had a better-than-chance distribution, with nearly one-third of the agents getting 8 out of 10 determinations correct, the San Francisco psychologists reported affordable travel to europe in 1991.
