Even when Ekman requires extensive training of testers, he has apparently not published a single study that confirms his figures. According to Maria Hartwig of the John Jay College of Criminal Justice, such claims are “simply implausible.” The research literature, by contrast, suggests that success rates are generally barely above chance. In his book Telling Lies, Ekman claims that, in laboratory experiments, truth and lies can be told apart by facial expression alone with an accuracy of more than 80 percent-and that the figure reached 90 percent when factors such as facial and body movements, voice and language were all included in one analysis.īut these statistics may be misleading. That is why repeated and varied clues are necessary one is not enough. He merely thinks they are indications that something might be off. Ekman does not believe that such discrepancies are proof of falsehood. And the eye muscles may not be involved in a false smile. For example, if we try to fake fear or sadness, the characteristic creases on our forehead may not show.
We are more apt to observe emotions that are broken off or incomplete. Such microexpressions that reveal concealed emotions do not, however, occur all that often, according to Ekman. A prime example is a momentary facial expression that lasts no longer than a quarter to a half a second and is virtually invisible to an unpracticed observer. The core idea: emotions that one seeks to conceal are sometimes betrayed by facial expressions and movements of the arms, hands, legs and feet. Friesen laid the groundwork for Ekman’s popular theory of lies in their 1969 paper “Nonverbal Leakage and Clues to Deception,” which dealt with patients’ nonverbal signals. Ekman categorized the facial muscles involved in producing these expressions in what he called the Facial Action Coding System. In the 1960s he formulated his theory of universal facial expressions for the basic emotions: anger, disgust, enjoyment, fear, sadness and surprise. Starting before that time, he became the first researcher to examine, on a large scale, how observable changes in the face and body reflect truth telling or lying. But in everyday life we use the same instruments as our ancestors in distinguishing truth from falsehood: our eyes and ears.įrom 1971 to 2004 Ekman was a psychology professor at the University of California, San Francisco, where he is now emeritus.
Among other things, so-called polygraphs register how sweat production, heart rate and breathing change when certain questions are asked. have been trying to separate truth from fiction by using lie detectors. If his lips are silent, he chatters with his finger-tips betrayal oozes out of him at every pore.” Since the middle of that century, security experts in the U.S. In commenting on a case at the beginning of the 20th century, Sigmund Freud wrote, “He that has eyes to see and ears to hear may convince himself that no mortal can keep a secret. describes the behavior of an attempted poisoner as follows: “He does not answer questions, or they are evasive answers he speaks nonsense, rubs the great toe along the ground, and shivers his face is discolored he rubs the roots of the hair with his fingers.” An ancient Indian text from about 900 B.C. Ekman’s credo is that the truth is written on our face.
He not only advised the creators of the program but has also been called upon by numerous U.S.
#LIE TO ME PROGRAM SERIES#
The expert on microexpressions in the TV series Lie to Me is the alter ego of Paul Ekman, age 86, a world-renowned researcher of lying and emotion. The evidence is open-and-shut as far as the expert is concerned: The suspect’s body language contradicts his words. And he shrugs his shoulders as he pronounces his innocence. But when his interrogator mentions the correct place, the terrorist’s face betrays a flash of rage. He is happy because he thinks the investigators are wrong about where he planted the bomb. For a fraction of a second, the suspect raises the corner of his mouth.
