How to spot a liar?

Liars want you to believe they tell the truth. Synergology focuses on signs of vigilance and control instead of looking for the identification of emotions. Why? Common sense suggests that a lying person is not at ease. But a liar knows that if he looks uncomfortable he will be taken for a liar. Better is to look confident! The same for the eyes: a liar will look more in the eyes of his interlocutor to prove he tells the truth! (Kassin and Fong, 1999)

A liar will prevent, or slow down his actions: no area of ​​the brain is directly involved in the production of emotions. In order to mislead his questioner a liar uses brain areas involved in the control of words, gestures and the control of attention. Observed on MRI are the anterior cingulate cortex, the superior frontal gyrus, left premotor cortex and parietal areas of the cortex that are active in the production of lies. (Langleben et al, 2002)

The liar must always compare his lies with the truth to construct a plausible discourse. And as he must handle many thoughts at the same time his body stiffens, spite of himself. It is also impossible to relax completely because the areas responsible for monitoring and control of speech gestures are directly related and connected to each other. Control over the body can be spotted on ex: the key areas of hands and eyes. They become very visible when the person stops to lie and relaxes (Leal and Vrij, 2008).

Decoding a lie observing movements of the body is promising! The body did not learn to lie: we observe authenticity or controlled behavior and recognize a lie or verify when a person is telling the truth… If the existence of a lie can not be argued by the evidence of body language in court of justice, good observation and accurate questioning is the guide to further paths. Non verbal clusters indeed helps the questioner to bring the respondent on the road of concrete elements at moments of well observed blockage or control.
