Lie detection

TECHNOLOGY

The lie detection is possible through various methodologies.

The polygraph test is possibly the best known method. But this method is only valid for very specific questions, since to begin with, it is necessary to count on sitting the person involved in front of the polygraphist to ask a maximum of 6 questions, and the answers are limited to yes or no.

To find out whether or not a person we are talking to is lying, the polygraph is obviously not the right tool. But is it really possible to detect whether the person we are talking to is lying or not? Yes. Absolutely yes.

For this, the appropriate methodology is needed, and the experts in those methodologies.

Among these methodologies we have that of Doctor Paul Ekman, which is the one currently used in the US to detect possible terrorists in airports, after 9/11.

This method for the detection of lies , based on microexpressions, requires specific training, given by Doctor Paul Ekman himself and his instructors to be carried out. Cuzco Detectives has certified detectives in this methodology, and even instructors.

The tone of voice, the words, the expressions, all these are data in the hands of an expert, to know if a person is lying or not.

For this reason, during the interviews, we not only obtain the answers that the interviewee gives us directly, but much more, thanks to the observation of their movements, their gestures, the postures, the verbs and adjectives, the ways to start the sentence, and with all this we can contribute what he is really hiding while he speaks.

How to detect a lie through body language

Is it possible to know if someone is lying to you? What clues does the liar give to grab onto to determine that he is trying to deceive you? Although it seems science fiction, it is possible to detect the lie . And it is that in the same way that it is possible to glimpse, through speech, that someone is telling us a milonga (due to their tremors in the voice or their little fluid speech), it is also possible to identify the lies of who we have in front of through of their gestures.

When the mind doubts, the hand shakes. And that is reflected in writing, ā€¯Mexican psychologist and graphologist Roberto Espinosa explains to La Vanguardia. Well, “the same goes for body language.” “When you feel threatened, the body begins to speak,” adds this psychologist, who participated last week in the VI International Forum on Graphology, Face Psychology and Body Language held in Barcelona.
