Lying allows a person to gain perceived control over a situation by manipulating it.
This is a defense mechanism that a liar thinks allows him to avoid opening up and revealing his true self to another person for various reasons.
If a person is lying, as a rule, he avoids making eye contact so as not to give himself away.
However, some liars, on the contrary, try to make eye contact with their interlocutor as often as possible.
A direct “eye to eye” look always gives credibility to the story, which is successfully used by many sophisticated and experienced deceivers.
If a right-handed person looks up and to the right while answering, his brain uses his imagination, which means he comes up with an answer.
When a person lies about what he heard, he looks clearly to the right.
If you ask a right-handed person what he heard, he will look in the direction of his left ear, trying to remember the auditory information.
The person will look away to be “in his head.”
There is accurate data: in order for interlocutors to experience psychological comfort from communication, the “eye to eye” look should last 2/3 of the entire conversation time, and a single meeting of the pupils should last about 20 seconds.
Next you need a break.
Simply put, understand what is normal for him: he tends to slowly draw out his words or he jabbers, he has expressive intonations or a monotonous “mumbling”.
You need to pay attention to pronunciation features, special terms, filler words and the frequency of their use.
