Gestures are much more difficult to control than intonation. That is why even a person who confidently utters a prepared lie in advance can easily be betrayed by involuntary movements.
Instructions
Step 1
See if the other person brings his hand to his mouth. This is a childish gesture that adults cannot get rid of either. When telling a lie, the child often automatically brings his hand to his mouth, as if trying to close it. Adults can change this gesture somewhat: involuntarily bringing their hand to their lips, they catch themselves and begin to stroke their chin, touch their nose, cheeks, hair, etc. Please note: this is a light touch, not scratching.
Step 2
Observe how the person's expression changes. If his lies are very serious and he is afraid of exposure, his forehead may even be covered with sweat. Often, a facial expression that clearly betrays excitement or fear is combined with an unusual gesture - pulling back the collar or scratching the neck. But keep in mind that a person may also pull back their collar when they are very upset, angry, or simply not feeling well and begins to notice that they are short of air.
Step 3
Pay attention to the gaze of the interlocutor. If a person just looks away, this does not mean that he is lying, especially if you asked a question that can only be answered by remembering a fact. However, the person who is lying doesn't just look away. He may start rubbing the lower or upper eyelid, touching the eyelashes, as if trying to close his eyes. Women who have done makeup involuntarily change this gesture so as not to erase shadows, eyeliner or mascara: they begin to stroke the upper part of the cheek, lightly touch the skin under the eyebrows, etc.
Step 4
Try to determine how appropriate and timely the person's gestures are. If his movements are somewhat slow, he is most likely lying. At such moments, a person deliberately tries to repeat the usual, easily readable movements, but does it at the wrong time, since he does not act spontaneously. For example, getting angry, people sometimes slap on the table, moreover, first they perform a gesture, and then they begin to speak, or they do both almost simultaneously. A liar trying to play the part of a person angry with suspicion will first begin to speak and only then clap his hand.
