If you want to expose your interlocutor, pay attention to some signs during the conversation.
Of course, they are not 100% proof of lying, but a combination of factors will help you figure out what motives a particular person is pursuing and whether he or she is lying at the moment.
Nose
A shrunken, so-called “rabbit” nose is a clear sign that a person does not like something at the moment.
Lips
When something is bothering us, we tend to unconsciously purse our lips and suck and bite them when we are nervous.
Cheeks
If you notice that the person in front of you runs his tongue along the inside of his cheek, this may indicate that he is nervous.
Neck
If the neck is tilted, it means that your opponent is relaxed. But when this tilt disappears, it may indicate a problem has arisen.
By the way, sometimes when lying there is a need for additional air. For example, men can often ventilate their necks – this indicates that they are feeling anxious.
Shoulders
If your interlocutor hears a question to which he does not know the answer, both of his shoulders quickly rise.
