Body language can reveal if someone is lying, with signs including avoiding eye contact, stiff facial expressions, closed body language, and adding too much detail. Liars may also try to distract and cover their mouth or nose. A real smile involves movement in the whole face. Liars may try to distract with objects or movements, and may speak softly or add unnecessary detail. Changing the subject can reveal a liar, while yawning and stretching can be signs of trying to appear relaxed.
There are many ways that a person’s body language can give you clues as to whether or not they are lying. Research has shown that people lie every four minutes of every day and may not even be aware they are doing it. People who lie often avoid eye contact, have a stiff facial expression, and exhibit closed body language. They often try to distract the people they are talking to and can add too much detail to their stories. Members of police departments and security experts use these clues to track down criminals during interrogations.
One of the biggest signs that a person is lying is that they avoid eye contact during conversation. He may also constantly touch his face, covering his mouth with his hand very often. It is also said that touching or scratching one’s nose is a sign of distraction to hide falsehoods. A person who doesn’t tell the truth may try to make you focus on his actions rather than his words.
When a person lies, his physical expression is often very rigid and limited. If he smiles while speaking, only his mouth will move. A real smile involuntarily causes the mouth, eyes, forehead, cheeks, and jaw to move.
The movements of the liar’s hands, legs and arms are towards his own body; takes up little space. The person’s body language is closed. Liars don’t seem relaxed, even though they may be trying to look relaxed.
When a person is lying, they have many ways to distract you from the false statement. Liars may move around the room and place objects between you and them, such as a book or cup of coffee. They will feel uncomfortable facing you and looking directly at you when they speak and may turn their head and body away. An innocent person usually goes on the offensive, while a guilty person goes on the defensive.
When explaining something, a liar may insert more detail into the conversation than necessary. He will usually be uncomfortable with pauses or silences. The person may speak softly or in slurred speech. However, a highly skilled liar is able to speak directly and confidently; salespeople are good at this technique.
If you suspect someone is lying, abruptly change the topic of conversation. The liar will gladly change the subject with you and become more relaxed. A person who is telling the truth will usually be confused by this sudden change. Another sign that someone is lying is yawning. The person may try to look as relaxed as possible, and yawning and stretching are ways to achieve this.
