4 facial expressions that show a person is lying

Many people claim that they can tell if someone is lying by listening to their “guts” and experts think that “gut reactions” are uncanny accurate judgments based on nonverbal cues we can see.

Facial asymmetry

Our bodies don’t often listen to our words and it’s possible to tell if someone is lying by studying their noticeable asymmetry. For instance, when someone smiles to express their joy or happiness but they are sad, their eyes can tell the opposite. If the eyes look like they are about to cry despite a wide smile, then that person is definitely lying.

Lip biting

As they say, “lips don’t lie” and psychologists study lip movements as an indicator of stress during lying. When someone bites their lip at the center or the side, they do this to comfort or stop themselves from saying something, probably the truth. In this instance, biting the lip can be a suppressing action, especially if accompanied by raised eyebrows or wide eyes.

Dilated pupils

Pupil dilation is another useful indicator of lying and enlarged pupils are considered a sign that someone is making up a reply. Pupils enlarge when the brain is working hard, so if they get bigger, someone is trying hard to match tell a different story from the truth.

Frequent swallowing

When a person is anxious, they often look for something that can distract them and a common solution is to swallow something, maybe food or drink. Frequent swallowing, therefore, is another indicator that someone is lying because they feel stressed or anxious.
