Eyes are a lie detector

In the experiment of detecting a lie, most people will pay attention to the eyes of the liar to see if the liar looks directly at themselves. Prolonged and dodgy eye contact are important signs that the other person is lying.

Generally speaking, lie researchers believe that avoiding eye contact, or looking down at each other, or obviously leaning his head to one side, indicates that the person is not honest.

This statement has a certain truth, the liar may not look at you, he is worried that this will increase the sense of uneasiness, so his eyes will look around, eyes wandering.

Indeed, if a person tells a lie, he will be nervous when he looks at others, and then it will be reflected in his eyes. So, liars instinctively shift their eyes to eliminate tension.

Sometimes the judgment of eyes is not so accurate.

There are some cunning people who are good at playing tricks. When they lie, their eyes are still staring at each other tightly. They seem to be so calm and easy. People who lie a lot can do well. Therefore, people who keep their eyes glued to each other are not always honest.

Here's a trick to tell lies from your eyes. No matter how skillful the liar is, he can't cover it up. People's pupils will enlarge or shrink with the change of emotion. This change of pupil is beyond human control, so as long as we observe each other's pupil, we can determine whether he is lying or not.

There is a story in Russia: Kamo was captured by the police in a foreign country, and the Tsarist government asked for his extradition. He will undoubtedly face the death penalty if he returns to Russia. So he pretended to be crazy and tried to escape punishment. His acting skills deceived many experienced doctors, and finally he was sent to a famous doctor in Germany for identification. The expert's final experiment was to put a red hot metal bar on his arm. Carmo endured great pain without any expression of pain, but his pupils dilated. The old expert saw this and fully understood that he was not a lunatic who lost consciousness, but a normal person.

In addition, the direction of the eyes can also help to identify lies.

The direction of the eyes shows the activity of different parts of the brain, which is almost impossible to fake. Most right-handed people use their left brain to look to the right when they recall, and use their right brain to look to the left when they lie. In short, right-handed people look to the left when they lie, and left-handed people look to the right when they lie. This action is an important signal to recognize a lie.
