About the lie detector We are sure that the same question marks appeared in the minds of many people after watching the videos.

Well, a professional liar, their reactions and feelings Is he such a bad liar that he can’t control himself?

Before we answer these questions, we need to talk a little about the machine.

There is a new addition to our lives, which are becoming more and more dependent on machines. Dates back almost 3000 years methods for lie detectionremains valid to this day. But there is something we have missed: a human can also beat a machine.

We are in the digital world and everything is at our fingertips. He can find answers to everything and can easily cope with certain situations. We can develop a response. How is it possible nowadays to detect whether someone is lying, based solely on bodily reactions?

In our opinion, not so much.

From ancient Greece to thousands of years old China, there are many things you would never think of. The lie detection method was tried. So what was the result? A big disappointment. Because there is no method in the world that can detect lies with 100% accuracy.

In the early 20th century, what we know as the lie detector was invented polygraph appeared. Responses such as breathing, blood pressure, heart rate and sweating of the person connected to this machine are measured. Starting with easy questions, the questions are directed to the more difficult questions, related to the subjects one wants to learn.

Even our muscles, including all internal organs It is connected to our nervous system. Everything you can think of, such as facial blushing, heart rate, sexual arousal, also falls under the autonomic nervous system.

The polygraph detects that the person is lying. stimulation of the autonomic nervous system looks and detects. While it is expected that a person will sweat or increase his heart rate while lying down, there is also a situation that is ignored: our body can deceive us.

Every person accused of lying already experiences these reactions, at least to some extent.

In addition, a person’s personality traits, reactions in everyday life, anxiety and mood should also be taken into account. So this The accuracy of the machines is not fully possible. Instead, researchers found that using drawings to detect liars would produce more accurate results.

According to this method person who liescreates more monotonous, undetailed drawings without going into too much detail.
