Detect liars through ... nose temperature

A recent experiment by scientists from a university in Spain has shown that it is possible to detect a liar through . nasal temperature.

The decrease in nasal temperature is due to anxiety when people are forced to lie.

According to Sputnik, during the test, scientists from Granda University (Spain) asked a group of subjects to "lie to their relatives" over the phone.

In addition, volunteers are tasked to monitor the group of participants in this test. With the help of thermometers, they were able to determine the temperature distribution on the face of the researched person.

Specifically, observing on infrared images, scientists found that, if a person tries to lie, the temperature of the person's nose drops by 1.2 degrees Celsius, and the forehead heats up to about 1.5 degrees Celsius. .

According to Emilo Gomez Milano, a member of the research team, the decrease in nasal temperature is due to anxiety when people are forced to lie . In addition, deception increases the screw job, leading to increased forehead temperature.

Mr. Milano also noted that the result is more accurate than 80% of the participants and according to him, this method is 10% more accurate than a lie detector.
