Polygraph Test
Now the question is what is a polygraphy test. Let us tell you that in this process, many physical reactions like blood pressure, pulse, respiration and skin are measured and recorded during the investigation of a person. It is believed that the physical reactions of a person are different from the reactions recorded when he lies. Each reaction is given a numerical value, which concludes whether a person is telling the truth or lying. However, its report is not valid in the court. But it makes it easier for the investigating agency to investigate.

In this test, sodium pentothal, also known as ‘truth serum’, is injected to induce a hypnotic state in the person and deactivate imagination. According to the information, by doing this, the person speaks the truth in an unconscious state of mind. This drug is used in high doses as anesthesia during surgery. Some media reports say that the narco analysis test was used to obtain information during the Second World War. The test is conducted under the supervision of a psychiatrist and questions related to the incident are asked. It is believed that the accused does not lie due to being in a hypnotic state.
