After interrogating Aftab, the police is searching the forest and the pond. At the same time, to know the truth, the lie detector test of the accused is also being done. Yes, the polygraph test ie Lie Detector Test of Aftab Poonawala, accused in the Shraddha murder case, is being conducted. The first session of this test was completed on Wednesday.

Lie Detector Test: Significantly, the Delhi Police had applied for the Polygraph Test (Lie Detector Test) in the court. The court has approved this application. During the polygraph test, it is seen that it is seen whether the person is telling the truth or lying while answering the questions. During the polygraph test, things like breathing rate, pulse speed, blood pressure etc. are taken into consideration. Let’s know how the lie detector machine works.

How is the polygraph test done: During the polygraph test some things of a person are taken into consideration. Actually, when a person tells a lie, his heart beat, blood pressure changes. He sweats. Also, the eye does not remain stable in one place. In such a situation, during the test, the rate of breathing of a person, the speed of his pulse, blood pressure, and how much he is sweating during the test are taken into consideration. Sometimes the movements of the hands and feet of the person answering are also noticed. During the question-answer, machine points are added on the person’s chest and fingers. First he is asked general questions then he is asked questions related to his crime.

How the truth comes out: When the polygraph test is started, the first person is asked easy and related questions. After this, questions related to his crime are asked. When a person has committed a crime and he is telling a lie, there is some change in his answers and physical symptoms. These changes are seen through the machine and a conclusion can be reached by the way it answers.

What happens when you lie: During the polygraph test, when the answerer tells a lie, his physical activities start changing. At the time of lying, the heart rate, blood pressure, pulse rate of a person decreases and increases. Sweat starts pouring on his forehead. The palms also get wet with sweat. These signals are recorded during the question. It shows whether the person to whom the question is being asked is lying or telling the truth.

How to know that a person is lying: If a person is lying during question and answer, his heart rate, blood pressure, Change comes. Whereas, on speaking the truth, the physical activities of the person remain normal. The same, on telling a lie P100 (P3) signal is output. Due to this signal, his heart rate and blood pressure increase slightly. The increased pressure is then compared to the normal rate to judge whether the answer is true or false. That is why medical examination of the accused is done before polygraph test so that his normal heart rate, blood pressure and pulse rate can be assessed correctly.

Can anyone cheat the polygraph test: Now the question is whether a person can cheat the polygraph test. Significantly, the truth can be detected through this test through physical changes. However, it is not necessary that the results will come 100 Percentage will be correct. On this test Percent cannot be trusted. If a person somehow keeps his heart rate, blood pressure, pulse rate normal while answering questions, then he can easily get away with lying. However, it is highly likely that one will not be able to do so.
