The US Home Ministry has warned the employees that polygraph test will be used to prevent government confidential documents from leaking.
Home Minister Kristi Noem said that the employees will have to undergo this test at all costs. Assistant Secretary of Home Ministry Tricia McLaughlin has confirmed this.
She said that the Department of Homeland Security is an agency related to national secur ity. We can, should and will conduct polygraph test of all employees.
During the polygraph test, it is seen whether the person is lying or telling the truth while answering the questions. Whenever a person lies, his heart rate, blood pressure, changes. Sweating occurs. Sometimes, during a polygraph test, attention is also paid to the movement of hands and feet. However, four things are usually observed during the test on a polygraph machine.
- Breathing Rate.
- Pulse Rate.
- Blood Pressure.
- How much sweat is coming out (Perspiration).
How does a polygraph test work?
During a polygraph test, four or six points of the machine are connected to the chest and fingers of a person. Then some general questions are asked. After this, questions related to crime are asked. During this, the person’s heart rate, blood pressure, pulse etc. are monitored on the screen of the machine. A medical test of the person is also done before the test. Then his normal heart rate, blood pressure, pulse rate etc. are noted.
When the test begins, questions are asked. Then if the person answering lies, then his heart rate, blood pressure, pulse rate decreases or increases. Sweat starts appearing on the forehead or palms. This shows that the person is lying. These signals are recorded at the time of every question. If the person is speaking the truth, then all his physical activities remain normal. When a person gives a false answer to a question, a P300 (P3) signal comes out of his brain. In such a situation, his heart rate and blood pressure increase. These are compared with normal rates. It is immediately known whether this answer is true or false.
