What is a polygraph test and how does it work
A polygraph test, also known as a lie detector test, is a scientific method used to measure physical and physiological changes in the body, such as blood pressure, respiration, and perspiration, that occur when a person is asked questions. The test is conducted by a trained professional using a highly specialized instrument that records the changes in the body. The polygraph test works on the principle that lying cause a certain amount of stress, and this stress produces changes in the body that can be detected and measured. However, it is important to note that the polygraph test is not always accurate, and its results should always be interpreted with caution. As such, it is just one tool that can be used to aid in the investigation of a particular case.
