Polygraph testing, commonly referred to as a lie detector test, is a scientific technique that measures and records physiological responses such as blood pressure, pulse rate, respiration, and electro dermal activity. These physiological indicators are monitored while the subject is asked a carefully structured series of questions designed to elicit specific responses.
At the heart of this process is the expertise of the polygraph examiner. These highly trained professionals possess a deep understanding of human behaviour, psychology, and the intricate workings of the polygraph instrument. The polygraph examination process involves meticulous preparation, including a pre-test interview to establish a baseline for the subject’s typical physiological responses. During the test, the examiner carefully observes and analyses the subject’s reactions to relevant questions, comparing them to their baseline responses. After the examination, the data is thoroughly analysed, and a comprehensive report is prepared, detailing the findings and the examiner’s professional opinion.
