Why Do Organizations Conduct Pre-employment Polygraph Tests?

How Does a Polygraph Test for Employment Work?

The polygraph machine used in the polygraph test evaluates physical indicators to detect deception in individuals. Polygraph tests work based on the theory that people exhibit certain responses when lying. These “responses” refer to changes in physiological activity like breathing and perspiration. Other indicators measured on the polygraph test include heart rate, skin conductivity, and pulse rate. Before the polygraph test for employment starts, test subjects must fill a questionnaire. Although the questions are often similar to the ones answered during the initial application, they are more comprehensive. Once the individual completes the questionnaire, polygraph testing commences. Our specialist from Lie Inside Truth will connect the applicant to the polygraph machine and ask questions based on the answers given on the questionnaire. During the exam, the specialist notes his impressions about the individual. The specialist combines his impressions with results from the polygraph machine to form an expert opinion of the individual’s honesty.
