Understanding Polygraph Lie Detection Tests

During a series of questions, a polygraph, or lie detector, detects physiological changes. These variations in heart rate, blood pressure, and perspiration levels indicate deception. Polygraph machines record physiological responses, which examiners can use to determine truthfulness.

Polygraph tests assume physiological changes occur when people lie. It connects examinees to machines using body sensors. The examiner interprets machine-measured physiological responses while answering questions. Deception can be indicated by large baseline deviations.

Lying activates the “fight or flight” response, changing physiological parameters and enabling lie detection. These involuntary, hard-to-control changes may indicate deception. Polygraph tests are used in criminal investigations, employment screenings, and personal matters despite their limitations.
