Lie Detector (TV series)

Lie Detector was a British television program that used polygraph examinations to attempt to determine the truthfulness of individuals being interviewed. The show aired on Channel 5.

The premise of Lie Detector centered on members of the public, sometimes involved in disputes or suspected of wrongdoing, voluntarily submitting to polygraph tests conducted by a professional examiner. The examiner asked a series of questions, the answers to which were then analyzed using the polygraph machine's physiological measurements (e.g., heart rate, blood pressure, respiration, skin conductivity) to assess if the subject was being truthful or deceptive.

The results of the polygraph test were then revealed on camera, often to the subject and other parties involved in the situation. This reveal formed a key part of the show's dramatic tension. The program often featured emotionally charged scenarios and personal stories.

It is important to note that the accuracy and scientific validity of polygraph tests are highly debated. The results are not admissible as evidence in many courts due to concerns about their reliability and potential for error. Critics argue that the show may have presented a misleading impression of the accuracy and scientific basis of polygraph examinations.
