  • In a ‘narco’ or narcoanalysis test, a drug called sodium pentothal is injected into the body of the accused, which transports them to a hypnotic or sedated state, in which their imagination is neutralised. In this hypnotic state, the accused is understood as being incapable of lying, and is expected to divulge information that is true.
  • A polygraph test is based on the assumption that physiological responses that are triggered when a person is lying are different from what they would be otherwise.
  • A polygraph test does not involve injecting drugs into the body; rather instruments like cardio-cuffs or sensitive electrodes are attached to the suspect, and variables such as blood pressure, pulse rate, respiration, change in sweat gland activity, blood flow, etc., are measured as questions are put to them.
  • A numerical value is assigned to each response to conclude whether the person is telling the truth, is deceiving, or is uncertain.
  • In recent decades, investigating agencies have sought to employ these tests in investigation, which are sometimes seen as being a “softer alternative” to torture or “third degree” to extract the truth from suspects.
  • However, neither method has been proven scientifically to have a 100% success rate, and remain contentious in the medical field as well.
  • In ‘Selvi & Ors vs State of Karnataka & Anr’ (2010), a Supreme Court Bench ruled that no lie detector tests should be administered “except on the basis of consent of the accused”. It said that the ‘Guidelines for the Administration of Polygraph Test on an Accused’ published by the National Human Rights Commission in 2000, must be strictly followed. The subject’s consent should be recorded before a judicial magistrate, the court said.
