Narco and polygraph tests in India
Narco and polygraph tests in India: An Uttar Pradesh government spokesperson said a polygraph test and narcoanalysis would be conducted as part of the investigation into the Hathras murder case.
Tests will be conducted on all parties to the accused and aides, with the exception of the police and other persons involved in the case. The polygraph test depends on whether the body’s response to sleep is different from any other person. Metals such as cardio-cuffs or sensitive electrodes are attached to a person and variables such as blood pressure, heart rate, changes in respiration, sweat gland function, blood flow, etc are measured. Each answer is given a numerical value to determine whether a person is telling the truth, deceptive, or uncertain. Narcoanalysis, by comparison, is a drug injection, sodium pentothal, which attracts a state of addiction or relaxation, where the idea of the subject does not change and they are expected to reveal factual information.
The drug referred to as “truth serum” in this case was used in large doses as anesthesia during surgery and is said to have been used in intelligence operations during World War II. However, none of these methods have been scientifically proven to be 100% effective and they are controversial in the medical field.
