The Polygraph Test:
Pune Police have sought court permission to conduct a polygraph test on the accused in the Ketan Agarwal murder case, as such tests require the accused’s voluntary consent under Indian law.A polygraph test (popularly called a lie-detector test) is an investigative diagnostic procedure that continuously measures and records a subject’s physiological indicators during questioning. It operates on the core psychological premise that conscious deception triggers distinct, involuntary autonomic stress responses that deviate from an individual’s truthful baseline.The aim of a polygraph test is to generate investigative leads, verify or dispute a suspect’s alibi, and narrow down lines of inquiry.
