indianexpress.com

Police are seeking consent for polygraph tests in the Siya-Ketan case, a method largely viewed as unreliable for detecting deception. Polygraph tests measure physiological responses like pulse and respiration, assuming lying alters these. Narcoanalysis involves drugs to induce a sedated state. Neither has a proven 100% success rate. In India, these tests require the subject's consent, and refusal cannot be used against them. Information discovered through voluntary tests can be admitted as evidence.
