Narco Analysis: A technique for solving crimes through medical science

You may have come across the term 'Narco Analysis' in crime news.

- Dr. S.M. Shashidhar

When traditional investigation methods fail to uncover the truth in serious criminal cases, police often turn to this scientific technique. Narco analysis, also known as the 'truth serum' test, is not just a procedure but a sophisticated method rooted in medical and psychological principles. It aims to dive deep into the suspect's mind to extract the truth. The term 'narco' comes from the Greek word 'narke,' meaning 'numbness' or 'stupor,' as the process induces a trance-like state.

What is Narco Analysis?

Narco analysis involves using a drug, such as sodium amytal, to put a person into a semiconscious state. Normally, when someone lies, they use their imagination to twist the truth. In this altered state, the person's ability to fabricate stories is neutralized, making it harder to lie. They tend to respond based on memories rather than deception. While in this state, individuals may not speak spontaneously but can answer simple, specific questions. Their responses are considered reliable because they lack the ability to manipulate answers.
