🎯 What Is a Lie Detector Test and How Does It Work? Ever wondered how a lie detector test actually works? 🤔 Also known as a polygraph, it measures physiological responses—like heart rate, blood pressure, breathing, and sweat—to determine if someone is telling the truth or lying. The idea? Lies cause stress, and stress triggers physical changes in the body. 🔍 But are they 100% accurate? That’s still debated. Learn more about how polygraphs work and why they’re used in investigations and interviews. 👀 https://tracepointindia.in/lie-detector-test-polygraph-services-gurgaon #tracepointindia #gurgaon #forensicscience #liedetectortestingurgaon #corporatesecurityservices
