Polygraph
A polygraph, commonly known as a lie detector test, is a tool used in law enforcement and security screening to assess the truthfulness of a person's statements. It works by measuring and recording several physical responses like heart rate, blood pressure, breathing rate, and skin conductivity while someone answers questions. In job contexts, it's often required for positions that need high security clearance or handle sensitive information. While not 100% accurate, it's widely used as part of comprehensive background screening processes, especially in police departments, federal agencies, and some private security firms.
