The first lie detector, known as the polygraph, was invented by John Augustus Larson in 1921. It measures physiological responses such as heart rate, blood pressure, and respiration while a subject answers questions, based on the premise that deceptive answers trigger distinct physiological changes. Larson's invention was a significant advancement from earlier devices and laid the groundwork for modern lie detection techniques. Despite its use in law enforcement and other fields, the accuracy and reliability of polygraph tests remain controversial.
