The Lie detector is a way to catch lies but it also has its limitations. Most research has estimated the accuracy of polygraphs to be between 80 and 90 percent. It is also said that real-life lies are not tested in the experiments that have been done to catch lies. Lab tests are mostly tried on such people who are well above the level of health and intelligence. Such research rarely covers criminals, children or people with low intelligence on average. In such a situation, the polygraph test can be trusted only in an ideal situation. Let’s get well knowledge about the Lie Detector Machine.
