What is Polygraph lie Detector Test
The polygraph, often known as a lie detector, is a device that takes physiological readings as a person is asked and responds to a series of questions, including blood pressure, pulse, breathing, and skin conductivity. Deceptive replies to polygraph questions will result in physiological reactions that can be distinguished from those linked to truthful answers when administered by a qualified and experienced polygraph examiner.
How accurate is a Polygraph Lie Detector Test
Currently, there are roughly 25 research papers on the reliability of polygraph exams accessible. Researchers have found it particularly challenging to evaluate the accuracy of polygraph examinations in “real world” situations since the “ground truth” requirements are frequently absent. For instance, it is impossible to locate a representative sample that would allow one to conclusively determine who is and is not speaking the truth. Experts estimate the accuracy of polygraph exams performed by a qualified examiner to be about 90%, and with the newest training, procedures, and equipment up to 98%, based on the research now available. Studies have also indicated that the examiner’s level of expertise and experience is a key factor in the examination’s correctness.
