Polygraph Recordings

Polygraph recordings are the data collected during a polygraph test, which measures physiological responses such as heart rate, blood pressure, breathing rate, and skin conductivity. These responses are recorded on charts as the individual answers questions, with the goal of detecting stress or lie-related reactions that might indicate deception. The recordings provide a visual representation of the body's involuntary responses, which can then be analyzed by examiners to assess the accuracy of the person's answers. While commonly used in investigations or security screenings, polygraph results are not universally accepted as definitive proof of truth or lies.
