How Polygraphs Work

Polygraphs operate by measuring physiological responses that are believed to be associated with stress and deception. During a polygraph examination, the subject is connected to sensors that monitor heart rate, blood pressure, respiratory rate, and galvanic skin response. These measures are recorded on a chart, allowing the examiner to analyze patterns indicative of deception.

The test typically begins with a pre-test interview, during which the examiner establishes baseline physiological responses by asking non-threatening questions. This baseline serves as a reference point for interpreting responses to more critical questions. The examiner then asks a series of questions, mixing relevant inquiries about the specific issue under investigation with control questions designed to elicit a physiological response.

Interpreting polygraph results requires skill and experience, as physiological responses can be influenced by factors unrelated to deception, such as anxiety, fear, and medical conditions. The subjective nature of interpretation, along with the potential for false positives and negatives, underscores the need for caution when using polygraphs as a tool for truth verification.
