How can I read a Polygraph Test?

Reading a polygraph test involves analyzing the physiological data collected during the examination, which typically includes measurements of heart rate, respiratory rate, and galvanic skin response. Each of these metrics is plotted on a chart, where spikes or changes may indicate stress or deception. A trained examiner interprets these patterns in conjunction with the subject's responses to questions, looking for inconsistencies or emotional reactions. It's important to note that polygraph results are not definitive and should be considered alongside other evidence.
