Control Question Tests by Police and Laboratory Polygraph Operators on a Mock Crime and Real Events
Abstract
Males and females truthful or deceptive, about a real life embarrassing story or a laboratory mock crime were examined with Control Question detection of deception tests. Exams were conducted either by a police or a laboratory trained polygraph operator. Subjects were more reactive to event relevant questions when deceptive than when truthful. Police scored subject records more towards innocence whereas laboratory investigators scored them more towards guilt. This was especially pronounced with SRR measurement on embarrassing stories. Such a result could mean that laboratory investigators when mistaken would have a tendency to classify innocent people as guilty when dealing with real events whereas the police when wrong would tend to classify the guilty as innocent.
