The word polygraph is derived from the Greek word polugraphos, for “many” (poly) “message” (graph).
A polygraph is a device that measures an individual’s involuntary physiological responses to questions–analyzing differentiations in respiration, heart rate, blood pressure and perspiration–to determine if the individual is being truthful in their answers. The polygrapher uses data recorded by the polygraph to render an opinion regarding truthfulness. It’s important to remember that the machine doesn’t obtain the truth, the polygrapher has the responsibility of rendering an opinion of truthfulness based on the totality of the interviewing and polygraphing process.
There are three potential outcomes that can be offered by the polygrapher:
- There were no significant signs of deception (the subject was truthful);
- There were significant signs of deception (the subject was not truthful);
- The test was inconclusive (an opinion could not be rendered).
Modern polygraph equipment is computerized rather than scanned onto paper, but the measuring devices used today are much the same as years past.
Why use a polygraph? First, there are no known devices or methods of lie detection that are fool-proof. However, the polygraph is considered to be the best tool that investigators can use to solicit the truth. Typically, the polygraph is utilized in one of two ways; to screen for information regarding an individual’s unknown conduct over a period of time (i.e., Have you been involved in criminal conduct since becoming an adult?); or, to test the knowledge of a subject regarding a known or unknown fact (i.e., Do you know the whereabouts of Jane Doe?). Polygraphs used for screening purposes are normally conducted on law enforcement recruit candidates or other government official positions, whereas the latter test is more common in soliciting truthfulness in either civil or criminal cases.
