Most people obtain their polygraph "knowledge" from researching the internet, watching television shows... reality shows, court shows, talk shows, dramas and soapies. In most cases these exams are staged for the cameras, producers and the audience, and are NOT REAL POLYGRAPHS.

Here are some things you should know about polygraphs and why they are often not reliable when done for television / Media:



Polygraph exams can not be done in front of an audience.
Polygraph exams must be done in a controlled environment with no distractions
Polygraph accuracy drops as you add more questions (there is usually a limit of 3 to 4 relevant questions permitted per exam)
Polygraph answers are limited to "yes" and "no" (narrative answers are not allowed)
Polygraph questions are spread out so that reactions have time to dissipate from the previous question (the average time between questions should be 20 to 25 seconds)
Movement by the examinee causes distortions with the test results (if the examinee is moving around or talking during the exam, reliable data can not be collected)
Polygraph exams must be done at least 3 times before a decision can be rendered (each question must be asked at least 3 separate times during the procedure)
Polygraph exams take 60 to 90 minutes or longer if done correctly (most TV shows will not allow that much time for an exam)
Polygraph questions must be objective - about facts - not about opinions or feelings
Surprise questions are not permitted (all questions are reviewed before the test)


Are polygraph tests on television real? Sometimes they are, but most of the time they are not.

When a highly qualified examiner conducts polygraphs for television, the exams are done off-camera before the show and can take several hours. The examiner may then re-enact a small portion of the exam for the audience, so what you see is never an actual polygraph.

Unfortunately, most so-called examiners working for television provide 20 minute exams, ask a dozen questions, and give results that are no more accurate than flipping a coin. Any producer who actually cares about the quality of the test and the results will allow the examiner to spend sufficient time with the person tested (up to several hours) and will limit the number of questions to three or less (per exam) to maintain overall accuracy.

Most producers are only interested in getting a test done in the shortest amount of time and the smallest budget possible. Don't believe everything you see on television, and don't expect an examiner to provide a test like you see on television. That is not reality.

We have done numerous appearances on radio and TV.
This is done for general public information and awareness and perhaps for the effect in a scene. Do not expect an examiner to do test for yourself or a company with lists of questions as you see on the movies. You expect high accuracy and reliability and that is what we promise to give you.
