General Information About Polygraph
The term “lie detector” is a very popular, but misleading, name for the polygraph examination. In Greek, the word polygraph means “many writings.” The polygraph instrument was so named because it makes various simultaneous recordings of physiological changes that occur in a person’s body. In actuality, the polygraph instrument should be called a “truth verifier.” Statistics show that in the vast majority of instances, the polygraph instrument verifies the truthfulness of your statements.
There are many misconceptions about a polygraph examination. For example, it is widely assumed that the polygraph examination is wrapped in secrecy and that its success depends on keeping it secret. Nothing could be further from the truth! Remember, questions are encouraged. The examination you are about to take will be explained in detail by a trained professional polygraph examiner.
The examiner will explain how the polygraph instrument operates, how it records your body’s physiological responses when you lie and tell the truth, and every question to be asked of you in the polygraph examination will be discussed with you word for word.

WHAT DOES A POLYGRAPH CONSIST OF?
PRE-TEST INTERVIEW During the pre-test interview, the polygraphist (polygraph examiner) will explain your legal rights and the voluntary nature of the examination. Also discussed is your medical, physical, and psychological background as well as your knowledge of the investigation and an explanation on how the instrument works.
IN-TEST PHASE At this point the polygraphist will review all the pertinent test questions with you and then conduct a “Acquaintance Test” to help them assess your suitability for additional tests. Several tests will then be conducted which will include the reviewed questions. There will be no surprise questions on any tests. The Polygraph Examiner will then analyze the results of each test to arrive at an opinion.
POST-TEST INTERVIEW During the post-test interview, the polygraphist will talk to you about any lingering thoughts or questions you might have.
WHAT IF I AM TELLING THE TRUTH, BUT I AM NERVOUS ABOUT TAKING THE EXAMINATION?
I HAVE HIGH BLOOD PRESSURE; WON’T THAT LOOK AS THOUGH I’M LYING?
DOES THE TEST HURT? CAN I GET AN ELECTRICAL SHOCK?
No, there is slight pressure from the cardio cuff but the test does not hurt. Also, there is no possibility of you getting an electrical shock.
It is most important that during the examination you be as comfortable as possible. The only discomfort experienced may be a slight pressure on the arm from the blood pressure cuff.
SUPPOSE THE INSTRUMENT SAYS I AM LYING WHEN I AM NOT?
WHAT IF THE INSTRUMENT MALFUNCTIONS?
CAN I BE FORCED TO TAKE THE EXAMINATION?
HOW LONG DOES THE EXAMINATION TAKE?
DOES THE EXAMINATION MEAN THAT THE POLYGRAPH IS INFALLIBLE?
No. Most examinations readily reveal to the polygraph examiner whether or not the person is truthful. Possible outcomes of any polygraph examinations are: Truthful, Deceptive or Inconclusive. “Inconclusive” means the examiner is unable to render an opinion of either Truthful or Deceptive in that particular case. The polygraph examiner may request a voluntary re-examination if the results are inconclusive.
