Since its invention in 1921, lie detector testing and its accuracy have always been a controversial issue in both the scientific and public domains. In fact, despite the popularity that it has gained in the cultural realm over the years, the veracity of polygraph tests continue to plague our endless search for truth.
Xenophanes once said, “Pure truth no man has seen, nor shall ever know.” While there may be some truth in this statement, man’s search for truth did not waver. Since the beginning of civilizations, man has struggled to distinguish the lies from the truth of his very existence and since then, techniques have been invented and reinvented to sought out the truth and weed out the lies.

Relevant information on the examinee and the facts about the case surrounding the examination are gathered and studied and action plans are created before the actual testing is conducted. Once completed, the actual lie detection examination can start.
Lie Detector Testing is subdivided into three different stages: The Pre-Exam Interview; The Polygraph Exam; and The Post-Exam Interview. This is typically administered by a professionally trained and certified polygraph examiner or polygraphist using a computerized, state-of-the-art polygraph technology in a comfortable and climate-controlled office.
The first stage of polygraphic lie detection test is the Pre-Exam Interview. During this stage, the purpose of the examination is made clear to the examinee. This stage is where the examinee is advised of his rights, including the constitutional rights to obtain a legal counsel or express involuntary to undergo the examination. It is also during this stage that the examinee is asked for his version of the story and made aware of the questions as well as the procedure and instruments that will be used in the actual polygraph examination. Once all of these are done, the polygraph components, usually consists of sensors purported at collecting, measuring, and recording physiological data, are attached to the
