Contrary to the past when in addition to chart analysis out of chart information such as: case data, examinees behavior clues, and alike, were factored into the decision-making process of a polygraph test conclusion, today’s approach render the decision based ONLY on numerical scoring analysis i.e., quantifying numerically the differences in the physiological responses between the relevant question and the comparison question. This article suggests that due to test’s complexity along with the numerical analysis inherent weaknesses, that affect the decisions outcomes examiners should engage their intuition, which was found to be an accumulated subconscious information gained over life experience, as a quality observer mean in their decision- making process.
