Polygraph Test Results

The examiner determines if a lie has been given based on a comparison between the standards of the person’s behavior, their baseline, and their behavior when they were asked a certain question.  When the examiner has analyzed the entire data gather by the polygraph instrument, he/she can come up with the results, which can either be NDI (no deception indicated), DI (deception indicated) or INC (inconclusive).  The inconclusive result is sort of like a “grey area”, as an anonymous person described on a website about polygraph testing.  This raises a good point because the inconclusive test results allow for people who are not guilty, yet have shown some signs of deception, to not be judged by incorrect test results.
