How Accurate is a Polygraph Exam?

The current polygraph research indicates that when a specific single issue polygraph exam, when conducted by a qualified, trained, and experienced polygraph examiner and is properly administered, the accuracy rate is between 90% and 92%. The truth is, DNA, fingerprints or handwriting analysis are not 100%. The polygraph is the most accurate tool available today that assists in validating the truth.
