title: Trial by polygraph: reconsidering the use of the guilty knowledge technique in court.
abstract: Polygraph test results are by and large ruled inadmissible evidence in criminal courts in the US, Canada, and Israel. This is well-conceived with regard to the dominant technique of polygraph interrogation, known as the Control Question Technique (CQT), because it indeed does not meet the required standards for admissible scientific evidence. However, a lesser known and rarely practiced technique, known as the Guilty Knowledge Test (GKT), is capable, if carefully administered, of meeting the recently set Daubert criteria. This paper describes the technique, and argues for considering its admissibility as evidence in criminal courts.
