Polygraphs have major flaws. Are there better options?
Polygraphs face scrutiny over reliability and accuracy
George W. Maschke's experience with a failed FBI polygraph in 1995, despite a prior security clearance, spurred him to investigate the reliability of polygraphs, leading to the creation of AntiPolygraph.org. His findings, supported by scientific research, highlight significant flaws in polygraph testing, including high rates of false positives and negatives, which undermine their use in law enforcement and security clearances.
