In an 11 November 2026 blog post titled, “The Polygraph (“Lie Detector”) Test: Is It Accurate?” medical doctor and researcher Morton Tavel discusses polygraphy from a scientific perspective. Excerpt:
Presumably possessing an aura of validity, polygraph testing is commonly used in the attempt to detect lies on popular TV crime shows and other media transmissions. Recently the U.S. government investigators have taken the unusual step of subjecting about 50 members of the U.S. military’s staff and civilian employees to polygraph tests in the effort to determine which ones might have leaked classified information to journalists about the Iran war, and this testing was apparently also motivated by an effort to discourage others from making similar disclosures in the future. However, this process raises questions about the general accuracy of polygraph testing.
