Polygraph flaws prompt search for better lie detection

Polygraph tests, used for decades in law enforcement and security clearance, face significant criticism due to major flaws and inaccuracies. Research indicates a high rate of false positives and insufficient true positives, leading to their exclusion from most US courts and limited use by private employers. Despite these concerns, the technology persists, potentially contributing to wrongful convictions and security vulnerabilities. Scientists and corporations are now exploring advanced alternatives, including monitoring eye behavior and brain activity, though the fundamental possibility of accurately detecting deception remains a subject of debate among experts.
