Detractors of the polygraph call lie detection a voodoo science, saying that polygraphs are no more accurate at detecting lies than the flip of a coin. "Despite claims of 'lie detector' examiners, there is no machine that can detect lies," reads a statement from the American Civil Liberties Union (ACLU).
Apr 14, 2023 · More recently, researchers have been harnessing the potential for AI to detect lies. In 2021, scientists from Tel Aviv University developed a new AI-powered lie detector that measures micro facial expression in people to determine the authenticity of their statements.. According to researchers, the technology delivers a 73 percent success rate, compared to humans who can spot lying roughly 54 ...
Jan 14, 2020 · It does work much of the time. Typically, when someone is lying, a well-trained polygraph examiner can tell. It is not 100% accurate though. The American Polygraph Association is the world's ...
