Police and intelligence agencies around the world have, for almost 100 years, used polygraphs as lie detectors to help convict criminals or find spies and traitors. But the polygraph could soon be defunct. Researchers in Britain and the Netherlands have developed a new method that has a success rate, in tests, of over 70%. This new method could be in use in police stations around the world within a decade. It doesn’t monitor facial tics, talking too much or waving of arms, which are all signs that someone is lying. The new method monitors full-body motion, which can show that the person is feeling guilty.
When is the new lie detection method expected to work with over 70% accuracy?
It has already achieved this accuracy level in tests Within ten years Once it is modified to monitor movements of the entire body It is currently not known
