Police and intelligence agencies around the world have, for almost 100 years, used the polygraph, a lie-detector test, to help catch criminals and spies. But, now, researchers in Britain and the Netherlands have developed a new method, which is correct (in tests) over 70% of the time. Police stations around the world might begin using this new method within ten years. It doesn’t monitor movements in the face, talking too much or waving arms – all signs that someone is lying. The new method monitors movements in the whole body, which can show that the person is feeling guilty.

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
