European Researchers Develop More Accurate Full-Body Polygraph

Posted by Soulskill on from the we-need-a-brain-biopsy-to-confirm-your-story dept.

jfruh writes: Despite their widespread use in industry and law enforcement, traditional lie-detector polygraphs give accurate results only about 60% of the time, barely better than the 55% accuracy people can get just by following their gut instincts. Now researchers in the UK and the Netherlands are trying to improve that. They claim a full-body polygraph based on motion-capture suits used for movie special effects can detect lies with 75% accuracy.

    Exactly. There's no reliable body response for a lie. All they are measuring is nervousness, which you could have for a variety of reasons. It's the same thing the border agent does.

    The purpose of the polygraph is to bully the victim into a confession. The unknowing victim thinks they are undergoing a scientific test, but they are actually being drilled by a skilled interrogator w/ no lawyer present to defuse the loaded questions.
