The researchers believe their work could be useful for security agents and juries, but of course it’s far from foolproof. It’s also impossible to know for sure whether the courtroom verdicts are right, and if the “liars” being examined are definitely being dishonest. This is a problem for all lie detection; Polygraph tests, which measure stress in response to questions, have similarly variable results. Though they have roughly 85% accuracy when testing guilty people, some polygraph tests have just 56% accuracy for innocent people.
研究者们认为,这项成果可以帮助保安和法官,但依旧做不到高度准确。当然,想要彻底弄明白法庭审判是否公正,或者正在受审的撒谎者是否真的在说谎,这根本不可能。对所有的谎言测试来说,这都是个问题。测谎仪(通过测试受审者的压力)的结果也是多变的。即使测谎仪在测试犯罪人员时的准确率有85%,但对于无辜的人,测谎仪的准确率只有56%。
The truth is, we all behave slightly differently when we’re dishonest, and there’s no definitive telltale sign that unmasks all liars. But the University of Michigan research can help build a picture of dishonesty.
事实是,撒谎时,我们表现的都会略有不同,并没有绝对的迹象能够使我们揭露骗子。但密歇根大学的这项研究依旧可以帮我们构建一幅撒谎者的画像。
