The basic idea behind the new method is that liars fidget more and that an all-body motion suit – the kind used in films to create computer-generated characters – will record this. The new method is over 70% reliable – the polygraph is only 55% reliable. In some tests, the success rate of the new method was more than 80%. Ross Anderson, one of the research team, said: “Guilty people fidget more and we can now measure this.”
