Researchers are going to introduce eye-watching lie-detector software that can spot liars more accurately, with 82.5 percent accuracy.

At present, police get 65 percent accuracy.

It was checked in 40 interviews with unpaid assistants, some of those participants were trying to hide the fact they had hidden a cheque.  To set a ‘baseline’ a retired police officer questioned the participants on different topics.

Ifeoma Nwogu of the University at Buffalo, State University of New York,  says that the researchers will repeat the conduct test with larger samples.

‘We know that the eyes give signals that lead to deception, but what about general body movements?’ said Nwogu.

Retired FBI counter-intelligence special agent Joe Navarro said in an interview with Scientific American:

‘One problem with this research is its over reliance on the face as the only place to evince information from the body.’

‘I can tell you as an investigator and somebody who’s studied this not just superficially but in depth, you have to observe the whole body; it can’t just be the face,’ added Navarro.
