A BBC report has come out that new facial scanners that detect lies far more accurately than the polygraph tests. These facial scanners pick up changes in heat, movement such as wrinkling of noses, swallowing, blinking, and changes in breathing, even to spotting the swelling of blood vessels in the retina. They are going to be employed by security services and in airports to increase detection of suspicious behaviour.
This new camera system is based on work done by Professor Hassan Ugail of Bradford University. He is confident that the new system will be accurate 90% of the time. However it detects people in high stress situations where they are fearful or distrustful. This might indeed mean they are lying. Or not.
As I pointed out in the posting “Botox Stops You Reading People”, a powerful way to spot people’s intentions is to monitor your own facial expressions. Since we humans are profoundly imitative, you are likely to be micro-mirroring the person you are talking to in your own facial expression. When you want to check out what’s going on, focus on what your face is doing.
Vital when you are negotiating a valuable deal or interviewing a senior executive position.
