Thermal Imaging Lie Detector In Development 183
beaverdownunder writes with this quote from the BBC:
"A sophisticated new camera system can detect lies just by watching our faces as we talk, experts say. The computerized system uses a simple video camera, a high-resolution thermal imaging sensor and a suite of algorithms. ... It successfully discriminates between truth and lies in about two-thirds of cases, said lead researcher Professor Hassan Ugail from Bradford University. ... We give our emotions away in our eye movements, dilated pupils, biting or pressing together our lips, wrinkling our noses, breathing heavily, swallowing, blinking and facial asymmetry. And these are just the visible signs seen by the camera. Even swelling blood vessels around our eyes betray us, and the thermal sensor spots them too."

Sad, but true. They tried this with an early prototype in 2008. Within 5 minutes it was engulfed in flames and set back the research by nearly 2 years.

Does that mean you might be found 2/3 guilty of a crime, or will they roll a die and send you to prison on 1-4 ?

It will be illegal to use this on politicians.
We already have a visual lie detecting algorithm for politicians: "Their mouth is moving."

... all you have to do is memorize and rehearse lies in advance and imagine them and recall them as if they were memories. People get caught in lies because it's cognitively demanding to make it up on the spot unprepared.
From what I've read, you're supposed to randomly lie or tell the truth on the easy questions they ask at the start to gauge your response.
If you don't believe this consider religious faith. Many people I'm sure believe those falsehoods genuinely because they are well ingrained in their imaginations.
But all my religious beliefs are true; it's only other people's religions that are unfounded.
