"Guilty parties get hot around the eyes when lying, the team found; naive innocents stay cold1. The group correctly pinpointed over 80 per cent as either guilty or blameless. This success rate is comparable to the existing polygraph method of lie detection, which measures changes in pulse rate, breathing and sweating. "

I take it back. There may be something here. If this claim holds true, an 80% technology could be used for screening. But anything with a large error rate like this cannot be used in court. Terrorist airport screening is a good application if this really works. False positives can be eliminated on further investigation.
