 Some absolutely fascinating new technology is now being used in some police departments across the country. It is science that plants might look a whole lot like science fiction. The goal though is to determine if the eyes lie. Infrared lights are calibrated to a person's eyes and then the computer takes over. This is always the moment of truth. To see if he's lying or telling the truth. The computer said that you were deceptive on the number six, please be the number six. There we go. The company, Conversus, is bringing a new type of lie detection to the world. It's called eye detect. In that little five minute test, we took about 30,500 measurements of your left eye and 30,500 measurements of your right eye. Researchers at the University of Utah created this test in the early 2000s, partially funded by federal tax dollars. How it's being used is what's new. We need to screen candidates to make sure that the officers that are out there to protect us have not committed crimes in their past that would disqualify them to be an officer of the law or a corrections officer. Pardons and parole officers are also checking it out to use on criminals. The test is based on pupil dilation. Eyes do dilate. That's one of the physiological reactions we do have when we're lying or scared or any other kind of emotions that affect the body. Patrick O'Berke of the American Polygraph Association has evaluated it for 18 months. Which is it's somewhat less intrusive because we don't place components on a person's body. It simply looks at and looks at the pupils of the eyes. How good is it? Invalidation trials, eye detect had 85% accuracy. We're told that the test takes approximately 30 minutes and the results are ready within 5 minutes. Wow.
