 A new kind of polygraph test, making it hard for people to lie to police. It's called the eye detect and instead of tracking perspiration, blood pressure, it uses a test that tests the subjects' eyes. Experts say it records minute dilations of the pupil that a human eye just can't catch. When a person is in a position they have to lie, the cognitive load is great to the point where the person then has to make a decision. Do I tell the truth? Do I lie? Do I tell the truth? Do I lie? And they finally make that decision. So they lie at that point. People dilate. Did you know that? Yeah. I'm going to be looking at those pupils. Evan say the eye detect is about 85% accurate, all in its own. It's about 98% accurate when it is used with the traditional polygraph test. There's something to this. I'm like a good friend of yours. Well, because you always tell me when I'm fibbing that you can see something around. They sparkle. Right. Tell me right now you're a billionaire. I am a billionaire. They sparkle. There's something to this, apparently. It should be a polygraph test. I know. As little as you know. You better be careful.
