Brain Imaging Ready To Detect Terrorists, Say Neuroscientists

MRI Scans Can Pick Up Lies, But Raise Ethical Issues

Jennifer Wild

Brain-imaging techniques that reveal when a person is lying are now reliable enough to identify criminals, claim researchers.

Critics maintain that the technique will never be useful for such investigations, arguing that, as with traditional polygraph detectors, liars could learn to fool the tests. And researchers in the field have previously admitted that the approach needs more work. But neuroscientists from the University of Pennsylvania School of Medicine in Philadelphia have now told Nature that they believe their test is ready for real-life scenarios.

The main advance is being able to distinguish lies from truthful statements in a given individual. Although previously scientists could see how the brain lit up when people lied, results were based on the averaged brain activity of a group of people and did not look at individual fibs for each person. "Now we can tell when an individual lies on a specific question," says Gur. "This is a major step forward."



Just great maybe we will have these installed at airports so we can get a brain scan before we get on a plane. Remeber though this is an anti-terroism tool so its for a good use.

What if you're having a bad day, will it then "detect" you as a criminal or what?
Personally I think it sucks and is probably not even near as accurate as they claim it is.

The lie detector isn't perfect, but its better than nothing. So if this machine is as accurate as they say then it will be another good tool for law enforcement agencies.

People also complained about DNA testing and Finger Printing too.
