With MRI lie detectors your brain gives you away

Marc Perton

Being able to act calm and collected when telling a whopper of a lie may not be enough to get defendants off in the near future, if a number of entrepreneurs have their way. Several developers are now exploring the use of brain scans using MRI machines as lie detectors. And unlike polygraphs, which rely on emotional indicators that can be masked, the MRI hones in on the source of the lie, in the brain itself. The machine can track the flow of blood into certain areas of the brain, indicating increased activity consistent with lying. One company, Cephos Corp., is being advised by former O.J. Simpson lawyer Robert Shapiro, who says, "I'd use it tomorrow in virtually every criminal and civil case on my desk." So far, however, the reliability of the tests has yet to be proven, and they haven't been used in any court proceeding. And bioethicists worry about the potential of the new technology to "change ... our ability ... to invade what has been the last untouchable sanctuary, the contents of your own mind," in the words of Hank Greely of the Stanford Center for Law and the Biosciences. That's okay with us; we've got nothing to hide. But, just the same, let's test the machines on someone else's head, first. Okay?
