The Lowell Sun quotes Professor Hank Greely in a story about lie-detector systems:

The company's patience is a virtue, according to Hank Greely, a professor at Stanford Law School and director of the Stanford Center for Law and the Biosciences.

"The fact Cephos has wanted to refine its accuracy before going to market seems to be a good thing," Greely said. "I think it's reckless of No Lie MRI to market given the real questions about the accuracy of the test."

Even if fMRI is proven to be reliable -- Greely believes that in the next 10 to 20 years, we will see "pretty effective fMRI-based lie detection" -- it's unclear how it would, or should, be used.

Right now, most employers are forbidden by law to use lie-detecting devices, a statute that likely covers fMRI technology, Greely said. (Exceptions include many government agencies, especially those that handle issues of national security.)
