It promises to be the most formidable lie detector ever built. By peering directly into our brains, its keepers aim to set a new gold standard for the recognition of honesty in everyone from politicians to criminals to lovers...The problem may be finding customers:
In the pipeline are several cheaper, faster, easier-to-use brain-examining technologies, all intended as major improvements on the unreliable chicken-scratching polygraph we use now. Some seem to identify mental preparations for telling a lie even before the liar opens his mouth -- verging on mind-reading.
