Technology is being developed that claims to be able to tell if a person is lying. “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. Another is meant to work from across the room, even if you do not wish to cooperate.”
