The American Medical Association and the Congressional Office of Technology Assessment have said that polygraphs give a false report as often as 50 percent of the time. A professor of psychology and neurobiology is developing a lie detector that measures brain waves, rather than bodily functions, as do the polygraphs now in use. The American Medical Association and the congressional Office of Technology Assessment have said polygraphs are wrong 15 percent to 50 percent of the time. He claims that it will pick up 70 to 90 percent of those lying, and will falsely accuse no one. But even if we could detect liars with such accuracy, would they be any less likely to lie?
