“lie
detectors” are machines that are designed to determine from
physiological signs wether someone is telling the truth. Recent
advances raise the possibility of creating lie detectors that are
far more sensitive than those we currently have. Developing these
new and improved lie detectors can prove extremely
useful.
First, the
new lie detectors promise to virtually eliminate cheating current
lie such as sweating, faster heartbeat or faster rate of breating.
Which generally accompany lying. The problem is that many people
can cheat this system by learning to control their reations and not
showing any of these bodily signs of lying. The new lie detectors,
however, will work by scanning the brains of subjects and measuring
the brain activity that accompanies lying. Because people cannot
hide their brain activity, they will not be able to cheat on these
tests.
Second, the
improved lie detectors would provide results that could be used as
evidence in court.>>>>>>
A third
benefit would be that research on the new lie detectors technology
could help scientists develop relate
technologies.>>>>>>
