Lie Detector for Humans Might Beat Out the Court System
As our understanding of nature is increased, the comprehensibility of the world around us is
improved. This includes the human mind. As we understand the workings of the human mind more,
it will be easier for us to deal with some of the mysteries and problems that confront us. One such
mystery is how to tell if someone is lying or not. The bigger problem is one of determining truth and
falsehood, guilt and innocence in our courts of law. We spend billions of dollars on the current system
and we clearly still make many mistakes.
Eventually technology will give us better means for determining the truth in a reliable manner.
Various advances are already taking place in terms of security cameras, interrogation room cameras,
DNA evidence and improved fingerprinting techniques. Some police departments are bottling
atmosphere from a crime site in order to be able to detect the scent of the criminal and compare it to a
As we begin to understand the functioning of each part of the brain, it should be possible to use a
brain scan during questioning in order to determine the credibility of the evidence being stated by a
witness or suspect.
Some might compare such brain scans to the old-fashioned reading of emotions with a lie detector. A
lie detector, which measures the galvanic skin response of a human, may be fooled if the subject is able
to fake emotions much like an actor is able to. It would be far more difficult to fool a complete brain
scan in which patterns of deception are bound to differ from patterns of truth telling. The system will
no doubt start out with a simple pattern recognition scheme and be improved as the knowledge of the
human brain increases.
When such techniques become more reliable than our standard courtroom procedures, how long will it
take us to switch over to using technology rather than judges and juries to determine the guilt or
innocence of a suspect?
Here is an article in the Washington Post about coming lie detectors:
Brain on Fire Joel Garreau: Brain on Fire
Thanks to functional Magnetic Resonance Imaging (fMRI) techniques, it is becoming easier to detect
lies. The Siemens Magnetom Trio at the University of Pennsylvania is a 10-foot-tall, 14-ton fMRI
machine. It may be the most formidable lie detector ever built. By peering directly into our brains,
its may set a very high standard for the recognition of honesty in humans.
The following two firms seem to be in business. The main hesitation would be the high cost, but as
technology progresses, certainly the price will come down.

Will the use of such machines change the face of military and police interrogation?
