How to Build the Perfect Lie Detector
By Andrew Crawford, Marketing –
Can you imagine a world in which everyone told the truth, the whole truth and nothing but the truth? Robert Sczcerba of Forbes Magazine recently wrote how the world is heading in that direction with the quest for the perfect lie detector.
There have been many technological advances with lie detectors in the last 100 years, mainly with the invention of the polygraph machine, which peaked in the 1980s.
Unfortunately, recent research shows that the polygraph isn’t as accurate as once advertised, reporting that the test is hardly more precise than flipping a coin. There are many countermeasures that people employ to hide the truth during a polygraph test.
The Brain Game of Lie Detectors
Another technology that has surfaced more recently is that of functional magnetic resonance imaging (fMRI), a more advanced technology that measures the activity in your brain and shows changing patterns of cerebral blood flow and neuron activation.
In other words, an fMRI can determine which side of your brain you are using when you are telling a story or answering questions. If the fMRI shows you are using a certain part of your brain, it can indicate that you are most likely fabricating the story, since that particular part of the brain is linked to creativity and fantasy.
Even still, an fMRI test is both far from perfect and incredibly expensive. An even newer product, EyeDetect™, is the most effective technology to enter this market in years. With 85 percent accuracy for pre-employment and periodic employee evaluations, it is more accurate than any other technology currently on the market.
Developing a New Method
EyeDetect is the latest solution for lie detection developed by Converus, Inc. It tracks and scans subtle movements and changes of a subject’s eyes while a computer quizzes them on true/false questions. This technology eliminates the potential for a subject to “cheat the system” and also eliminates the highly expensive and intrusive procedures of former lie detection technologies.
This product is definitely one to keep an eye out for and surely will become a major factor in the worldwide lie detection market.
