Scientists, psychologists and law enforcement are closing in on liars.

New methods of discovering people who lie or decieve are being studied, developed and implemented. From the lie detector to MRI imaging, science has long been consumed by finding ways to interpret the body’s response when a person tells a lie.

The lie detector measures body responses such as heart rate, sweat volume, blood pressure and respiration, but, as Bill Majeski a polygrapher tells us, the machine can only tell when someone is anxious.

New tests are incorporating the MRI machine to help discover lies. According to Daniel Langleben, a lie can be tracked from the decision by the person to lie via changes in a certain area of the brain. While this test is more accurate than the lie detector of the 20’s, it does require a willing subject — something a true criminal would not be.

Lastly, Mark Frank, a University of Buffalo psychologist is taking the recognition of certain facial expressions to a whole new height in reading a person’s thoughts. Mr. Frank teaches law enforcement personnel how to recognize facial “tics” and interpret the person’s thoughts at the moment it occurred. His work is helping officials search out terrorists and others.

So, liars beware — it’s better to tell the truth!
