The Art of Lying
Lying has gotten a bad rap. In fact, it is among the most sophisticated accomplishments of the human mind. But how can one tell if a person is fibbing?
Lying is among the most sophisticated and demanding accomplishments of the human brain. Children have to learn how to lie; people with certain types of frontal lobe injuries may not be able to do it.
Electrical stimulation of the prefrontal cortex appears to improve our ability to deceive. This region of the brain may, among other things, be responsible for the decision to lie or tell the truth.
Most people have trouble recognizing false statements. Some polygraph tests are better at it yet are far from perfect. Researchers are trying to use imaging methods to distinguish truth from lies. Intensified activity in the prefrontal cortex may be an indicator of the process by which we decide to lie or not—but it tells us nothing about the lie itself.
