Scientists have discovered a new way to identify whether or not someone is telling the truth.
In the classic Disney film Pinocchio, the wooden protagonist has the unfortunate affliction of having a nose that grows in length every time he tells a lie. While the signs aren't quite so obvious in humans, it turns out that our noses do increase in temperature when we lie, a change that can be observed using thermographic equipment. This is the conclusion of a pioneering new study that set out to explore changes in temperature around the human body in connection with psychology.
Known as the "Pinocchio Effect", the thermal changes see both the area around the nose and part of inner corner of the eye increase in temperature. The team also found that anxiety increases facial temperature while concentration reduces it.
"When a person lies, they experience a "Pinocchio effect," which is an increase in the temperature around the nose and in the orbital muscle in the inner corner of the eye."
