Chapter 1: History of Detecting Deception

There have been many theories about detecting deception. Some of the more interesting ones include the following:

  • In ancient Babylon 3,000 years ago, it was believed that a liar would look at the ground and rub his or her big toe around in a circle.
  • The Prophet Isaiah believed that you could look in people’s faces and tell whether or not they were telling the truth.
  • The Ancient Chinese believed that the food in someone’s mouth would remain dry if they were telling a lie.
  • Native Americans would place a hot knife blade on the suspect’s tongue. If it stuck the person was being deceptive.
  • An Italian, Lomborso, theorized that when you put a liar’s hand in a jar filled with fluid it would overflow as the volume of the hand increased due to rising blood pressure.
