The “itchy scratchies”

When a liar’s autonomic nervous system goes into overdrive, the increased blood flow and expanded capillaries often cause an itching sensation. This is why someone who is telling a lie may suddenly scratch the skin on his head, face, neck, or arms.

Here we see O.J. Simpson scratching his face after Catherine Crier asked him a probing question. This was yet another body language signal that may have indicated that Simpson was not being forthright in his answers.

In his interview with Oprah Winfrey, Lance Armstrong exhibited a major case of the “itchy scratchies” after Oprah asked him why he had sued the people who had accused him (truthfully) about his doping. He immediately got the “itchy scratchies” on his chin and lower jaw. His scratching reflected that he clearly knew that what he had done was very serious and very, very wrong. His body knew it was wrong, too. As soon as the topic was brought up, those changes in his blood flow (remember the autonomic nervous system?) created an itchy sensation on his chin, which he automatically scratched.
