Mrs. Covert’s Spying Lesson #3 : Detecting Lies |
| One of the most important skills you can have as a spy is learning to recognize a lie. Dr. Paul Ekman, Professor of Psychology, in the Department of Psychiatry at the University of California Medical School, San Francisco, is a specialist in recognizing deception. He doesn’t detect lies by the words used, but by noticing what he calls “micro-expressions on people’s faces.” A micro-expression lasts about 1/25th of a second. Regular expressions last half a second up to several seconds. A micro-expression indicates that a person is thinking more than would be normal in that situation. A micro-expression is a sign of distress. https://www.scientificamerican.com/article/humans-are-pretty-lousy-lie-detectors/ Here’s an article on Dr. Paul Ekman’s website: Deception Detection in which he not only gives tips for recognizing lies, he also talks about how to set up conversations to prevent lies, and instead seek understanding.

The P 300 effect is the name for the fact that most people react 300 milliseconds after seeing a picture of something they recognize. The Brain Fingerprint machine consists of a band of electrodes that goes around the head and a computer screen that briefly flashes pictures that are neutral, pictures that are familiar to the person who is being tested, and pictures that would only be known to the criminal and those who are investigating the case. Evidence from this machine has been accepted in courts of law and has been used as grounds for a new trial or for proof of innocence.
