I was reading an article about the proper ways to deal with children when lying. I found an interesting part of it that stuck out to me with regards to IR.
Barry McManus, who served for ten years as the CIA’s Chief Polygraph Examiner and Interrogator, is one of the world’s foremost authorities on “leakage” - which is the physiological response when you lie (sweaty palms, lack of eye contact etc.) Going further, he notes you have about 50 muscles in your face, and a few involuntarily contract when you are deliberately saying untruths. Also, for what it’s worth, your nose temperature rises.
So could some sort of testing protocol (standard) be adopted for lie detection that is consistent and repeatable? Could we all be possibly missing a very simple application to perform that no one is marketing or doing currently? It would be interesting to see if someone could set up a business in doing this along side a private polygraph specialist.
My biggest question is, how much does it rise? If it is less than 2% of normal human body temperature, or observed temp prior to the lie detection, then a good lawyer could bring in the camera +/- 2% accuracy of the camera to create doubt.
Yet another potential application.
