Has anyone compared the validity of the results of a poly vs the results of infrared?
To begin with I don't think there is any validity regarding the poly nor has any study been done to test the poly to that effect. Correct me if I am wrong.
Second I believe the infrared method or pupil dilation (different lie detection techniques) is no different than a poly. They all work under the assumption that spiked autonomous nervous system reactions, flushed face, or dilated pupils are indicators of deception. I think they are all garbage. IMHO.
