Quote:Not true. Anything quantifiable can be a scientific test.
How many "false positives" were there last year at CIA?
How many "liars" took and passed the test?
Quote:Now I'm not a scientist, but I believe there are in fact methods in research which identify potential weaknesses in a particular methodology.
DODGE!!
Quote:With your admission the ANS is correlated to "lying", what else does it include?
Never said it wasn't. I said "lying when answering a question" is only one possiblity. Here are others:
Anger (This dumbass polygrapher keeps telling me I'm lying but I'm telling the truth).
Fear (I'm not gonna get the job if I can't get this guy to believe I'm telling the truth!)
Also, (internal dialog) "there's that question again, the one he say's I'm reacting to, but telling the truth. He keeps changing it so it won't bother me, but I know it's just another permutation of the original question. Damn! This is bugging me!...etc."
Of course, the ANS is largely controlled by the "unconscious", not the conscious mind. The unconscious is the seat of a person's memories and fantasies. So there is a whole myriad of reasons for a ANS reaction, other than deception, that is.
Quote:Probabilities, based on numeric evaluation. Please pay attention to previous posts.
Numerical evaluations? What numerical evaluations? In statistics, probability theory is applied to QUANTIFIABLE data.
How do you know if you pass somebody who was lying, or fail somebody who was truthful?
Quote:"Knowing" something and having an extreme probability there is a connection, are similar in nature.
Well, how do you KNOW there is an "extreme probability" I am lying.
