Marty,

Thank you for the clarification!

No one is arguing here that props (including the polygraph) cannot be useful in interrogations. But as the National Academy of Sciences noted in its report, there is essentially no evidence on the additive validity of polygraphy (its ability to add predictive value to that which can be achieved by other means). And as Dr. Fienberg pointed out, the handful of purported successes of the polygraph that Kyle McSlarrow adduced are of no statistical value.

Polygraph screening is a fraud, as more and more of us who are or have been subject to it are learning. As Dr. Richardson has pointed out before, continued polygraph screening would require such a universal bluff as to be impractical over the long term.

Do you agree with Kyle McSlarrow's stated plan for continued reliance on polygraph screening?
