Mattel markets a product called a Magic 8-Ball that has about the same validity as a lie detector as does the polygraph. But the Magic 8-Ball has the advantage that, unlike the polygraph, it is not susceptible to countermeasures. With a manufacturer's suggested retail price of $5.99, for the amount paid to polygraph manufacturers in FY 2004, the US Government could have obtained some 58,000 Magic 8-Balls at retail prices, roughly enough for every federal investigator to have his or her very own personal lie detector/truth verifier. No doubt, even more Magic 8-balls could have been obtained with a wholesale discount.
