POLYGRAPH: DOE DECIDES TO SIMPLY REISSUE ITS OLD POLICY. The National Academy of Sciences completed its review of scientific evidence on the polygraph (WN 15 Dec 00). The NAS report, "The Polygraph and Lie Detection" (NAS Press, 2003), found polygraph tests to be unacceptable for DOE employee security screening because of the high rate of false positives and susceptibility to countermeasures. Congress instructed the Department of Energy to reevaluate its policies on the use of the polygraph in light of the NAS report. DOE carefully reevaluated its policies and reissued them without change, arguing that a high rate of false positives must mean the threshold for detecting lies is very low. Therefore, the test must also nab a lot of true positives. Since that's the goal, the DOE position seems to be that the polygraph tests are working fine and false positives are just unavoidable collateral damage. But there is still a countermeasures problem: anyone can be trained to fool the polygraph in just five minutes. WN therefore recommends replacing the polygraph with a coin toss. If a little collateral damage is not a problem, coins will catch fully half of all spies, a vast improvement over the polygraph, which has never caught even one. Moreover, coins are notoriously difficult to train, making them impervious to countermeasures. ------ End of Forwarded Message ------------------------------------- You are subscribed as interesting-people () lists elistx com To manage your subscription, go to http://v2.listbox.com/member/?listname=ip Archives at: http://www.interesting-people.org/archives/interesting-people/
