American Polygraph Association president Milton O. "Skip" Webb, Jr. appeared with Doug Williams, author of
"How to Sting the Polygraph" on ABC News'
Sam Show webcast on Friday, 2 March 2001. To view the half-hour show, go to

President Webb has previously declined to state how polygraph examiners should handle subjects who understand the trickery on which polygraph "testing" depends (See my questions and his replies at
http://antipolygraph.org/read.shtml#informed-subjects)
During the course of the
Sam Show, President Webb made several dubious claims, and I challenge him to either support or retract them here (I will notify Mr. Webb of this challenge by e-mail):
Quote:Skip Webb: "There's a... a wealth of research that clearly shows that polygraph is in the neighborhood of 90 plus percent accuracy upwards to 98 percent accuracy."
Challenge to APA President Skip Webb: list all studies published in peer-reviewed scientific journals that purport to establish the validity of the control/comparison question technique under field conditions. (Hint: as of 1998, there were only four, and they do not establish that the procedure works at better than chance levels of accuracy. See Chapter 8 of David T. Lykken's
A Tremor in the Blood: Uses and Abuses of the Lie Detector, 2nd edition, pp. 133-35.)
Quote:Sam Donaldson: Skip, what about this? Some other emotion other than a lie is engendered when you ask me a question and you read it as a lie?
Skip Webb: Well, first of all, we do an extensive pre-test interview with the individual. We make sure that the room itself, that the interview itself, and that the protocol that's followed prior to the actual testing does away with those types of things that Mr. Williams is referring to. We're gonna make sure that there are no outside noises. We're gonna try to do it in a private setting. We're gonna try to explain in great detail the instrument. So we're gonna take away a lot of that anxiety of doing something new and foreign. If you were taking that test, what you would find, Sam, is that by the time you go through that hour or so pre-test, we've explained all of the instrument functions; we've explained the questions that we're going to ask; we've gone over those questions to ensure that there are no communications problems or misunderstandings; we've given you an opportunity to vent those frustrations or emotions or anger or fear that Doug was referring to. So the test is not done in a vacuum. It's not done by simply walking you into the room, attaching you to the instrument, and conducting a test. Those things we take care of in the pre-test.
Skip Webb failed to mention that in the pre-test, the explanation of the procedure provided to the examinee is false and misleading. (See pp. 42-44 of
The Lie Behind the Lie Detector.)
Challenge to APA President Skip Webb: Prove that the pre-test procedure you described prevents polygraph examiners from "reading as lies" physiological reactions arising from causes other than deception. Cite peer-reviewed scientific research to support your arguments.
Quote:Skip Webb: ...in the federal government, both the Department of Defense and in other areas of the government, we do not make any decision based solely on the adverse results of a polygraph. So no adverse action is every taken on anyone based simply on the results of a polygraph....
Mr. Webb's claim that "no adverse action is ever taken on anyone based simply on the results of a polygraph" is untrue. Applicants for employment with federal law enforcement agencies such as the FBI, U.S. Secret Service, and the Drug Enforcement Agency are routinely denied employment based simply on a "failed" polygraph "test." Eleven plaintiffs have pending lawsuits against the government for this very reason. (See filings in
Croddy et al. v. FBI et al. and
John Doe #6 et al. v. FBI et al. at
http://antipolygraph.org/read.shtml#litigation)
In addition, the FBI launched a massive espionage investigation against former Special Agent Mark E. Mallah based solely on a "failed" polygraph "test," ruining his career, even though he was eventually cleared. (See his statement:
http://antipolygraph.org/statements/statement-002.shtml.) And hundreds of CIA employees have reportedly had their careers put on hold because they "failed" a polygraph "test."
Challenge to APA President Skip Webb: The American Polygraph Association motto is "Dedicated to Truth." Your assertion that no adverse action is ever taken against anyone based simply on the results of a polygraph is untrue, and you know it. Show your dedication to truth by contacting Sam Donaldson of ABC News to correct yourself. (Whether or not you choose to do so, you can rest assured that I will be contacting him.)
