The Polygraph: Does It Detect Lies or Rely on Lies?
Amherst, N.Y. (June 28, 2001)-When the FBI announced that it had uncovered
Robert Philip Hanssen's 15 years of alleged espionage activities, the
immediate question was how an organization like the FBI, equipped with the
best investigative tools, could overlook so serious a security breach for
so long. An article by the Center for National Security and Arms Control's
senior scientist, published in the new July/August 2001 issue of Skeptical
Inquirer, suggests that such blunders might be explained by American law
enforcement's love affair with the arcane contraption known as the
polygraph a.k.a lie detector).
Alan P. Zelicoff is the Senior Scientist in the Center for National
Security and Arms Control at Sandia National Laboratories in New Mexico. He
offers a scathing indictment in his article for Skeptical Inquirer, titled
"Polygraphs and the National Labs: Dangerous Ruse Undermines National
Security." Zelicoff compares the polygraph to the ancient Roman practice of
divining the future from animal entrails: "Perhaps polygraphers would do
better with Wonder Woman's lasso than they have been doing with their box.
The secret of the polygraph-the polygrapher's own shameless deception-is
that their machine is no more capable of telling the truth than were the
priests of ancient Rome standing knee-deep in chicken parts."
According to Zelicoff, the four parameters measured by the polygraph-blood
pressure, pulse, perspiration, and breathing rate-are all affected by a
broad range of emotions, and offer no reliable measurement of deception.
Zelicoff says that there are dozens of studies in the past two decades
showing that the lie detector cannot distinguish between truth telling and
lying. As examples of the polygrapher's dangerous inaccuracy, he points to
the cases of spies like Aldrich Ames and the Walker brothers, who passed
their polygraph tests repeatedly every five years. He also cites examples
of those wrongly accused based on shoddy polygraph evidence, such as FBI
agent Mark Mullah whose career was ruined by suspicion, despite the fact
that all "evidence" against him was dismissed and his badge was restored.
"It is time to relegate the polygraph... to the ash heap of bad ideas and
misplaced beliefs," Zelicoff says. The scientist urges that "we should not
make the spy's task easier with self-defeating measures like the
polygraph."
