Well, Nancy, I think the fact that there are three different polygraphs that this young girl has taken and three different results tells you a lot about the unreliability of polygraphy.
There is broad consensus amongst scientists that polygraphy has no scientific basis, and the National Academy of Sciences concluded in a 2002 research review that “polygraph testing's accuracy in distinguishing actual or potential security violators from innocent test takers is insufficient to justify reliance on its use in employee security screening in federal agencies.”
The idea behind polygraphy is that physiological changes often accompany lying.
Mr. Lundell, who owns a polygraphy business in nearby Medford, Ore., typically spends three days a week with convicted sex and violence offenders in Klamath Falls.
It beats self-reporting -- simply asking parolees whether they've violated their parole terms -- a method previously employed by many jurisdictions that have switched over to post-conviction polygraphy.
Polygraph proponents argue that this is a benefit the ongoing polygraphy debate misses: The question shouldn't be whether the technology is always accurate, they say, but whether it is useful.
When it comes to dissuading released offenders from relapsing, polygraphy is superior to other methods, adherents say.
Calling his work "40% science and 60% art," Mr. Lundell says the key to polygraphy is asking the right questions.
Polygraph testing "will become a standard for supervising probationers of all kinds," says Mr. Holden, who was one of the first to use polygraphy with sex offenders in the early 1980s.
Polygraphs have long been used as a tool to keep sex offenders from relapsing, typically as part of maintenance programs that combine polygraphy with group therapy and parole-officer supervision.
