WOODLAND HILLS, Calif., Oct. 25 /PRNewswire/ -- "Almost no human being
can beat a polygraph test," says Dr. Louis Rovner, a noted psychologist and
polygraph expert in Woodland Hills, California. In fact, lie detection
technology has become so sophisticated that a polygraph can now detect a
person's efforts to try to beat the test.
In a recent Deputy Sheriff Magazine article, Dr. Rovner writes that there
are several books and pamphlets available on the internet which claim to teach
people how to beat a polygraph test. None of these, he says, can do what they
claim.
Dr. Rovner feels that the idea of beating a polygraph test after reading a
short book is absurd. "This is about the same as saying that you will be able
to perform a Beethoven Piano Concerto at Carnegie Hall by simply reading a
book about piano playing." The interplay between the sophisticated technology
of the polygraph, the experience of the examiner, and the involuntary
physiological reactions of the subject is so complex that almost no one can
look truthful on the polygraph when he is actually lying.
"Beating the polygraph," says Rovner, "is impossible for most people."
The polygraph is a scientific instrument which records physiological changes
in our bodies. Polygraph examiners are trained to look for subtle
abnormalities in these changes as a person answers a series of questions. The
changes, he says, are involuntary reactions that occur in our bodies when we
are not being truthful. "In order to beat the test," he says, "a person must
use his central nervous system to override the involuntary activity of the
autonomic nervous system, and he must do it on cue, every 25 seconds or so."
Given the anxiety of a typically polygraph subject, it is extremely unlikely
that anyone could successfully fool the polygraph.
Scientific research into polygraph accuracy has been going on for more
than 40 years. "Overall," says Dr. Rovner, "we are confident that polygraph
tests have a 96% accuracy rate when done properly." That statement is backed
up by hundreds of research studies and experiments. Rovner's own published
research shows that people cannot beat a polygraph test simply by reading
about it.
