Behind the Lie Detector
The dirty little secret behind the polygraph is that the
"test" depends on trickery, not science. The person being "tested" is
not supposed to know that while the polygraph operator declares that
all questions must be answered truthfully, warning that the slightest
hint of deception will be detected, he secretly assumes that denials in
response to certain questions -- called "control" questions -- will be
less than truthful. An example of a commonly used control question is,
"Did you ever lie to get out of trouble?" The polygrapher steers the
examinee into a denial by warning, for example, that anyone who would
do so is the same kind of person who would commit the kind of behavior
that is under investigation and then lie about it. But secretly, it is
assumed that everyone has lied to get out of trouble.
The polygraph pens don't do a special dance when a
person lies. The polygrapher scores the test by comparing physiological
responses (breathing, blood pressure, heart, and perspiration rates) to
these probable-lie control questions with reactions to relevant
questions such as, "Did you ever commit an act of espionage against the
United States?" (commonly asked in security screening). If the former
reactions are greater, the examinee passes; if the latter are greater,
he fails. If responses to both "control" and relevant questions are
about the same, the result is deemed inconclusive.
The test also includes irrelevant questions such
"Are the lights on in this room?" The polygrapher falsely explains that
such questions provide a "baseline for truth," because the true answer
is obvious. But in reality, they are not scored at all! They merely
serve as buffers between pairs of relevant and "control" questions.
The simplistic methodology used in polygraph
no grounding in the scientific method: it is no more scientific than
astrology or tarot cards. Government agencies value it because people
who don't realize it's a fraud sometimes make damaging admissions. But
as a result of reliance on this voodoo science, the truthful are often
falsely branded as liars while the deceptive pass through.
Perversely, the "test" is inherently biased
truthful, because the more honestly one answers the "control"
questions, and as a consequence feels less stress when answering them,
the more likely one is to fail. Conversely, liars can beat the test by
covertly augmenting their physiological reactions to the "control"
questions. This can be done, for example, by doing mental arithmetic,
thinking exciting thoughts, altering one's breathing pattern, or simply
biting the side of the tongue. Truthful persons can also use these
techniques to protect themselves against the risk of a false positive
outcome. Although polygraphers frequently claim they can detect such
countermeasures, no polygrapher has ever demonstrated any ability to do
so, and peer-reviewed research suggests that they can't.
January 2002, retired FBI polygraph expert Dr. Drew C. Richardson reiterated his challenge to the polygraph community to prove their claimed
ability to detect countermeasures
(techniques for passing -- or beating -- the polygraph). His challenge has gone eleven years without any takers. What are the polygraph operators afraid of? (Listen to a personal message from Dr. Richardson.)
CBP Polygraph Statement of "Al"
My name is "Al." I recently took the polygraph examination for U.S. Customs and Border Protection (CBP). I had probably the worst experience ever. I failed based on the assumption of the examiner that I was hiding some serious crime I had committed. I went on and on with this examiner, insistently telling him I had never done anything. I'll call this polygraph examiner, "Mr. D."
