on PAX Television Channel 'Lie Detector' Aired May 17, 2005 8:00
Bob Heironimus, a 64-year-old retired man
Yakima, Washington, claims the famous 1967 Roger Patterson film of the legendary "Bigfoot"
was all a hoax, on PAX TV's "Lie Detector," airing Tuesday, May 17, 8:00-9:00
Heironimus submitted to a lie detector test administered by leading polygraph
expert Dr. Ed Gelb to try to prove that he was the infamous creature shot on film in Bluff
California, wearing just a modified gorilla costume, which does not match the figure in the Patterson film. Not even close.
Hosted by Rolonda Watts, "Lie Detector" is a provocative series that examines
behind real-life stories ripped from the headlines, using the most powerful
detect deception - the polygraph.
Heironimus took the polygraph on live television and passed the test according to Dr. Ed Gelb, proving once and for all that along with passed polygraphs by serial killers like Ted Bundy, Heironimus believes he was the man in the suit to the degree that he too was able to pass the polygraph.
Is it any wonder the polygraph is not admissible evidence in a court of law?
It is note worthy to mention that Heironimus is unable to produce the alleged costume with breasts he allegedly wore 38 years ago and he was unable to satisfactorly say why he waited all these years to make such an admission.
Additionally, Heironimus footprints do not match
those left by the creature in the Patterson Film and he is unable to duplicate the locomotion of the creature filmed by Roger Patteron in October of 1967. The fundamental nature of Heironimus' statement is phoney. He lied and passed the polygraph anyway, just as serial killer Ted Bundy did all the way down death row to the electric chair.
Polygraph ("lie detector")
"I don't know anything about lie detectors other than they scare the
hell out of people."
-- Richard Nixon
A polygraph is an instrument that simultaneously records changes in
physiological processes such as heartbeat, blood pressure, and
respiration. The polygraph is used as a lie detector by police
departments, the FBI, the CIA, federal and state governments, and
numerous private agencies. The underlying theory of the polygraph is
that when people lie they also get measurably nervous about lying.
The heartbeat increases, blood pressure goes up, breathing rhythms
change, perspiration increases, etc. A baseline for these
physiological characteristics is established by asking the subject
questions whose answers the investigator knows. Deviation from the
baseline for truthfulness is taken as sign of lying.
There are three basic approaches to the polygraph test:
The Control Question Test (CQT). This test compares the physiological
response to relevant questions about the crime with the response to
questions relating to possible prior misdeeds. "This test is often
used to determine whether certain criminal suspects should be
prosecuted or classified as uninvolved in the crime" (American
The Directed Lie Test (DLT). This test tries to detect lying by
comparing physiological responses when the subject is told to
deliberately lie to responses when they tell the truth.
The Guilty Knowledge Test (GKT). This test compares physiological
responses to multiple-choice type questions about the crime, one
choice of which contains information only the crime investigators and
the criminal would know about.
Psychologists do not think either the CQT or the DLT is
scientifically sound, but a majority surveyed by the American
Psychological Association think that the Guilty Knowledge Test is
based on sound scientific theory and consider it "a promising
forensic tool." However, they "would not advocate its admissibility
[in court] in the absence of additional research with real-life
One major problem with this test is that it has no
controls. Also, unless the investigators have several pieces of
insider information to use in their questioning, they run the risk of
making a hasty conclusion based on just one or two "deviant"
responses. There may be many reasons why a subject would select
the "insider" choice to a question. Furthermore, not responding
differently to the "insider" choices for several questions should not
be taken as proof the subject is innocent. He or she may be a
sociopath, a psychopath, or simply a good liar.
Is there any evidence that the polygraph is really able to detect
lies? The machine measures changes in blood pressure, breath rate,
and respiration rate. When a person lies it is assumed that these
physiological changes occur in such a way that a trained expert can
detect whether the person is lying. Is there a scientific formula or
law which establishes a regular correlation between such
physiological changes and lying? No. Is there any scientific evidence
that polygraph experts can detect lies using their machine at a
significantly better rate than non-experts using other methods? No.
There are no machines and no experts that can detect with a high
degree of accuracy when people, selected randomly, are lying and when
they are telling the truth.
Some people, such as Senator Orrin Hatch, don't trust the polygraph
machine, even if used by an expert like Paul Minor who trained FBI
agents in their use. Anita Hill passed a polygraph test administered
by Minor who declared she was telling the truth about Clarence
Thomas. Hatch declared that someone with a delusional disorder could
pass the test if the liar really thought she was telling the truth.
Hatch may be right, but the ability of sociopaths and the deluded to
pass a polygraph test is not the reason such machines cannot
accurately detect lies with accuracy any greater than other methods
of lie detection.
The reason the polygraph is not a lie detector is that what it
measures--changes in heartbeat, blood pressure, and respiration--can
be caused by many things. Nervousness, anger, sadness, embarrassment,
and fear can all be causal factors in altering one's heart rate,
blood pressure, or respiration rate. Having to go to the bathroom can
also be causative. There are also a number of medical conditions such
as colds, headaches, constipation, or neurological and muscular
problems which can cause the physiological changes measured by the
polygraph. The claim that an expert can tell when the changes are due
to a lie and when they are due to other factors has never been
proven. Even if the device measures nervousness, one cannot be sure
that the cause of the nervousness is fear of being caught in a lie.
Some people may fear that the machine will indicate they are lying
when they are telling the truth and that they will be falsely accused
of lying. Furthermore, even the most ardent advocate of the polygraph
must admit that liars can sometimes pass their tests. One need only
remember the spy Aldrich Ames, who passed the polygraph test several
times while with the CIA. This lesson was lost on the FBI, however,
who started requiring polygraph tests of its employees after spy
Robert Hanssen was caught. Heretofore, the FBI had only used the
polygraph on suspected criminals. Apparently, the FBI thinks that
they could have prevented Hanssen's betrayal if only he had been made
to take the polygraph.
In California and many other states, the results of polygraph tests
are inadmissible as evidence in a court of law. This may be because
polygraph tests are known to be unreliable, or it may be because what
little benefit may be derived from using the polygraph is far
outweighed by the potential for significant abuse by the police. The
test can easily be used to invade a person's privacy or to issue a
high-tech browbeating of suspects. Skeptics consider evidence from
polygraphs no more reliable than testimony evoked under hypnosis,
which is also not allowed in a court of law in California and many
other states. Also, in 1998, the U.S. Supreme Court argued that
Military Rule of Evidence 707, which makes polygraph evidence
inadmissible in court-martial proceedings, does not
unconstitutionally abridge the right of accused members of the
military to present a defense (United States, Petitioner v. Edward G.
The American Civil Liberties Union strongly supported the passage of
the Employee Polygraph Protection Act of 1988 (EPPA) which outlaws
the use of the polygraph "for the purpose of rendering a diagnostic
opinion regarding the honesty or dishonesty of an individual." The
EPPA doesn't outlaw the polygraph across the board, however. Federal,
State and local governments can still use the polygraph. The federal
government can give polygraph tests to government contractors
involved in national security projects. In the private sector,
security and pharmaceutical firms can still use the polygraph on
current or prospective employees. Furthermore, any employer can
administer polygraph tests.
"In connection with an ongoing investigation of an economic loss or
injury to his/her business on these conditions: The employee under
suspicion must have had access to the property, and the employer must
state in writing the basis for a reasonable suspicion that the
employee was guilty" (ACLU).
The ACLU supported the EPPA not only because of the lack of evidence
for the accuracy of the polygraph, but because of abuses related with
its administration, including, but not limited to, the invasion of
For example, in order to establish "normal" physiological reactions
of the person being tested, "lie detector" examiners ask questions
that purposely embarrass, frighten and humiliate workers. An ACLU
lawsuit in l987 revealed that state employees in North Carolina were
routinely asked to answer such questions as "When was the last time
you unintentionally exposed yourself after drinking?" and "Who was
the last child that got you sexy?" Polygraphs have been used by
unscrupulous employers to harass union organizers and whistle-
blowers, to coerce employees into "confessing" infractions they did
not commit, and to falsely implicate fellow employees (ACLU).
Why would so many government and law enforcement agencies, and so
many private sector employers, want to use the polygraph if the
scientific community is not generally convinced of their validity? Is
it just wishful thinking? Do the users of the polygraph want to
believe there is a quick and dirty test to determine who's lying and
who's not, so they blind themselves to the lack of evidence? Perhaps,
but there are other factors as well, such as the esoteric technology
factor. The polygraph machine looks like a sophisticated, space-age
device of modern technology. It can be administered correctly only by
experts trained in its arcane ways. Non-experts are at the mercy of
the high-tech, specially trained wizards who alone can deliver the
prize: a decision as to who is lying and who is not.
Another reason for the polygraph's popularity is the pragmatic
fallacy factor: it works! Case after case can be used to exemplify
that the polygraph works. There are the cases of those who failed the
test and whose lying was corroborated by other evidence. There are
the cases of those who, seeing they are failing the test, suddenly
confess. What is the evidence that the rate of correct identification
of lying corroborated by extrinsic evidence is greater than the rate
of identification of lying by non-technological means? There isn't
any. The proofs are anecdotal or based on fallacious reasoning such
as thinking that a correlation proves a causal connection.
On the other hand, it is possible that one of the main reasons so
many government, law enforcement and private sector employers want to
use polygraphs is that they think the test will frighten away liars
and cheats who are seeking jobs, or it will frighten confessions out
of those accused of wrongdoing. In other words, the users of the
machine don't really believe it can detect lies, but they know that
the people they administer it to think the machine can catch them in
a lie. So, the result is the same as if the test really worked: they
don't hire the liar/cheat and they catch the dishonest employee.
