no sugar coating,
You write:
Quote:The cost to the community by matching hiring practices with McDonalds would be far more expensive in the long run than paying for a poly test at taxpayer expense.
You provide a
false dilemma here. The choice that law enforcement agencies face in setting hiring policies
is not one of either relying on polygraphs (or CVSA) or matching McDonalds' hiring practices. The choice for such agencies is whether to rely on methodologies that are known to be completely invalid, cause injustice to individuals, and are readily susceptible to countermeasures, or to abandon them.
Quote:But since I had nothing to hide and told the truth, my results were favorable and showed no deception.
Whether one passes or fails a polygraph "test" has no clear relationship with whether one has anything to hide or has told the truth. As explained in Chapter 1 of
The Lie Behind the Lie Detector, polygraphy has no scientific basis whatsoever. That you passed your pre-employment polygraph examination is more attributable to good luck than to your honesty.
Quote:So for all you who don't like the polygraph, too bad. You have your right to think it is a "voodoo science".
That polygraphy is voodoo science is, in fact, the overwhelming consensus of the scientific community.
Quote:The rest of us have a right to think it is a good tool.
You also have the right to believe in other popular delusions such as
astrology,
tarot cards, and
psychic detectives. But your belief, however sincere, does not make such things "good tools."
Quote:I don't think it is foolproof, but neither is any other part of the background investigation for police officer.
That no part of police officer background investigations is foolproof does not in any way confer any validity to polygraphy, or justify reliance on such nonsense. The argument against polygraph screening is not merely that it is "not foolproof," but that
it has no validity whatsoever.
