Scientist Organizes Resistance To Polygraphs
George Maschke writes "Brad Holian, a senior scientist at Los Alamos National Laboratory, is using a blog to organize resistance to plans for random polygraph and drug testing of Lab scientists. Holian writes: 'Polygraphy is an insulting affront to scientists, since a committee of the National Academy of Sciences has declared that, beyond being inadmissible in court, there is no scientific basis for polygraphs. In my opinion, by agreeing to be polygraphed, one thereby seriously jeopardizes his or her claim to being a scientist, which is presumably the principal reason for employment for many scientists at Los Alamos.'"
The idea is to convince people to *believe* that the polygraph machine is scientific and will detect their lies so that they're more likely to not lie, or are nervous while questioning, or even don't take the test at all and just spill it beforehand. It's psychological intimidation, kind of like forcing confessions of bad thoughts in a cult environment. That's one reason you see those "you shall not be subjected to polygraphs at work" posters at your job... a nasty employer could really intimidate people (e.g. union organizers) with it.
I don't think this is about work performance at all, rather its about ferreting out people who are more susceptible to being forced into stealing government secrets or who might do so on their own without coercion.
If I have a serious heroin problem, I may get myself into so much debt and other trouble that I wind up being used by some foreign spy group or something (if I worked at Los Alamos of course). Or maybe I don't want my habit getting out and therefore can be blackmailed. That sort of thing. This is similar to how homosexual people have been targetted in prior decades; not because a gay person can't do the work, but because having this secret you really want to keep means you can be blackmailed with it.
Long story short: the polygraph is a pile of pseudo-scientific bullshit, that can be easily beaten by anyone that knows how it works. At its core, its basically just a non-standardized investigation protocol for extracting harmful confessions by deceiving the person being investigated.
After educating myself, I passed a polygraph easily the first time, without any preparation or practice, while directly lying to my investigator. For the record, what they were asking was none of my employer's business (in my opinion). I was previously warned that the average session takes an hour, and can sometimes run into 3-4 hours when there are "complications". However, by manipulating my physiological responses to a few critical control questions, and pretending to be appropriately intimidated and impressed by the investigator and his machine, I was out of there in 15 minutes, which I was later told was something of a record.
From http://antipolygraph.org/:
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 as, "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 testing has 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 against the 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
The guy's right, by the way. For similar reasons, I've walked off jobs because I refuse to be piss-tested. I don't do drugs, I'm an infrequent drinker, nearest to a chemical vice is drinking too much espresso, but as a matter of principle, it's none of their goddamned business. And I've never gone a day without being employed. The only reason not to stand up to the bastards is cowardice, or the all-American tendency to grovel before any authority, no matter how illegitimate or irrational.
