Scientist Organizes Resistance To Polygraphs 405

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.

      Back in the 80's, I was a restaurant manager. At the time I had a theft problem. At one point, some money showed up on one of my employees. I had her take the test and she failed. I ended up firing her, all the while thinking that it could not be her. Turned out that the problem continued and it was somebody else. I fired an innocent gal based on that shit. There is nothing that would convince that that crap works. It is pure voodoo and is absolutely worthless. IMO, you would be better off casting bones then polygraphs. At least you do not subject the person to total humiliation.

      Polygraphs work--sorta [...] 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.

      1) Relying on people believing a lie is bad policy. Especially if some of those aware of the truth (that it's a lie) refuse to take it, and are then fired.

      2) And this 'sorta working' is very unreliable. Even if you know it's a lie, you can still get nervous while taking the test - just because you know that all they are doing is checking how nervous you are. So the tester can't know what a person acting nervous during the polygraph means - could be guilty, could be innocent.

      3) Actually, polygraphs can be used in a scientifically correct manner, but nearly never are. The WRONG way is to ask questions like 'did you kill Mike?' - which make anyone nervous, guilty or innocent. The RIGHT way is to do a randomized statistical test, as follows: say Mike was killed by a shotgun, a fact which only the police know. You can then ask the suspect the following questions: "was Mike killed by a rifle?" "[...] a shotgun?" "[...] a handgun?" "[...] a knife?" etc. etc. Only the killer would know the true weapon, so if your suspect reacts differently to the 'shotgun' question, that would be informative. Of course other elements would also have to be statistically accounted for: you'd need to ask several controls the same questions (just to see that "shotgun" isn't a word that evokes special responses in general); to randomize the order of the questions; to have the person asking the questions not know the answers; and so forth. Basically, to do the same things you'd do in a scientific experiment.

      But this is (a) hard and time-consuming, and (b) not always possible (you need information only the killer would know).

        No, polygraphs are just bullshit, period. There is no scientific way to employ them because they make a fatally flawed assumption: that lying causes increases in vital measurements.

          No, polygraphs are just bullshit, period. There is no scientific way to employ them because they make a fatally flawed assumption: that lying causes increases in vital measurements.

          Common polygraph use assumes that lying causes increases in vital measurements, yes. But notice that what I mentioned in my post was a difference in vital measurements. If you get enough randomized trials, you can conduct a statistical test just like of every other scientific hypothesis.

          Yes, perhaps some people react more to "shotgun", and some respond less. If, out of 100 people, the suspected killer reacts in a not-statistically-significantly-different manner, then that is one thing. But if, on the other hand, he reacts in a unique way, then the odds of that occurring were he not privy to information about the shotgun would be 1% (i.e. the Null Hypothesis is that all 100 people tested are the same, so the chance that a single person has a different result by chance, and that that person is our suspect, is at most 1 in 100 - speaking in general terms).

          Increases in vitals like body temperature, perspiration and heart rate correlate with nervousness, not deception.

          Agreed, which is why an increase in these vitals in a single individual is not enough, by itself, to show anything.

          Furthermore, a suspect reacting to the word "shotgun" is not informative in the slightest. The shotgun from Doom might've just been his favorite weapon in that game. Or he might have some other past traumatic experience with a shotgun. It means nothing.

          As I said above, this is possible, yes - it can occur by chance. But by a correct statistical test, you can check whether the reaction is explainable by coincidence or not. This is exactly the same way surveys are done or experiments in medicine or the social sciences. (Of course it isn't perfect, but then nothing is 100% perfect; the law can convict above a reasonable doubt.)

          Polygraphs are just another interrogation tool to make the suspect feel more powerless and make the interrogator look more powerful.

          Agreed. Polygraphs, as they are commonly used, are useless or worse than useless (dishonest, easily abused, etc.). But what I wrote in the post you are responding to is something completely different.

          A note about the basic science behind this stuff: there is plenty of evidence of bodily responses to familiar stimuli (for example the cognitive psychology literature on 'priming', also electrophysiology, etc.). However, the commonly-used polygraph may not use the measures proven to work. If all it does is test blood pressure and GSR (galvanic skin response), then we may be right to be skeptical (although perhaps research on GSR has improved in recent years - I don't know). However, things like EEG are also non-invasive and easy to test, and research has shown them to be informative about various things. So: even if the commonly-used polygraph is a sham, correct use of science and statistics can be used to devise a better method, and hopefully things will continue to progress in that direction.

    ``* * * to minimize the potential for release or disclosure of
    classified data, materials, or information'' (42 U.S.C. 7383h-1(a).)
    Section 3152(b) requires DOE to ``* * * take into account the results
    of the Polygraph Review,'' which is defined by section 3152 (e) to mean
    ``* * * the review of the Committee to Review the Scientific Evidence
    on the Polygraph of the National Academy of Sciences'' (42 U.S.C.

    So they attached this to one of those emergency defense appropriation bills:
    SEC. 3152. DEPARTMENT OF ENERGY COUNTERINTELLIGENCE POLYGRAPH PROGRAM.

    (a) NEW COUNTERINTELLIGENCE POLYGRAPH PROGRAM REQUIRED.-The Secretary of Energy shall carry out, under regulations prescribed under this section, a new counterintelligence polygraph program for the Department of Energy. The purpose of the new program is to minimize the potential for release or disclosure of classified data, materials, or information.

    (b) AUTHORITIES AND LIMITATIONS.-(1) The Secretary shall prescribe regulations for the new counterintelligence polygraph program required by subsection (a) in accordance with the provisions of subchapter II of

    chapter 5 of title 5, United States Code (commonly referred to as the Administrative Procedures Act).

    (2) In prescribing regulations for the new program, the Secretary shall take into account the results of the Polygraph Review.

    (3) Not later than six months after obtaining the results of the Polygraph Review, the Secretary shall issue a notice of proposed rulemaking for the new program.

    (c) REPEAL OF EXISTING POLYGRAPH PROGRAM.-Effective 30 days after the Secretary submits to the congressional defense committees the Secretarys certification that the final rule for the new counterintelligence

    polygraph program required by subsection (a) has been fully implemented, section 3154 of the Department of Energy Facilities Safeguards, Security, and Counterintelligence Enhancement Act of 1999 (subtitle D of title XXI of Public Law 106-65; 42 U.S.C. 7383h) is repealed.

    (d) REPORT ON FURTHER ENHANCEMENT OF PERSONNEL SECURITY PROGRAM.-(1) Not later than January 1, 2003, the Administrator for Nuclear Security shall submit to Congress a report setting forth the recommendations of the Administrator for any legislative action that the Administrator considers appropriate in order to enhance the personnel security program of the Department of Energy.

    (2) Any recommendations under paragraph (1) regarding the use of polygraphs shall take into account the results of the Polygraph Review.

      • Polygraphs are only effective if you believe they're effective. If you believe that they're a load of bunk, they won't catch shit. I have successfully convinced a polygraph that I was Cleopatra in a past life. That possibility notwithstanding, it really isn't hard to fool a polygraph. I work with cops from time to time with my work, and usually they only use a polygraph to decide whether you are worth investigating: if you agree to the polygraph and act like you have nothing to hide, then there's no point i

    Posting as AC because I have personal experience "cheating" a polygraph test I was compelled to undergo by my employer after reading the lie behind the lie detector [antipolygraph.org].

    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/ [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

    Considering the "brainscan" approach to polygraphs that the future may hold. I am kind of interested in
    how a 100% accurate polygraph or lie-detector would affect civilization. How it would affect law enforcement
    and judiciary. How would it affect business agreements and politics. If a really good lie detector were
    readily available, then what would it do to society, government, economies, education, religion...

      One of the fundamental problems with polygraphs is that there is no such thing as an absolute truth. If one could invent a "100% accurate" polygraph all it would really measure is if the subject believes he or she is telling the truth or not (which is all that current polygraphers claim that it can measure anyways). So, someone that could truly convince themselves that something is true could still fake a pol

    Quite simply, LANL employees' biggest problem is that we aren't unionized. We stand idly by and watch management (LANS/NNSA/DOE) hammer us again and again and again with policies that decrease the quality of workplace life (without adding jack to the real safety and security of the institution). The "substantially equivalent" requirement for benefits between the last contractor and the current contractor has been revealed to be a stinking pile of bullshit. With a strong collective bargaining agreement, there'd be some pushback against this unrelenting spiral into hell. There is none, however, because nearly everyone in Los Alamos County believes that unions are dues-sucking liberal plots that exist solely to protect the slackers and lackwits. Efforts to unionize have been and will continue to be fruitless. And so, things will get worse.

    To specifically address the current outrage, Director Mike Anastasio's plan to expand random drug testing, one can say that it's true that LANL has had far, far too many security and safety incidents over the past decade. But I can't think of a single one in which the cause was traced back to drug use or alcohol overconsumption. This means we'll be spending money that the contractor doesn't have (they're facing a $150M + shortfall this year) to solve a problem that the lab doesn't have, and raping the Fourth Amendment in the process. (Yes, I know the workplace drug laws have been routinely upheld, but when the courts write that some things are too important for Constitutional protections to apply, what're you to think?) THIS is the kind of visionary thinking that made LANS the winning contractor?
