FBI File of Lie Detector's Creator

George Maschke writes, "It appears that the FBI considered William Moulton Marston (1893-1947), who invented the lie detector and created the comic book character Wonder Woman under the pseudonym Charles Moulton, to be a 'phony' and a 'crackpot.' He is alleged to have misrepresented the result of a study he conducted for the Gillette razor company in 1938, for which he reportedly received some $30,000, a handsome sum in those days. Despite these misgivings, the FBI today uses Marston's creation (the polygraph, not the Lasso of Truth) to guide investigations as well as to screen applicants and employees.

      Lie detectors aren't often used in court because they're easily inadmissable - my psych teacher was saying the percentage of false positives with them is almost higher than the percentage of correct answers in some cases. Typically since they go off the relative stress/anxiety of the person compared to when the test starts it's sort of ridiculous anyways. If someone is worried about something their tests will become skewed, if they think about something that worries them it can become skewed. If they are (purposefully or otherwise) stressed when the test begins, and suddenly all their answers are calm, it looks like they aren't lying. It's also completely useless testing a whole menagerie of people who express unusual reactions to stress and lie, for example, someone who lies compulsively doesn't become more stressed worried they'll be caught, so it has absolutely no effect on them - on sociopaths and things like them it has no effect because they don't care about the conseqences of being caught lying in court and so aren't stressed by them. Also, any person with the slightest prior knowledge of lie detectors knows they only have to force themselves to think about something stressful to them when they want to be caught lying, and to think about something relaxing to them while uttering something they want to be true - with some practice or even natural aptitude to it they're totally ineffective. Pretty sure Canada practically never uses them unless it's to confirm already known evidence to prove the person a liar more than to get answers out of them.

      You could tell the courts that the FBI thinks the inventor is a nutjob, but if you knew that much about the inventor of the polygraph they'd probably know better than to use the results of such a test as proof for anything in a court - probably true for US courts as well.

      That is just a misrepresentation of how a lie detector works. They are only ~80% accurate, take a long time to perform, and do not work on sociopaths (another ~4% of the population). But they do work, especially the galvanic skin response test. This is because your emotions are tied closely to your sympathetic nervous system. And your sympathetic nervous system also controls your sweat glands. Sudden emotional changes will be registered unless you are a sociopath. The difficulty is the interpretation (which as I said above is about ~80% accurate). But 80% is a useful number for an investigator if you have several people you can test and none of them have been diagnosed as being sociopaths.

      It can't be used in court, but it can be used to find out the truth. To say otherwise is to ignore the 80% success rate. Take 10 willing people and you will almost definitely find out what happened.

      Sorta. The polygraph is more than a prop though.

      It allows the administrator to see reactions that are not physically apparent and make inferences from this.

      The reactions can be detections of lies or stress or a natural bodily function.

      This is where the grandparent had meant that you have to be a trained psychologist to administer and score these exams.

      Note: I am on a clinical track for psychology as well as having gone through one of these with the secret service (I believe the FBI only gives these if you are under an investigation or applying for them). The SS guy had background in criminal psychology. I asked. I was facinated by the exam and it wasn't going to affect my employment one way or the other as I had been guarenteed the job and this just meant more work for me the more clearance I received.

      Like all psychological exams, you need to be able to recognize the baseline items. There is a lot of proven science in these exams -- though one has to employ IRT (Item Response Theory) and you can't just throw the questions off the cuff as happens in the movies. But the baseline questions are the most important and the better trained administrators will actually keep recentering with these questions as you go along. One of my first baeline questions was asking my name. A little known fact outside of my family is that my parents did not name me before I left the hospital as there was disagreement over the name. My mother wanted to name me after my father, he refused because of fears that I'd simply be called Junior and it would stick. What people call me and what my drivers license says are different than my true name, even if this is only family legend and they've never called me this.

      So when answering this baseline question, I simply made myself believe this and doing so comfortably, yet answered positively that what they had stated was in fact my name, while believing otherwise. This threw off the center for the rest of the test. Of course, bad faith items lie all over for a properly calibrated exam (not the instrument being calibrated, the exam). You have to do this for other items, but if you don't believe it as much as your other baseline false negatives, you will slowly center back to your natural truthful range. Beyond this, its easy to project that the person had simply asked you a similar but different question and answer that one. Okay, not easy to do it naturally, but you can with practice.

      Of course, I've seen exams where they are employing true IRT and adaptive branching in the question selection where the idea is to check for bad faith examinees.

      When I took my exam, the examiner had mentioned that I was either the most honest person that he had in quite a while or had cheated. Gotta say, I answered most of the difficult questions 100% accurately and only blew the baseline in the case I'd need to avoid the question. I actually didn't feel any could implicate me on anything, so I went ahead and answered. For instance the questions of "have you ever stolen more than $100 in office supplies from an employer" I gave the answer that gave me a reprimand in that I responded "Over the life time of working, in a month or all at once" and then before he could verbally reprimand me as you are only to answer yes or no to these types, I smiled and stated "Yes..."

      That was the worst one and he let me know that too was a baseline and meant nothing (of which I figured anyways...its too broad a topic as I stated).

      All in all, this isn't a theatrical play for the gullible. The guilty are under no circumstances forced to take these. Remember our right to not self-incriminate. Even where these are legal, you have to give consent. I am confident I could pass no matter what, but I would never accept doing one in a criminal case as there is a matter of interpreta

Besides which, the only way I can be right all the time next week is to learn what the errors are in my thinking this week!

      For the polygraph tests, I was working on the basis that a polygraph test is a known quantity. The confidence limits on accuracy, repeatability and process are well-established and well-defined. They also already have the equiptment, experience in using it, etc. fMRI lie detection is a relatively unknown quantity, the confidence limits are - ergo - much broader. Starting from the statement "at most it admits the polygraph is less accurate", it is not obvious how to compare the two. At what point does something become less accurate, when you're dealing with distributions and not point values?

      There are many ways to do this, but here's two. The easiest approach, if you have enough data, is to find the ranges that give you the same confidence limits - preferably 1% or 0.5%, as anything above that is absurd. You pick the worst end of the range for the fMRI and the best end of the range for polygraph tests. In order to absolutely, firmly, definitively say that fMRI actually is better than polygraph, the polygraph's upper limit has to be strictly below the lower limit for fMRI - otherwise, there is a non-zero possibility that polygraph tests are superior to fMRI. (Not just in some specific case, but in general.) Because courts presume innocence and because lies are more harmful than truth is helpful in investigative work, it's better to assume the least accuracy than the greatest accuracy. That means we now pick the lower limit for polygraphs as being the effective merit of the results. Given the absurdly wide margins there must be for fMRI, if we assume polygraph's limits are below that, the lower limit for polygraph has to be very close to zero.

      (If the limits overlap, even to the smallest degree, then replacing all polygraph systems with fMRI would be stupid, as it would be impossible to be sure if that was making things better or worse, at vast cost. Nobody, not even some of the Government agencies I've dealt with in the past, could possibly be so stupid. So, if they made such a move, despite the gigantic spread of bounds for fMRI and assuming the choice was rational, it would seem that we can deduce the worst-case for polygraph would mathematically need to be very close to zero.)

      The second method, which assumes some data but nowhere near as much, is to take the average expected reliability of the test and place the lower bound at two standard deviations below that. We don't even need to know the values for fMRI for this, we just need to know them for polygraph tests. Two standard deviations would be enough to cover the majority of meaningful cases and lop off all of the tail-end extreme or unusual situations. My guess is that the lower bound for polygraph tests, using this rather crude method, would again be perilously close to zero. This is easier with very little data (you need the mean and either the variance or the standard deviation), but it's harder when working with raw data because at no point do you know if you've calculate

Some corporations still require this for top executives, although they try to keep the practice quiet and make sure execs sign waivers stating the test is voluntary and does not influence the hiring decision (yeah right).

If he has no legal basis to fire you, not hire you, or discredit you, he can use a lie detector as a way to implicate that you are a liar. Since the results of a polygraph are tantamount to biorhythms, there is no way to effectively dispute the results. If you get your own polygraph expert to interpret results to say that you werent lying, then the results are declared 'inconclusive' which still holds the implication.

      Bear in mind that no one really knows what the hell they are measuring with the thing.

      As I understand it, it displays activity in specific regions of the brain. So while somebody is answering a question, you can watch for changes in activity. The most useful areas to watch would be the creative areas of the brain; someone answering questions purely from recall will be working a different region of brain than somebody building and maintaining a fictional story.

      This is slightly more difficult to defeat than a lie detector. Lie detectors mainly measure stress (possibly modern ones use additional biometrics such as perspiration), so if you can consistently cause yourself stress (e.g., bite your tongue), everything you say will register as a 'lie', rendering the machine useless for its intended purpose (i.e., to differentiate truth from falsehood). To extend that to the fMRI, if you can keep your creative processing areas active when delivering answers, your lies will be indistinguishable from truths.

      Causing the device to be unreliable is almost as good as masking a lie as truth.

And naturally those would include studies showing that when several operators are provided a video tape of the subject's answers and the output of the polygraph, they invariably agree 100%.

      The very basis provided for the polygraph to work is screwy. For them to work, a polygraph test would have to distinguish between the fear/stress of being found out vs the fear/stress of not being believed and the potential consequences of that. Further, in some cases it would also have to distinguish the natural stress of being accused of doing horrible things.

      The one claim I do find at all creadible is that the machine acts as a stressor to help a skilled interrogator. It's unfortunate that most polygraph operators aren't skilled interrogators.

While Burt's arguments raised concerns, they were not ultimately persuasive. (bold added by me)

      Regardless, even the original article uses weasel words like "Despite the increasing number of questions over the validity of fingerprints" without any sources to back these statements up (except for a law professor and the few defense lawyers interviewed for the article who - amazingly enough - were attempting to use a "fingerprints are no good" defense).

      Actually, that article does discuss how the judge in question decided that fingerprints are not as reliable as he'd believed before. Which indicates that he'd reviewed evidence, come through an analysis, and found conclusions different from the conventional professional wisdom among judges.

      I remembered the original story flying around at the time, which indicated that there was no actual science underlying the late-1800s emergence of fingerprints as unique identifiers, nor any rigorous science since then proving them. When I read this lie detector story, I thought I'd revisit the fingerprint story to see whether a few years had produced some legitimate claims of science underlying fingerprint evidence, but I found none.

      That's why I reported in my post that fingerprints are "questionable", legitimately, because I found no scientific basis, and a trustworthy analysis finding questions about them. If you can find the science establishing reliability of fingerprint evidence, I'd love to hear it. That would be a lot more reassuring than the current status.
