The Truth About the Polygraph, According To the NSA

An anonymous reader writes "The NSA (the secretive intelligence agency that brought you wholesale warrantless wiretapping) has produced a public relations video about its polygraph screening program titled 'The Truth About the Polygraph.' But is the NSA telling the truth? AntiPolygraph.org provides a critique (video)."

      Let's say you have a test for a virus that is 99% accurate, but 1% of the time, it gives a false positive (says someone has the virus, but doesn't). Let's also say that there are 1000 people that might be infected, but nobody is sure. All of them are tested, and on average, 10 of them will show up as false positives. That number can probably be delt with, perhaps with a more expensive (but more accurate) test, or maybe the treatment is no big deal (so they can just get an injection and go on).

      OTOH, let's say that 1 million people might be infected. Test all of them and there ends up being 10,000 false positives. Now the costs of the more accurate test start rising. Perhaps the treatment is more dangerous or expensive (rabies shots used to be pretty nasty, for example), so you really don't want to use it on people who aren't really sick.

      So your accuracy rates need to be in line with how many people are going to be screened. If its use is highly targeted, then a test that's 90% accurate might be OK. If it's more of a general screening, then it needs to go into the five-9's kind of accuracy, perhaps more.

      Polygraphs are nowhere near 90% accurate. It's maybe 70% accurate, and has both false positives and false negatives. For general job screening, like the NSA is using it for here, that's nowhere near good enough. It might be good enough for police investigations as a way of seeing if they're on the right track, but there's a reason it's not considered admissible court evidence in the US.

      Of course, all this is only focusing on the basic statistical issues. There's a whole other set of arguments surrounding privacy, which matter even if a future technology is 99.999% accurate.

Voice stress analysis has been used a long time by the intelligence community and I'm betting there are systems available to them that are much more effective than that.

      Most of the technologies that the military and the intelligence apparatus uses that are really innovative are kept away from public view. They are paid for from a "black" budget that has been estimated to be as high as 200 billion dollars. I remember reading an article about a couple of think tanks that tried to back into the amount that is spent "off the books" by the government in secret projects and there were estimates that put it to more than half of the amount that we spend on publicly reported military projects.

      I would also guess that some of the technologies that become available to industry and become publicly known are already 20 years old. The only reason we'd ever hear about them is because the NSA has something better in operation. A lot of the UFO sightings and photographs from the early 1970s turned out later to be Nighthawk aircraft which didn't become publicly known until 1981. There's a famous case where there were sightings by members of law enforcement, the military, and even civilian radar that turned out to be stealth aircraft a decade before we knew about them.

There's good reason they're not allowed in court and better reason why they shouldn't be allowed in any employment situation.

      If there was a really effective "lie detector", and it could be used without having to be physically invasive, I wouldn't be surprised if it would be kept secret because what would happen, say, if media outlets got hold of them? Imagine if media outlets could check lies told by each other. And we've already seen that technology that becomes available often soon becomes available to everyone.

      And that makes it involuntary how, exactly? The entire application for the job is voluntary.

      For example, a police officer's supervisors generally have a right to question the officer about what happened in the course of his duties. But there were cases where police officers were accused of abuse. They were questioned by their supervisors, and their responses were used to convict them of crimes. They appealed, and their convictions were reversed, because, the courts said, they were coerced into answering the questions as a condition of keeping their job, and the answers were therefore involuntary (for purposes of the Fifth Amendment). Now (at least in New York and New Jersey), supervisors don't question officers any more after possible police abuse, because, they say, the answers aren't voluntary, can't be used against them, and their answers would contaminate the investigation and make it more difficult to convict them.

      As has already been noted, for interrogations, polys are used to allow one man to do a two man routine (good cop/bad cop). Polys are used by the NSA, CIA, etc., for hiring as a security blanket. They have a difficult problem (intractable, really)*: they need to weed out the "bad apples" to prevent espionage and the like. They do background checks, long questionnaires, etc. But while mildly effectively, none of that stops the occasional problem. Enter the poly. This is reserved for things like the CI Scope or Life styles questions. It may even be required to get a TS/SCI (not normally, but unusual circumstances can cause this where an extra comfy security blanket is required).

      It is this security blanket function that causes the NSA, CIA, etc., to turn a blind eye to the truth about polys (that they don't work). It is a magic charm for them, and after the incantation they can *believe* that the person who passed is truly good and honest and won't sell out his country. It is a matter of faith, not knowledge.

      Reality is a lot sadder. One of the worst intelligence breaches suffered was when the head of CIA counterintelligence decided to make some extra money by selling the names of Russian's we'd turned to the KGB. He'd sell a list, there'd be a purge and the CIA would wonder why. Well, it didn't take a genius to figure out the Russians had someone inside the CIA with access to the information. So they started a hunt for the mole. Unfortunately, the head of CIA counterintelligence was part of the group trying to identify the mole. Yes, they did eventually catch him. His name: Aldrich Ames. This is also a classic example of who watches the watchmen.

      Have polys stopped espionage? The evidence doesn't indicate that it has, but the government has their security blanket.

      When was this? If this happened after 1988, it was very likely illegal under the The Employee Polygraph Protection Act of 1988.

      Commercial businesses may not polygraph their employees on a generalized suspicion that someone did something. They may polygraph an employee if they have a "reasonable" suspicion that that employee did certain illegal things, like theft or embezzlement. Even in those situations, employers must follow specific, strict rules - the employee must be given the opportunity to review all questions in advance, consult with an attorney, and not must not be asked questions about things like his political beliefs, associations with unions, etc. Most importantly, the results of the test may not be used as the sole basis for disciplining/firing an employee - there must be independent corroborating evidence.

      And that's just the federal law on polygraphs. Alabama, Florida, Idaho, Illinois, Louisiana, Maine, Maryland, Nebraska, New Jersey, New York, Pennsylvania, Tennessee, Utah, Vermont, Washington, and Wisconsin all have other, stricter laws regarding polygraph testing by private businesses.

At that point it's a guided interrogation with the polygrapher using indications from the machine to try and figure out if there's subterfuge going on. If the subject is able to provide reasonable explanation for the readings and what goes through their mind when queried then a good polygrapher will let it go. If they see enough of this kind of reading or they just get a hinky feeling they will make the subject come back for another reading until they feel like they have gotten the truth.

      • Becoming angry (any question that sounds accusatory could trigger this reaction)
      • Having anything trigger suppressed memories (perhaps of a previous interrogation, which the polygraph could remind you of, or perhaps something else, like questions about sexual activity inadvertently triggering suppressed memories of a sexual assult)
      • noticing partway through that the polygraph opertor is attractive
      • and several other things

      The result of this is that any attempt to mechanically interperate the lines on he page in any way other than "something is bothering the subject" is doomed to failure. If deception is really what you are concerned about, the only way the polygraph can help is to have the polygraph operator interpret it in exactly that way, and ask what is bothering the subject. If the subject can give a reasonable explantion, then the process proceeds, perhaps asking additional questions about what is bothering the subject if there are any security concerns related to that.

        If the subject cannot give any form of explanation (denies being bothered by anything) then there are three possibilities. One is that they are bothered, and thus by claiming they are not they are trying to deceive the operator. The second is that they they are not conscious of what is bothering them so they cannot provide any information. The final possibility is that nothing is bothering them, and the indicators are actually caused by something else like a medical condition, software glitch, etc.

      A deception expert might be able to determine which of those it is but since most polygraph operators have relatively little training in deception, they have little hope of distinguishing between those cases. Furthermore, since the polygraph only detects if something is bothering the subject, it only detects deception in people who are bothered by lying, either in general, or because they are afraid that the machine will magically detect their lie.

      Notice that I said nothing about yes or no questions. The machine can be used properly with other questions.

    In the subject matter of hiring for the NSA, it makes sense to the NSA to use the polygraph tests if the costs of losing out on a few hires who get false positives is less than the costs of not catching nefarious parties only administration of the polygraph test would have caught (or dissuaded from applying entirely). That may not be the best outcome for each person getting hired, but it's the best outcome for the NSA, and the NSA's goal isn't to employ people.

    In the medical context, you generally want the cost of the test plus the cost/impact of administering the test plus the cost of treating false positives to be less than the cost of not catching whatever you are testing for.

    If it costs $100 to administer the test, and the test has a 1% false positive rate and the cost of a false positive is $1,000, that's a good test to take if even 2% of people have what you are testing for but the cost of not catching it is $10,000.

      Let's throw this in: out of the 1 million people who might be infected, only 1,000 actually are. If your test says 10,000 people are infected, it's useless. OTOH, if 500,000 people are actually infected, then maybe an extra 10k aren't so bad.

      Every situation will be different, but the gist is that if you're going to use a detection technique for broad screening, then it needs to be very, very accurate.

      In the NSA's case, the number of people who have deliberately leaked information is very small compared to the number of job interviews they go through. I'd bet that more people have simply mishandled information (or will end up mishandling information) in the sort of accident that could happen to anyone.
