Lie Detector Glasses Coming Soon 457

Zelphyr writes "The EE Times is reporting on a product soon to be released by an Israeli company that allows the wearer of special glasses to tell whether the person they are talking to is telling a lie. Not only that, they can tell you whether someone loves you! Apparently a PC version of the 'love detector' is in the works as well.

        (He's lying)

        And they need to do it without tipping that person off. A problem with suicide bombers is that rumbling them away from the intended target can just cause them to improvise. Security checkpoints are nice and busy, and so are buses and shopping streets. It doesn't tip the balance if someone just blows himself up somewhere else that's still packed with people.

      You know, I'm by nature an honest person, and for a long time I wondered why we had the whole "politeness" bit: why are the hints so subtle, and why is it that those who can't / chose not to read them are just supposed to be endured, and not told straight out, "You know, I don't really want to hang out with you tonight" or "That's really boring. If you want me to listen you you, you'll have to talk about something else" or "You know, I really don't think you have a chance, and I don't want to waste my time or yours."

      But in my life, there have been several instances where someone who initially bores me or totally annoys me eventually grows on me, so that we become friends -- something that wouldn't have happened if I'd been rude and just told them off; and I've been on the receiving end of that too. I had a good friend tell me that when he first met me, he thought I was just an arrogant American and had no interest in getting to know be better; eventually we became really good friends.

      So with the "love glasses": even if they're 96% accurate as far as what's going on in the person's head right now, they're not necessarily that useful for what's going to happen in the future. The person who just thinks you're a nice guy, or even doesn't really care for you now, may get to know you better and begin to like you; and the person who is initially attracted to you and thinks your cute may realize you're not really her type.

      So this may be useful if you're just looking for one-night-stands, but if you're looking for anything else, I'd say it's best to stick with the social cues. They developed for a reason.

          Sciam is a nice science enthusiast magazine. As is the nature of the publication, the article is light on details. The magazine a good tool to be introduced to new information, but I would prefer to read about some hard studies, such as in JAMA [slashdot.org]

          (They do have this to say [ama-assn.org])

          Something I feel compelled to point out, that is a common irritant in much I read (Yeah, I admit it. I try not to, but guilty of it too): You have a logical fallacy in your assertion that I'd say they're as objective as you get, unless of course you believe in some kind of "science-conspiracy".. (Check out Wikipedia logical fallacy [wikipedia.org]

          You make the assumption that one needs to believe in a "science conspiracy" in order to presume that the magazine is not "as objective as you get."
          Bollocks. I don't believe in science conspiracy, yet I don't know the credentials of a particular journalist, so I can't assume that that particular journalist is completely objective or knowledgeable enough to report fully and accurately.

          Having said that, I personally dislike polygraphing, I think it is intrusive, like a mental form of body cavity search.
          Unfortunately, we don't live in a nice world, and sometimes the polygraph is a tempting, and if it IS accurate, then a useful tool. A problem of polygraphing is potential abuse. I hear of abuse stories a good deal. How many are true, how many are fabricated? I don't know.

      Yeah, but the psychological power of being hooked up to a machine that can tell if you are lying is huge. Sure, the system can be beaten, and that has been proven. But most people don't know that, and furthermore don't know how to beat it. So they might be willing to divulge the truth more readily if they believe that if they lie they will be caught. That is why the term "lie detector" is much more ominous than "polygraph".

      Is there a way to programmatically tell if someone is lying? I think there are general "tells" that most people do when they lie, and a computer can be taught to recognize these. But I don't think it will generally be accurate enough to escape harsh (and well deserved) scrutiny from the scientific community.

      Do you seriously think your Windows box cares if you love it or not? If it did, it'd be treating you much better.

      Actually, that *is* a fairly interesting proposition. Even if it were terribly inaccurate at reading the subtleties of emotional responses, maybe it could be used by machines as a source of additional input. Really now, imagine a kiosk at a retail clothing chain which offers you selections on what you might want, and gauges from its love-o-meter readings how strongly you hate the silk-sheen mauve stretch-fabric tee shirts and love the traditional white polo. At an even more granular level, such a kiosk would be able to gather tiny bits of information on what shades of which colors, what fabrics in what cuts, and such that you prefer. And all that with less interaction than would have been required otherwise.

      If you think about it, this kind of technology, if moderately effective and economically manufacturable, could be applied to any expert-system-type application that guides users to recommendations. Just imagine: An interactive porn catalogue that requires NO hands to operate (now *both* hands can be free)! Okay, that isn't my ideal application of the technology, but it's worth consideration.

    Remember back in 96-97 there was a big rage in "lie detection software" which supposedly would analyze audio input of someone speaking and then match their voice stress level to either "True" or "False" indicators?

    It was crap. I think more than a few morning radio shows tried to use it on their callers with failure after failure. I tried a copy myself and found that not only was it horribly written, but even if you were able to get the subject to "train" it (by answering several questions that are known to be true) it gave inncorrect responses virtually half the time.

    Come to think of it, the software might have been made by an Israeli company too. Maybe the same one, I don't know. Can't remember the name but it was horrid.

    Do I think the FBI/CIA might have technology like this, to analyze voice stress or facial temperature and determine if you are lying? Sure, why not. But there's a reason why lie detection technology is not admissible in court. It just doesn't work. Too many experts can beat it and too many amateurs get nervous and give false positives.

      Amir Lieberman, the developer of the system, is also responsible for the previous rash [jpost.com] of questionable truth detector [csmonitor.com] software, which happens to be still available [pimall.com]. It did recommend training, and it was widely sold for its ability to work over the phone. It even has a sequal [ex-sense.com]. (warning, Not compatible with Opera. Probably not Mozilla.)

      Namesysco doesn't claim very high accuracy [nemesysco.com] for the Truster software. "The voice analyst achieved an overall accuracy rate of 78% for truthful subjects and 61% for deceptive subjects." In other words, only 10% more liars were caught than flipping a coin, while 22% of innocent subjects were considered lying.

      The American Polygraph Society does not have a much rosier view [polygraph.org] of the situation. They have concluded that Computerized Voice Stress Analysis, and specifically the Truster software, has only a "chance-level detection of deception,"

      And actually, the dead giveaway to the scam should be from the lion's mouth himself. "Our products were originally for law enforcement use ? we get all our technology from Nemesys-co ? but we need more development time [for that application]" In other words, "our products don't work and can't be sold unless you slap a 'for entertainment purposes only' label upon them. Our products are to 'entertain' airport security."

      Good catch.

Can they really take a bunch of single-syllable responses, from people with such diverse backgrounds as you would find at an international airport, and determine who's lying?

    The heart of Nemesysco's security-oriented technology is a signal-processing engine that is said to use more than 8,000 algorithms each time it analyzes an incoming voice waveform. ...
    The law enforcement version achieved about 70 percent accuracy in laboratory trials, according to V Entertainment, and better than 90 percent accuracy against real criminal subjects at a beta test site at the U.S. Air Force's Rome Laboratories.

    So ... more than 8000 algorithms. And it gets even better results in a field trial than it does in the laboratory. They didn't mention its secret, unbreakable encryption with the 10^6 bit key -- just slipped their mind, I suppose.

    And, of course, this technology is so super-duper that they won't sell it to the government, but will market it to gulli^H^H^H^H^H ordinary consumers.

    Apparently the market for lunar green cheese flavored with snake oil is thriving (see: P.T. Barnum's Law of Applied Economics).

    Polygraph tests, and probably these glasses, too, make far too many assumptions about certain physiological responses which occur when someone is not being truthful. Firstly, they assume that a raise in heart rate or pulse can only mean that the person is lying, which is simply untrue. Secondly, unlike polygraphs, there's no way for these glasses to perform a control on the person being examined (meaning that you measure what a person's "normal" physiological patterns are like). And even those controls performed are dubious, at best, because there are simply too many variables to consider. Even in basic psychology classes, they go into the problems with polygraphs in detail, and it's not hard to deconstruct the test's assumptions, even for first-year university students.

    Suppose you went up to a girl and asked her when the last time she gave a blow job was, and she answers you (hypothetically, she'd probably slap you in reality). You'd probably register a raise in blood pressure and heart rate. Are you to conclude that she lied to you? No, that's simply absurd. You asked her a personal question, out of the blue. Of course she'd be surprised. Furthermore, are you going to act normally and cooly when someone with glasses that can supposedly tell whether you're lying or not is asking you questions? Probably not. If you're an innocent man being polygraphed to see if you've committed a relatively serious crime, you're not exactly going to be acting normally, either.

    Polygraph results are inadmissible in court for a good reason. I have a very hard time buying their "96% accurate" figure.

    The only thing this device can measure is physiological arousal level, and it can't tell one kind of arousal from another. This is precisely the same problem with polygraph.

    Both require interpretation. That requires training. Both can be bamboozled by anyone who can control their physio responses. That requires training too; yoga is good, but biofeedback is very simple and nearly subconscious.

    Anyone can learn to fool them. And I am not about to place my personal safety in the hands of some previously underemployed and undereducated, and presently overworked and undertrained glorified rent-a-cop. I mean, my respect and sympathy to the hardworking TSA people at the airports, but they are not EVER going to receive adequate training to be able to correctly interperate physiological response measures in context. I would rather trust a Scientologist with their "clearing" device (a simple electrodermal activity meter) because at least they have experience in interperating their results in the context of a structured interview. A polygraph is not a structured interview, and some security guard spouting random accusations in the form of questions definitely is not.

    I sincerely hope this is just another bogus device that is being publicized as part of the general anti-terrorism psyops, to keep the bad guys guessing as to what can really be done. Let them spend a few million on more high tech Dunsels. But if they deploy these for regular use, everyone who had too much coffee that morning and just rushed in late from a traffic jam to the airport is going to be targeted.

    BTW, the sign on my office (room 9-151, VA Hospital, West Haven CT) says "Electrophysiology Lab". I know whereof I rant.

    Metafilter [metafilter.com] pointed me towards a really interesting model for managing deception: Recognition detection. The idea is, rather than find out if someone is lying or not, simply find out if they recognize an object or scene they could only recognize if they were guilty. A certain brainwave, coined the P300 Wave, is emitted within a certain number of milliseconds of seeing an item one recognizes. One study, done by a group called Brain Wave Science, was able to reliably (and perfectly) separate FBI agents from average civilians by showing pictures of items from FBI training courses and operations. Detailed information may be found here [brainwavescience.com].

    I, of course, make no claims as to the veracity or accuracy of this material. But this wave is not pure pseudoscience -- the NYT has an article showing how weak P300's correspond to weak signal recognition. [nytimes.com] And BWS isn't the only group looking into P300 and deception.

    There are other approaches -- blood flow and PET scans come to mind -- but this has the advantage of involving just a few electrodes.

    So -- we may yet see a lie detector functional in our lifetime. Of course, it won't always be trusted, for reasons similar to the legalistic need for occasional exceptions to the rule of unique suspect DNA identifiers. But it'll be there.
