An Eye-Scanning Lie Detector Is Forging a Dystopian Future (wired.com) 113

An anonymous reader shares a report: Sitting in front of a Converus EyeDetect station, it's impossible not to think of Blade Runner. In the 1982 sci-fi classic, Harrison Ford's rumpled detective identifies artificial humans using a steam-punk Voight-Kampff device that watches their eyes while they answer surreal questions. EyeDetect's questions are less philosophical, and the penalty for failure is less fatal (Ford's character would whip out a gun and shoot). But the basic idea is the same: By capturing imperceptible changes in a participant's eyes -- measuring things like pupil dilation and reaction time -- the device aims to sort deceptive humanoids from genuine ones.

It claims to be, in short, a next-generation lie detector. Polygraph tests are a $2 billion industry in the US and, despite their inaccuracy, are widely used to screen candidates for government jobs. Released in 2014 by Converus, a Mark Cuban-funded startup, EyeDetect is pitched by its makers as a faster, cheaper, and more accurate alternative to the notoriously unreliable polygraph. By many measures, EyeDetect appears to be the future of lie detection -- and it's already being used by local and federal agencies to screen job applicants.

  • There is no correlation at all between externally measured biometrics and honesty. Lie "detectors" always have been, are today, and will always be snake oil. If you want to detect lies, there are probably just two ways to do it. One of those could be an fMRI, assuming we have a complete and unimpeachable understanding of the areas of the brain that control honesty. The other could be drugs.

    Perhaps a third could be physical coercion, but nobody wants to talk about torture anymore despite its history of effic

        Have you heard of any scientific study that correlates dilation of the pupil with lying? I haven't.

        • It would be very difficult to do a valid study. There is a lot of difference between lying about a circle or cross on hidden playing card, and lying about whether you gave the Russians your password, which is again different from whether you cheated on your wife.

          In many case truth vs lie may not even be all that well defined.

          For those and many other reasons, until I see refereed journal studies, I have 0 confidence in any "lie detector".

      Lie "detectors" always have been, are today, and will always be snake oil.

      Not true. They work and they are useful... if the subject being interrogated believes they work.

      It's almost like the placebo effect, except that placebo effectiveness is around 20 percent, whereas lie detector effectiveness is over 50 percent (and sometimes approaches 80 percent). Scott Adams (creator of Dilbert comics) explained this on his blog. He is a trained hypnotist and studies mental persuasion.

      Yes you can easily beat any polygraph if you receive training. But how many people in the general population actually get such training? And btw it's not enough to hear or read about how polygraphs don't work, you actually have to have some first-hand experience on how they operate... you need to see for yourself that you can manipulate the readings by doing various things (thinking different thoughts, feeling discomfort and pain by deliberately doing things like stepping on a nail hidden in your shoe, etc)

      Case in point: when you join a spy agency, they don't just tell you that polygraphs aren't scientific and they don't work, so don't worry about it. They give you actual live training on how to beat it. Because just tellling you about it isn't enough.

        That’s nonsense. There are multiple interviews with former FBI agents saying that you cannot effectively detect if someone is lying or not, whether it is through polygraph or some other meme approach, see Joe Navarro’s recent book on body language. What you can determine is if someone is nervous about the question being asked. That’s it, not more not less. Very often that is enough to at least tip you off that something may be going on, but it may also be that the individual just has some

      No, the dystopian part of it is pretending you can detect lies by monitoring the body.
      • Exactly, if you can 'prove' someone is lying with my black box of pseudoscience in a court of law then that gives you a lot of leverage.
        • Or, as in this case, even when you can't do that, it might still be used by the government in some other way that gives them leverage; like using it as a personality detector to choose which sort of people the government hires, when doing so honestly wouldn't be allowed.

          In that sense, it does detect lies; find a place where the machine is in use, and you've found a place where people are lying about what the machine does! 100% success rate AFAICT!

    • This is hucksterism, plain and simple. The polygraph test was not created to be used as a lie detector, and it has never been reliable in that application. This eye-scanner device appears to be little more than another round of bullshit: "Converus believes that emotional arousal manifests itself in telltale eye motions and behaviors when a person lies." Human beings are incredibly complex systems. Claiming the ability to detect what is in the mind of another human being based on some external cue, no ma

    • If everyone is honest, then there's no problem with a perfect lie detector.

      The problem with a perfect lie detector arises when it's only ever used on certain people. The people in power will never subject themselves to it, while gleefully using it on the people they rule over to assure obedience. That's how it becomes dystopian. It's fine in an already-free society. But it becomes a tool for those in power to prevent a non-free society from becoming free. And since no society is really ever completely

    Look, it's not hard to fool any biometric methods for detecting lies. They all are just measuring how you react to lying. If you believe (even incorrectly) that the lie is not a lie, or not important, they fail to detect it.

    They're looking for response. Kind of like the reverse of the Blade Runner detection, which looked for abnormal non-reaction to things that create reactions, and reaction to theings that don't create reactions.

    This will only catch people who want to get high, and poor people. Wealthy people will be coached in how to avoid detection.

      You can beat a polygraph by clenching your sphincter when answering questions, it causes a slight skin flush and rise in blood pleasure which is how the polygraph measures "lies", but they have to establish a baseline so if you do it every single time you answer a question the detection system can't see deception.

      Polygraphs are pseudo-science bullshit, and it astounds me to this day that they are still given any weight at all. Europe realized they were pseudo-science and barred their use for any reason, private or public, at all because they DON'T WORK.And best case is they just point you in the wrong direction.

    • Also, if you experience physical revulsion at being interrogated for things they don't have any reason to suspect you of, (which is itself a type of lie!) then you'll fail the test too.

      So people who dislike lying but are lying anyways will be detected, as will people who are more honest than average! I personally suspect it is the latter group that they actually are trying to exclude, for similar reasons that they want to exclude the people bad at lying.

      This. It's been a while since I last watched the movie, but IIRC we only saw Deckard perform a single Voight-Kampf test - on Rachel, and he most definitely did NOT shoot her. There's also a relevant fan theory [reddit.com] that he may have done a verbal version of the test on Zhora (the woman with the snake) with his questions about holes, and while he did shoot her that was only after she attacked him and in doing so confirmed that she was the replicant he thought he was.

    From noted experts on lie detectors and their weaknesses: Yes, they are measuring your current emotional/visceral response. Pathological liars do very well on these as they are acting out their stories (true or not); as they experience the universe of the story, it becomes their reality and their bodies react accordingly.

    Okay, you aren't a pathological liar. Can you focus on images, at least? You want a positive emotional response? Focus your mind on sex while answering a question. You'll inhale, your pupils will dilate, skin thermal and electrical properties will change. For an opposite reaction, focus on maggots on an open wound on your arm.
