Thermal Imaging Lie Detector In Development

beaverdownunder writes with this quote from the BBC: "A sophisticated new camera system can detect lies just by watching our faces as we talk, experts say. The computerized system uses a simple video camera, a high-resolution thermal imaging sensor and a suite of algorithms. ... It successfully discriminates between truth and lies in about two-thirds of cases, said lead researcher Professor Hassan Ugail from Bradford University. ... We give our emotions away in our eye movements, dilated pupils, biting or pressing together our lips, wrinkling our noses, breathing heavily, swallowing, blinking and facial asymmetry. And these are just the visible signs seen by the camera. Even swelling blood vessels around our eyes betray us, and the thermal sensor spots them too."

    All this does is change the rules a bit. All of the things they've listed are things which one could train to do or not do on cue. And even without training if it's only good 2/3 of the time that's not good enough to justify deployment.

    Sad, but true. They tried this with an early prototype in 2008. Within 5 minutes it was engulfed in flames and set back the research by nearly 2 years.

    Does that mean you might be found 2/3 guilty of a crime, or will they roll a die and send you to prison on 1-4 ?

    It will be illegal to use this on politicians.

    We already have a visual lie detecting algorithm for politicians: "Their mouth is moving."

    ... all you have to do is memorize and rehearse lies in advance and imagine them and recall them as if they were memories. People get caught in lies because it's cognitively demanding to make it up on the spot unprepared.

    From what I've read, you're supposed to randomly lie or tell the truth on the easy questions they ask at the start to gauge your response.

    If you don't believe this consider religious faith. Many people I'm sure believe those falsehoods genuinely because they are well ingrained in their imaginations.

    But all my religious beliefs are true; it's only other people's religions that are unfounded.

    Saying religion is not some bronze age fairytale and coexisting with the scientific knowledge of the 21st century is something I find deeply offensive.

    It is time we stopped treating fairytales with undeserved respect or reservation.

    From what I've read, you're supposed to randomly lie or tell the truth on the easy questions they ask at the start to gauge your response.

    From what I've read, you're supposed to shut the hell up and invoke your right to be silent if you're being questioned about things you have done.

    Lying to public officials, especially federal officers, is in and of itself a crime. Lying gives officials facts which they can cross-check. Lying is something that ordinary people are generally bad at, and interrogators know how to get a suspect to move outside their pre-rehearsed alibis.

    Staying silent is not a crime. Staying silent does not allay an official's suspiscion, but cannot be used to convict you of a crime. Staying silent is something that oridinary people are generally bad at, but it's a hell of a lot easier to practice.

    Identify yourself, produce whatever ID you normally carry, and decline to speak about anything else unless you have carefully thought out what you are about to say, know that it is does not tend to indicate that you've committed some sort of crime, and know that it is the truth.

    The rules are quite different if you are being questioned about someone else or what they have done. But that's another story.

    All really good salesmen temporarily believe whatever bullshit they are selling at the time. It's kind of like method acting.
