Law Enforcement Agencies Recruit Rare People Who are 'Super-Recognizers' of Faces (theguardian.com) 23

An anonymous reader shared this report on "Super-Recognizers" from a series of articles in the Guardian called "Meet the Superhumans." As a child, Yenny Seo often surprised her mother by pointing out a stranger in the grocery store, remarking it was the same person they passed on the street a few weeks earlier. Likewise, when they watched a movie together, Seo would often recognise "extras" who'd appeared fleetingly in other films... A cohort of just 1-2% of the population are "super-recognisers" — people who can memorise and recall unfamiliar faces, even after the briefest glimpse.

The underlying cause is still not entirely clear — it's a new field, with only around 20 scientific papers studying super-recognisers. However, it is suspected genetics plays a role because identical twins show similar performance, and it has been shown that cortical thickness — the amount of neurons — in the part of the brain that supports face recognition is a predictor of superior ability. Because it's such a rare phenomenon, in 2017 Dr. David White, now a lead investigator at the Face Research Lab at the University of New South Wales (UNSW) and his colleagues designed a publicly available online screening tool to try to unearth the world's best super-recognisers. Seo, then in her mid-twenties, gave it a go — and her score was so high, White invited her to come to Sydney for more testing.

With more than 100,000 people now tested, Seo still ranks in the top 50....

Over the past decade, security and law enforcement agencies around the world have started recruiting people with superior facial recognition capabilities. London's metropolitan police has a special team who examine CCTV footage from crime scenes — they were used in the investigation into the poisoning of a former Russian spy with the nerve agent Novichok in Salisbury — and several years ago Queensland police started identifying super-recognisers in its ranks. A proliferation of private agencies has also sprung up, offering the services of super-recognisers.

Seo has no interest....

    It looks like people can still be better than AI. Who would have thought that?
    • With a name like Seo, you could say she was born for it.

      No. People are good cover for AI.

      Officially, the output of the 20K cameras in between Gatwick a hotel in London and then between the hotel and Salisbury on the next day are not collated and not analysed using image recognition and tracking software.

      By claiming that you have used a super-duper genius to review a total of 40K days of footage you get plausible deniability that you are not collating the information of the aforementioned cameras and not analysing them using AI.

      research is already underway to see if this can be adapted to slashdot editors, so as to recognized stories they've seen before . . .

        Seriously though, if Slashdot was more searchable it would probably help drive more traffic here. At the moment it's very hard to find specific stories, and Google seems to have a hard time indexing the site. It's almost as if it was designed to be anti-SEO.

  • I must have overridden the facial recognition part of my brain with Brady Bunch trivia as a teen. For me most black people really do look alike. Same with asians. Same with us crackers. If I'm introduced to someone, then see them the next day, I often have to wonder "is that Dave?"

    They have been doing that for decades, even if YOU read it only yesterday.

  • I recognize many faces all the time. I know I've seen them somewhere - sometimes a long time ago, somewhere else. I just know it.

    In the case of movies, when the fleeting face is interesting enough to me, I'll look up the cast of the movie, find out who it was (not always possible if it's a very small role or a cameo) then look up other movies that actor was in, to figure out where I might have seen them before.

    But... Here's the clincher: I know I've seen a lot of people somewhere, but if it's not in a movie

    • I'm similar, but in my case I can see the resemblance between one actor and another. It's not that I mistake the two, it's just that I see the way one man's face is the same shape as the other's, or whatever. And when I comment about it, it's often hard to get somebody else to see what I mean, probably because they're looking for a more obvious resemblance than what I'm seeing.

      Yes, your parents always complain that you never say hello.

    The opposite of a "super-recognizer" is often someone with aphantasia [wikipedia.org]. This is the lack of the ability to create mental imagery. It tends to have a significant impact on the ability to recall faces until that face is extremely well known. Among other things.

      Actually the word you are thinking of is Prosopagnosia https://en.wikipedia.org/wiki/Prosopagnosia [wikipedia.org] This is sometimes called "face blindness" and is described as "a cognitive disorder of face perception in which the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision-making) remain intact." Aphantasia is a somewhat similar condition, but not the same
      • When my son was young, I used to have anxiety that I would have prosopagnosia and not be able to recognize his face when I went to pick him up at daycare. No idea where this anxiety came from, and it was never true. As soon as I saw him, I recognized him immediately. But then the next day I'd get the same weird anxiety again. Years later, the anxiety is long gone, but I still think back and wonder what was going on in my brain.

        No, actually what I am thinking of is aphantasia, just as I described. I know because I have aphantasia. It comes right along with not being able to recognize faces - because there is no memory or visualization of those faces whatsoever. When people without this condition think of a face, they can see it; I can't. Nothing. No visual recall whatsoever.

        Aphantasia is a somewhat similar condition, but not the same thing.

        I didn't say or imply it was the same thing as prosopagnosia. I said it was often someone wi

      Sort of. Aphantasia does not directly affect recognition, as you don't need recall for that. It does not affect recognition of familiar faces.

      But yes it does affect how I memorise a face. Without visual recall, how do you transfer an image from short-term to long term memory?
      I may have to meet a person a few times before I'll recognise them after not seeing for a while. Or I take photos and look at them.
      After witnessing a crime, I was completely unable to describe the suspect. (No visualisation.) But

  • Rare people who are "super-recognizers" recruit law enforcement agencies facepalms.

  • I took the online test. During the part where they show two images and you have to guess if they're the same person I would look at the first one and think "green eyes, mole on left cheek, right eyebrow is bushier than the other,..." and yet I still only scored 29%. That's worse than just tossing a coin.
  • Summary was apparently written by James T. Kirk.

  • I did the online test and scored 73% which puts me in the top 5% of all participants. (Smug f*cker that I am) However, there is no way I can explain how I recognise the faces. It was just a case of "Yep, I've seen that face before." I would be highly doubtful that I could give a researcher any clues as to a conscious process. Maybe they have to wire you up to an EEG and see what parts of the brain light up when doing the test.
