One in 50 of Us is Face Blind -- and Many Don't Even Realize (theguardian.com) 202

An anonymous reader shares a report: Ever found yourself confronted by someone who seems to knows you, but you have no idea who they are? You could be suffering from prosopagnosia, a condition that new research shows affects more people in the UK than autism, yet largely goes undetected. Also known as face blindness, the condition makes those who have it -- including Brad Pitt and the late neuroscientist Oliver Sacks -- unable to recognise other people, and sometimes even themselves, by their face alone. It is believed to affect as many as one in 50 Britons. Dr Sarah Bate, an associate professor of psychology at Bournemouth University, is developing face-training programs to help those with face blindness learn management tools. She says many people with the condition go undiagnosed. Its impact can be severe if undetected.

      There's also an iPhone X app in there somewhere. One that would allow someone with this condition to have the phone's back camera, if Face Id were to be implemented on it, look at a possibly-familiar face, and identify the person if found in Contacts.

        As a bearer of mild prosopagnosia, such an app would be useless to me.

        First of all, raising the camera to people before approaching them (or, as it more often the case, they approach you) is rude. I much rather tell people I have face blindness and that I'm sorry but they'll have to be specific.

        Even had that not been the case, the people I don't know are people who I rarely meet, which means they won't be in my app's database.

          My prosopagnosia is pretty severe (had a medical event in 1998, applies to everyone I've met after, none I met before) - and while I mostly do the same I still really long for the pretty AR glasses with cameras that will give me back the same capabilities that I had (and others have).

        The obvious retort here is that Brad wasn't the one doing the choosing.

        If you knew anything about women, you'd have guessed that the literature reports that women do far more of the choosing than men do.

            I have this all the time. An example: I ride the train to work, and there is a woman I buy coffee from several times a week. She greets me like we are old friends, and I have no idea who she is, other than the coffee lady. I thought maybe she was one of those overly friendly people, but I have observed that she is not like this with all customers.
            I have concluded that there are three possibilities:
            1. She knows me from somewhere.
            2. She has mistaken me for someone else.
            3. She is really, really into me.

          I don't have face-blindness but I figured the scenario is like the following.

          We all have a general image classifier running, it allows us to extract enough features to easily recognize a coconut from a mango and, if we focus on the problem, distinguish two mangos.

          But most people also have a dedicated facial image classifier, and it's really good at extracting features from faces (or seeing faces in random things like rocks on Mars). But for some people this classifier is either missing or doesn't work well,

          I have a similar problem. I don't generally have a problem recognizing people I actually know but I find it impossible to find someone based on a photo (for example first dates). I also have a very difficult time keeping track of which waitress is my waitress when I go out to a restaurant. I also have no problem recognizing that I've seen someone before but at the same time have a hard time remembering exactly who they are.

        • It's rather like everyone else has a dedicated co-processor that takes a set of facial features and returns a person, but mine is broken, or needs much more training.

          This co-processor may not be just 'broken', but any degrees of 'broken'. Some faces are innately more distinctive than others, so your recognizer may work for the most distinctive ten percent of faces. Conversely almost all observers will be fooled by identical twins, even if you happen to be married to one.

        • I have FB as well. My brain just doesn't remember faces by default unless I have repetitive exposure over a short period of time. If I meet you for 10 minutes, I'll likely not remember your face the next day. I've been aware of this since my college days when I realized I did not recognize a girl I had gone out on a date with just a few weeks earlier. I try my best to overcome by concentrating on faces. It helps but not always.

          Sometimes, I can remember a face but not associate it with the person, but I s

Use geeks can get amazing things done in a short time, as long as we're allowed to focus on it.

      Prosopagnosia is the inability to recognize faces. People can still see the face itself and the features, they just can't recognize who it belongs to.

    • I've always been curious to know how people who are face-blind find other people attractive? As depicted in biology texts, they basically perceive faces as gray nondescript blurs. Do they have any attraction to faces at all, or what takes the place of this? It certainly opens the interesting notion of a group of people who are foreclosed from being as facially superficial as most people are...

      It's not that you can't see faces, atleast not for me anyway (I have a reasonably mild form), it's more that you don't have a bit of you brain that automatically collates all the relative sizes and positions of features and links that to a human identity. You can still see faces, and features, and be attracted to them, it's just that link to a person isn't as easy.

      As far as I know the grey blur thing isn't true, certainly not for the 1 in 50 anyway. For much more severe, perhaps.

    • Perhaps you should read the summary or the article?
      Why would anyone who is face blind see a grey blur instead of a face?
      Why would he not see random things as grey blurs?

    • It isn't being blind, but unable to different people by just their face. They will still see an attractive face, or an ugly face. But they have a hard time matching it to a person. For many of these people they are other factors that help them cope, hence why many go diagnoses. Things like Skin Color, Hair Color, general shape of the head, racial features. Other body features, the sound of their voice, their mannerisms...

      • I have a mild version of this. I remember names, I remember faces but have trouble linking the two together.

        The odd thing is, I sometimes see lookalikes that others don't. Like Shrek and Tom Kerridge.

    • Um, no. As A/C said, it's got nothing to do with seeing a "pixelated" face, we (yup!) see faces perfectly fine. The problem comes down to being able to reliably all of a person's facial characteristics with a specific identity.

      Furthermore, as with most psychological quirks, it's a spectrum. If you're affected by it, it doesn't mean that you can simply never identify a face, in some more extreme cases maybe, but in others it just means that you take longer to be able to easily remember & associate all of

    • I think that description of being a grey blur is misleading. i'm certain that these people can pick out features on any given face. If you ask brad pitt to poke someone in the eye, i bet he could do it. They just are unable to build a map from a set of features to an individual. They are unable to build a hash from a set of facial proportions.

      think about this. upon first meeting identical twins, they often look, well... identical. after spending some time with them, you get to notice subtle differences
    • Attractiveness is a made of whole lot of attributes besides facial features (body type, skin tone, smell, voice, mannerism and hair - to name a few).

      Besides, a person who suffers from prosopagnosia cannot construct an identity from facial features, it doesn't mean she can't determine if a face she's looking at is attractive to her or not (she might forget it a second later, but that's a different issue).

    • It's not like that. I can tell you that Person X is very attractive; I just can't reliably recognize which attractive person that is. And it's dependent on a lot of things - often I recognize people I don't know well by their voice, rather than their face. Or, to take the example which made it crystal-clear to me: I was watching Sliding Doors with my wife. It's a movie in which parallel timelines play out, showing the differences in the lives the main character leads based on whether or not she just barely
    • I'd guess that "gray nondescript blurs" is inaccurate. It sounds more like prosopagnosia is when someone's "coprocessor" that quickly maps faces to memories of people doesn't work so well. It doesn't mean they can't see the face or the features on it, or even try and pattern-match normally as you would an apple or an orange.

      I wouldn't be surprised if this eventually gets filed as an autism spectrum disorder. To me this sounds like just another "people skill" that normal thinkers take for granted tha

    • I wouldn't characterize it as perceiving faces as nondescript blurs. You can see the face and it's features just fine when you're looking at it. But a few seconds after looking away you don't really remember it.

I have no problem comparing pictures of faces side by side and picking out matches. But if you showed me a pictur

      My case is mild, but I don't think gray nondescript blurs is the correct way to put it.

      The face is there, and if you ask me questions about someone I can answer them without a problem, so long as I am seeing them right now. Ask me to look at a picture, and then cover the picture and ask me questions, and I'm hopelessly lost. I can see the face just fine, but nothing from it registers in memory.

    I recognize voice, gait and stance very well. I also have great recollect for floorplans and topography. Hair changes frequently enough to not be super helpful for me.

    My 3rd grade art teacher gave the class a project to draw your own face and I broke down crying because I didn't understand how everyone else could start drawing from memory. The teacher gave me a mirror, but just looking away from the mirror was enough to forget what my face looked like. Luckily, this is also the teacher that eventually taught me to just draw the individual lines you see. I'm still a shit artist for anything not predominately geometric.

      I'm curious, is it just faces, or do you maybe have a limited mind's eye visual recall altogether? I just recently learned about something called aphantasia, the inability to picture things in the mind's eye. I'm not fully there, but I've got a pretty low visual recall or imagination, and that might tie in. Really interesting thing to look into, if you think it might be applicable.

    • I wonder if 1/50 is truly face blind or all fall into related conditions. I don't think I'm face blind, I can pick out my wife from pictures pretty well. For me, I quickly forget facial features of people I don't see every day and tend to see familiar faces a lot with an initial glance, but on looking closer I realize it is someone else. I suspect linking faces to familiar memories is fairly common for everyone.

    • I'm not fully prosopagnosic but recognizing faces isn't a strength. If someone is out of context I will have a hard time recognizing them (even people I know very well). What I can do is recognize people from their gaits much better - how they walk and move is more identifying to me than what their face looks like). I'd never be good at describing what someone looks like for a police sketch artist - they have eyes, a mouth, and a nose in the normal positions. That's about it.
      • I should add that I do well on face recognition tests of famous people. My main problem is in vivo situations when people are out of context to me.
    • This. Like you, I've gotten very good at recognizing people by non-facial features - voice, gait, stance, and the clothes they like to wear. This has resulted in some what to others are impressive displays of recognition.

  • Considering that most social networks and cloud based photo apps can identify who a person is based on a photo, I wonder if an app exists that can help these people by allowing them to discretely take a photo and then tell them it's best guess who the person is if they've tagged them before or if they've been publicly tagged before.
    • The problem is, any such app would geotag people it identifies. That would limit the places/poeple who would allow it to function. Certainly, GoogleGlass was banned from bars over this issue.
