> Their facial images were obtained from their profiles on Facebook or a popular dating website So, this seems to be doing profile picture recognition, not facial recognition. It's not like they're saying there are physical features in your face that give away your political affiliation - that is to say, putting two people's bodies under the same photographic conditions would probably not create this kind of signal. What this is probably training on is the cues for cultural values that we self-select in our most deliberately promoted images of ourselves. If you have a carefully-chosen profile picture, it probably includes signals of what's important to you, especially if you're using it to attract people with similar values.

  The paper says predicting based on sunglasses use is only 52% accurate, so probably not.

  still leaves the micro- and macro-expressions, small grooming cues (makeup, no makeup, eyebrows trimmed or not), hairline, head angle vs. camera, lighting etc. These are all things that humans very specifically deploy to define themselves and their grouping, and communicate with others. So I am guessing a whole universe of personal yes-no qualities, political and otherwise, are encoded there, quite intentionally.

    I'm sure you're right. But it makes no difference, because when the facial recognition is applied, I think the likelyhood that people will have the same "grooming cues" as they do in their profile pictures is pretty high. If I have short hair in my profile pic, I probably have short hair in my everyday life, in the moment that my face is recorded and processed, as well. Yes, I choose how my face looks myself. But that does not mean anything, as objectively it is the same, whether I intended to or not.
