           | Questions:
           | 
           | 1. Should they do it (morally)? No
           | 
           | 2. Should they do it (proft motive)? No
           | 
           | 3. Can they do it (legally)? probably not.
           | 
           | 4. Can they do it (technologically)? Yes
           | 
           | 5. If they do it is it accurate? (See palm reading...)

         | Research in 2017 demonstrated a high level of accuracy in
         | determining whether or not the person whose face was in an
         | image was gay or not. 71% male, 81% female accuracy. When shown
         | 5 pictures, accuracy jumped more than 10% in either case.
         | 
         | This was with a relatively small neural network fine-tuned on a
         | relatively tiny dataset of 33k images of faces from a dating
         | profile site.
         | 
         | If I had a million dollars I'd gladly wager it that some
         | company with a deep dataset, like Google, could create a 99% or
         | better profiler that goes just off a video of someone's face
         | (not a single still image, but I'd bet that single image
         | profiler could beat 90%)
         | 
         | Transformers allow for a nearly arbitrary vector length for
         | feature space - if sexuality correlates at all to any of a
         | million different facial features, then neural networks will be
         | able to detect it. If you're doing a binary "straight or not"
         | test, without distinguishing between all the values of "not-
         | straight" , then you could use a very shallow, very wide
         | transformer architecture with a million features, and train it
         | on a consumer card, and get accuracy in the 90% range.
         | 
         | That initial study had technical flaws, not least of which was
         | the binary classification of gay and straight, and only using
         | white people. Technically, they used a base model, VGG-Face,
         | which had a 4096 feature model and 17 convolutional layers.
         | 
         | Human accuracy was rated about 50%, and was effectively a coin
         | toss with a slight accuracy advantage for women.
         | 
         | That's less powerful than something like nano-gpt. GPT-2 is
         | orders of magnitude more complex and has a much higher degree
         | of capability.
         | 
         | If you did this with nuance and skill and high technical savvy,
         | with a sophisticated model of sexual preferences (not the
         | 1950's notion of straight or not straight) you could get a very
         | accurate and deeply creepy piece of software.
         | 
         | This works for emotions, nonverbal communications,
         | truthfulness, etc. Biometrics can provide a terrifyingly deep
         | analysis of things you consider private and hidden but which
         | nonetheless present in unintended evidence available for
         | analysis.
         | 
         | If you had a few hundred of these types of analyzers - say, for
         | psychological factors, fitness, health issues, sexuality,
         | political preference, etc, etc, then you could not only get a
         | highly accurate snapshot of people through deanonymized bulk
         | surveillance data freely available on the market, you could
         | then create LLM models tuned specifically to the features and
         | preferences of each individual, and then use A/B testing on
         | your virtual populations to maximize engagement, force specific
         | reactions and behaviors in response to media (timing, pacing,
         | content, framing) , and so on, and so forth.
         | 
         | We're not nearly as inscrutable, private, or resilient as many
         | people think, and there's all sorts of data being misused
         | already. Maybe we should get that universal digital bill of
         | rights thing going before BlackRock or Honeywell or the DNC
         | decide to go all in on AI.
         | 
         | edit: To clarify, I'm not cheering this stuff on. No university
         | would allow the study, and most companies would open themselves
         | up to significant legal scrutiny if such a thing was ever used
         | and they got caught, but this is a weekend project for a quant
         | at a big firm - it'll cost them 20 hours and a case of red
         | bull, with all the AI infrastructure out there, and the time,
         | knowledge, effort, and cost to achieve things like this are
         | dropping fast.

             | The key conditional is a question that is answered in the
             | research already done, and it's "yes, sexuality correlates
             | to facial features." The more facial features you track,
             | the better the granularity, the more you'll be able to
             | correlate. How you smile, your gaze, your presentation, and
             | so forth all plays into facial features. These are going to
             | culturally tie into expression of sexuality, and you might
             | as well wear a sign for AI proclaiming your sexual
             | preferences. Changes in facial features from genetics,
             | hormonal levels in development, environmental factors, and
             | other peripheral effects will correlate with sexuality as
             | well, but not as strongly as the behavioral ones. The
             | inherent features are context against which the behavioral
             | features play.
             | 
             | It's not a physiogonomy trope or a statement that straight
             | people have different fundamental facial features, that
             | they grow differently - it's the macro and micro
             | expressions, the behaviors, the style and presentation
             | choices, and how those intentional active features play out
             | on the substrate of the individual's facial structure. A
             | small video snip is going to communicate a very large
             | amount of information. TikTok could do this - and then
             | create another model that inferred psychology and sexuality
             | based on watch patterns, and yet another model that
             | describes how different types interact and network, and yet
             | another model that describes how information propagates
             | through various networks, and so on, and so forth. Through
             | differential analysis and repeated refinement of various
             | models, you get to some very intrusive and scary places.
             | 
             | Anyway, /ramble. We need a digital bill of rights.

         | 
         | Not odd at all; it is to remove an obvious bias of recognizing
         | race.
         | 
         | I am supportive of the effort, but this seems to snipe at a

           | 
           | It is odd because that means they already had to separate the
           | dataset into various races, and we know how well that works.
           | What specific shade of skin are they picking for their
           | threshold. Are they measuring skull sizes to pick and choose?
           | Isn't that back to "phrenology" and eugenics. Then, how do
           | they define "men" and and "women"? Maybe someone is neither
           | but now they are stuck labeled in a category they do not want
           | to be in.

       | 
       | This of course correlates to earnings.

       | This does not, however, correlate to performance - earnings are a
