exactly how?
Or I should say, all humans are intelligent baring extreme circumstances (for example signs of genetic defect, potential inbreeding, or FAS may possibly be a sign of lower IQ it's not a certainty of it). Are we trying to say there is some correlation between 'high' IQ and outward appearance, because that is quite the statement, and one that really has no scientific basis that I know about.
It's honestly a pretty good case study of the limitations of the approach, because you can imagine all sorts of spurious correlations you might pick up from a photograph (limit case: subject is holding their framed mathematics doctoral degree) that could result in a classifier good enough to give you a betting edge, but good for little else. Broadly, you'd expect a trained photo classifier to pick up a bunch of SES signals.
