And considering results are "gay" or "not gay", isn't "50ish % accuracy" like saying predicting coin toss at 50% accuracy? I.e. Bullshit?

Yeah, but they claim 90-ish if they have multiple pictures

Not that this matters at all but 50% is higher than chance. It's not 50/50 if somebody is gay. Gay people aren't 50% of the population.

The data was balanced, so I think 57% is not much better than chance. That was using their "facial femininity" feature only.

If I were to pick out a flaw, it would be from doing 20-fold cv on a dataset of faces where total images outnumbers number of people.

Ah, I missed that they had equal numbers of "gay" and "not gay" people. Nice catch!

The flaw isn't in the dataset really either way, of course.

Hmm what do you mean? I don't think it will hold if they took a larger sample, across subcultures and races.

I think it's inherently unethical researcher that doesn't reflect reality but either way is flawed.
