In practice these priors are roughly as informative as those for clothing choice and the environment of interaction for predicting behaviors.
That's what I meant by it being a social category. A social category with a visible marker! At least the Burakumin can hide in plain sight.
The other problem with the usual question "race and intelligence" (which usually seems to start at "black Americans and intelligence") is that our tool to measure intelligence is IQ tests. Although a 10-point IQ difference within one social group that e.g. correlates with lead in paint is something to worry about lots, it's ridiculously easy to get 15 points' difference between groups for really obviously social and cultural factors (e.g. Burakumin). So if you're measuring IQ between groups, a difference of 15 points or less may well be cultural. And then there's the Flynn effect, which could be culture or food.
The x axis is a genetic magical category, the y axis is incredibly shaky and people are way invested in the answers. What could possibly go wrong?
Didn't the eggheads say back in 1994 that it wasn't due to cultural bias?
"Intelligence tests are not culturally biased"
Wow its sounds dumber when I quote them.
Heck, what do I know? I can't be bothered to read more than one page on this stuff. Got my info from this flyer.
Please remember to have no heroes or villains, but this just looks plain bad to be honest. I'm lowering my estimation of the quality of Stephen J. Gould's work in this area.

Haha. Humans.
