Tangential to this post, racial dilution is making this sort of thing harder and harder to measure and particularly who it's applied to. I'm not sure the exact number but I think it was something like 2% of American Ashkenazim outmarried 100 years ago compared to around 50% today. So the Ashkenazim of today, are they the same Ashkenazim of 100 years ago? As a genetic group, one would have to say no. Today they have far greater diversity within the group that is given that label.

Not to mention how laughably diversified "white" already is. That label at times gets indiscriminately applied to Argentines, Danes, Anglos, Russians, Poles, Italians, etc, as long as they live in the United States. Who exactly will these labels even be referring to in 50 years and how much will the group members have in common?

Returning to the present day, of what use are these statistics really? Handy heuristics I suppose? But even then there's somewhat broad differentiation at the individual level, even amongst siblings. Though it's uncommon, it still necessitates evaluating individuals on a case by case not race by race basis.

polygenic scores for IQ being higher for jews / asians isn't strong evidence that higher jewish / asian IQ is genetic. those polygenic scores are developed by fitting a model to predict IQ from genetic data. but measured IQ is subject to all the biases you already mentioned, and obviously ethnicity is encoded in dna -- so information about ethnicity contaminates the predictor. it's been known for years developing proxies for ethnicity is part of the way PSs get signal from genetic data

honestly before reading this, without looking much into the matter, i had given some credence to the idea that asians are smarter than whites. but if this is the best argument you can come up with in favor of that idea, i'm ready to abandon it

for jews, sure, i'm willing to believe higher IQ is partly genetic
