It's on its way.

Kirkegaard et al and probably others

What is your view on Piffer’s December 2018 paper, which looks at polygenic scores and ethnicity?

Piffer refuses to to deal properly with issues with his approach (poor control for spatial autocorrelation, subtle confounding in the ancestry of trained PGS). He's not very active these days.

It's pretty decent but just the same old methods. Poor SAC method. You can get more datasets if you look around.

Others can comment on the genetics (and they have) but are there no other sources you might use to observe the SES of WI Jews between 1957 and 1975, instead of assuming income of WI Jews in 2017 (when matched to other states) is representative? That’s a leap.

You need state level measure of jewish ses at that time. One could data mine old censuses/wills maybe.

I’m not seeing the online supplement - it seems like your tests were of the 53 Jews in the sample repeatedly against samples of 53 of the other religious denominations, is that correct?

@nntaleb tell me why this is wrong. I’d bet the authors don’t even deadlift.

Excuse the lay question, but is the 'Jewish Phenotypic Advantage in Educational Attainment' just a thing that is accepted? That it's phenotypical I mean? I thought the post Bell-Curve consensus was that there are differences in attainment but we don't know why. Is this settled?

That's what phenotypic means. I don't understand the question.

My mistake. So none of this speaks in any way to the question of if or how genotype and environment interact to bring about the attainment difference, or whether both genotype and environment are active, is that right?

GxE is unlikely for anything important, I wouldn't worry about it. This study shows that polygenic scores seem to mediate the IQ advantage of Ashkenazi vs. Gentiles to some degree. This is of course a simple prediction from genetic model of Ashkenazi intelligence.
