Jewish IQ, Ethnocentrism, Dissident-Right Discourse Quality, and Ubersoy vs. Leather Apron Club

Clarifying why Ashkenazi IQ and ethnocentrism are trivial issues, and critiquing what the DR pays attention to (not enough exousiology)

Recently there was a discursive exchange involving two “dissident-right” (DR) Youtubers, Ubersoy and Leather Apron Club. It centered around Ashkenazi IQ and ethnocentrism. Leather Apron Club claimed that Ashkenazi Jews only have an average IQ of 103.

He misreads a Richard Lynn study, performs shoddy math on Israeli IQ, and states that claims of a genetic intelligence advantage for Ashkenazi Jews must be bunk. He then speculates that the numerous studies showing a high Ashkenazi Jew IQ are probably fraudulent, in that their data must have been whole-sale fabricated.

Ubersoy and a friend responded with a 50-minute Youtube video wherein the direct genetic evidence for superior Ashkenazi IQ is only discussed for 2 minutes about 40% into the video.

I think this is a massive flaw with the video, and I suspect that they brushed over the genetic evidence because it involves statistics somewhat more complicated that a scatterplot. In fact, they only interact with the evidence by showing a scatterplot! I say this not out of malice but because I remember when I was in high school and interested in IQ discourse — I did not understand GWAS and PGS on a level deeper than scatterplot. Other types of evidence were easier to follow.

Leather Apron Club can be trivially debunked with the genetic evidence. I will therefore explain where we get polygenic scores (PGS) from and why it shows that Ashkenazis have a significant genetic intelligence advantage.
