The methodology is simply false. They're not testing for IQ. They're testing for Educational Attainment.

We live in a jew controlled school system, so thinking that using white GWAS as an unbiased estimator for jewish educational attainment is hilariously flawed.
Let whites control Education with zero jewish influence for the next 100 years, then run the same test and we will see an entirely different genetic group of people succeeding in Academia.

Modern day Academia selects for clown world genetics, ie. jewish aligned genetics, so it's no surprise that they score highly on this. It's flawed data science.

It's possible that ashkenazi jews are higher IQ but the data analysis is deeply flawed and very lacking.

Also Ubersoy, who he quotes is jewish, and the substack you quoted is likely jewish too looking at his name.

And yes, jews are overrepresented due to nepotism.

Let's remember that jews were unable to pass the tests to enter university so they had to cheat the test by knowing the answers in order to get a foothold in US universities. It took them a long time to penetrate the universities due to this, but somehow we are to believe they are magically super high IQ? I'm not buying it. It's oddly convenient.

On top of that, we have Christian groups, like the Anglicans, that score higher than everyone else.
