I'm not claiming it, just repeating it, it's very well known in IQ testing. Ashkenazi Jews test more than a standard deviation above the mean.

anything that says that IQ tests don't work is just woke DEI "we don't like the results so we'll dismiss them". IQ testing is a very well trialed and tested field, it's one of the earliest uses of statistics in science.

So you do think Jews are smarter than non-Jews. I welcome your return to reality. It will be well deserved.
