Interesting.
The data Jews cite showing Ashkenazi Jews have a much higher IQ were all taken from a very small, select group of Kindergarteners sheltered within wealthy Jewish communities.
What's not talked about is how much lower they scored on spatial IQ and morality testing, like the hypothetical testing given to determine if someone is a psychopath.
When larger pools of Jews are tested, from different income levels, Ashkenazi Jews as a whole plummet in IQ.
Jews use these IQ studies to excuse Jewish overrepresentation in positions of power and wealth.
