Frankfooter, you are so tedious the way you drone on and on. Any person who is more than a casual observer of human nature should realize there are differences in intelligence among various ethnic groups.
Consider this from
https://en.wikipedia.org/wiki/List_of_Jewish_Nobel_laureates
"As of 2017, Nobel Prizes have been awarded to 892 individuals, of whom 201 or 22.5% were Jews, although the total Jewish population comprises less than 0.2% of the world's population. This means the percentage of Jewish Nobel laureates is at least 112.5 times or 11250% above average."
How does culture/environment explain this? These people came from all sorts of different backgrounds: recent Americans; Europeans who experienced severe antisemitism, or had to flee Nazi Germany; a few were actual Holocaust survivors.
Most impressive is the number of laureates for physics. To even understand, let alone glean new insights into things like relativity, quantum physics, sub-atomic particles takes formidable brain power.
