Those genetic diseases are caused by genes that are dominant for superior intelligence, but recessive for the diseases. Ashkenazi Jews picked them up because they had to become smart fast. They were not allowed to own land. They were not allowed to enter most trades. The only professions open to them were commerce and money lending. These require superior intelligence. Jews that could not learn the necessary skills either had no children, or left the faith.
LOL......that is the most idiotic pseudo scientific nonsense I have ever read. ..
And yet probably true, Sunni.
We find the same propensity toward higher average IQs in other cultures whose lives and histories are, for one reason or the other, very harsh.
Over generations of a culture dealing with harsh social darwinism (or natural darwinism in some rare cases) the edge that superior intelligence gives people manifests in the group as slightly superior traits, INCLUDING higher intelligence.
Jews are abvioslyu not the only people so cursed/blessed by history.
But they are the ONLY people that this board is soooooooooooooo obsessed with.
Pick almost ANY group of people who went throght a holocaust (and that's a lot of differents groups of human, FYI) and you find that their average intelligence is slightly higher than the mean.
Now what is our affluent (easy life) culture breeding into our people?
Not superior intelligence, but
probably superior defences against communicable diseases.
Weird, eh?
The worse a PEOPLE are treated* (in history over generations) the stronger that PEOPLE become (statistically speaking).
Racially speaking it's: NO PAIN NO GAIN.
