Interesting - What do they eat that improves their IQ?
Gregory Cochran has always been drawn to puzzles. This one had been gnawing at him for several years: Why are European Jews prone to so many deadly genetic diseases?
Tay-Sachs disease. Canavan disease. More than a dozen more.
It offended Cochran's sense of logic. Natural selection, the self-taught genetics buff knew, should flush dangerous DNA from the gene pool. Perhaps the mutations causing these diseases had some other, beneficial purpose. But what?
A number of genetic disorders occur more frequently in certain ethnic populations. In the Ashkenazi Jewish population (those of Eastern European descent), it has been estimated that one in four individuals is a carrier of one of several genetic conditions.

Do you think IQ is the all encompassing measure of intelligence?

If we promoted high IQ behavior to humans everywhere, globally, would we all become… enhanced? Better humans?
What exactly is high IQ behavior? Being successful? What is success?
Is it stupid of me to want to opt out?
“It has always seemed to be odd that we like to call the human brain the most complex known object in the Universe, yet many of us are still prepared to accept that we can measure brain function by doing a few so-called IQ tests,” Dr Highfield said. “For a century or more many people have thought that we can distinguish between people, or indeed populations, based on the idea of general intelligence which is often talked about in terms of a single number: IQ. We have shown here that’s just wrong."

The Ashkenazi are plagued by numerous genetic defects.

Ashkenazi genetic diseases
...The origins of Ashkenazi Jews remain highly controversial. Like Judaism, mitochondrial DNA is passed along the maternal line. Its variation in the Ashkenazim is highly distinctive, with four major and numerous minor founders. However, due to their rarity in the general population, these founders have been difficult to trace to a source. Here we show that all four major founders, ~40% of Ashkenazi mtDNA variation, have ancestry in prehistoric Europe, rather than the Near East or Caucasus. Furthermore, most of the remaining minor founders share a similar deep European ancestry. Thus the great majority of Ashkenazi maternal lineages were not brought from the Levant, as commonly supposed, nor recruited in the Caucasus, as sometimes suggested, but assimilated within Europe. These results point to a significant role for the conversion of women in the formation of Ashkenazi communities, and provide the foundation for a detailed reconstruction of Ashkenazi genealogical history...

why would you say they are inbred? if you dont mind me asking. is that the reason they have so many genetic disorders?
