I would be very surprised if high intelligence was anything other than the extreme edge of a normal distribution of the human population. For it to be anything other than this it would require people of high intelligence to be a sub-population that did not breed with the rest of humanity.

Ashkenazi Jews would seem to be a well-studied sub-population that tends to possess above-average intelligence.

Even if it were true that Ashkenazi Jews as a group had above average intelligence, there just are not enough Ashkenazi Jews in the world to have a significant influence on the distribution of human intelligence.
