They had a common book and they were a minority community in central Europe. They specifically bred amongst themselves according to their values, which (consciously or not) prioritized intelligence. Not that hard to understand.

Yes but they also bred for intelligence, the smartest one was the one they encourage to have more kids, not the richest one, although the smarter you are the more likelihood you will acquire more wealth, e.g the rotchshilds.

Genestealers.
A small mostly inbred community, who interbred with the upper class of the goyim, selecting for high IQ traits.

A collective propensity for higher-functioning autistic spectrum disorders, this accounts for the lower spatial intelligence. My grandmother was of Ashkenazi extraction and had traits of Asperger's syndrome, so does my mother; uncle and to a lesser extent my cousins, I myself am diagnosed with Asperger's syndrome or higher-functioning autism.

Any research made after 1945 using living Ashkenazis as the only sample is going to be EXTREMELY biased. Just saying.
