If academic lineages are due to an ability that teachers have to identify talent, this ability is extremely common and predicts achievement FAR better than IQ tests can. I am struck by the degree to which the financial world fails to identify talent with anything like similar reliability.

Also, the above theory is inconsistent with the extreme intellectual accomplishments of East Asians, and previously Jews, within European culture and failure of those same groups to produce similar intellectual accomplishments prior to such cultural admixture.
