If inbreeding lowers IQ then why are Jews and Anglos so smart?

Jews were not that intelligent before breeding with german women. And the anglos have saxon/roman(brittania)/scottish blood.

oh forgot that the norse also migrated to britain.

That has nothing to do with inbreeding. Jews and beady Anglos were supposed to be dumb because of how inbred they are.

It's not inbreeding if only third cousin.
Outbreeding has negative effects also
The optimal distance for a mate is third cousin. All that keepin it in the family shit back in the day wasn't totally out of place.
