To answer this question, I calculated mean IQs for all self-described whites by the country they said their ancestors came from. Only people born in the US are included since immigrants are at a disadvantage on a vocabulary test (the measure of IQ used here). Here are the results:
Mean IQ
Africa 93.4
Mexico 90.0
Puerto Rico 93.2
Spain 97.2
American Indian 94.7
India 95.8
Other Spanish 95.9
American only 90.4
It looks like many of these people are racially mixed. They label themselves as white but often have some non-white ancestry. The mixed groups that do not have low mean IQs are self-described whites whose ancestors came from east Asian countries--Japan, China, or the Philippines.
UPDATE: The mean IQ for self-described whites whose ancestors are from east Asia is 99.8.
Hispanics who have colonial history in New Mexico (hundreds of thousands of people) refer to themselves as Spanish and so
ReplyDeleteI suspect they claim their ancestors are from Spain instead of Mexico. They never refer to themselves as Mexican and have a distain for their southern relatives despite DNA tests showing no difference in admixture rates between them and northern Mexicans.
I mean disdain. My IQ is now questionable.
