Nice job at Oxford you’ve got there. Shame if anything were to… ‘appen to it…
Steve Sailer reports:
Ironically, the very low average IQs found in Africa can’t all be genetic in origin because the gap between Africans (mean IQ of 70 according to dozens of studies) and African-Americans (mean IQ of 85 according to hundreds of studies) is as large as the gap between African-Americans and white Americans (100). Yet, African-Americans are no more than 20% white by genealogy.
Richard Lynn himself has repeatedly pointed to poor nutrition as one cause of low average IQs in some poor countries. We know of two micronutrients–iodine and iron–that can lower your IQ when not in sufficient supply in your diet. That’s why in America salt is fortified with iodine and flour with iron. Extending these fortification programs to the Third World as a way to raise average IQ would probably give more bang for the buck than anything else.
