Have you read https://traditionsofconflict.substack.com/p/the-intelligence-of-african-hunters (the title "The Intelligence of African Hunters, and the Ignorance of Popular Hereditarians" states the thesis). On Twitter the author has even quoted Galton on how clever the Bushmen are! You're also familiar with the conundrum of GSCEs in Britain (minimal black-white gap) https://georgefrancis.substack.com/p/solving-the-gcse-mystery . If the GSCEs were an accurate measure of IQ gaps in Britain, wouldn't African immigrants have to be mathematically impossibly unrepresentative of their home populations if African mean IQ was really 70? Even if we throw the GSCEs out, the black white gap in Britain seems noticeably smaller than in the US. And of course African and Caribbean immigrants regularly outperform native blacks in the States. Have you written about any of this?

Charles Murray posted the data for his "Human Accomplishments" book. Here is the post with a link to the Excel spreadsheet that one can download.

The list is pretty comprehensive. And as you might guess, there are no important contributions from Sub-Saharan Africa. There are important contributions from Ancient Egypt. But the people in North Africa are more closely related to Europeans than to Southern Africans.
