I see you cherry pick. Benet the inventor, realized it’s limitations. It was for ones peers not between ethnicities. Look up the meaning of PEERS.
It was devised by white Europeans, for white Europeans and certainly not for different cultures. Your ideas are silly. High intellect in Africa is around medical herbs, hunting and gathering. They can migrate and hunt over hundreds of square miles with little loss of life and never get lost.
The same for early Europeans who were master shipbuilders which used more math and physics. Your idea of intellect is ridiculous. It’s further proven delusional by the simple fact that IQ test results can easily be improved upon by practice, retakes and language and math skill development.
That completely disproves that a single test, given once is a number that determines aver intellect.
