The tests you're describing haven't been done in an unbiased way
Yes they have, and I'm not going to bother with your cherry picked inanities.
The gold standards for IQ testing have been Raven's Progressive Matricies, Stanford-Binet 5, Wechsler Adult Intelligence Scale 5, Woodcock Johnson III and a whole host of other IQ tests. They have been designed by progressive sociologists to bend over backwards to account for every possible bias and take extraordinary lengths to be culturally/linguistically normalized or be entirely nonverbal like RPM. There is no magic 'gotcha' bias that you can point to like you're some freshman in college who thinks he's outsmarted the professor. There's an entire field of psychometrics filled with accomplished scientists who have pored over IQ testing methodology to try to isolate and eliminate sources of bias.
And The Bell Curve accurately states the conclusions of modern psychometrics- that IQ results are stratified by race.
The Bell Curve doesn't make any conclusion about nature vs nurture and the causation, it doesn't declare genetics the root cause. You can look to more controversial scientists like Rushman for that speculation. The Bell Curve simply states the well evidenced fact that the stratification exists, and the testing repeatedly shows this and you'd have to cook up the most hilariously biased testing like 'street smarts' and 'personality' in order to offset that.
