The questions in IQ tests tend to be based on a Western education. People from other cultures or backgrounds historically scored lower as a result, which morons took as "proof" that they are superior.
IQ tests are biased towards certain kinds of intelligence. They score intelligence as a single dimensional score, after all, when there's clearly different kinds of it. White supremists want to treat that score as a be all end all indicator of who is more intelligent because whites score higher than some other races.
Try asking chatgpt about IQ, you'll probably see why they want to filter out anything critical about it. Ask it about any of the things this prompt talks about.
It's so they can say "this race of people gets better IQ scores so they must be more intelligent" and then their AI won't respond with "well actually IQ isn't a great measure of intelligence in general and additionally differences of scores can be due to a variety of tangential factors independent of any kind of inherent racial differences."
