You’re shifting the goal posts from the first sentence to the second sentence. What I said was: “IQ is real and highly heritable.” Responding to that by asserting that IQ tests are “skewed” and culturally biased, as OP did, is up there with vaccine denialism.

If you want to make a more nuanced point about what you can use IQ to prove, sure, that’s up for debate. But that’s not what we were talking about.
