Race-IQ stuff as you call it is still a debated issue. The recent blowback over Nathan Cofnas’s work [1], for example, show there’s a culture where anyone not in line with the view there’s no connection is a target for cancellation. I don’t agree with the science from my layman reading of it, but I have much bigger issues with this attempt at silencing people by associating them with white supremacy.
