In particular, two semantic tricks are used. First, the fact that current genetic markers aren't a good prediction for IQ heritability is used as an argument against it. The other likely explanation that our understanding of those markers is widely incomplete is not explored.

Unlike our understanding of IQ, the game of matching shapes where the loser gets a teen pregnancy. That's been fully explored.

Science: “our current understanding of genetics leads us to believe IQ is not heritable”.

This fucking guy: “IQ is heritable and you just haven’t proved it yet. Citation: I belong to a race with good genetics, unlike you”

Honestly, I'm really surprised to hear that IQ is not even a little bit heritable, given that IQ test performance correlates with level of education, which correlates with wealth, which is heritable.

True, wealth is not genetic, but heritability has an interesting definition which leads to some unintuitive cases of heritability abd non-heritability. For instance, wearing earrings is heritable while having ears is not.

That's because the HN poster I quoted, like many many MANY people, has conflated predicting iq based off of genes with heritabilty. I'd recommend reading the linked substack, the author's much more succient and knowledgeable than I am, and I wouldn't want to misrepresent his point
