He, of course, knows very well what the consequences for his career and social life would be were he to admit the unspeakable.
What you & Anatoly_Vorobey have quoted is talking about heritable IQ differences between individuals (“who do not have significant developmental disorders”). Is it possible you’re conflating that with talking about heritable IQ differences between races or sexes?
That you use the word “unspeakable” suggests you are, as does the fact that your twocases of scientists suffering career consequences (Gottfredson & Cattell) are cases where they suggested genetic racial differences as well as genetic individual differences. (In fact, if I remember rightly, both went further and inferred likely policy implications of genetic racial differences.)

That’s a good point, I think the two issues got a bit conflated in the discussion here.
However I can’t but see it as a reinforcement of my scepticism. My impression is that the partial heritability of IQ in individuals is well established. At most you can talk about doubting the evidence or not believing it or something like that. Shalizi says he “has no evidence” which is not credible at all.

Yes, I think it supports your dim view of what Shalizi wrote. I also think it detracts from your implication that he’s simply evading saying the “unspeakable”, since heritable IQ differences between individuals are a much less contentious topic than heritable racial (or sexual) IQ differences.
