You've been reduced to mashing together official-sounding terms into a ball of nonsense at this point, since he's not even claimed to have taken an official IQ test whose score is documented - at least I've never seen him claim that. That's not the set of claims we're talking about in this conversation, anyway.
You may want to reread the bit on pseudo-skepticism vs. true skepticism, you are deeply confused about how reality works I'm sorry to say
Addressing your edit here, I will just say that you are overreaching at this point.
You obviously understand quite well that when somebody is (already dubiously and fallaciously) claiming victory in various discussions, supposedly due to demonstrably superior intellect, that the lynchpins of such an argument require that the claims actually manage to hold up beyond the level of self-proclamation and personal arrogance.
I didn't say anything about a "book" on my end.
You've already lost that debate. It's not complicated - you don't know his IQ, you don't believe his claims are credible - it's an opinion. If you're still confused go read about skepticism.
Keep trying
