You're wrong because your conclusion that Shalizi was either blind or lying rested on two premises: one, that heritability in racial IQ differences has been proven, and two, that for Shalizi to admit this fact would be uttering the "unspeakable" and would carry severe social and career-wise consequences. I wrote a detailed explanation about the way Shalizi challenges the first premise on statistical grounds, in the field where he's an expert (and in a way that's neither blind nor dishonest, albeit it could be wrong). I gave an example that illustrates that the second premise is wildly exaggerated, especially when applied to an academic such as Shalizi. That's why you are wrong.

Your response was to twist my words into a claim that you are "statistically incompetent", where in fact I emphasized that Shalizi's critique was on a deep technical level, and that I myself lacked knowledge to assess it. That is cheap emotional manipulation. You also cited a paper about Gottfredson that wasn't relevant to what I said. Given this unpromising situation, I'm sure you'll understand if I neglect to address further responses of that kind.

That's a locked-up paper printed in a journal operated by a political advocacy group.

Linda Gottfredson doesn't seem to have been "silenced", though. (But I have a libertarian, rather than a left/right partisan, view on that concept. Someone who takes grants from wealthy ideological supporters instead of from government institutions is not thereby silenced; on the contrary, that would seem pretty darn liberating.)
