I said, "Actually, he names a couple of scientists, including one who specifically argued his corner."
Haier is the one who specifically argued his corner. But he also argues that David Reich and, yes, even James Flynn are consistent with the idea that there may be genetic causes for differences in IQ across groups. In fact, you even quote him saying that.
My apologies - I should have been more clear. I was specifically talking about stereotype threat and testing for racial group differences on "raven's progressive matrices".
Hmmm...that's rather specific. Anyway, the Radiolab episode I was talking about is here:

No, there is not a need for "all" their peers to agree, and a scientific consensus is not a phrase that needs scare quotes around it.
I put quotes around it because "consensus" is the word you used, but not one that you have demonstrated. Can you show that there is a consensus that it is "quackery". And by that, I mean not just something that may not be true, but some form of pseudoscientific fraud?
I'm aware enough of my own bias to know that I'm probably more biased than I think I am. It's not an unfruitful line of reasoning.
But it doesn't get us anywhere. Let's say someone believed Manchester City would win their Champions League match against Liverpool because it seemed likely on form, and a Liverpool fan believed that Liverpool would win because of some blinkered, one-eyed fanaticism which also included rampaging racism, homophobic bigotry, anti-semitism and raging misogynistic reasons, and moreover because of an utterly irrational hatred of the colour sky blue that Manchester City happen to have as their football strips. One person is extremely biased and the other is not. It doesn't mean that Liverpool didn't win the match.
I mean, I know from my own biases that I would much prefer that the science was clear that race was a completely socially-dependent concept (in fact, my own position more or less), and that there could be no genetic reasons for saying that one group could be different in terms of intelligence than another. But that doesn't mean that those who self-identify one "race" or another cannot possibly have a different distribution of genetic predispositions in terms of intelligence, or that such differences may have different life outcomes.
I don't know, which is why I said "I doubt" instead of "I know".
Why? People who like to debate ideas often go up against people who disagree with them.
