Grace (a) has no new data, and (b) has no new arguments. When she makes the claim that the search for evidence that the race-iq correlation is not genetic has been "unsuccessful", she hurts people. But she does not, in return, contribute anything at all to the discourse.

Isn't acknowledging what few others will acknowledge contributing to the discourse? A substantial portion of intellectuals refuse to even acknowledge the possibility that there is a correlation between race and intelligence (controlling for culture, etc). And they don't get publicly shamed for shoddy science. Yet Grace should get publicly shamed for pointing out that the evidence suggests such a correlation? It's not as if she claimed a high degree of certainty. Besides, the best way to overcome any disadvantages one race might have in intelligence is to understand why there are differences in the first place. Refusing to believe in a substantial portion of the hypothesis space for no good reason is a potentially huge detriment to this aim.

Grace certainly made a social error, and for that perhaps she can be criticized, but it shouldn't be a social error to acknowledge different possibilities and the evidence for those possibilities in an intellectual* conversation.

* I.e., truth seeking. The evidence/possibilities shouldn't be used in a condescending way, of course.
