I mentioned before Cosma Shalizi’s excellent discussion of heritability; add to that now his summary of g. We’ve got a few pompous no-nothings lurking in the comments who are fond of declaiming that they know that they have proof that the brain works in such-and-such a way, and that we can blithely assert an average stupidity exists in broad swathes of humanity (said broad swathes typically sweep across very diverse groups, united only by the obvious ephemera of skin color), but they need to read and comprehend those articles in order to learn that their certainty of a heritable simplicity is a phantasm.
Reality says that race is a category error, and that IQ foolishly tries to pin complexity into a cramped and tiny corner, and that human minds are both diverse and similar … and the great gross simplifications of racists, scientific and otherwise, are lies to comfort fearful bigots.
Cosma has another post that summarizes the exasperation we should all feel.
