It is obvious that genetics matter. What isn't obvious is how, or how much. Ontogeny is context dependent at every scale of analysis. As such it is sensitive to precise manipulation in myriad ways, the vast majority of which are likely not yet known. We remain profoundly ignorant of what intelligence is, let alone what underlies it. It's likely that large population differences are the result of a synergistic interaction of genetics and culture, with each depending on the other. Ashkenazi Jews benefit from one such interaction, but there may well be many others yet to be discovered. I disagree that the social theorists as a whole are entirely ignorant of basic biology. I think they would argue that the cultural forces swamp genetic signals often enough to be worthy of criticism. There are no doubt theorists with views that are more extreme, but the appropriate response isn't to counterweight by going further in the other direction. Group membership cannot be destiny. If it is we're not free.
