I have Pinker's book at hand as I type this. Pinker's detailed chapter on that issue is based on an article by Turkheimer, the author whose more recent paper I already cited to this thread as the first reply here. Pinker by no means has done anything at all to show that intelligence is "by and large an innate quality." The new and emerging rethinking of the interaction between genome and environment, which Turkheimer is doing a lot to pioneer, is driven by the data, not so much by any reaction from people in other disciplines.
