The IQ-genetic-origin deniers (NY Times, etc) have finally gone shtum for
the last few years; but many ill-informed & wasteful Public Policies (E.g.
in the US, castigating inner-city schools and teachers for ‘poor’
performance, Obama proposals for teacher Merit pay, the remnants of
Univ.-admission affirmative action left by Sandra O’Connor, and Labour
proposals re Mathematics led by Vorderman) are still around.

"It is clear that intelligence is at least partly genetically
determined. This was supported by the discovery in 2001 that the
volume of the brain's grey matter, made up of "processor" cells, is
heritable and correlates with certain elements of IQ (Nature
Neuroscience, DOI: 10.1038/nn758). The amount of white matter, which
provides the connections between these processors, has since been
shown to be heritable too (Journal of Neuroscience, vol 26, p 10235).
Now it seems that the quality of these connections, which is governed
by the integrity of the protective myelin sheath that encases them, is
also largely genetic, and correlates with IQ”
