Quite aside from my gut reaction, I discovered that there is no knockout killer blow for those who advance this argument. The science is not there and the claims are being made by social scientists, not geneticists. The issue of why black boys, in particular, underperform, is still there, but it cannot be answered through genetics. IQ is a measure of nurture more than nature and, as one sociology professor told me, I can better tell from your IQ scores whether your mum drives a Volvo than whether you are naturally gifted at maths.

People will, doubtless, ask why we are giving airtime to this subject, whatever our conclusions. But the topic is already out there and it needs to be tackled head on, on its own terms.
