Sullivan needs to let go of
Trigg race and IQ before it starts to embarrass him.
Yes, “race” is a social construct when we define it as “white”, “black,” “Asian” or, even more ludicrously, “Hispanic.” But why then does the overwhelming data show IQ as varying in statistically significant amounts between these completely arbitrary racially constructed populations? Is the testing rigged? If the categories are arbitrary, then the IQs should be randomly distributed. But they aren’t, even controlling for education, income, etc.
These concepts of ‘race’ are indeed social constructs. Sub-Saharan Africa has more genetic diversity than the rest of the world combined. ‘Hispanics’ can come from a lot of different places. If IQ tracks very well with a social construct and poorly with genetics, the default hypothesis ought to be that the collective IQ disparity is also a social construct. Sticking with a more complicated hypothesis makes you look less like the rational person in the room and more like a retrograde Tory clinging to the racialist baggage of the British Empire.
