I suspected that I shouldn't have put that into my post or should have qualified it with a statement regarding how completely useless of a metric it is. My general point was that probably around half of the planet is humping a tree as we type at our computer and pontificate about the human potential and dignity, regardless of a useless score that slightly correlates with things.
IQ isn't useless. It does correlate with violence (rape and pillage?) and of course it's a powerful predictor of academic performance, future income, and even life expectancy.
As soon as it gets mentioned to make a point, it incites a completely orthogonal discussion about what it means, its validity, socioeconomic bias, racial bias, etc
