"Since the early 20th century, raw scores on IQ tests have increased in most parts of the world. When a new version of an IQ test is normed, the standard scoring is set so performance at the population median results in a score of IQ 100. The phenomenon of rising raw score performance means if test-takers are scored by a constant standard scoring rule, IQ test scores have been rising at an average rate of around three IQ points per decade."
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

You assume too much about half of the human population.
