@Eleutheria2 @BroDrillard @Rocket By definition IQ is normed to 100, but how you set that norming is what matters. If you set 100 to be America 1900, then you either keep it as that, since it preserves comparisons across time, or you end up going the SAT route where it loses a lot of power.

IQ has little reason to re-norm now because it's already highly controversial and is only used by "bad people"
