high intelligence is familial, heritable, and caused by the same genetic and environmental factors responsible for the normal distribution of intelligence.
so what is true of the demographics of the 125+ IQ population is true of the 145+ IQ population, only more so.

Yes, the links between parent IQ and child IQ are well established. Charles Murray is attempting to link IQ to financial outcomes. Those are not the same things

An IQ of 125 occurs one in every 17 people, so we're talking about the smart kid in a very small classroom. At the 99th percentile (IQ 135), we're down to 1 in 70... the smart kid in their grade level in a moderate-sized elementary school. If I'm doing my back-of-the-envelope math correctly, a group exclusively composed of individuals with IQ 125 or higher will only have 24% of its members in the 99th percentile... reducing them to statistical noise in Murray's data set.

135 isn't even DYS.
