There is a myth that above 120 IQ, returns are limited. I used to think that above 140 IQ returns were limited. Driven largely by the fact that cognitive and social disabilities seem to creep in rather rapidly above the 140s. But the data is looking pretty good now, that if you filter out the disabilities, there really isn’t a point of diminishing returns. What we seem to see is that emotional incentives for personal well being gate performance in very high ranges. So there seems to be over representation of achievement in the 150-160 range compared to the higher ranges. Probably because social bonding with peers is still numerically possible.

The problem for those of us at the extremes is finding a peer group within our own culture and value system. Otherwise social frustrations consume too much of our time and effort. This is one of the best reasons for the perpetuation of academic families. You feel ‘normal’ in those families above 150 because you’re in a peer social circle.
