If many millionaires have IQs around 100, & 58 y.o. back office clercs at Goldman Sachs or elsewhere an IQ of 155 (true example), clearly the measurement is less informative than claimed.

it is important to distinguish the macro from the micro point of view.

From the micro point of view, a talented individual has a greater a priori probability to reach a high level of success than a moderately gifted one.

On the other hand, from the macro point of view of the entire society, the probability to find moderately gifted individuals at the top levels of success is greater than that of finding there very talented ones, because moderately gifted people are much more numerous and, with the help of luck, have - globally - a statistical advantage to reach a great success, in spite of their lower individual a priori probability.
