Preprint of a new paper examining the material conditions that give rise to internationally recognized scientists just came out. The authors argue that if we were actually recognizing and nurturing scientific talent, we'd expect the family income distribution of Nobel laureates to be roughly normal (i.e. most Nobel winners would come from families with incomes around the 50th percentile). Their results very much do not bear this out: the average Nobel winner grew up in a household in the about the 90th percentile of income no matter where they grew up, with disproportionately large numbers coming from the 95th percentile and up. This strongly suggests that academic achievement, especially at the highest levels, is not a meritocracy, but rather limited by the material conditions of birth.
I know, but the size of the effect is really staggering.
It's not just that you did not see your parents struggle. The academic world Is fiercely competitive, the positions are extremely precarious and badly paid until tenure.
It's no surprise that those that do not have to worry about their economic situation can take higher risks and survive more failures than those who do not.
