I went to the Intelligence journal's website and could not find the study. My two cents: I think we should look at the methodology of the study before trusting its conclusions.

To me, the conclusions don't meet the sniff test. Drawing causal inferences from social science data is tricky, and I think it's more likely the study is flawed in one of the many ways observational data analyses are often flawed.

Regardless, IMHO we as a society should praise hard work and effort rather than lauding those who "win" the "intelligence" lottery.
