A study conducted in Germany found that men with higher IQs are less inclined to traditional values, but the lead author, psychologist and intelligence researcher Maximilian Krolo of Saarland University, said the researchers did not find these differences among women.
I think that extreme upper and lower bounds do say something, but few point differences are entirely worthless. Scoring a 70 is rather significant, and 160 probably is too, but 100 vs 90 vs 110? Meaningless.
