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.



so… ones ability to interpret, quickly react, apply knowledge, and intelligence is not the best? sound like a fairly good marker to me.
The point is that you get better at it with practice. IQ tests claim to measure objective “intelligence” as trait that is independent of education, advantage, or other factors. But if a large portion of the test involves exercises that can be improved with practice, IQ cannot be an objective measure.
so its good if you don’t practice then?
