Is IQ the issue or simply talent in that particular area? I think talent in Physics and Math might be counterbalanced by lack of talent in verbal skills which makes the entire IQ question irrelevant. Did not Feynman have an IQ of 126? The inventor of the transistor was thought by one of the original IQ testers to be extremely stupid. I forget the whole story. Watson {DNA} I think was 115.
I heard that the IQ test was slanted as to make girls and boys on par.
