I would have liked more pushing and direction as a child. I was fascinated by history and my father had done a reasonable amount of history at university level - I would have liked him to sit down and teach me stuff once a week. I was not able to do more than read myself.

I think IQ is nature but performance can be nurture and just because your IQ is x doesn't mean you can't perform a SD or so higher with work. We have to remember too that for every successful Chinese immigrant you see there are a VERY large number in China who may have been less successful (in a capatilist sort of way). And different populations can have different IQ distributions.
