But how do you know that it was genetics and not some other factor that has led people like that to be like that? Or maybe a combination of things?

- honzzz 13y agoThis is basically the old nature vs. nurture thing. So the answer is similar - twin studies etc. Based on what I know (which is not much - I do not claim to be an expert) I would say that there is undeniable evidence that IQ is in fact strongly affected by genetics.
- kgarten 13y agothe question is also how much you rely on IQ as a measure. I found regarding nature vs. nurture, both camps have some good arguments .. btw, I found the wikipedia article on the topic interesting: http://en.wikipedia.org/wiki/Heritability_of_IQ http://en.wikipedia.org/wiki/Heritability_of_IQ
