How confident are you in your intuition on this matter? IQ does seem to be significantly correlated with a bunch of things that fall under the general umbrella of "getting ahead in life", like income and job performance:

I read the wikipedia article - thank you. However, I think we are speaking of different things! Maybe, maybe not. I speak of true happiness. I look at the people in my life that live "a good life" and the people I see succeeding are those with very little. I don't question, for one moment, that higher IQ leads to more opportunity, more money, more things. When I look at people who are happy, by the values upon which I place importance, the things that high IQ bring to the table aren't relevant. Maybe I have it all wrong, and I certainly don't have a statistical sampling to prove my point - just an observation!
