Huh? He scored 566 on verbal and 640 on math for a total of 1206 points -- around 140 points below his Yale classmates. I'm not sure how this implies an IQ of over 130, unless you believe that Yale is attended by pure geniuses (hint: it isn't).
Furthermore, both SAT and IQ scores are highly correlated with the quality of education one receives. They don't measure innate intelligence.
But if we still care about IQ, then a 2006 study of presidential IQs estimated Bush's IQ to be around 125, the lowest in any president over the past 50 years, and higher than only three other presidents (Grant, Monroe and Harding). You can read about it if you want [1].
The better the quality of your education, the greater the influence of genetics on your IQ score. At least, that was my understanding of the WP article, which says poor environment means poor heritability.
Yes that is the general consensus, but there is quite a bit of argument about if it is true. The problem as in almost all these studies in the selection of the participants.
