Reviewing the association between IQ and success
Charles Murray presented data in a misleading way in his book The Bell Curve, causing commenters on HBD forums (who also tend to be libertarian) to be confused and to think that IQ is more important for success than it really is.
Low IQ predicts poverty and failure much more than high IQ predicts success. Most of the association between IQ and success is because of this factor.
High IQ predicts more education, and more prestigious education, and then it’s the quantity and prestige of one’s degrees which cause success.
High IQ predicts parents with more wealth and social capital, which they use to help their children’s careers.
High IQ increases the odds of winning the super-duper-success lottery and becoming the next Michael Dell or Bill Gates, but only a small fraction actually achieve that type of success despite their high IQs.
Generally, high IQ without good education and parents leads to no more success than a person with an IQ of 100.

This post is just a quick summary of things I’ve blogged about for the last 10 years. Because there was confusion by some commenters and readers.
