There is some correlation between success and IQ, but it's absolutely not a given. If you look at statistics you will see things like 'Average IQ of University Professor is 125 were as average IQ of factory worker is 85'. That sounds cool and all until you realize that the number of people that work at a university as professors is in the dozens were as the number of people that work at a factory is in the hundreds... and that average IQ spread of factory workers is 70 to 140 and the spread of professors is 110 to 140. These things operate on bell curves. Which means that there are a lot more high IQ people working at the factory then there are working at the university. Which means if you want to figure out what people are more likely to succeed in life then you should just ignore IQ and concentrate on what they have already managed to achieve.
