"I've asked many people these questions and their answers are invariable. "Of course it would." The cultural correlation is undeniable: we've been indoctrinated to believe that the higher the IQ, the more likely one is to succeed in life. Hence, we assume that the scientists that win Nobel Prizes, the businesspeople that go from rags to millions, the authors that write runaway bestsellers, register in the highest ranges of IQ simply because they're enjoying sweet successes. Well, a tremendous amount of research has been done into the scientific correlation between IQ and real-life success, and a very different picture has emerged. IQ and success are related...to a point. Sure, someone with an IQ of 150 (a "genius" by all normal standards) is going to do much better in life than someone with an IQ of 80 (nearly "mentally disabled"). Similarly, a person with an IQ of 130 ("near genius") has a significant upper hand in life when compared to a person with an IQ of 100 ("average"). But here's the catch: the relation between IQ and success follows the law of diminishing returns. That is, when you compare two people of relatively high IQs, you can no longer predict success by IQ alone. A scientist with an IQ of 130 is just as likely to rise to the top of his discipline as one with an IQ of 180. Dr. Liam Hudson, a British psychologist that headed up Cambridge's"
