My IQ is 136. I can attest that it is not an indicator of anything. I am a lazy, average programmer. Whatever benefit I gain from having a higher IQ is offset by my inability to focus for more than a minute. I don't understand how people can study and lack many basic skills because I aways seemed to sneak by without them. I am a chronic procrastinator, only the fear of having to write a final in 24 hours made me study/cram by pulling all nighters. I have a CS degree and rarely went to class, having collected every letter grade A+ through F, and survived being on academic probation (my semester with four D's and an A+). Just one data-point and a counter-example as to why IQ is not a good measure of anything.
According to Gwern[1]: It is worth noting that studies of human genius frequently say that raw IQ and talent are not helpful past unexceptional levels like 130 IQ; what makes the difference is motivation and the "drive to mastery"
