The data on IQ is pretty solid. It's a massive predictor of success. I think Dr. Peterson (a clinical psychologist, and lecture of psychology at a top university) says it better than anyone. "If you don't believe in IQ then you may as well throw out all of psychology and the reason for that is that the psychologists who first of all developed intelligence testing were among the early psychologists who substantiated the statistical techniques that all psychologists use to verify and test all of their hypothesis."
Also, you can't increase your IQ very much by cramming "IQ test revision", (I believe it's only a third of a standard deviation, five points, you can increase, at the maximum.)
IQ is pretty much as established as evolution at this point. It correlates with the likelihood of going to prison, it correlates with the likelihood of further education, it even goes so far as to correlate between the different levels of further educations and then it goes on to correlate with various form of life success, such as financial success, and high powered jobs. The evidence in favour of it being a meaningful statistic is overwhelming.
