It's really not important. From my understanding, an IQ test is more about how fast your cognition is than it is about how accurate your conclusions are. You can have a high IQ and all it means that you're stupid, but faster. (and also maybe good at mathematics)
Also there's the fact that these IQ tests ignore specialized forms of intelligence. I have an average IQ, and while I might not be on some crazy genius level, I'd hazard a guess that most of the "high IQ" folk couldn't write a sorting algorithm or a shader if their life depended on it.
