Scoring better in IQ tests means understanding the problems better -- if you encounter similar problems, or problems which provoke the same areas of brain -- better IQ test score should correlate with better performance in the said problems. Whether this happens alot or not is another thing though. However, as the TFA implies, we can practice and better our brain, intelligence and mental skils, maybe that's exactly what happens when we "work hard". We become more intelligent, more skilled, our brains work more efficiently which, when added with the fact that we use that brain more by working hard, makes us more intelligent/mentally capable/whatever. Of course high IQ/mental capability/intelligence means nothing if it isn't put to use, so step first is to start doing stuff which matters and learning from it.
