Very sensible and extensive input, garbagecoder, thank you very much. I do think IQ itself is a lacking approximation of intelligence, but the larger problem is that the data is probably highly distorted. Also some with the same potential as another but who has never been challenged with these type of questions will perform worse. You will get better at IQ tests the more of them you do. It is questionable that your IQ increases. Granted, that problem is understood and addressed and you should not do the same test with the same type of questions again. But creating such tests is probably beyond the IQ of anyone. Also IQ tests are highly tuned to speed. While having unlimited time to solve questions doesn't say much about cognitive abilities, people with quicker judgments don't necessarily have better ones, often to the contrary. But the form of questions in IQ tests favors them disproportionately because every question itself all have a very limited scope and the measurement is about how many answers you get correct in a limited timeframe.
