An additional question that is always on my mind when we are talking about IQ is this:<br>I am a Mathematician and in my mind a very important skill is to be able to change your mindset and not be stuck in your first thought or intuition. And this is a beatiful thing about a hard problem that you should be flexible and open not just a computing machine. This happens with time, effort and a structured thougth (plans and heuristics).<br>Now in my mind IQ is tested with small problems that see computing power and small level pattern recognision. But all important problem are not small and may require something like what I mentioned above, even attention and focus are more important. Is there a difference bettwenn those. Of course there is some corelation but I dont know I have seen many slow careful people make magic. Are there studies that try to see distinctions bettween small and large problems.
