I'm confused about the generality being important .... why does my g-factor score matters, if I'm great at all things that are relevant to my life? Maybe I'm terrible at most other things, and my g factor would be low ... yet I excel at what I need.<br><br>(Personally, I do NOT excel at all I need by a long shot. I believe to be a very good programmer, but I'm bad at social stuff, and much of daily stuff, and am very depressed and if I was smart, I surely would have been able to solve my situation better, so despite what everyone told me since I was little, I think I'm on average quite stupid, despite having talent for some abstract reasoning, etc. - In fact, I know of N examples of brilliant mathematicians, who cannot maintain their homes or relationships... - So, it's hard for me to see some unified general inteligence level behind it all, and it just seems that different people are good at different things.)
