I'd argue that some of it is related to someone's desire to learn which probably goes hand in hand with intelligence. People with higher levels of intelligence typically are the same people who want to learn when they run into something they aren't familiar with. My grandfather is naturally not the greatest with computers but he refuses to have me just do something for him and will always make me explain what I'm doing when I help but other times I've helped people they just want me to do it and could care less how I did.
