Where can I learn more about what "multi-vector correlation" means in this context?

Er, sorry. I'm sure I've mangled whatever legitimate mathematical jargon that resembles. What I mean is that intelligent people tend to have more knowledge and knowledgeable people tend to be more intelligent. By "multi-vector" I just mean that this co-variability isn't due to one simple factor or explanation but that lots of factors are responsible for the correlation. Intelligent people learn more, those raised in environments with lots of knowledge to pick up are more likely to have had intelligent parents, etc.

I tend to think of that as a lack of rationality. (I assume we're talking about someone who, say, simply refuses to change their standard response to a situation once they've made a semi-public announcement of it. This could also be explained by saying they're rational, but with a complex utility function.)

What I mean is: say there is some task that needs to be completed an intelligent will immediately see one of the better ways of completing the task and will routinely improve on the methods of the less intelligent. The less intelligent won't even always recognize what makes the new solution better.
