us "smart people"
Okay, I'm probably making way too big a deal of this... But goddamnit, I HATE it when people say things like this. It's just elitist, and it annoys me to no end. Did you ever notice how anyone who ascribes to an elitist philosophy always counts themself as a member of the elite? You'll never find a Leninist who doesn't believe he's part of the intellectual vanguard, or an Objectivist who doesn't believe that he is a member of the independent entepreneurial class.
Anyway, as for what WanderingIdiot was saying about Intelligence vs. Knowledge: by that definition one could be intelligent without being knowledgeable; however, one could not be knowledgeable without being intelligent, because being knowledgeable implies a higher capacity to retain knowledge. I've known many people in my life who were just able to memorize facts and then regurgitate them when needed. At no time, however, did they actually THINK. Also, some people who don't have a great ability to gain knowledge or memorize facts are still geniuses. A poet or a composer does not necessarily have to be learned; he just has to be able to connect things together. Beethoven was widely viewed as mentally deficient and an ignoramus, for example.
I think what would work much better would be a threefold division of "smartness": Knowledge, the facts themselves (this is not an ability per se, it's more like intellectual "food"); Intellegence, the ability to gain knowledge easily; and Intellectual Creativity, the only element of "smartness" that is absolutely essential to what we call Genius. Intellectual Creativity is the ability to connect ideas in new, interesting ways.
As for whether Intellegence is genetic, I'd still say that it mostly isn't. Aside from cases of serious genetic defects like Down Syndrome, I'd say that the capacity to acquire knowledge is more socially determined than anything. Descriptions of feral children (i.e. children who grew up in the wilderness seperated from all human contact) seem to indicate that without socialization, a human being would probably function on about the level of, say, a retarded chimpanzee. Society is what makes us human; therefore, almost all attributes that we would consider distinctly human, e.g. intelligence, are determined by society.
