Besides which, the social skills to talk to smart people aren't completely independent of the social skills to talk to not-so-smart people, honestly.
Good luck. Explaining, that "geek culture" required socialization to be a culture, thus geeks are typically quite social, NEVER sinks in. Might as well explain the old implication that geek chicks didn't exist was never meant to be a statement of fact, just an insult to geek males. He's been normalized and as usual is both proud and angry about it, so he needs a target. Nerd/geek/foo cultures are acceptable (ignoring "geek chic" and other hipster quasi-"cool kid" shit...).
There is a minimum IQ (which is fairly low) and above that IQ everyone has an equal chance.
Not equal, just dependent on other things, like definition of "success" for one. Intelligent but sleazy gets you further than intelligent but honest.
