Sorry, I've been having a real big problem with specificity lately. I blame it on facebook.

You asked whether it might be mind-projection fallacy that caused him to assume that smart people are socially awkward. The article looks like it is being stereotypical rather than fallacious in some other way.

Of course I might just be projecting, here. :) I do consider myself to be smart, and I definitely try not to think much about socializing. Not that it's done me much good. I end up thinking about it anyway because that's the rational thing to do.
