I recall hearing a Peter Theil interview a couple of years ago where he hypotheses that social awkwardness is over-represented in successful founders because such people have been conditioned to heavily discount mainstream opinions. More socially integrated would-be entrepreneurs are more likely to listen to all the nay-sayers, "that's will never work", "who would want that?", "come join this investment bank/management consultancy with the cool kids" and never start the company.
