I think there's no doubt that VC's will have an inherent bias towards people of similar backgrounds to themselves. Which I think is the biggest problem they have. Sometimes a complete outsider or wacko is what's called for. My favorite example of this is "Moneyball" - there was the conventional wisdom in baseball that was never really examined - it took a complete outsider (Billy Beane and/or Bill James) to really rethink it.
