I think the main problem is that we are in general unaware of what others do not know. I think we all extrapolate that if we know something, others must also. I'm not sure if that is a great self-centered reflective view we all take or simply optimism for our fellow man. Either way, I find that opportunities are missed because of this. I have many colleagues who are experts in their field but believe that what they know is simply common sense.
