Interesting. Perhaps the comment about not being able to learn from people who don't have these clearances also applies to highly knowledgeable individuals in any field that have trouble listening to people with less information or understanding of matters. Perhaps it even explains how years of "knowing more" can lead to resistance to change (the kind that I've found to be characteristic of bad professors or some people I used to work for)

I think it's important to be aware of this. If I ever find myself not listening to someone because I think the person doesn't know all the facts, I hope that I'll become aware of it and try to zero in on what facts they are missing. Luckily I know very few secret things (I have even been known to intentionally make secret things un-secret) so I'd gladly share those facts and see for myself if it changes the other person's opinion.
