>> You can be an expert in one things and a beginner in another at the same time. That's apparent or implied mastery. Psych friend says it happens all the time, executive type comes to therapy. He's a master at his business, has all sorts of industry experience, really knows his stuff, but then has trouble in say... personal relationships because he's absolutely clueless on those types of things. Mastery in one area does not imply it in another. So when you think "this person is really smart, why are they making xxx stupid decision?" just check if the reason you think they are smart is in any way related to the area of the stupid decision ;-)
