From my experience the boss does not know things you know, that does not make them a complete moron because they probably know things you don't.

Here's an example, consulting at a large Danish company, every Friday morning all departments in this big building would share breakfast and the bosses would say some things.

So this one morning they explained that in the coming months people should register time in a particular way because of accounting and how it related to a particular government grant and money that needed to be used up by a particular time in order to get to the next step of blah blah blah.

I realized as my eyes glazed over, damn this is just the same reaction people who don't understand browser rendering engines get when I start telling them about different events.

I also noticed other clueless people gamely trying to question these finance nerds on how things worked, and the patient finance nerds explaining some detailed bit and the clueless person clearly out of their depth with that "uuuuhhhh, hope they don't ask me if I understand" look on their face.

Now, if it hadn't been for them explaining this stuff I would have gone around thinking the boss is a complete moron. I once saw him mistake a nail gun for a drill! He doesn't understand how search engines work and why stemming and decompounding might be important, I know because I tried to explain to the idiot one time!! But since he actually talked about his work for a bit I realized he just happens to know stuff I don't.

I'm betting most of the morons you know are maybe not quite so stupid, although probably not as forthcoming as why things need to be done in a certain way to those who work under them.
