Quite -- except that not only do they not realise the depth of the subject, they don't realise its breadth (i.e. that it encompasses a lot of other subjects) as well.
IMO the person with a narrow field of real expertise is worse than the person who doesn't know much about anything. The graphic designer with a fearsome paper portfolio (but who doesn't know anti-aliasing from his elbow) is harder to argue with than the enthusiast who just wants it to look shiny; the BOFH assumes that if it's got computers in it, he automatically knows better than the ponytailed NuMeeja 'professional', and so on through the list of tedious stereotypes.
Me, I know I'm only just beginning to learn just how much I don't know. But in the country of the blind, the one-eyed man will probably be asked to do all the web-browsing.
