Yup!
Incompetent people are, by definition, INCAPABLE of realizing their incompetence.
I seem to recall someone doing a study a while back...
Ah, here it is...

Dunning, a professor of psychology at Cornell, worries about this because, according to his research, most incompetent people do not know that they are incompetent.
On the contrary. People who do things badly, Dunning has found in studies conducted with a graduate student, Justin Kruger, are usually supremely confident of their abilities -- more confident, in fact, than people who do things well.
One reason that the ignorant also tend to be the blissfully self-assured, the researchers believe, is that the skills required for competence often are the same skills necessary to recognize competence.
"Not only do they reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the ability to realize it," wrote Kruger and Dunning.
This deficiency in "self-monitoring skills," the researchers said, helps explain the tendency of the humor-impaired to persist in telling jokes that are not funny, of day traders to repeatedly jump into the market -- and repeatedly lose out -- and of the politically clueless to continue holding forth at dinner parties on the fine points of campaign strategy.
In a series of studies, Kruger and Dunning tested their theory of incompetence. They found that subjects who scored in the lowest quartile on tests of logic, English grammar and humor were also the most likely to "grossly overestimate" how well they had performed.
In all three tests, subjects' ratings of their ability were positively linked to their actual scores. But the lowest-ranked participants showed much greater distortions in their self-estimates.
Asked to evaluate their performance on the test of logical reasoning, for example, subjects who scored only in the 12th percentile guessed that they had scored in the 62nd percentile, and deemed their overall skill at logical reasoning to be at the 68th percentile.
