"If you are absolutely no good at something at all, then you lack exactly the skills that you need to know that you are absolutely no good at it."
Perhaps this is part of the reason that so many education reforms that are attempted fail so badly? Could it be that at least some of the people involved in education reform are just so completely inept that they are not even able to judge their own performance at all?
The good news is, if you know you are bad at something, then at least you are not completely inept, because if you were, you might think you were good at it. The bad news is, people who are completely inept are unable to judge or recognize their ineptness, which may make them push ahead in ways which are harmful to the rest of us.
