[T.B. Yoits]

The thing about most stupid people is that they think they are extremely intelligent.

They never get beyond the peak. There is no forward progress toward competence.

One of my heroes, Thomas Sowell wrote a whole book about this: Intellectuals and Society

A great read! In synopsis, educated people think they are experts on not just their specialty, but everything else. And society buys into it.
