A social psychologist stumbles upon an article about an incompetent bank robber:

As Dunning read through the article, a thought washed over him, an epiphany.  If Wheeler was too stupid to be a bank robber, perhaps he was also too stupid to know that he was too stupid to be a bank robber — that is, his stupidity protected him from an awareness of his own stupidity.

An interesting discussion with this professor, who developed the “Dunning-Kruger Effect.”

Bonus: talk about the usefulness of Donald Rumsfeld’s “unknown unknowns”!
