Unskilled and Unaware of It

Unskilled and Unaware of It: How Dif­fi­cul­ties in Rec­og­niz­ing One’s Own Incom­pe­tence Lead to Inflat­ed Self-Assessments

This quote opens the article:
It is one of the essen­tial fea­tures of such incom­pe­tence that the per­son so afflict­ed is inca­pable of know­ing that he is incom­pe­tent. To have such knowl­edge would already be to rem­e­dy a good por­tion of the offense. ( Miller, 1993, p. 4) 

I found the whole thing fascinating.
