“…[The] ‘illusion of confidence’ is now called the ‘Dunning-Kruger Effect’, and describes the cognitive bias to inflate self-assessment.

To investigate this phenomenon in the lab, Dunning and Kruger designed some clever experiments. In one study, they asked undergraduate students a series of questions about grammar, logic and jokes, and then asked each student to estimate his or her score overall, as well as their relative rank compared to the other students. Interestingly, students who scored the lowest in these cognitive tasks always overestimated how well they did – by a lot. Students who scored in the bottom quartile estimated that they had performed better than two-thirds of the other students!…”
