The participants’ knowledge of geography was tested; some tests were intended to positively affect the participant’s self-view and some were intended to affect it negatively.

With more difficult tasks, the best performers were less accurate in predicting their performance than were the worst performers. Further explorations of absent self-insight among the incompetent”.

Moreover, competent students tended to underestimate their own competence, because they erroneously presumed that tasks easy for them to perform were also easy for other people to perform.
