Abstract

Kruger and Dunning (1999) demonstrated that those who are less competent in a specific domain are more likely to overestimate their performance. In the current research, this so-called Dunning-Kruger effect was replicated in a real-life academic context with data collection in an undergraduate course. Right after the final exam, students estimated their performance. Comparisons of these estimates with actual scores revealed Dunning-Kruger effect. A pattern emerged in which, effort in exam preparation had both an indirect, decreasing effct and a direct, increasing effect on overestimation. An alternative explanation of Dunning-Kruger effect that it is an artifact caused by perceived difficulty was not supported, and whether performance estimation was made at a more specific or a more abstract level did not lead to a significant difference in the degree of overestimation. In sum, the results of this study is more consistent with Kruger and Dunning's (1999) ‘metacognition’ account than either ‘regression to the mean’ account (Krueger & Mueller, 2002) or ‘task difficulty’ account (Burson, Larrick, & Klayman, 2006). Alternative explanations, limitations of the study, and future directions are discussed.
