Empirical evidence supports the Dunning-Kruger effect
While foundational studies and several recent empirical papers find evidence of the Dunning-Kruger effect where low performers overestimate their abilities, recent methodological critiques argue that the pattern may partly stem from statistical artifacts and regression toward the mean, leading to an ongoing debate.
The claim that empirical evidence supports the Dunning-Kruger effect is contested in contemporary literature. While classic studies (e.g., Paper 0) and several applied fields (e.g., Papers 3, 5, 10) report supportive correlations and overestimation by low performers, recent rigorous psychometric papers challenge these findings. Specifically, Paper 2 refutes the underlying dual-burden account as a statistical regression artifact, and Paper 7 demonstrates that the effect depends heavily on whether classical or advanced statistical methods are used.

Demonstrates that poor performers grossly overestimate their performance due to a lack of insight into their errors.

Refutes the dual-burden account, suggesting the classic Dunning-Kruger pattern is largely a statistical regression artifact.
