Thus, the correlation between one's objective cognitive abilities and self-assessed abilities is higher at higher levels of objective cognitive abilities. There has been much debate as to whether this effect actually exists or is a statistical artefact. This paper replicates and extends Gignac and Zajenkowski (2020) and Dunkel, Nedelec, and van der Linden (2023) to test whether the DKE exists using several measures of ability and nationally representative data from a British birth cohort study. To do this, we construct a measure of objective cognitive abilities using 18 tests conducted at ages 5, 10, and 16, and a measure of subjective self-assessed abilities using estimates of school performance and being clever at ages 10 and 16. We replicate their models and show that the DKE exists in our secondary data. Importantly, we are the first to look at whether this relationship is heterogeneous by gender and find that while the self-assessment bias is gender specific, the DKE is not. The DKE comes from men relatively overestimating and women relatively underestimating their abilities. date: 2025-03-07 date_type: published publisher: Elsevier BV official_url: https://doi.org/10.1016/j.socec.2025.102362 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2369032 doi: 10.1016/j.socec.2025.102362 lyricists_name: Shure, Dominique lyricists_id: SHURE67 actors_name: Shure, Dominique actors_id: SHURE67 actors_role: owner full_text_status: public publication: Journal of Behavioral and Experimental Economics article_number: 102362 issn: 2214-8043 citation: Adamecz, Anna; Ilieva, Radina; Shure, Nikki; (2025) Revisiting the Dunning-Kruger effect: composite measures and heterogeneity by gender.
