Exact replication of Kozłowska et al. (2023) “The Napoleon complex, revisited”: Contrary evidence in a 2.6 times larger sample

Year: 2025

Type: article

Abstract: The present study ( N = 943) aimed to exactly replicate the study of Kozłowska et al. (2023; N = 367), in which it was found that Dark Triad traits (i.e., psychopathy, narcissism, and Machiavellianism) were associated with shorter body height and wishing to be taller. The present study found an association between Dark Triad traits and wishing to be taller but no association between Dark Triad traits and a short body height. Contrarily, an association between tall body height and narcissism and psychopathy was found. Overall, the effect sizes were smaller than those reported by the original study. The results are discussed by comparing the replication and original study while considering the current knowledge of the relationship between Dark Triad traits and physical characteristics.
