Purposes of this study are to test the effects of dark triad on humor styles and to inquire about the inconsistent relations previously reported between narcissism and self-enhancing humor on a sample from Türkiye. Data for this research is collected from white-collar employees working in various companies through an online questionnaire. To measure research variables, Humor Styles Questionnaire and Dirty Dozen Dark Triad inventory are used. Structural Equation Modeling was employed to test the research hypothesis. The results indicated that narcissism positively affects all humor styles, Psychopathy has a positive effect on aggressive, self-defeating and self-enhancing humor styles and Machiavellianism has a negative effect on self-defeating humor. The study discusses the implications of these results and provides suggestions for future research.
