This research investigates whether the Dark Core of personality (D)—the common aversive essence of all dark traits—is associated with primal world beliefs, which are deep‐seated assumptions about the nature of the world (e.g., viewing the world as safe, meaningful, or beautiful).\n\n\nMethod\nAcross four studies (total N = 2245), latent correlations and latent regression analyses involving D and primal world beliefs were examined.\n\n\nResults\nD was associated with more negative world beliefs, indicating that high‐D individuals tend to hold globally pessimistic worldviews that extend beyond instrumental beliefs serving to reduce cognitive dissonance. That is, high‐D individuals also see the world as less pleasurable, less stable, less regenerative, and less meaningful.\n\n\nConclusions\nSpecifically, the facet Meaningful emerged as uniquely associated with D, suggesting that perceiving many aspects of life as meaningless reflects a broader worldview underlying D—one that extends beyond specific beliefs used to justify aversive behavior.\n\n"]
