Multiple empirical studies confirm that Honesty-Humility from the HEXACO personality model correlates significantly with the Dark Triad traits, often sharing a substantial amount of common variance.
The retrieved literature consistently supports the claim that Honesty-Humility correlates with the Dark Triad traits (Machiavellianism, psychopathy, and narcissism). Several studies show strong negative correlations between Honesty-Humility and the dimensions of the Dark Triad or the dark core, confirming significant overlap and shared variance.
