This study examined the relationship of the Dark Tetrad with core values, and the role of honesty-humility as a moderator of the “dark” personality-core values link. A sample of 183 participants (57 male, 126 female; Mage=18.39years, SD=1.12) completed an online survey assessing the Dark Tetrad, the 10 values from the Schwartz Value Typology, and honesty-humility from the HEXACO. Several Dark Triad-core value correlations were replicated. Furthermore, some of the predicted links between sadism and values were also corroborated using both novel and established sadism measures. The moderating role of honesty-humility on the link between each Dark Tetrad member and aggregated core values was explored. Honesty-humility moderated only the following relationships: psychopathy and Self-Enhancement Plus Openness to Change values, and narcissism and Self-Enhancement Plus Openness to Change values. These findings contribute to understanding how personality traits and values describe people's behaviour in interpersonal contexts.
