Aim of the study:
Our study examined how broad personality traits, such as the HEXACO model, relate to prosocial (Light Triad) and aversive (Dark Triad) tendencies.

Subject or material and methods:
A sample of 187 Brazilian adults (M = 31.39, SD = 11.54) completed measures of the HEXACO, the Light Triad, and the Dark Triad.

Results:
Honesty-Humility showed medium negative correlations with the Dark Triad, whereas agreeableness and extraversion were positively associated with the Light Triad. A restricted path model demonstrated distinct prediction patterns. Agreeableness positively predicted all Light Triad traits, whereas conscientiousness negatively predicted all Dark Triad traits.

Discussion:
These findings reinforce that the Light and Dark Triads are not opposite ends of a single continuum.

Conclusions:
Instead, they are grounded in different dispositional systems, with the Dark Triad linked to impulsive and antagonistic tendencies and the Light Triad associated with interpersonal warmth and prosocial orientations.
