Gratitude Blindness: How does the Dark Triad experience gratitude?

Gratitude promotes prosociality and long-term reciprocal relationships. The Dark Triad is associated with maladaptive interactions in their social and interpersonal relationships. The present study aimed at understanding whether these individuals experience gratitude at state and trait levels, when presented with situations that differentially benefit them. The Dark Triad, specifically psychopathy and Machiavellianism, is negatively associated with trait gratitude. In situations where others are uncooperative towards them, individuals with Dark Triad traits, specifically Machiavellianism and narcissism, report poorer state gratitude. Implications are discussed, particularly in light of the Dark Triad as a defector personality hindering reciprocal altruism.
