The tangled webs they weave: A scoping review of deception detection and production in relation to Dark Triad traits.

People deceive for different reasons, from avoiding interpersonal conflicts to preserving, protecting, and nurturing interpersonal relationships, and to obtaining social status and power. A growing body of research highlights the role of personality in both deception detection and production, with a particular focus on high Dark Triad (DT) traits (Narcissism, Machiavellianism and Psychopathy), for their shared tendency to engage in unethical self-benefitting behaviors, despite negative consequences for others. The main goal of the current scoping review was to bring together the studies investigating self-reported and performance-based deception production and detection performances, as presented in individuals characterized by high DT traits and point out the possible contribution of DT to deception research. To do so, we identified the relevant studies documenting the similarities and discrepancies between the three personality traits and presented their results, based on the procedure used for deception assessment: subjective or objective measurements for production / detection. Then, we discussed possible explanatory mechanisms for inter-individual differences in lie detection / production and argue for the contribution of DT to deception research beyond the typical personality models, particularly for the antisocial character of deception.
