A systematic literature review of the relationship between dark personality traits and antisocial online behaviours

Abstract

The sub-clinical personality traits of narcissism, psychopathy, Machiavellianism, and everyday sadism (i.e., the dark triad/tetrad) are known to predict subversive behaviours. Given increases in the prevalence of social media and internet use, and the growing knowledge about the negative consequences of their use, it is important to understand how these traits relate to online behaviours. We conducted a systematic review of the evidence for these relationships and found 26 studies which reveal these traits are related to trolling, cyber-aggression, cyber-loafing, sending unsolicited explicit images, the non-consensual dissemination of ‘sexts’, cyberbullying, problematic social media usage, problematic online gaming, problematic internet use, internet-use disorder, social media addiction, intimate partner cyberstalking, technology facilitated sexual violence, and technology facilitated infidelity. The review revealed evidence that psychopathy is the trait most strongly associated with these behaviours - Machiavellianism and everyday sadism were also consistently related to these behaviours, albeit to a lesser degree. Narcissism is the trait least consistently related to antisocial online behaviours.
