Internet trolls are nuts - New psychological research into internet trolls has uncovered some interesting things about their personalities.
The research, conducted by Erin Buckels of the University of Manitoba and two colleagues, sought to directly investigate whether trolls suffer from a Dark Tetrad of Machiavellianism, narcissism, psychopathy and sadism.
The study found correlations, sometimes quite significant, between these traits and trolling.
There was also a relationship between most of the Dark Tetrad traits and the overall time that an individual spent commenting on the internet.
Survey participants were asked what they "enjoyed doing most" when on online comment sites, offering five options: "debating issues that are important to you," "chatting with others," "making new friends," "trolling others," and "other".
