Editor's note: Spending our time as we do up to our necks in climate muckrakery, we know a thing or 300 about squaring off with the trolls of the internet -- specifically with the hairy, spiky, climate-denying variety. Here, Chris Mooney uncovers what we've always suspected: They're verifiable sadists.
In the past few years, the science of internet trollology has made some strides. Last year, for instance, we learned that by hurling insults and inciting discord in online comment sections, so-called internet "trolls" (who are frequently anonymous) have a polarizing effect on audiences, leading to politicization, rather than deeper understanding of scientific topics.
That's bad, but it's nothing compared with what a new psychology paper has to say about the personalities of so-called trolls themselves. The research, conducted by Erin Buckels of the University of Manitoba and two colleagues, sought to directly investigate whether people who engage in trolling are characterized by personality traits that fall in the so-called "Dark Tetrad": Machiavellianism (willingness to manipulate and deceive others), narcissism (egotism and self-obsession), psychopathy (the lack of remorse and empathy), and sadism (pleasure in the suffering of others).
