Research from Brigham Young University sheds light on the motives and personality characteristics of internet trolls. Individuals with dark triad personality traits (narcissism, Machiavellianism, psychopathy) combined with schadenfreude were more likely to demonstrate trolling behaviors. Women who participated in the survey viewed trolling as dysfunctional while men were more than likely to view it as functional. The study found no correlation between being outspoken online and trolling behavior. The findings are encouraging and suggest that civil online discourse is attainable.
