"Online discussions are dominated by a surprisingly small, extremely vocal, and non-representative minority. Research on social media has found that, while only 3 % of active accounts are toxic, they produce 33 % of all content [...] 0.1 % of users shared 80 % of fake news [6,7]. Not only does this extreme minority stir discontent, spread misinformation, and spark outrage online, they also bias the meta-perceptions of most users who passively “lurk” online."
