"Few 'Supersharers' Drive Majority of Misinformation on Twitter"
Two studies published in Science reveal that a small group of "supersharers," primarily older Republican women, were responsible for spreading 80% of misinformation on social media during the 2020 election. The MIT study highlights that exposure to vaccine misinformation significantly reduces vaccination intent, with unflagged misleading content having a greater overall impact than flagged misinformation. The second study identifies 2,107 U.S. voters as the primary spreaders of political fake news, demonstrating the outsized influence of a few individuals on social media.
