Key misinformation “superspreaders” on Twitter: Older women

Misinformation is not a new problem, but there are plenty of indications that the advent of social media has made things worse. Academic researchers have responded by trying to understand the scope of the problem, identifying the most misinformation-filled social media networks, organized government efforts to spread false information, and even prominent individuals who are the sources of misinformation.

All of that's potentially valuable data. But it skips over another major contribution: average individuals who, for one reason or another, seem inspired to spread misinformation. A study released today looks at a large panel of Twitter accounts that are associated with US-based voters (the work was done back when X was still Twitter). It identifies a small group of misinformation superspreaders, which represent just 0.3 percent of the accounts but are responsible for sharing 80 percent of the links to fake news sites.

While you might expect these to be young, Internet-savvy individuals who automate their sharing, it turns out this population tends to be older, female, and very, very prone to clicking the "retweet" button.
