Conservatives Bombarded With Facebook Misinformation Far More Than Liberals In 2020 Election, Study Suggests

According to new research published Thursday, conservatives on Facebook during the 2020 presidential election were more isolated and saw more misinformation than the platform’s liberal users — though Facebook widely affected users’ political content in different ways. Slashdot reader RUs1729 shared one of the four peer-reviewed studies, appearing in the journals Science and Nature. Forbes reports: The study, led by two researchers from the University of Texas and New York University, had hundreds of thousands of participants and analyzed mass amounts of Facebook user data. One of the study’s papers, which used aggregated data for 208 million U.S. Facebook users, found that most misinformation on Facebook existed within conservative echo chambers, which did not have an equivalent on the liberal side of the platform. The paper found that news outlets on the right post a higher fraction of news stories rated false by Meta’s third-party fact-checking program, meaning conservative audiences are more exposed to unreliable news.

In a separate paper that assigned users to Facebook and Instagram feeds chronologically instead of algorithm-based feeds, which are the platforms’ default feed types, researchers found users on chronological feeds were less engaged and saw more political content compared to those viewing algorithm-based feeds, along with more content from untrustworthy sources and more content from ideologically moderate friends and sources with mixed audiences. However, the feed analysis noted replacing algorithmic feeds with chronological ones did not create any detectable changes in political attitudes, knowledge or offline behavior.

Another paper assigned nearly 9,000 U.S.-based Facebook users feeds with no reshares, later concluding that the removal of reshared content “substantially” lessened the amount of political news, and content from all untrustworthy sources decreased overall. The two lead researchers and 15 other academics, who had control rights for the study’s papers, declined compensation from Meta to ensure an ethical study was completed.
