Tweeters tend to share fact checks that confirm their partisan biases

Drawing upon a Twitter dataset from the 2012 United States presidential election, this study examines the motives that partisan social media have to share fact checks. Researchers analyzed messages and comments related to fact checks posted on the Twitter accounts of PolitiFact, Factcheck.org and The Washington Post Fact Checker in Oct. 2012, when several debates were took place. Specifically, they looked at 93,578 comments from 55,869 unique Twitter users on 194 original fact checks, coded how each party would perceive the ratings and used a computational approach of users' past tweets to evaluate their political leanings. The study found that fact checks that were positive for the ingroup party were shared more by ingroup members than outgroup members. In short, people shared the fact checks that played into their partisan biases.
