Social Media's Effect on Elections.

Social media had only a small influence on how much people believed falsehoods about candidates and issues in the last two presidential elections, contends a pair of studies at Ohio State University. Moreover, study author R. Kelly Garrett, professor of communication, contends that Facebook--which came under fire for spreading misinformation in the 2016 campaign--actually reduced misperceptions by users in that election compared to those who consumed only other social media.

Obama than Democrats did, while Democrats held less-accurate beliefs about Romney than did Republicans. Results showed that increasing social media use reduced participants' belief accuracy about Obama falsehoods, although the effect was small.
