Facts are hard to come by: discerning and sharing factual information on social media

How credulous are we when engaging information on social media? Addressing this question, this article aims to understand how individuals’ epistemic vigilance, a set of cognitive mechanisms that comprise our system of precaution in social interactions, may operate and fall short. Reporting findings from two survey experiments (Study 1, N = 413; Study 2, N = 392), we show that participants tended to be skeptical toward social media news, were reasonably successful in identifying true news, and reported a tendency to share true rather than false news. In one study, social endorsement enticed a higher accuracy rating of news posts. In both studies, people judged attitudinally congruent news posts as being more accurate and reported a higher likelihood to share them. Individuals’ propensity to reflective thinking measured by cognitive reflection test potentially operated as a restraint on sharing inaccurate information and bolstered veracity anchoring in their information engagement.
