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

Abstract

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.
