Abstract: This study examines the impacts of news veracity, source credibility, collective social endorsement, and perceptions of Twitter's utility on perceived credibility of and engagement with social media news posts. We conducted a 2 (Veracity: real vs. fake) × 2 (Source Credibility: credible vs. non-credible) x 2 (Collective Social Endorsement: high vs. low) online experiment (N = 271). In processing news posts, news veracity and source credibility influenced users' perceptions of post credibility, in that real news posts from credible sources were perceived as more credible than fake news posts from non-credible sources. Contrary to previous findings, social endorsement cues did not affect users' perceptions of post credibility or news engagement intent. More importantly, users' perceptions of Twitter's helpfulness in staying informed were associated with post credibility and intent to ‘like’ or share. Users with higher perceptions of Twitter's helpfulness were more likely to perceive posts as credible and more likely to engage with posts on social media. The results of this study have important implications for future research on news assessment and spread on social media.
