Replication Data for: Examining Partisan Asymmetries in Fake News Sharing and the Efficacy of Accuracy Prompt Interventions

The spread of misinformation has become a central concern in American politics. Studies using social media data show that Republicans share considerably more misinformation than Democrats. However, such inferences are confounded by the greater supply of right-leaning misinformation--Republicans may not be more prone to sharing misinformation; rather, they may simply be more exposed to it. We test competing explanations for why Republicans share more misinformation online in a balanced information environment. We show that Republicans are more prone to sharing ideologically agreeable misinformation, but that this asymmetry is not nearly large enough to explain differences observed on social media. Our findings suggest that the remaining asymmetry is not due to Republicans being worse at identifying misinformation or caring less about accuracy. Encouragingly, we find that accuracy prompt interventions are equally effective at reducing the spread of misinformation across parties, suggesting that misinformation sharing among Republicans is not an intractable problem.
