本研究从媒体效应和可信度评估的角度扩展了“轻推”原则，以检验事实核查警报阻止社交媒体上新闻分享的有效性是否受到新闻来源的调节，以及这种调节是否以用户对主流媒体的怀疑为条件。结果从2（轻推：事实核查警报与无警报）× 2（新闻来源：传统主流与陌生的非主流）（N = 929）实验控制个人问题的参与，在线新闻参与，新闻分享经验，揭示了显着的主要和交互作用的影响，这两个因素。非主流新闻的新闻分享可能性总体上低于主流新闻，但在推动时，主流新闻的新闻分享可能性下降幅度更大。没有发现来自媒体怀疑论的有条件缓和;相反，用户对主流媒体的怀疑论只放大了传统主流媒体的新闻，而不是不熟悉的非主流来源的新闻。讨论了在社交媒体中使用事实核查和主流新闻来源的理论和实践意义。
This study extends the nudge principle with media effects and credibility evaluation perspectives to examine whether the effectiveness of fact-check alerts to deter news sharing on social media is moderated by news source and whether this moderation is conditional upon users' skepticism of mainstream media. Results from a 2 (nudge: fact-check alert vs. no alert) x 2 (news source: legacy mainstream vs. unfamiliar non-mainstream) (N = 929) experiment controlling for individual issue involvement, online news involvement, and news sharing experience revealed significant main and interaction effects from both factors. News sharing likelihood was overall lower for non-mainstream news than mainstream news, but showed a greater decrease for mainstream news when nudged. No conditional moderation from media skepticism was found; instead, users' skepticism of mainstream media amplified the nudge effect only for news from legacy mainstream media and not unfamiliar non-mainstream source. Theoretical and practical implications on the use of fact-checking and mainstream news sources in social media are discussed.
