Abstract: 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) × 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. © The Author(s) 2020.
