The Impact Of Social Media Platforms On Public Opinion Formation During Crises: An Applied Study

Abstract

This applied study investigates the multifaceted impact of social media platforms on public opinion formation during crisis events. Drawing on recent cross-national empirical evidence and platform-specific analyses, the research identifies four primary mechanisms through which digital platforms exert influence: (1) the temporal compression of the public agenda, wherein social media dictates issue salience within the critical first 24 hours of a crisis—significantly outpacing traditional media; (2) the algorithmic amplification of misinformation, which, driven by emotional user responses, systematically undermines institutional credibility; (3) the reinforcement of opinion polarization and echo chambers, where algorithmic curation and fear of social isolation limit exposure to dissenting views; and (4) significant cross-cultural divergence in public sense-making, demonstrating that trust in government fundamentally shapes the thematic focus of online discourse across different national contexts.

Empirically, the study applies these findings to real-world cases, including the analysis of crisis communication strategies on Douyin/TikTok, which reveals how short-video platforms reconfigure public responsibility attribution through emotional and visual affordances. The findings further confirm that organizational responses on digital platforms frequently lack strategic alignment with established crisis communication models, often unintentionally escalating reputational risk. The study concludes with actionable recommendations for crisis practitioners, emphasizing the necessity of rapid authentic communication, culturally contextualized messaging, and proactive collaboration with independent fact-checkers and trusted digital influencers to navigate the complexities of algorithm-driven public spheres.
