What’s the Norm Around Here? Individuals’ Responses Can Mitigate the Effects of Misinformation Prevalence in Shaping Perceptions of a Community

Paper Information

• Research Area: Social Computing, Rumor Propagation, and Community Norms
• Keywords: Social Norms, Misinformation, Conspiracy Theories, Community Governance, Human-Computer Interaction, Anti-Vaccine Content, Online Communities

Research Background and Problem

• Issues and Challenges:

  • Conspiracy theories and related misinformation are significantly impacting the ecosystem of online communities, leading to distrust in science and authority and deteriorating social interactions.
  • While technical solutions (e.g., fact-checking, visibility control) exist to address the spread of misinformation, these methods primarily focus on the individual level, neglecting the impact at the community level.
  • It remains unclear which factors within a community influence the perception of "community norms" and how misinformation generates cascading effects at the group level.

• Significance:

  • Perceived community norms influence individuals' understanding of acceptable behaviors within a community, further shaping members' actual behaviors and attitudes.
  • Exploring these mechanisms can help develop effective community-level governance strategies to mitigate the negative impacts of rumors and misinformation.

• Research Motivation and Related Work:

  • Existing studies show that perceived community norms significantly influence decision-making behaviors (e.g., drinking habits, privacy disclosures). When facing conspiracy theories, community norms can better guide individuals in addressing such challenges.
  • The motivation lies in systematically understanding the mechanisms behind the formation of perceived norms in communities and exploring effective ways to curb the spread of misinformation.

Solution

• Methodology:

  • Propose three community factors that may influence the perception of community norms, including: (1) the prevalence of conspiracy theory content; (2) community members' responses to such content (support or opposition); (3) explicit expression of community rules.
  • Conduct two group experiments to study the above mechanisms. These experiments simulate online communities to explore how these factors influence perceived norms and their extended effects.

• Innovative Contributions:

  • Shift the focus to community-level research rather than an individual perspective, emphasizing the potential importance of community members' responses in curbing misinformation.
  • Design a social media experimental platform (EatSnap.Love) to provide a more realistic experimental environment.
  • Explore the impact of "perceived norms" on community tolerance, escalated behaviors, and sympathy toward other conspiracy beliefs.

• Implementation Steps/Key Techniques:

  1. Experiment 1: Use static "screenshot" experiments to simulate online communities and examine the impact of the proportion of anti-vaccine content, comment responses, and explicit rules on perceived norms.
  2. Experiment 2: Use the simulated platform EatSnap.Love, allowing users to experience traditional social media interactions. This enhances the interactive context to validate the conclusions of Experiment 1 and expand the research model.
  3. Data Analysis: Employ structural equation modeling (SEM) to quantify the influence of various variables.

Research Findings

• Key Conclusions and Data Support:

  • Frequency Influences Norms: Even a low proportion of conspiracy theory content sharing (e.g., 30%) significantly affects the community's acceptance of such behaviors, indicating that even minimal sharing can have a substantial impact on perceived norms.
  • Critical Role of Community Responses: Community members' opposition to anti-vaccine content effectively mitigates the negative impact of such content on perceived norms, with a particularly significant influence on adjusting perceptions.
  • Limitations of Community Rules: Explicitly displaying community rules (e.g., opposing misinformation) did not directly affect the perception of norms.

• Advantages Over Existing Methods: Compared to technical tools (e.g., algorithmic interventions, reducing rumor visibility), this study emphasizes the importance of community responses and member involvement. It highlights the necessity of community-level governance to alter group behaviors and perceptions.

• Extensions of Experimental Results:

  • Perceived norms influence broader behavioral expectations, including:
    1. Social tolerance toward conspiracy theories.
    2. Escalated behaviors within and outside the community (e.g., online support for rumors or attending anti-vaccine rallies).
    3. Judgments of other related conspiracy beliefs.

• Limitations and Future Directions:

  1. Application to Heterogeneous Communities:
     • Current experiments focus solely on homogeneous anti-vaccine content scenarios. Future research could examine the impact of mixed content (e.g., coexistence of pro- and anti-vaccine content) on community perceptions.
  2. In-depth Exploration of Rule Impact Mechanisms:
     • Community rules did not intuitively affect perceived norms, possibly due to the way rules were expressed or the short duration of the experiment. Future studies could design rule reinforcement based on actual community behaviors and extend the experiment duration.
  3. Research on Social-Psychological Dynamics:
     • Investigate how long-term community belonging (e.g., senior users) further moderates the formation of perceived norms.

Conclusion

• This study demonstrates that perceived norms are a critical mechanism for understanding how online communities handle conspiracy theories and their dissemination. Community members' responses play a particularly important role in mitigating the community-level impact of misinformation.
• Proposed methods to enhance community participation, such as fostering member interactions and highlighting key comments, can inform the design of better online community governance policies.
