Global Patterns of Viral Content on WhatsApp

TL;DR

This study analyzes how misinformation and other viral content spread through private WhatsApp groups across three Global South contexts—rural India, Indonesian universities, and Colombia—using a privacy-preserving data-donation approach. Through inductive, region-specific qualitative coding of hundreds of forward messages (with adjacent-message context), the authors reveal cross-cultural similarities in group types and viral narratives, while highlighting country-specific patterns in content focus (religious/political in India, health/religion in Indonesia, regional/political in Colombia). A striking finding is the near-absence of in-group fact-checking or corrective behavior, even for debunked content, underscoring limitations of current fact-checking strategies on encrypted platforms. The paper argues for rethinking misinformation countermeasures—emphasizing grassroots, participatory fact-checking and platform-integrated interventions—to bolster resilience of communities relying on private messaging for information. Overall, the work advances Social Computing by detailing how localized digital practices on WhatsApp interact with global misinformation dynamics and informs policy and platform design for privacy-preserving research and moderation.

Abstract

This paper explores the nature and spread of viral WhatsApp content among everyday users in three diverse countries: India, Indonesia, and Colombia. By analyzing hundreds of viral messages collected with participants' consent from private WhatsApp groups, we provide one of the first cross-cultural categorizations of viral content on WhatsApp. Despite the differences in cultural and geographic settings, our findings reveal striking similarities in the types of groups users engage with and the viral content they receive, particularly in the prevalence of misinformation. Our comparative analysis shows that viral content often includes political and religious narratives, with misinformation frequently recirculated despite prior debunking by fact-checking organizations. These parallels suggest that closed messaging platforms like WhatsApp facilitate similar patterns of information dissemination across different cultural contexts. This work contributes to the broader understanding of global digital communication ecosystems and provides a foundation for future research on information flow and moderation strategies in private messaging platforms.
