Transnational Diffusion of COVID-19 Conspiracy Theories and Misinformation on Facebook

Core Concepts

The study maps the spread of COVID-19 conspiracy theories and misinformation in Spanish and French across Latin American and French-speaking communities on Facebook, highlighting how shared cultural and thematic attributes among Facebook groups enabled the emergence of large, networked audiences that transcended national borders.

Abstract

The study analyzes the online diffusion of COVID-19 conspiracy theories and misinformation across the Global South by comparing two cases:

The diffusion of COVID-19 conspiracy theories among Latin American countries and Hispanic communities on Facebook related to the Médicos por la Verdad (MPV) organization.
The diffusion of COVID-19 misinformation across francophone countries fueled by remarks made by French microbiologist Didier Raoult (DR) regarding the alleged efficacy of hydroxychloroquine.

The findings show that co-sharing behavior of public Facebook groups created transnational networks by sharing videos of MPV conspiracy theories in Spanish and DR-related misinformation in French. These networks were enabled primarily by shared cultural and thematic attributes among Facebook groups, effectively creating very large, networked audiences.
The study employs Exponential Random Graph Models (ERGMs) to statistically determine which nodal attributes are significant in explaining the emergence of network ties. The results indicate that cultural similarity among groups' nationalities has a noticeable effect on the likelihood of tie formation in both networks. Language similarity yields a negative effect in the MPV data and a non-significant estimate in the DR network. Geographic proximity also varies between case studies, with likelihood of tie formation increasing with geographical co-location in the DR network but yielding non-significant estimates in the MPV network.
The study also finds that thematic similarity, particularly the tendency towards tie formation between Conspiracy Theory groups and Community groups, suggests the superlative diffusion power that dedicated conspiratorial and misinforming Facebook groups have over other non-dedicated, unassuming groups and their audiences.

Stats

The study analyzes Facebook data of non-geolocated posts made by public groups containing mentions of "Médicos por la Verdad" or "Natalia Prego" for the MPV case in Spanish, and "Didier Raoult" or "hydroxychloroquine" for the DR case in French, from February 1, 2020, until October 1, 2021, with audiovisual content.

Quotes

"The findings show that co-sharing behavior of public Facebook groups created transnational networks by sharing videos of Médicos por la Verdad (MPV) conspiracy theories in Spanish and hydroxychloroquine-related misinformation sparked by microbiologist Didier Raoult (DR) in French, usually igniting the surge of locally led interest groups across the Global South."
"The study contributes to the understanding of how potentially harmful conspiracy theories and misinformation transcend national borders through non-English speaking online communities, further highlighting the overlooked role of transnationalism in global misinformation diffusion and the potentially disproportionate harm that it causes in vulnerable communities across the globe."

How can platform moderators and policymakers leverage network analysis techniques to develop more effective strategies for detecting and mitigating the spread of extremist content in non-English speaking online communities?

Platform moderators and policymakers can leverage network analysis techniques to develop more effective strategies for detecting and mitigating the spread of extremist content in non-English speaking online communities by:

Identifying High-Risk Nodes: By analyzing the structure of online networks using network analysis techniques, moderators can identify high-risk nodes, such as Conspiracy Theory groups, that serve as brokers in disseminating extremist content. Targeting these nodes can disrupt the spread of extremist narratives.

Understanding Information Flow: Network analysis allows for a deeper understanding of how information flows within online ecosystems. Platforms can track the propagation of extremist narratives and identify key pathways through which they spread, enabling targeted interventions to prevent rapid dissemination.

Assessing Cultural and Linguistic Factors: By considering cultural and linguistic factors in online interactions, platforms can tailor moderation efforts to specific linguistic and cultural contexts. Understanding the dynamics of different communities helps in developing more effective strategies to combat extremism and misinformation.

Monitoring Thematic Similarity: Emphasizing thematic similarity as a significant factor in tie formation in online networks can help platforms track specific topics and themes associated with extremism. By monitoring the spread of extremist narratives across thematic boundaries, platforms can detect emerging trends and intervene to prevent the escalation of extremist activity.

Integrating Geographical Proximity: Considering geographical proximity in moderation efforts can help platforms address extremism at the regional level. By accounting for the geographical distribution of users and the impact of local context on misinformation and extremist activity, platforms can develop nuanced strategies to combat extremism effectively.
