Up next in this AoIR 2024 conference session is the great Luca Rossi, whose interest is in visual communication strategies in climate change debates. Online debate on these topics tends to be highly polarised between those who do and do not accept the scientific consensus on climate change; it is also difficult to discuss in the abstract, so that visual representations become especially important in these debates.

How do specific images feed into the political narrative on climate change, then: are they used to debate objective facts (e.g. through data visualisations), or in a more polarising way to represent group …

The final speaker in this ECREA 2024 session is Mette Bengtsson, whose focus is on the relationship between Meta and its network of approved third-party fact-checking organisations. Fact-checking has developed considerably around the world in recent years, and there are several global organisations connecting this network – including the International Fact-Checking Network (IFCN).

Meta currently partners with some 90 fact-checking organisations around the world, covering some 60 languages. These can use Meta’s data tools to identify currently circulating claims and select them for assessment; once such assessments have been made, Meta can use them in adjusting its algorithmic ranking of …

My own presentation, on the impact of the 2021 Australian Facebook news ban, was next in this ECREA 2024 session. The slides are available here:

The final day at ECREA 2024 begins for me with a panel on conspiracy theories, and a paper by the great Annett Heft. Her focus is on the diffusion dynamics of conspiracy theories across platforms. She begins by noting the substantial growth in conspiracy theory diffusion, and the severe consequences these ideas can have. Cross-platform activity (involving social media, social messaging, multimedia platforms, alternative news media, and mainstream media) can further heighten this impact.

This project focusses on the two far-right conspiracy theories of the New World Order, with a strong anti-Semitic component, and the Great Replacement / White Genocide …

The next session at ECREA 2024 that I’m attending is on communication in times of illiberalism, and starts with Natalie-Anne Hall. Her focus is on political engagement around Brexit on Facebook, in the post-referendum period between 2017 and 2019. Rather than gathering Facebook content, this study focussed on Facebook users – in recognition of the fact that Facebook remains the leading mainstream social network in the UK.

The post-Brexit context was ripe for populist discursive appeals, which claimed that political elites were attempting to undermine the Brexit referendum results; this was actively fanned by illiberal and often also racist groups …

The next speaker in this ECREA 2024 session is Azade Kakavand, whose interest is in mapping far-right voices across platforms. This is methodologically difficult, and requires a matching of user identities across platforms – especially also because far-right actors are well-known for using multiple platforms for a variety of distinct purposes.

The present study employs the process of user identity linkage (UIL), which was developed in computer science for user profiling, marketing, and cybersecurity purposes. Here, however, the approach is not limited to natural persons but is applied to human and non-human accounts of any kind. The project draws on …

The next ECREA 2024 session is also on polarisation, and I’m chairing as well as blogging it. We start with Petra de Place Bak, whose interest is in the cognitive preferences that make specific types of online content more salient and shareable. One aspect of this might be sentiment- and emotion-based biases.

Petra’s focus is on social media communication, which has to address the twin challenges of information abundance and attention scarcity; this is affected both by platform algorithms and users’ own cognitive preferences. Negative content biases can play a role especially in the latter, as can biases (both positive …

The first full day at the ECREA 2024 conference begins for me with a panel on Telegram and politics. The first presenter is Corinna Peil, whose interest is in COVID-19 conspiracy narratives on Telegram. How do the people who disseminate such narratives understand content moderation interventions?

Content moderation is a fundamental service that social media platforms provide, but this also generates accusations of censorship; exactly how content moderation works is also a subject of (sometimes conspiracist) ‘folk theories’ about the power and practices of social media platforms, however. The pandemic heightened this further, as it pushed platforms to implement stronger …
