I presented the next paper at the AoIR 2025 conference, presenting the reflections of a large QUT team on how we might study election discussions across a wide range of social media platforms in the increasingly fragmented online platform environment. Here are our slides:

My own presentation on behalf of the Laureate team was next in this session at the AoIR 2025 conference, exploring a similar dataset on climate discussions on Facebook between 2018 and 2024 in Australia. Here are the slides:

The last day of the excellent AoIR 2025 conference in Rio de Janeiro starts with our panel on climate change communication in Australia and Brazil – two countries which have quite a few similarities in this context: they’re both highly exposed to extreme weather events, have stressed environments in the Amazon and Great Barrier Reef, and and are major fossil fuel exporters. We start with my excellent colleague Tariq Choucair, whose focus is on the discussion of extreme climate events in social media environments.

Extreme weather experiences affect and are affected by individual perceptions and attitudes towards climate change. Individuals …

The second presenter in this session at the AoIR 2025 conference is Felipe Soares, whose focus is on the Bolsonarist coup attempt in Brazil on 8 January 2022. This occurred after Bolsonaro’s close election loss in November 2022, which Bolsonaro disputed and which led his supporters to call for military intervention. By now, Bolsonaro has been sentenced to 27 years in prison for this coup attempt.

These events can be seen as a clear sign of deep-set destructive polarisation in Brazil: there is a breakdown of communication between the sides, an emotional exclusion of others, and a dismissal of information …

The final session today at the AoIR 2025 conference starts with my excellent QUT colleague Tariq Choucair, who begins by introducing the challenge of assessing polarisation: there are many different definitions of polarisation, which require different measures of assessment. Most current methods fail to sufficiently distinguish between these types of polarisation.

Tariq is therefore proposing a new approach to assessing polarisation, which he has applied to the study of national electoral contests in Australia, Brazil, Denmark, and Peru. The focus here is to identify polarising rhetoric, including campaign attacks, and polarisation in broader public debates.

The method focusses especially on …

The final speaker in this session at the AoIR 2025 conference is the brilliant Fabio Giglietto, presenting a study of pro-Bolsonaro narratives on Facebook in Brazil. The key question here is whether online hyperpartisan groups are as stable as they are thought to be; is that true, and how does such stability fare in times of intense political crisis?

Brazil is an obvious case for the study of such questions. The project tracked some 59 pro-Bolsonaro accounts between 2021 and 2023, a timeframe including Bolsonaro’s election loss against Lula and his subsequent coup attempt. The dataset contains some 12 million …
