The third speaker in this session at the ZeMKI 20th anniversary conference in Bremen is Michael Brüggemann, whose focus is on the role of journalism in fuelling discursive polarisation. He begins by referencing controversial public debates about radical climate protests, which usually evidence some level of discursive polarisation. Such polarisation may be ideological and/or affective, and and become destructive for public debate.

This contrasts with democratic transformative communication, which enables societies to address such conflicts productively. Literature has identified a number of factors that may polarise or depolarise; interestingly, exposure to dissonant views is often seen as polarising, but this …

I was next at the ZeMKI 20th anniversary conference in Bremen, presenting our practice mapping approach to the study of destructive polarisation in public communication. Here are the slides, and I’ve linked to the relevant articles here too:

I’m speaking in the next session at the ZeMKI 20th anniversary conference in Bremen, which is on deliberation and polarisation, but we begin with Hilke Brockmann, whose focus is on ‘echo chambers’ amongst political elites. These are believed to be a risk to democratic processes, and driven by algorithmic processes; but these ideas have rightly been challenged in recent years. We would do better to focus on polarised interactions between political elites, and especially on the margins of the political environment, and this may be intensified by external political events.

The present study examined this by assessing tweets by all …

The final speaker in this session at the ZeMKI 20th anniversary conference in Bremen is Stef Aupers, focussing on online conspiracy theories. These are not individual, but collectively shared, discussed, and shaped on social media. Existing research often focusses on platforms conspiracism, emphasising the role of technological features and platform affordances; what is much less frequently examined are the active and collective meaning-making practices through which groups of conspiracy theorists construct their online social identities.

This represents a participatory conspiracy culture which enables the social construction of identity; it performs boundary work through which conspiracist communities define and policy the …

For the first paper session at the ZeMKI 20th anniversary conference in Bremen I am in a session on disinformation and conspiracies, which starts with Marilia Gehrke and Eedan Amit-Danhi, whose focus is on gendered disinformation. Gendered disinformation includes manipulated images, using image editing and increasingly also generative AI; this often references sexuality and personal identity.

Much of the scholarship to date has tended to focus on gender or disinformation, but not on both together; it also tends to focus on intentionality, even though the harm that gendered disinformation produces does not depend on whether this content was shared with …

And the final speaker in this final paper session at the AoIR 2025 conference is my QUT colleague Kate O’Connor-Farfan, who focusses on the 2022 Australian federal election. She begins by noting the tensions between scale and depth in social media analysis: computational methods often privilege scale over depth, and there are now attempts to overcome this with the use of LLMs.

Her work draws on data from the two leading candidates’ – Scott Morrison and Anthony Albanese – Facebook pages, from which she extracted the key narrative structures. An preliminary analysis of the key terms used by these political …

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:

The next speaker in this session at the AoIR 2025 conference is Lion Wedel, which also focusses on the role of TikTok during the 2025 German election. The project here was conducted in collaboration with several public service and commercial media organisations in Germany, and sought to examine what political content TikTok users in Germany actually encountered during the election campaign.

This relied crucially on data donations from TikTok users: it asked these users to download their TikTok data packages and donate these to the research project for aggregate analysis. Such projects often struggle with high drop-out rates; instead of …

The next session at the AoIR 2025 conference is on online election debates, and starts with the great Felix Victor Münch, focussing on the 2025 German federal election. His focus here is especially on the role of TikTok during that election – how is this affecting electoral campaigning and public debate? TikTok itself has recently acted against some problematic practices during a range of elections, in fact.

There is some correlation, in fact, between TikTok engagement with Left Party posts and voting intention for the party over the final stages of the election campaign, but such patterns should not be …
