Denialist Themes in Reddit Discussions of the COP21 and COP25 Climate Summits

Politics | Polarisation | Social Media | Social Media Network Mapping | ICA 2026 | Liveblog |

The next paper in this session at the 2026 International Communication Association conference in Cape Town is presented on behalf of Chao Wu and Michelle Seelig, and focusses on public discussions of the COP21 (2016) and COP25 (2020) climate conferences on Reddit, with a particular focus on climate-contrarian comments.

Climate-contrarian claims were identified through the CARDS framework and its claims classifiers; this sorts claims into five broad categories of typical climate change-denialist rhetoric. The project then also conducted topic modelling, and clustered topics by their affinity with each other. This showed clear distinctions between the two events, with more issued-centred …

How ‘Structural Hole Spanners’ Contribute to Depolarisation

Politics | Polarisation | Social Media | Social Media Network Mapping | ICA 2026 | Liveblog |

As I wrap up my Mercator Fellowship at ZeMKI in Bremen, I’ve made a side trip to the 2026 International Communication Association conference in Cape Town, which starts for me with a session on the application of network analysis to polarised contexts. We start with Shengyi Gao, whose interest is in group polarisation. She notes the growing fragmentation of social media environments, which creates structural holes in such networks; some users are ‘structural hole spanners’, however, who bridge such gaps by their activities.

The focus here is on Weibo, and the network is constructed from post forwarding activities; the posts …

New Presentation Recordings: Public Sphere and Research Methods

Politics | Social Media | Publics | Practice Mapping | Social Media Network Mapping | Twitter | Dynamics of Partisanship and Polarisation in Online Public Debate (ARC Laureate Fellowship) | Publications |

My twelve weeks as a Mercator Fellow at the Zentrum für Medien-, Kommunikations- und Informationsforschung (ZeMKI) in Bremen are almost over already: I'll soon travel to Cape Town for the annual International Communication Association conference (more on this soon). I've had a great time here, and met some wonderful colleagues; the time has passed all too quickly.

My time in Bremen started with a presentation in the ComAI Lecture series at the Bremen Press Club, and I'm pleased to report that the video of the talk is now also available on the ZeMKI YouTube channel. The channel also has many …

Revisiting 'the' Public Sphere: The Podcast

Journalism | Social Media | Publics | Social Media Network Mapping | Dynamics of Partisanship and Polarisation in Online Public Debate (ARC Laureate Fellowship) |

A couple of months ago, I presented a critique of the concept of  'the' public sphere at the 2026 Digital Media Research Centre Summer School in Brisbane. Like the other talks in that segment of the Summer School programme, the team producing our DMRC podcast Read Them Sideways has now also published a recording of that talk for your listening pleasure, so here it is:

I think the podcast works fine by itself; since some of the presentation was fairly visual, though, if you'd like to flick through the slides while you listen I've embedded them below as well. And …

Upcoming Talks in Cologne and Bremen

Politics | Elections | Polarisation | Artificial Intelligence | Social Media | Publics | Practice Mapping | Social Media Network Mapping | Dynamics of Partisanship and Polarisation in Online Public Debate (ARC Laureate Fellowship) |

After the excitement of the Social Media Access Days at the German National Library last week I have now arrived at the Zentrum für Medien-, Kommunikations- und Informationsforschung (ZeMKI) at the University of Bremen, where I’ll spend the next couple of months as a Mercator Fellow. 

There will be a handful of side trips to other colleagues across Europe from here as well, though; in fact, I’ll begin the coming week with two days at GESIS, the Leibniz Institute for the Social Sciences, in Cologne, where I’ll also give a public lecture on our practice mapping approach as …

As I write this I'm just about to head off to Germany for a keynote at the Social Media Access Days at the German National Library, followed by a three-month stay as a Mercator Fellow at the fabulous Centre for Media, Communication, and Information Research (ZeMKI) at the University of Bremen, thanks to the Communicative AI Research Unit. That stay will also enable me to visit a number of other colleagues and collaborators along the way, including at GESIS in Köln, the University of Southern Denmark in Odense, the University of Münster, the Hans-Bredow-Institut in Hamburg, LMU München, and …

Revisiting 'the' Public Sphere, Again

Politics | Polarisation | Journalism | Industrial Journalism | Social Media | Social Media Network Mapping | ARC Future Fellowship | Dynamics of Partisanship and Polarisation in Online Public Debate (ARC Laureate Fellowship) | DMRCSS 2026 |

It's mid-February already, which means that here at the QUT Digital Media Research Centre we've just concluded another very engaging DMRC Summer School, with participants from around the world – many thanks to everyone who joined us for this.

One of the new segments in the programme this year was a session on 'Re-Thinking Media for the Platform Age', with several contributions from DMRC research leaders on current topics of interest. In my own talk for this, I revisited the idea of the public sphere once again, continuing a thought process that spans from my Information Policy article in …
