Our Project
• Australian Laureate Fellowship (2022-27)
• Determining the Drivers and Dynamics of Partisanship and Polarisation in Online Public
Debate
• Digital Media Research Centre, Queensland University of Technology, Brisbane, Australia
• 4 postdocs, 4 + 4* PhD students, 1 data scientist
• Cross-national comparisons (intended: AU, US, UK, DE, DK, CH, probably + BR, PE, CA)
• Longitudinal analysis over the course of the project
* Starting in 2024 – interested? Get in touch! (a.bruns@qut.edu.au)

Forms of Polarisation
• Polarisation at what level?
• Issue-based: disagreements over specific policy settings
• Ideological: fundamental differences based on political belief systems
• Affective: political beliefs turned into deeply felt in-group / out-group identity
• Perceived: view of society, as based on personal views and media reporting
• Interpretive: reading of issues, events, and media coverage based on personal views
• (and more…)
• (chapter forthcoming in the Routledge Handbook of Political Campaigning)

Agonism? Polarisation? Dysfunction?
• How bad is it, exactly?
• All politics is polarised (just not to the point of dysfunction)
• Much (most?) politics is multipolar, not just left/right
• When does mild antagonism turn into destructive polarisation?
• We suggest five symptoms (Esau et al., 2023):
a) breakdown of communication;
b) discrediting and dismissing of information;
c) erasure of complexities;
d) exacerbated attention and space for extreme voices;
e) exclusion through emotions.

Our Approach
• Is there a robust empirical way to do this, beyond feelpinions?
• Plans:
• Full-text access to (online, text-based) news content across target countries
• Manual and computational analysis of:
• Topical focus and voices featured in coverage
• Language, tone, sentiment of coverage
• Framing of actors, issues, events in the news
• Also: experimenting with the use of AI (LLMs) in content coding
• Exploration of systematic divergences between news outlets

18. CRICOS No.00213J
Our Approach
• Can we capture news audience engagement patterns?
• Plans:
• Long-term generic news sharing data (for Twitter, Facebook; other platforms tbd)
• ATNIX, DETNIX, NOTNIX, FakeNIX
• Correlation with likely political positioning (e.g. MP-MPAS approach: Giglietto et al., 2019)
• Exploration of typical news sharing repertoires and their disjunctures
• Can we move beyond active sharing, and towards more passive encounters?
• Plus: potential use of primary and secondary (e.g. DNR) survey data

22. CRICOS No.00213J
Our Approach
• Case studies of major public debates, with cross-national comparisons where possible
• Plans:
• Long history of research into online public debates, especially on social media
• Issue mapping / controversy mapping approaches well established
• Extension from older platforms (Twitter, Facebook) to new spaces (Telegram, TikTok, …)
• and to cross-platform analysis approaches, tracing connections and flows
• Network, content, sentiment, timeseries analyses, …
• Also: public debates in per se apolitical ‘third spaces’ (Wright et al., 2016)

Our Approach
• Is it still possible to map underlying online social networks, even after the APIcalypse?
• Plans:
• Facebook, Twitter: no longer possible to replicate past studies (at least for now)
• Emerging methodologies for Telegram and other newer platforms
• Data donation-based research possible but necessarily very uneven
• But: feasibility substantially dependent on future developments in social media landscape
