The final speaker in this AANZCA 2024 conference session is Cameron McTernan, whose interest is in the sharing of Australian news on Facebook, especially by politicians. This can be understood through the lens of agenda-setting theory: news media content plays a crucial role in shaping what public issues audiences learn about, and politicians’ sharing of news media content seeks to channel and affect these processes. (There are also questions about the extent of such agenda-setting power.)

Cameron’s work focusses on Facebook, which remains a major and influential social media platform in Australia, with the vast majority of federal politicians active …

I presented in and chaired the Saturday morning session at the AoIR 2024 conference, which was on polarisation in news publishing and engagement, so no liveblogging this time. However, here are the slides from the three presentations that our various teams and I were involved in.

We started with my QUT DMRC colleague Laura Vodden, who discussed our plans for manual and automated content coding of news content for indicators of polarisation, and especially highlighted the surprising difficulties in getting access to quality and comprehensive news content data:

I …

The next speaker in this AoIR 2024 conference session is Richard Rogers, whose interest is in the concept of ‘coordinated inauthentic behaviour’ on Facebook. The term was introduced by Facebook’s Head of Cybersecurity Policy Nathaniel Gleicher in 2018, and has evolved substantially since then: from a generic definition of groups of pages or people working together to mislead others it was sharpened to a more narrow focus on the spread of ‘fake news’ for strategic purposes.

Richard illustrates this through an analysis (using Fabio Giglietto’s CooRNet tool) of coordinated activity on Facebook, and asks how Facebook’s redefinition of CIB might …

The next speaker in this AoIR 2024 conference session is Bruns Paroni, whose focus is on information campaigns on social media in post-Bolsonaro Brazil. Her work builds on our QUT research into destructive political polarisation, which amongst others identifies a breakdown of communication as a symptom of such destructive polarisation. Such breakdown might manifest as an absence of communication between opposing sides, and this is difficult to identify empirically if all we have is trace data about active communication processes.

This project focusses on comments, ‘love’ and ‘angry’ reactions, and shares on Facebook as indicators of affective polarisation on …

The final speaker in this AoIR 2024 conference session is Alma Kalisky, whose focus is on ‘flat earther’ conspiracist communities. Overall, conspiracist beliefs can have significant negative consequences at the personal, social, and societal level, but also provide a ground for community formation and social connection; at the individual and communal level, we must better understand what attracts people to these conspiracy communities.

Conspiracy believers often come from low socioeconomic backgrounds, have low interpersonal and political trust, and are often perceived as paranoid and dangerous; the emotional belonging that they experience is much less understood: conspiracy groups are communities for …

The final speaker in this AoIR 2024 conference session is the brilliant Jenny Stromer-Galley, whose focus is on the fundamental changes to the abortion debate in the United States since the current Supreme Court overturned the Roe v Wade ruling. Abortion has been a highly polarising issue in the US ever since women’s reproductive rights fell under legal jurisdiction in the 1800s, of course, and is tangled up with American nation-building mythologies.

Ever since the Roe v Wade decision in 1973, there has been a consistent effort to push back against its consequences, especially from the conservative right; this is …

Up next in this AoIR 2024 conference panel is my QUT colleague Daniel Whelan-Shamy, with whom I’ll present our paper on polarisation on Indigenous debates in Australia and Aotearoa New Zealand. In both countries there is a long and complex history of colonial oppression towards their respective Indigenous peoples. In Australia, the 2023 Voice to Parliament referendum sought to remedy this through the constitutional recognition of Indigenous peoples, while in New Zealand the Treaty of Waitangi was signed as early as 1840 and gradually led to greater recognition and rights for Māori groups. Our work examines the patterns of potentially …

The next speaker in this AoIR 2024 conference session is Luigi Arminio, whose interest is in the sociolinguistic patterns of polarisation on climate change on Facebook (this approach carries on from the previous presentation). Such patterns may also represent socioeconomic differences: people with lower socioeconomic status tend to be more open to climate change-denialist rhetoric, and such groups also differ from others in their overall communication styles. Can such differences be identified in climate discourse, marking the proponents and opponents of climate activism? Do they influence audience responses?

The project compiled some 10,000 posts from 250 public pro- and anti-climate …
