The next speaker at the P³: Power, Propaganda, Polarisation ICA 2024 postconference is Heesoo Jang, whose interest is in the potential biases in Large Language Models. In the United States, a majority of Republican nominees for office in the last mid-term elections denied or questioned the 2020 presidential election results, and in Brazil similar election denialist groups have emerged. This is worsened by political attacks on press freedoms in these and other countries; globally, the challenges to democracies by the rise of far-right authoritarianism are growing. But most existing theories and concepts still focus on ‘stable’ democracies, wherever we might still be able to find them. Out approaches now need to centre normative democratic commitments.

The post-lunch session at the P³: Power, Propaganda, Polarisation ICA 2024 postconference starts with my excellent QUT colleague Tariq Choucair, whose interest is in measuring polarising discourses during election campaigns. Tariq and the team have developed a method to measure polarisation at the level of specific discourses: it is rooted in core principles and operationalised approaches that are adaptable to other contexts. Measuring polarisation at the discourse level is important; so far, so much of the work on polarisation has been done using surveys on self-reported political positioning or feelings towards leaders or parties, or has drawn on voting patterns in parliaments – but in recent years there has been a growth in attention to polarising rhetoric.

The next speaker at the P³: Power, Propaganda, Polarisation ICA 2024 postconference is the fabulous Jing Zeng, whose focus is on Trumpism in the online Sinosphere. There was a lot of public animosity between presidents Trump and Xi during Trump’s term in office, but there also appears to be a surprising amount of support for Trump both within China as well as in the Chinese diaspora around the world. Chinese-Americans were one of the groups of Asian-Americans with the greatest amount of support for Trump, in fact.

The final P³: Power, Propaganda, Polarisation ICA 2024 postconference session for today starts with Susan Grantham, whose focus is on the political uses of TikTok. Here, she is focussing especially on the use of the platform by individual politicians in the last Queensland election – which continued even though there were increasing moves to ban the platform in Australia, especially by political actors.

The next speaker in this ICA 2024 conference session is the great Mathias Felipe de Lima Santos, whose interest is in visual political communication across Facebook, Instagram, and Twitter in Brazil in the 2018 and 2022 presidential elections. Visual affordances are critically important in political campaigning, and such affordances continue to change; this works differently across different platforms, and cross-platform and/or multi-platform studies are therefore also critically important.

The final presenter in this session at the ICA 2024 conference is the excellent Hedwig Tønnesen, whose interest is in the strategies of political actors on three social media platforms. Social media are now widely used by such actors, of course, but have not necessarily delivered the wider democratic potential that some had seen in them; more often, they are simply used by parties to create engagement and mobilisation, or disseminate information and political advertising.

The next speaker in this ICA 2024 conference session is Francesco Bailo, whose focus is on the Italian Five Star Movement, or M5S. This was a disruptive political movement launched by comedian Beppe Grillo, and this study examined its activities across five platforms: Grillo’s blog, Meetup.com, the M5S Forum, Facebook, and the movement’s e-voting platform which was used to select electoral candidates. The focus here is on 2012 primary elections in the party.

The second presenter in this ICA 2024 conference session is Andreas Widholm, whose interest is in the use of TikTok by right-wing users in Sweden. There has been substantial coverage of a scandal in Sweden during the recent EU elections that centred on the communication strategies of the far-right Sweden Democrats’ troll factory on social media, and while this was uncovered after the present study concluded, the concerns about a right-wing wave on TikTok already existed and motivated this work.

The final speaker in this ICA 2024 conference session is David Coppini, whose interest is in news consumption and affective polarisation in the Italian context. Italy has a polarised pluralistic media system: the multi-party political system, comprised of three key blocs, is mirrored to some extent by an aligned polarised media system, but there is also a group of broadly neutral news organisations.
