The next session at the ICA 2024 conference is on polarisation, and starts with the great Helena Rauxloh. Her paper emerges from the POLTRACK project led by Lisa Merten, which builds on longitudinal Web tracking and survey data from some 4,000 participants in Germany. The key concept in this study is political efficacy, which is the feeling that political action has an impact on political processes. This divide into internal and external efficacy as experienced by individuals, and such efficacy mediates news exposure and political engagement. It is thus a precondition for political participation.

Another aspect to consider here is …

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. This also generates visibility and amplification for their content, as well as engagement metrics for the political actors themselves.

Such uses are also constrained by …

The next speaker in this ICA 2024 conference session is Mengyu Li, whose interest is in link-sharing patterns on Twitter and Reddit, here in the context of the abortion debate in the US following the Supreme Court’s abolition of Roe vs. Wade. Which information domains are critical in this context – health and welfare, civic and activism, political and legal, economic and employment information? How do social media platforms address these information needs? What primary sources are being shared here? What are the themes and strategies of such sharing?

This study gathered one year of data between March 2022 and …

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 focus here is on the visibility and associability affordances of these platforms; visibility enables users and their content to see and be seen within a social …

The Sunday at the ICA 2024 conference starts with a session on digital affordances of social media platforms, and begins with a paper by Christian Baden. Social media are many and diverse, and their affordances keep changing; this still needs to be better understood. Social movements are also many and diverse, which also means that the intersections between social media and social movements can be various, and the particular political intentions and communicative purposes of those movements need to be considered in this.

Social media affordances overall enable visibility, editability, persistence, and association – but what we need to move …

The final speaker in this ICA 2024 conference session is the great Damiano Spina, who begins by highlighting the current challenges to the global information environment. In the IPIE survey of disinformation experts, politicians, social media platforms, and governments were seen as the most problematic sources of mis- and disinformation.

Computational methods are critical to addressing these problems. They can assist in fact-checking by engaging in claim detection and assessing check-worthiness, supporting evidence retrieval, and enabling veracity and truthfulness classification. But they can also assist in the reporting and dissemination of fact-checks. This does not remove the role of the …

The next speaker in this ICA 2024 conference session is the excellent Giada Marino, presenting some of the work of the Vera.ai research project. Responding to the challenge of mis- and disinformation, the project focusses especially on the coordinated communication networks that share such content in order to influence and manipulate social media audiences, and has developed a content-agnostic tool that monitors the activities of identified problematic accounts.

This currently works with CrowdTangle data, and is therefore under threat from the impending closure of the CrowdTangle data. Monitoring lists of problematic accounts derived from Meta alerts, it gathers up to …

The next speaker in this session at the ICA 2024 conference is the wonderful Jessica Gabriele Walter, who shifts our attention to the dissemination of verified false content on Facebook in the EU (and UK). This seeks to examine also the patterns of engagement with such content (rather than mere posting), and to do so draws on the Facebook URL Shares dataset.

The URL Shares dataset covers all URLs shared on Facebook that were shared more than 100 times on the platform, and adds monthly exposure and engagement data for some 48 countries and broad age groups and gender categories …

The next session at the ICA 2024 conference starts with a paper that my QUT Digital Media Research Centre colleague Dan Angus and I are presenting, so I’ll blog Dan’s part and then leave it to our slides to explain my contribution. Our work is part of a large project that investigates the dissemination of problematic, ‘fake news’ content on social media platforms.

We approached this by constructing a masterlist of some 2,300 problematic information domains which have been identified in past research, with a focus mostly on the United States, and building a research stack around that seed list …

The next session at the ICA 2024 conference is the annual Steve Jones lecture, which this year is presented by my QUT colleague Jean Burgess and is on the impact of the newly emerging generative artificial intelligence technologies. This should not be confused with the substantial hype around artificial general intelligence, a technology which always seems to be just around the corner and has yet to actually eventuate.

Rather, this talk is about the more limited generative AI systems that appear to have invaded all sorts of projects, and seem to be universally indicated now by sparkle (✨) icons and …
