The next ECREA 2024 session is also on polarisation, and I’m chairing as well as blogging it. We start with Petra de Place Bak, whose interest is in the cognitive preferences that make specific types of online content more salient and shareable. One aspect of this might be sentiment- and emotion-based biases.

Petra’s focus is on social media communication, which has to address the twin challenges of information abundance and attention scarcity; this is affected both by platform algorithms and users’ own cognitive preferences. Negative content biases can play a role especially in the latter, as can biases (both positive …

The post-lunch session on this first day of ECREA 2024 conference is on polarisation, and starts with Hendrik Meyer, whose interest is in the case of disruptive climate protests. Such protests, in Germany for instance by the Letzte Generation protest group, tend to attract controversial media coverage, and it may be such coverage rather than the protests themselves that drive polarisation dynamics.

Untangling the various factors influencing such dynamics is difficult, and this project examined both news media coverage and social media debates to determine patterns of both issue and group polarisation, in both the content of communication and the …

The next speaker in this rapid ECREA 2024 session is Christian Schwieter, whose focus is on the German news coverage of Telegram as a new and challenging social media platform. Telegram has become a hugely contested object in popular discourse; it has marketed itself as a strongly pro-democracy and pro-free speech platform, but is also accused of allowing hate speech and child abuse materials on its channels – notably Telegram founder Pavel Durov was recently arrested in France for this reason.

Telegram has also become a refuge for the deplatforming, and a space for alternative, conspiracist, and far-right groups. The …

I’m presenting a paper in this next session at the Social Media & Society 2024 conference, but we start with Chelsea Butkowski, whose interest is in emerging social media platforms. This is a tumultuous time for social media platforms, with considerable changes in ownership and structures and the emergence of new centralised as well as decentralised platforms and a great deal of speculation about the future of social media. In other words, there are plenty of sociotechnical imaginaries about social media at the moment, and perhaps social media are in a midlife crisis, or past their honeymoon phase.

How do …

The next speaker in this Social Media & Society 2024 session is Felipe Soares, whose focus is on asymmetric polarisation on Facebook in Brazil. He begins by noting the difficulty in defining polarisation, given the wide range of definitions available in the literature, and points to our work at QUT in developing the concept of destructive polarisation as a way to determine whether the polarisation that we might observe in any given context is in fact a problem at all.

Further, polarisation is often observed to be asymmetric, with one side of politics considerably more extreme than the other. This …
