The first keynote at the iCS Symposium is by Alice E. Marwick, whose focus is on the motivations for sharing the various forms of content grouped under the problematic moniker of ‘fake news’. Her recent report with Rebecca Lewis on Media Manipulation and Disinformation Online has shown that such sharing can be highly effective: because so many of us are now sharing news and news-like information online, and because especially younger users and journalists are paying increasing attention to what is happening on social media, it is now possible for mis- and disinformation content to migrate from far-right, fringe spaces through mainstream social media sites and on to hyperpartisan far-right press sites and even the mainstream news media. One of the vectors for infiltrating the mainstream news in this process tends to be Fox News, unsurprisingly.

The first paper in the final session at AoIR 2018 today is SeongJae Min, who is interested in the role of algorithms in determining what we are exposed to on social media; the major finding from his research is that people’s choices matter at least as much as algorithmic shaping.

The final speaker in this Social Media & Society 2018 session is Andra Siibak, whose interest is in opinion polarisation on social media and the question of whether these constitute ‘echo chambers’ or ‘filter bubbles’. Individual abilities and digital literacies might affect the extent to which users find themselves in such environments, or are aware of them. Andra examined this in the context of an anti-immigration Facebook community in Estonia.

The next speaker in this session at ICA 2018 is Marco Toledo Bastos, whose interest is in the presence of echo chambers in the debate leading up to the Brexit vote. Echo chambers, especially on social media, have been blamed for the unexpected results of that referendum and a variety of other elections, but recent research has also challenged such perspectives.

The final speaker in our ICA 2018 panel is Neil Thurman. He notes that beyond the platform studies we must also look at the intersections between different social networks and platforms, and at the broader societal debate about echo chambers and filter bubbles. His work builds on the 2016 Reuters Institute Digital News Survey (covering 26 countries), and explores how aware and concerned users are of and about the algorithmic and editorial selection of the news content they engage with.

The next speaker in our ICA 2018 session is Bibi Reisdorf, who focusses on how people tailor their social network connections through friending, unfriending, and blocking. This again draws on the Quello Search Project study, a survey of 14,000 search users across seven nations.

The next paper in this ICA 2018 session is mine. The slides are below, and there’s also a full paper on this topic (from last year’s Future of Journalism conference):

The second ICA 2018 session this morning is the one I have a paper in as well – we’re discussing the (scant) empirical evidence for echo chambers and filter bubbles. We start, though, with a paper by Anja Bechmann that is working with a broad sample of newsfeed data from Danish Facebook users.
