The final speaker in this AoIR 2019 session is QUT DMRC PhD graduate Dr. Jing Zeng, whose focus is on the automated dissemination of conspiracy theories on Twitter – including suggestions that celebrities like Justin Bieber, industry leaders like Mark Zuckerberg, and royals are actually shape-shifting lizards; that planes spread mind-controlling chemtrails; that the Earth is flat; or that the California wildfires were started by a new energy weapon created by the U.S. government.

The final day at AoIR 2019 begins for me with a panel on social media bots, and the first speakers are Felix Münch and Ben Thies who present a paper that I have also contributed to; the slides are below. Social bots have become quite prominent in media coverage of social media in recent times, with particular focus on platforms like Twitter, but it is difficult to assess just how prevalent they are on such platforms, partly also because it is difficult to get a sense of the make-up of larger social media populations.

Filter bubbles and echo chambers have become very widely accepted concepts – so much so that even Barack Obama referenced the filter bubble idea in is farewell speech as President. They’re now frequently used to claim that our current media environments – and in particular social media platforms such as Facebook or Twitter – have affected public debate and led to the rise of hyperpartisan propagandists on the extreme fringes of politics, by enabling people to filter out anything that doesn’t agree with their ideological position.

But these metaphors are built on very flimsy foundations, and it’s high time that we examined the actual evidence for their existence with a critical eye. That’s what my book Are Filter Bubbles Real? sets out to do. There are several recent studies that claim to have identified filter bubbles and echo chambers in search results and social media discussions, yet there are just as many that find no evidence or report contradictory results, so what’s really going on here? Is the impact of these phenomena on public opinion really as significant as common sense seems to suggest?

As it turns out, neither concept is particularly well-defined, and even the authors who first introduced these metaphors to media and communication studies rarely ventured far beyond anecdote and supposition. In the book, I introduce more rigorous definitions, and re-evaluate some of the key research findings of recent studies against these new criteria – and as it turns out, most claims about echo chambers and filter bubbles and their negative impacts on society are significantly overblown. These concepts are very suggestive metaphors, but ultimately they’re myths.

Well, it’s mid-year and I’m back from a series of conferences in Europe and elsewhere, so this seems like a good time to take stock and round up some recent publications that may have slipped through the net.

Gatewatching and News Curation

But let’s begin with a reminder that my book Gatewatching and News Curation: Journalism, Social Media, and the Public Sphere was published by Peter Lang in 2018 and is now available from Amazon and other book stores. The book is the sequel (not a second edition) to Gatewatching: Collaborative Online News Production (2005), and updates the story of journalism’s transformation in the wake of sociotechnological transformations resulting from the rise of blogs, citizen journalism, and contemporary social media to the present day.

The focus here is especially on the way that gatewatching and newssharing practices on social media platforms such as Twitter and Facebook have changed audience activities around both breaking news stories and habitual news engagement, on the attempts by the journalism industry and by individual newsworkers to address and accommodate such changes, and on the implications this has for democracy and the public sphere as such.

Are Filter Bubbles Real?

My second new book, Are Filter Bubbles Real?, is something of an unexpected companion piece to Gatewatching and News Curation, and was published by Polity Books in 2019; it’s also available from Amazon, of course. As I wrote Gatewatching and News Curation, it became increasingly clear how much we are hampered, misled, and distracted from more important questions by the metaphors of echo chambers and filter bubbles that are no longer fit for purpose, and probably never were. From my conversations at the many conferences, I know that many of my colleagues feel the same.

In the book, I offer a critical evaluation of the evidence for and against echo chambers and filter bubbles. If, like me, you’re fed up with these vague concepts, based on little more evidence than hunches and anecdotes, this book is for you; if you think that there’s still some value in using them, I hope I am at least able to introduce some more specific definitions and empirical rigour into the debate. In either case, perhaps I will convince you that the debate about these information cocoons distracts us from more critical questions at present.
