A recent YouGov poll found 45% support for admitting no new migrants and requiring large numbers to leave - but a deeper look suggests that most of this group don't actually want to remove those who make up the bulk of migrants to the UK ๐Ÿงต/

Applebaum on Autocracy Anne Applebaum warns that Sudanโ€™s descent into chaos shows what happens when institutions failโ€”and why a free press is essential to prevent America from following the same path.

โ€œFor news organizations, the issue isnโ€™t responsibility, but survival. Autocratic leaders donโ€™t want evidence-based journalism of any kind to exist at all: They want to shape reality, to decide themselves what is true and false.โ€ โ€” @anneapplebaum.bsky.social

Interesting paper that can extend to digital technologies generally and concludes:
โ€œUnderstanding the consequences of actual AI for actual democracy, and figuring out how to steer toward the better rather than the worse outcomes, will require new kinds of cooperation than the ones we have today.โ€

AI and Democratic Publics

New paper in our AI & Dem Freedoms series: @himself.bsky.social and @hahrie.bsky.social argue that the existing paradigm of democracy driving scholarship about its relationship to #AI highlights the wrong questions, and that we should focus on enduring democratic publics and collective behavior.

This comment is the brief spiritual successor to our preprint (linked below) in which we argue much ado within debates over causal effects of social media stems from failing to account for the assumptions required by RCTs.

Whatโ€™s in a correlation? Correlation may not imply causation, but letโ€™s just ignore that for a second. Correlations are standardized effect size metrics and as such have some quirks by design. These are benign enough when you...

New blog post! Calculating a correlation is easy enough. But let's say you calculated two of them and they happen to differ. What follows from that? Turns out there are too many moving parts for an easy answer.

โ€ฆthis requires transparency, expertise and action by civil society and politics. There is no easy way out: if we donโ€™t properly understand the systems and co-shape them (with regulation or alternatives), others will do it to gain power. Just because things are moving fast we canโ€™t give that up.

I think we are walking into the same traps with AI as we did with social media: information technologies are making new areas and scales available, but they are not neutral but built by people and companies for certain goals and wonโ€™t just magically align with democratic values or well-being, โ€ฆ 1/2

Important longitudinal trends here, is this the direction we want to move?

I donโ€™t have the answer, but those results help us as a society to (finally) have debates about how the digital public sphere should work and start shaping it. Data like this is crucial to have an empirical foundation๐Ÿ‘‡

#ic2s2 getting started!
A grand hall for a grand opening.

Unsurprisingly LLMs make up their own strong topic among conference presentations. But amazing to see that CSS still maintains an identity and topical diversity beyond that!

Looking forward to #ic2s2 where I'll present some of our latest work from the @some4dem.bsky.social project:

I've been spending the summer taking stock of the growing, maturing field of qualitative computational methods (compu/qual? quali-quant?). This subfield is now a powerhouse, and I'll be sharing my reflections at #IC2S2 on the state of the field, ongoing (fierce!) debates, and possible futures?
