"Urban Highways Are Barriers to Social Ties" out on PNAS!
The 1st large-scale measure of how highways weaken social connections between the communities they separate. This barrier effect is strong in the 50 largest US cities--especially for low-income Black communities.

What actually happens on social media when users get access to integrated AI?🤖

In our new preprint, we present a controlled experiment testing the impact of generative AI (4 treatments + control) on a social media platform, using a representative sample of nearly 700 U.S. participants.

Kicking off #ICWSM with the DETOX workshop and @maxfalken.bsky.social’s keynote on why the Web is not a set of siloed platforms and why we should not study it as such. Shows why deplatforming doesn’t work exactly as we expect and why large online platforms are plagued by affective polarization
