So, this is how things look when a society reached a tipping point from which there is no easy way out, and those in power continue to reinforce their position. They must be stripped of the levers that got them there, and everywhere else we have to pay close attention to prevent it from happening.

[New WP] With the closure of major social media APIs and the new data access mandates under DSA, we enter what we call the "post-post-API" era. But have researchers obtained the data they need? Our recent survey (180) + interview (19) study suggests a stark reality. 🔗 arxiv.org/abs/2505.09877 1/3

We’ve been working on this for a while and it’s great to see it live. Despite a lot of effort into understanding the impact of social media, consensus and effective policy seem elusive or insufficient. We try to to breakdown why that may be occuring and what a path forward might look like.

Reading the news, it feels like the pressures of the attention economy to simplify everything are gradually eroding our collective ability to deal with complex issues, and populists are benefiting from this. But the world is complicated and often unintuitive, and we need expertise to disentangle it.
