Is social media dying? How much has Twitter changed as it became X? Which party now dominates the conversation?
Using nationally representative ANES data from 2020 & 2024, I map how the U.S. social media landscape has transformed.
Here are the key take-aways 🧵

Macron remarks are notable- some quotes: "We have been incredibly naive in entrusting our democratic space to social networks that are controlled either by large American entrepreneurs or large Chinese companies, whose interests are not at all the survival or proper functioning of our democracies."

In the literature, there are two competing explanations for "echo chambers":
1️⃣ Algorithms curate what we see (“filter bubbles”)
2️⃣ People choose like-minded peers (“selective exposure”)
Our new study suggests something surprising:
both explanations might be wrong. 🧵

Ever since I started thinking seriously about AI value alignment in 2016-7, I've been frustrated by the inadequacy of utility+RL theory to account for the richness of human values.
Glad to be part of a larger team now moving beyond those thin theories towards thicker ones.

Often our tech policy interventions operate from linear, top-down assumptions that don't account for the complexity they seek to govern.
To dig into this I'm co-organizing a workshop at ACM CI 2025 with Jason Burton, Joe Bak-Coleman, + Naomi Shiffman. You should come!

You might have heard of the "Habermas Machine", an AI-human pipeline that is really good at finding common ground between ideologically diverse groups, at least in lab settings.
But can this kind of approach help in real world conflicts?
