We built a new social media algorithm from the ground up that gives you full control. And we figured hey, while wer're doing that, let's design it to help people out with their conflicts. www.betterconflictbulletin.org/p/the-first-...

It really is a better algorithm -- not just controllable, but actually finds good stuff.

What could it mean for an AI to be "politically neutral”? And can we measure it? New paper + dataset. We propose a definition that applies to any type of conflict on any topic: a neutral response should maximize approval on both sides of an issue, while keeping that approval balanced. 1/🧵

🚨New preprint and our results are rather concerning.. We find the "boiling frog" equivalent of AI use. Using large-scale RCTs, we provide *casual* evidence that AI assistance reduces persistence and hurts independent performance. And these effects emerge after just 10–15 minutes of AI use! 1/

Game theory does not have a way to distinguish "conflict" from "competition." I think the difference is whether people are using destructive moves (e.g. murder) to win the game. Such moves are defections in the meta-game of peace and security.

Could social media make us less polarized instead of more? We tested 5 algorithms on 3 platforms with 10,000 people for 6 months during the 2024 election, and found that the answer is yes. 🧵

I'm pretty sure the CJEU in Russmedia just casually dismantled 80% of the DSA with one ill-considered judgment. As I read it, it substitutes in GDPR rules -- not notice and takedown rules -- for any platform where a user is likely to post content about people. 1/ curia.europa.eu/juris/docume...

AI presents a fundamental threat to our ability to use polls to assess public opinion. Bad actors who are able to infiltrate panels can flip close election polls for less than the cost of a Starbucks coffee. Models will also infer and confirm hypotheses in experiments. Current quality checks fail

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."

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.

🔔 (new paper!) 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?
A diagram of the process used in the paper that this thread announces. The effort consisted of four dialogue cycles with peacebuilders: three uninational dialogues cycles conducted respectively with
Israeli Jews, Palestinians from the West Bank and Gaza, and Palestinian citizens of Israel, followed by a final joint dialogue involving
all three groups. Each dialogue cycle involved a process to find common ground among participants followed by a deliberation on the
results of that process. The common ground process started with a collective dialogue, then bridging-based ranking was used to
identify common ground ’bridging statements’ that were distilled into articulate ’collective statements’ via LLM and reviewed by
human experts before being shared back with participants for a final vote.

Reframing the issues of governing social media. Human discourse is a social process that depends on three pillars: agency, mediation, & reputation. Without these three strong pillars, + middleware enabling open innovation and interoperation, social media will struggle to balance chaos and control.
