Pleased to share our new paper forthcoming in @icwsm.bsky.social! We introduce a novel framework to measure value expressions in social media posts at scale, leveraging personalization to handle the inherent subjectivity of human values. arxiv.org/abs/2511.08453

Our new CHI paper raises two connected ideas: (1) we can’t—and shouldn’t expect to—agree on all accounts of harm, which makes universal moderation inherently limited; and (2) instead of suppressing the content that harms a given user, we can transform it in a personalized way to preserve its value.

Our new article in @science.org enables social media reranking outside of platforms' walled gardens. We add an LLM-powered reranking of highly polarizing political content into N=1256 participants' feeds. Downranking cools tensions with the opposite party—but upranking inflames them.

New paper: Do social media algorithms shape affective polarization? We ran a field experiment on X/Twitter (N=1,256) using LLMs to rerank content in real-time, adjusting exposure to polarizing posts. Result: Algorithmic ranking impacts feelings toward the political outgroup! 🧵⬇️

🚨 Paper alert!🚨 We show how enabling users to moderate misinformation can be deployed everywhere on the web, in a platform-agnostic manner and without support from the social platforms or individual web sites arxiv.org/pdf/2403.114... #CHI24 With @karger.bsky.social 🧵
