Uncovering simultaneous breakthroughs with a robust measure of disruptiveness An embedding-based disruption measure not only robustly captures disruptive works but also reveals simultaneous discoveries.

The Higgs mechanism was proposed in 1964 by three independent teams.

But here is the puzzle🤔: the "disruption index" says Higgs's paper is among the least disruptive ever.

So what is going on?

In our new paper, just out in #ScienceAdvances, we take up this puzzle: doi.org/10.1126/scia... 👇

🚨 New working paper 🚨

Can LLMs with reasoning + web search reliably fact-check political claims?

We evaluated 15 models from OpenAI, Google, Meta, and DeepSeek on 6,000+ PolitiFact claims (2007–2024).

Short answer: Not reliably—unless you give them curated evidence.

We’re recruiting PhD students at @uvadatascience.bsky.social, and I’m looking for students to join our group (Y Lab) next year!

My group works at the intersection of network science, machine learning, and interpretable AI.

We find that a post doesn't need to be toxic to attract toxic comments ☢️ Our Reddit data shows that 47% of non-toxic submissions still attract at least one toxic reply, while only 6% of toxic submissions do. The initial post's content, therefore, is a poor predictor of a comment section's health.

A simple solution, prioritizing only “the feel-good" content, is flawed, as it avoids important societal topics that are inherently negative and can devolve into toxic debates. After all, how often does thinking about wars, viruses, or economic policy put a smile on your face?

Modern social media is divisive, partly due to recommender algorithms that promote emotionally charged, negative content at the expense of thoughtful discourse. Researchers are exploring prosocial recommenders that foster positive outcomes, aiming for users to feel connected rather than angry 💡

New Directions in Social Algorithms Research on October 16-17, 2025 at Yale University As social media algorithms increasingly mediate social experiences, there has been a rapid increase in research on the effects of how these algorithms are configured, alternatives to engagement-centri...

📣 Yale workshop, Oct 16-17! 📣 How could/should content ranking work? What's new in content moderation? How can platforms promote civility? Hosted by Yale's Institute for Foundations of Data Science (FDS). Great speakers! Submit posters by 9/22! Spread the word! yalefds.swoogo.com/socialalgori...

Today (w/ @ox.ac.uk @stanford @MIT @LSE) we’re sharing the results of the largest AI persuasion experiments to date: 76k participants, 19  LLMs, 707 political issues.

We examine “levers” of AI persuasion: model scale, post-training, prompting, personalization, & more!

New preprint! 🚀 We looked into the rise of Bluesky and found that this platform is definitely sticking around 🚀
Huge kudos to my amazing co-authors for digging through nearly two years of all Bluesky data!
