Benchmarks of LLM common sense overwhelmingly rely on correct labels to report an accuracy score. But what if your "ground truth" genuinely differs from mine? In a new @pnasnexus.org paper, @duncanjwatts.bsky.social, @whiting.me and I explore the implications of this intriguing question. 🧵⤵️

#CSSLab at Penn attended #NetSci2026 in Boston! A highlight was the keynote by Dr. Watts and Dr. Strogatz, who shared the stories and questions behind their work on small-world networks and its lasting impact on network science. We also enjoyed catching up with Dr. Barabási and Dr. Albert!

The first day of SICSS-Penn 2026 just recently concluded! We were honored to have @dhopkins1776.bsky.social deliver the opening remarks, and @dalbarra.bsky.social give the first lecture on AI and the psychology of persuasion.

Last week, a powerful coalition—Meta’s #AIforGood, #DirectRelief, #CrisisReady & the #CSSLab at Penn—gathered to explore how AI, open data & mobility insights can support emergency preparedness ahead of the 2026 FIFA World Cup. 🧵 #DisasterResponse #FIFA #WorldCup2026
