Evidence that multi-agent LLMs develop emergent coordination and specialized roles—especially with personas and "think about others" prompts. No free lunch tho: strong performance needs both alignment and complementarity arxiv.org/abs/2510.05174

📢 ✨ Symposium at #AOM2026: Augmenting Human Potential with Generative AI: Opportunities & Risks
Excited to be co-organizing this with @mattgroh!
Come join us to hear from the brilliant @alexolegimas @criedl @hamsabastani @ShiriM528 & Anita Woolley!
Our article "Complex Contagion in Social Networks: Causal Evidence from a Country-Scale Field Experiment” published in Sociological Science won the James Coleman Best Paper Award sociologicalscience.com/arti…

AI is not just a tool, it can reshape how people think, communicate, & connect.
New in #TOCHI: “Cognitive Spillover in Human-AI Teams” shows that AI use changes shared language & team cohesion.
Read:dl.acm.org/doi/abs/10.1145/3…
Authors: @criedl , Saiph Savage, Josie Zvelebilova
Think AI only affects the person using it? Our experiments show AI reshapes shared language, collective attention, mental models, AND social cohesion among human teammates. AI reshapes the cognitive ecology of teamwork
The complex contagion story, updated:
✅ Social reinforcement is real [1]
❌ You don't need hypergraphs to model it [1,2]
❌ You don't need simultaneous group interaction [1,2,3]
❌ It doesn't mean clustered networks win [3]

At #ICLR2026 Sci4DL (101B 10:00AM) I will be talking about @kevinlu4588's new work cracking open protein folding models to decode their internals.

Our lab is looking to fill a post-doc position to do research on collective intelligence in AI and human-AI systems. More details here christophriedl.net/jobs.html

2026 is a whirlwind year for AI.
Underlying it all: the greatest scientific mystery of our age. How does a neural network think?
I talked w @oliver_whang22 in NYTimes Magazine, on how AI interpretability is a tangle of structure waiting to be unraveled:
