Excited to share our new paper in Science: “Disorder-promoted stability.” It shows when heterogeneity across nodes—or interactions—can make complex networks more stable, with implications for ecosystems, power grids, materials, and beyond. science.org/doi/10.1126/scie…

Disorder-promoted stability

Previous studies of network dynamics have suggested that heterogeneity among nodes inhibits stability, which is at odds with the ubiquity of inherently heterogeneous natural and engineered systems....

Introducing: Time Machine Experiments 🚀 ⏳ in which participants 'travel' to the past, and interact with a mind from the year 1930 (simulated by an AI with knowledge cut-off). Preprint: arxiv.org/pdf/2609.15468 This is an example of what we recently called "Science Fiction Science" (Sci-Fi-Sci) Led by our @Max_Planck_CHM member @hiromu1996 @schimmelrob and Ezequiel Lopez-Lopez, together with @LevinBrinkmann Alejandro H. Artiles and Jean-Francois Bonnefon @azimshariff

New paper! When AI agents interact, the group can settle on outcomes none of its members would choose alone. And group size can determine which outcome wins. So a model that passes every test on its own can still go wrong at scale. pnas.org/doi/10.1073/pnas.25…

A beautiful example of an "optimal stopping problem" – Feynman's restaurant problem – with a great backstory behind it. This is a fun, well written article, and a fun math problem too. doi.org/10.1073/pnas.2509612…

Resolving Feynman’s restaurant problem reveals optimal solutions and human strategies | PNAS

In the 1970s, physicist Richard Feynman turned lunch with a friend into a math problem—how to optimize dish selection over multiple meals—but his h...

People help people with a reputation for helping others, but the same reciprocal norms do not extend to bots. An experimental study shows that people do not believe bots deserve help, even bots with a reputation for helping others. In PNAS Nexus: ow.ly/lW2c50W0U7k
Visual representation of network structures used in a chain reciprocity study, from the perspective of a participant in the A position. The baseline condition (left) shows four human figures, though two are bots, which participants were unaware of. In the hybrid condition (right), participants knew they were paired with two bots and one human, and the bots’ positions were disclosed. Both conditions involved identical underlying structures but differed in participants’ awareness of bots.
