It's cool how aviation technology changed the topology of such networks.

This was such a fun paper to write! The development leading up to today’s social/behavioral science with AI agents. The history itself is a roller-coaster ride connecting many of the big themes of 20/21 century human-centric science.

The book is, of course, a classic in the pre-network-science complexity science literature. But I, for one, forgot that it also contains networks.

Duncan Watts makes the very apt point that we should aim for CSS that both predicts and explains. Here is one of the few Q4 papers (more behavioral than social though): www.science.org/doi/10.1126/...

Why do we intuit that theories that can be expressed by symmetric diagrams are more credible than others?
I wrote a blog post about that recently petterhol.me/2025/05/07/s... and just now found this great example from doi.org/10.1509/jm.7...
