New study examines 20+ years of armed conflict data across Africa. Researchers @kushwaha.bsky.social and @spintheory.bsky.social identify three conflict archetypes, but also show that classification does not necessarily help to predict the severity of conflicts.

A wintry day for complex systems!
People are often using AI to increase the seeming complexity of minimal ideas, where I find I spend most of my time taking highly complex ideas and compressing them as much as possible into minimal descriptions. Can AI do that? I would say not.

It’s times like these that remind me of Asimov’s Mule. And an interesting question about how far we can go beyond probabilities in looking ahead with social behavior.

2026년 가을부터 서울대학교 물리학과에 조교수로 합류하게 되어 매우 기쁘게 알립니다!
저에게는 새로운 장이 될 것이며, 학과에서 이미 진행되고 있는 놀라운 연구에 새롭고 복합적이며 다양한 기여를 더하게 될 것입니다.
마지막으로, 이러한 혼란스러운 시기에 민주주의와 법치주의를 수호하는 젊지만 활기찬 문화를 포용하는 곳으로 가게 된다는 것을 말할 수 있어 안도감을 느낍니다.
새해를 앞두고 미리 건배합니다! 🥂

Finally got around to read Darwin. The clarity of thought is wholly impressive and still compelling today.
Also very quotable and perhaps one of the reasons this work became such a recurrent tome.

This is nuts
“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

A fun read about group selection on culture, not genes 🧪
What changes when humans change: individuals with genes, or groups with culture?
In this month's Q&A, I talk with @twaring.bsky.social about his argument that humans are going through an evolutionary transition: groups are the new individual, and culture is the new genome. 🧪

Last month's Q&A with @spintheory.bsky.social dug into the ~physics~ of polarization in the US Senate and what it has to do with the simple neural network models that sparked the AI boom:
Politicians talk big. But what if (with a bit of physics) you could let their votes speak for themselves?
In this Q&A, I chat with @spintheory.bsky.social about what his mathematical maps of US Senate politics reveal about polarization — with a surprising link to the physics foundations of AI 🧪⚛️
