The world is in a “wave of autocratization.” Yet, recent events in Brazil, the Maldives, and Zambia demonstrate that autocratization can be halted and reversed. This article introduces “U-Turn” as ...

🚨 Excited to share a new paper 📃, years in the making, with Zach Wood.
We propose that human evolution is characterized as an Evolutionary Transition in Inheritance and Individuality (ETII).

What do Pac-Man, Space Invaders, and Mortal Kombat have to teach us about #cultural #evolution? As a social-technological phenomenon, #arcade game genres evolved like cultural species—some diversified, while others became "living fossils." 🕹️🧪 👉 doi.org/10.1017/ehs....

I have always loved linguistics, coming from Baltimore. This is awesome. I follow a bunch of linguistics and language people on TikTok, but my children have been watching it with me off and on and well, things have gotten a bit weird for me there.

Which Kind of Science Reform
What hope is there for science reform, if we can't agree on what to reform? Right now, principles are more important than practices.

Glad to see the old Broad Street Pump myth finally getting some public criticism. Terrible causal inference - I think we should stop teaching it altogether, or maybe teach it as an anti-model of good reasoning.

The reason Putin threw the richest man in Russia in prison and destroyed his fortune and redistributed his assets to his own cronies is so that the second richest man wouldn't have to choose.
