The first copy of my new @princetonupress.bsky.social book has just arrived at the office. It explores death in all its forms, from cells to minds, machines, languages and information. A complexity/evolutionary perspective, from Frankenstein to neuroscience. Soon out: www.amazon.com/Endless-Endi...

We know how to successfully use tons of data to (often) end up making poor, noncredible causal estimates uninformative to neither policies nor theories. We know less abt how to successfully build theories that push social sciences forward (eg ABM failed, dynamical systems're too hard). Much needed!

The new website for the Complex Systems Lab www.complexsystemslab.org is now available and will soon be completed with all kinds of information and updates, links to our recent papers, book recommendations, videos and podcasts.

The inauguration was held in Norrköping on May 6, bringing together researchers and guests from Sweden and abroad. The centre will support international collaborations, lectures, visiting researchers, workshops, and more.

Sacamos libro nuevo, esta vez en el idioma en el que aprendí a leer, escrito con @jordipc.bsky.social, periodista de El País. Es un ejercicio de divulgación en el que intentamos acallar el ruido y entender mejor por qué las redes (y ahora la IA) cambian el mundo en el que vivimos. ¡Ojalá os guste!

Social contagion has many biological predicates. This one is adorable. When mom yawns, her in utero baby yawns. :-)

Se vuelve a escribir mucho sobre Habermas. Hace 20 años publiqué esto argumentando las debilidades de su teoría: 1) ¿Es la racionalidad comunicativa conceptualmente diferente de la estratégica? 2) ¿Es plausible como principio explicativo de la acción? 3) ¿Es normativamente más defendible?

Since the first International Workshop on Analytical Sociology in 2008, INAS is returning to Oxford. The 18th Annual INAS Conference will take place from 1 to 3 July 2026 at the University of Oxford, hosted by Nuffield College and the Department of Sociology. Submission deadline: 1 Feb 2026

The European Network for the Philosophy of the Social Sciences (ENPOSS) invites submissions to its 15th Conference at the University of Helsinki, 26-28 August 2026. blogs.helsinki.fi/enposshel/

I just finished a three-year term as an editor at an international relations journal. I began at the start of the LLM era but ended right in the middle of it. Our volume of submissions tripled and our desk reject rate rose to 75%. I have some thoughts. open.substack.com/pub/hegemon/...

Statistical Rethinking 2026 Lecture B01 Multilevel Models is online. This is the first lecture of the "experienced" section, in which we start with multilevel models and venture into vast covariance spaces. Full lecture list still here: github.com/rmcelreath/s...

We should no longer trust data collected on MTurk link.springer.com/article/10.3... My guess is that other online data is going to drop in quality due to LLMs. This is going to be an existential crisis for the behavioral sciences.

It's been three (!) years since I last posted something on my blog, but you still gotta love cells, as they say... so here's a little piece discussing philosopher Talbot Brewer's talk/essay "What Good Are the Humanities?" lovecells.wordpress.com/2025/11/25/w... #philsky 💙📚

I was going to ask if someone knows of a comprehensive archive of US state policies that changed over the last 50 years. But then I remembered there's this: ippsr.msu.edu/public-polic... So now I'm posting it here for everyone's benefit instead

New paper with @jordantkemp.bsky.social and Luis Bettencourt is now on arXiv: “Spatial Selection and the Multiscale Dynamics of Urban Change”. We use the Price equation and Chicago data to show how fine-scale spatial sorting shapes macro growth trends. Read it here: arxiv.org/pdf/2511.06165

For us, this journey toward explaining *surprising macro outcomes* took many years. Grateful to my amazing co-authors, @martinarvidsson.bsky.social and Peter Hedström, and to all the reviewers who supported us along the way 🚀Out now: sociologicalscience.com/articles-v12...
