Modelling Deep Structural Change in Agent-Based Socialย Simulation By Thorid Wagenblast1, Nicholas Roxburgh2 and Alessandro Taberna3 1 Delft University of Technology, 0009-0003-5324-37782 The James Hutton Institute, 0000-0002-7821-18313 CMCC Foundation - Euro-Mediterranean Center on Climate Change, RFF-CMCC European Institute on Economics and the Environment, 0000-0002-0207-4148 Introduction Most agent-based models (ABMs) are designed around the assumption of a broadly stable system architecture. Whether exploring emergent dynamics or testing the effects of external interventions or stressors, such models typically operate with a fixed ontology โ€“ predefined agent types, attribute classes, behavioural repertoires, processes, and social and institutional structures.

Sorry, what has considering competence have to do with registering failed predictions? Are you thinking about a particular incident here?

Make some noise! Why agent-based modelers should embrace the power ofย randomness By Peter Steiglechner1, Marijn Keijzer2 1 Complexity Science Hub, Austria; steiglechner@csh.ac.at2 Institute for Advanced Study in Toulouse, France Abstract โ€˜Noisyโ€™ behavior, belief updating, or decision-making is universally observed, yet typically treated superficially or not even accounted for at all by social simulation modelers. Here, we show how noise can affect model dynamics and outcomes, argue why injecting noise should become a central part of model analyses, and how it can help our understanding of (our mathematical models for) social behavior.

Surely, we are already post-scarcity in developed countries. This is what it is like... we find other things to worry about and compete for (e.g. status)

As grant money starts drying up, it's more important than ever not to waste it on paying publishers' open access "article processing fees" when we can host PDFs for free. Tom Morgan and I wrote a paper on this, forthcoming at Science and Public Policy. Accepted draft here: osf.io/preprints/os...

I had a (deliberately funny) acknowledgement from a colleague on the lines of "we wish to thank... for their helpful comments and guidance. Needless to say none of these are responsible for any mistakes in the paper. I would also like to thank Bruce Edmonds" :-D

Nigel Gilbert By Corinna Elsenbroich &amp; Petra Ahrweiler The first piece on winners of the European Social Simulation Association's Rosaria Conte Outstanding Contribution Award for Social Simulation. โ€œGilbert, a former sociologist of science, has been one of the chief links in Britain between computer scientists and sociologists of scienceโ€ Nigel has always been and still is a sociologist - not only of science, but also of technology, innovation, methods and many other subfields of sociology with important contributions in theory, empirical research and sociological methods.

Just as the X account "in mice" added these words to the ends of titles that would otherwise sound more impressive and generally applicable than they are, I have launched an account @in-a-model.bsky.social to point out the same about papers whose conclusions sound as if about reality but are not.

OpenSAFELY documentation

I was just on @BBCr4today talking about our OpenSAFELY platform, and how we protect the privacy of NHS GP records while supporting hundreds of researchers to do lifesaving work. You can see a 4 minute video explaining how the platform works here:

How bad does it have to get before other countries realise they have to resist the bullying of Mad King Trump (MKT) and his entourage? The actions and self-serving beliefs of the current US administration seem strangely similar to those of Colonial Britain (and other empires) in the past.
