New joint paper that only took us 3+years to get published! This inferrs the cognitive model of agents from data.
Batzke, et al. 2025. From cognitive coherence to political polarization: A data-driven agent-based model of belief change. doi.org/10.1111/pops...

"Consipracy theory" is a bit of a misnomer. What seems to characterise anti-vaxx, JFK shooting etc. is the asymettry to evaluation as noted above - nit picking contrary evidence accenting evidence for unquestioningly. Of course the ultimate denial of contrary evidence might be "its a conspiracy"

Though the gap between prediction rhetoric and achievment is widespread in science - serious and otherwise.

promiscuous associativity? This has the advantage of sounding clumsy and so might be taken up by philosophers ;-)

Maybe not a "pangloss journal"... but "Pangloss Reports" probably has a future 😉

Mind you, simplistic discussion of the economy is endemic among politicians - rather like arguing over how to fix a complicated engine by pressing the brake or the accelerator :-/

He got there, finally with health care... ‘Nobody knew health care could be so complicated’. He just needs some time to learn via trial and error.

With an increasingly turbulent society, the demand for social scientists who are capable of understanding and analysing what is happening using computational methods is rising. New free online course on polarisation! Good tonic for the times. Available to all. www.youtube.com/watch?v=6vmV...

OK, but the categorisation by YouGov might be who they last voted for and their opinion based on the current policies/rhetoric. That is reasonable

Modelling Deep Structural Change in Agent-Based Social 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 – 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 of randomness" by Peter Steiglechner and Marijn Keijzer on why testing your model with randomness is vital. #RofASSS #ABM #noise #randomness #robustness #socialsimulation #taxonomy #simulation #science #method #agent-based
Make some noise! Why agent-based modelers should embrace the power of randomness
By Peter Steiglechner1, Marijn Keijzer2 1 Complexity Science Hub, Austria; [email protected] Institute for Advanced Study in Toulouse, France Abstract ‘Noisy’ 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
