By Nanda Wijermans and Bruce Edmonds “Greenwashing” is when claims are made by organisations (usually companies) to mislead “the public to believe that a company or other entity is doing more to pr…

When communities face their most pressing challenges—managing disaster risk, adapting to climate change, navigating energy transitions—solutions rarely...

The paper argues for, and discusses, the practice of “Strong Empirical Modelling”. This involves a shift in effort from the internals of a model towards how the model relates to observatio...

By Bruce Edmonds Introduction Machine-learning systems, including Large Language Models (LLMs), are algorithms trained on large datasets rather than something categorically different. Consequently,…

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.

By Peter Steiglechner1, Marijn Keijzer2 1 Complexity Science Hub, Austria; steiglechner@csh.ac.at2 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.

Dale Munday makes the case for participatory, adaptive, and evidence-based approaches to ensure new policies work when implemented

The most festive social simulation event of the year! For free!

We’re inviting contributions to a call for evidence to help shape the early phase of the commission. If you have insights, experiences, or ideas about how we can build more connected, cohesive and res...

By Corinna Elsenbroich & Petra Ahrweiler The first piece on winners of the European Social Simulation Association's Rosaria Conte Outstanding Contribution Award for Social Simulation. “Gilbert, a former sociologist of science, has been one of the chief links in Britain between computer scientists and sociologists of science” 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.

SSC 2025 will have presentations of full papers (long and short) as well as extended abstracts in special or general tracks, workshops, poster presentations, and an ESSA@Work session. ESSA@Work Stuck ...

Eighty years ago, the Allies rained down hell on the city, one of Germany’s cultural capitals

By Paola Galimberti The editorial note recently published in JASSS (Squazzoni 2025) focuses on the central role of peer review, an issue that has now become central to the debate on scholarly communication, research integrity and the role of artificial intelligence tools in research validation processes, particularly for journals owned by commercial publishers (e.g. Tennant et al. 2017). The fact that reciprocity between scientists is a core value of the academic system, in particular to ensure rigorous validation of scientific claims and self-correction mechanisms, is undeniable, and the call for a more responsible attitude on the part of scientists is therefore timely.
