Special Issue

SIA and ABM - a special issue

The use of SIA in ABMs to understand or represent within and between-group dynamics is increasing. As the application domains are spread and the ways we formalise so diverse, we see a need for an overview, showcasing the diversity of SIA ABMs,  providing guidance for modelling SIA, etc.  This special issue in the Journal of Artificial Societies and Social Simulation (JASSS) will target exactly that...

Author submission guidelines

The authors of the special issue submit  themselves to JASSS (here) after receiving the green light from their editor. Make sure to mention in the last step of submission - ‘Message to the editor’ - that this is a contribution for the SIAM special issue: "Social Identity approach in agent-based modelling”. To your designated editor you send 2-3 review suggestions (incl. affiliation and email adresses). 

 Authors should follow the guidelines for submission from JASSS (link), this includes:

Author workshop 27 & 31 Jan 2022

To support the process of producing high-quality papers for this special issue, we will have an author workshop over 2 days of 27 & 31 Jan 2022. Each workshop day will have 4 authors presenting their work, after which they get feedback from a peer-based on an extended abstract and the presentation and a general Q&A.  

How to prepare? See Author workshop preparations and description.pdf

If you are modelling aspects of the social Identity approach (SIA) using ABM then this special issue may be for you!

Over the years, more and more modellers are (interested in) using aspects of the SIA to improve the realism of models of social and collective behaviour (see for example https://www.siam-network.online/). At the same time, many modellers face the challenge of modelling human behaviour and decision-making and/or making use of social/behavioural theory. A key challenge for designing an ABM is to represent human behaviour in a way that is psychologically plausible, i.e., how the relevant aspects of behaviour can be formalized using computer code. This choice of how to represent human behaviour in a model is critical, as subtly different assumptions here might result in very different model results (Dressler 2018, Wijermans 2020). The challenges we have when formalising human decision-making and behaviour, and implementing social/behavioural theory, is taken on for a family of theories (SIA) that offer high potential to develop context-sensitive decision-making.


The Social Identity Approach (SIA) reflects a family of theories that explain human behaviour and decision-making in its social context representing how people might decide what to do within a specific context and social-physical situation. SIA proposes that people derive a significant part of their self-concept from the social groups to which they belong. SIA posits that social identification with others, and the perception of people as fellow group members or outsiders, is a fundamental basis for collective behaviour, and investigates how and when individuals come to feel, think and act as group members rather than as unique individuals (Tajfel, 1978; Tajfel & Turner, 1979; Turner, Hogg, Oakes, Reicher & Wetherell, 1987). 

We are seeking articles for a special issue in the Journal of Artificial Societies and Social Simulation (JASSS) targeting agent-based social simulations that use SIA. With this special issue we aim to showcase a set of ABMs that actually formalise aspects of SIA. Our purpose is threefold:

We would like to invite you or anyone you know working with SIA and ABM to contribute to this special issue. We are looking for original work that makes a serious attempt to formalize SIA and integrate it into agent-based models. Justification for all SIA points & formalizations chosen and projects from interdisciplinary teams are especially welcome. To ensure a coherent set of high-quality papers and co-develop advances in the area, we plan to hold a workshop for authors to share their work in a way that allows them to profit from the expertise of all.
