This model was developed together with the publication ‘Modelling value change - An exploratory approach’.

Value change and moral change have increasingly become topics of interest in the philosophical literature. Several theoretical accounts have been proposed. Such accounts are usually based on certain theoretical and conceptual assumptions and their strengths and weaknesses are often hard to determine and compare, also because they are based on limited empirical evidence. We propose that a step forward can be made with the help of agent-based modelling (ABM). Using the model, we can investigate whether a simulation model based on a specific account of value change can reproduce relevant phenomena. We have built a model based on the pragmatist account of value change proposed in van de Poel and Kudina (2022). We show that this model can reproduce four relevant phenomena, namely 1) the inevitability and stability of values, 2) how different societies may react differently to external shocks, 3) moral revolutions, and 4) lock-in.
