Data supplementary to the paper 'Modelling value change; An exploratory approach'

This model has been developed together with the publication ‘Modelling Value Change - An Exploratory Approach’<br>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.<br>We propose that a step forward can be made with the help of agent-based modelling (ABM). ABM can be used to investigate whether a simulation model based on a specific account of value change can reproduce relevant phenomena. To illustrate this approach, we 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.

本模型与学术论文《价值变迁建模——一种探索性路径》同步开发完成。

价值变迁与道德变迁日益成为哲学文献中的热点研究议题。目前学界已提出多种理论阐释框架，此类框架通常基于特定的理论与概念预设，且由于其依托的实证证据较为有限，其优劣性往往难以界定与比较。

我们认为，借助基于智能体的建模（Agent-based Modelling, ABM）技术，相关研究可取得进一步突破。该技术可用于验证：依托特定价值变迁阐释框架构建的仿真模型，能否复现相关研究现象。为阐释该研究路径，我们基于van de Poel与Kudina（2022）提出的实用主义价值变迁阐释框架构建了一款仿真模型。

我们证实，该模型可复现四类典型研究现象：1）价值的必然性与稳定性；2）不同社会对外界冲击的差异化响应模式；3）道德革命；4）锁定效应（lock-in）。
