Exploring the Stepwise Process and Consequences of Identity Fusion in Different Groups: An ABM

In this paper we discuss the implementation and simulation of an agent-based model on identity fusion (IF), which is considered as a state in which agents have a single social identity from which they can satisfy their social needs. IF is the result of a dynamic step-by-step process with interaction between individual social needs and group characteristics. Consequently, fused agents have no alternative groups and can only satisfy their social needs by adapting to the behaviour of one single group. The simulation shows that long term fusion happens in groups requiring actions with high intensity, driven by agents with a high need for significance and belonging. Agents with different need urgency become locked-in in those groups and thus fused, without alternatives for need satisfaction.
