Analysing the Dynamics of Norm Evolution Using Interval Type-2 Fuzzy Sets

Building on our previous work, we examine the effect of role specialisation on a society using a scenario from the area of comparative economics. In connection with this our central contribution is the use of Interval Type-2 Fuzzy Sets to model emerging normative understanding, which is represented using the concept of Dynamic Deontics. This integrated mechanism, along with a supporting visualisation component, permits a refined inspection of normative alignment on individual, group and society levels beyond mere quantitative analysis, thus offering a powerful extension to the institutional modeller´s toolbox.
