Towards a behavioural system dynamics: Exploring its scope and delineating its promise

Attempts to examine so-called ‘behavioural effects’ have reached into many different fields and are in full sway across OR. This paper considers whether this can be applied System Dynamics modelling a useful way. The idea is that humans frequently do not employ strict rationality their daily lives but make errors subject fallacies. shed light on the cognitive human interaction aspects of process outcomes modelling. first raises concerns about current state ‘Behavioural OR’ – BOR. To refocus underlying ideas it then returns Decision Theory roots, takes broader view using an illustration from history science builds work which proposed link (SD). core explores depth how behavioural apply SD. done examples dealing with complex systems ‘naïve’ versus ‘sophisticated’ way, mind map. It offers new detailed framework stages SD-based intervention, indicating presence effects providing fine-grained discussion those as they by proposing definition Dynamics’ (BehSD) terms its perspective phenomena, five new, constitutive axioms, potential for improving practice. closes reprising nature ‘BehSD’ sketching research adopts might go forward.
