Psychology and Human Behavior


The use of psychological and social processes in System Dynamics models can lead to a deeper understanding of a problem’s causes, and can enhance theory and practice in psychology and other social and behavioral disciplines.


We support members through a variety of initiatives, including: networking, education (presentations, short courses), collaborative modeling projects, and manuscript consultation and review. In our SIG workshop. Modeling Psychological and Sociological Dynamics (see below), we discussed concerns, impacts, and benefits in using psychological and sociological variables (i.e., so-called soft variables or intangibles) in models. We also described a process for incorporating these variables in models, especially in defining psychological concepts, transforming them to measurable variables, and relating them to other variables. Please email ( us with any questions or requests for support.


David Lounsbury ( and Pascal J. Gambardella (, co-chairs.


Our members are diverse, with training and expertise in social and behavioral science, mathematics, physics, business management, public health, public relations and marketing, as well psychology.
