Based on a dialogue on the System Dynamics mailing list regarding the current level of acceptance of System Dynamics after it has been promoted for over 70 years I dredged up the following set of influences as a thought exercise. This is an example of a Drifting Goals Archetype.

Australian health care challenges, inspired by Gene Bellinger's AI gemini causal loop modelling of US healthcare posted to substack in Jan2026

Simplified system dynamics model of the global carbon cycle. The model represents carbon exchange among four aggregated reservoirs: atmosphere, terrestrial biosphere, surface ocean, and deep ocean. Fossil fuel emissions enter the atmosphere as an external forcing, while internal flows redistribute carbon between the atmosphere, land, surface ocean, and deep ocean. The model is intended to explore transient behavior, natural carbon sinks, atmospheric carbon persistence, and the long-term regulating role of the ocean.

This is a stage-structured population growth model of the Loggerhead Turtle based on the model developed by Crouse et al. (1987).

A system dynamics model of Personal Tutor Ltd, an online tuition centre in Zambia. The model represents monthly student-lesson scheduling, student and teacher connectivity disruptions, outstanding lesson obligations, make-up lessons, and financial adjustments over a 12-month baseline period. It supports analysis of lesson completion, missed lessons, recovery capacity, and outstanding obligations under different operating conditions.
