Complex Systems: Underlying Structures and a Unifying Principle
Exploring multiple simulations, students can
readily see that diverse systems exhibit similar
behavior. This is because they all oscillate, and
most oscillating systems – whether simple or
complex ‐‐ feature an underlying stock‐and flow
model with a balancing feedback loop
that connects the two main levels of the
Once students can identify oscillating behavior in systems from diverse contexts (physics, biology, social science, for example), and they recognize the common underlying structure, they should be able to extrapolate and apply their learning to better understand other complex systems they will encounter throughout their lives. They will hopefully be more keenly aware of and able to adapt to the cyclical nature of employment, finance and economics, and real estate, as examples.
Central to understanding complex systems is the premise that each system oscillates because of the inherent nature of its structure – not because of some outside force that acts on the system to cause the oscillation. This is particularly important when correcting or managing an undesirable behavior pattern. The remedy needs to be focused on changing the system structure. It is not a matter of pushing blame outward. The cause of the problem, and the solution to the problem, is within the system.
