Map reinforcing (R) and balancing (B) feedback loops between variables to see system behavior.
A system with many interacting parts that learn and adapt.
Many interacting parts producing emergent behavior nobody designed.
Single-loop fixes the action. Double-loop questions the goal or model that produced it.

The whole has properties that the individual parts do not.
Systems maintain stability by self-regulating around a setpoint.
Subjects often converge to neoclassical predictions only after many rounds of feedback — not on the first try.
