FEEDBACK / CYBERNETICS / HOMEOSTASIS
FEEDBACK / CYBERNETICS / HOMEOSTASIS
System notes
A controller must match the complexity of what it controls (requisite variety). Too simple fails; too complex wastes energy.
Negative feedback reduces error; positive feedback amplifies it. Runaway systems carry the seeds of their own end.
The universe corrects itself. Feedback is the engine of every stable thing you see.
Feedback is not the only pattern. A crystal has no feedback loop; it is stable by symmetry, not by control.
Not all feedback is virtuous. The pattern is neutral; the set point is where morality lives. Broken set points produce evil loops.

All living control is a loop (circular causality). Linear causality is a myth.

Climate feedback is contested: we do not know whether positive feedback (ice-albedo) or negative feedback (clouds, vegetation) will dominate.
