Negative feedback loops are a form of reciprocity

Evidence

Stable, balanced systems are typified by negative feedback loops, in which a change in one component incites an opposite change in another, so they balance each other out. When hunger causes increased eating, eating causes decreased hunger; satiety is possible. Negative feedback is a form of reciprocity, a coupling of forces that create balance and sustainability. — Robin Wall Kimmerer, Braiding Sweetgrass, 1119

Categorization

• DEEPTHINKING: The single most powerful hinge claim of the polyad: defining reciprocity itself in systems-science terms (‘coupling of forces that create balance’) — bridges Indigenous ethics and ecology as one principle.
• DEFINE: Redefines reciprocity as negative feedback — a definitional bridge usable across all four courses.
• ADDENDUM: Directly extends the Grafting & Growth essay’s argument that trees function as ecological infrastructure — here reciprocity is given a formal systems definition that deepens the metaphor of grafting as mutual coupling.
