If reinforcing loops only amplified, the world would consist entirely of explosions and collapses. It doesn't — because balancing loops exist.

A balancing loop is a feedback mechanism that resists change and pushes the system toward a goal or equilibrium.

The simplest example: a thermostat. You set the temperature to 20°C. The room cools to 18°C. The gap between the goal (20°C) and reality (18°C) triggers the heater. The room warms. When it reaches 20°C, the heater turns off. The room cools again. The cycle repeats.

The balancing loop is constantly monitoring the gap between the goal and the current state, and adjusting flows to close that gap.

Every thermostat, every budget controller, every immune response, every hunger signal, every market price correction — they're all balancing loops.
