Positive Feedback Loop
Updated 2026-08-13
INTRODUCTION
English translation pending.
CORE DEFINITION
A positive feedback loop returns part of a system's output as input in a direction that amplifies the original change, producing self-reinforcing growth or collapse. The core proposition is that the same structure produces both growth engines and collapse accelerators, so identifying the loop is more important than judging whether feedback sounds good. The key qualification is that amplification continues only until a limit is reached: resource constraints, saturation, or an opposing loop eventually arrest the exponential phase.
SCAFFOLDING EFFECT
Reduce cognitive load
- Loop identification: trace where an output returns to amplify its own input. - Direction read: determine whether the loop drives growth or collapse in the current conditions. - Lever decision: amplify with investment or damp it with friction, then set the boundary.
Anchor fast decisions
When a fraction of the output re-enters as input in the same direction, each cycle starts from a larger base, so change compounds rather than dissipating. Small initial differences therefore widen, which explains both winner-take-most markets and rapid panic. The exponential phase cannot continue indefinitely, because the reinforcing loop eventually meets a constraint that caps it.
