Positive feedback
A feedback relation in which the returned effect reinforces rather than counteracts a change in the relevant variable; the sign, loop gain, delay and limiting conditions must be specified.

Summary
Positive feedback reinforces change. It can create growth, escalation, tipping, latching, path dependence or oscillation. What stops the process is usually found in constraints, saturation, resource limits or another balancing loop.
Implications for practice
Reinforcing loops explain why small differences can become large and why systems can move rapidly away from an apparently stable condition. They are central to contagion, polarisation, bubbles, collapse, learning and mobilisation, but are not inherently beneficial or harmful.
Key distinctions
- positive sign vs positive value
- reinforcing loop vs exponential growth without limit
- amplification vs simple correlation
- loop polarity vs outcome desirability
Historical development
- early regenerative circuits predate the cybernetic synthesis
- mid-century control and cybernetics established positive and negative loop language
- system dynamics popularised reinforcing loop notation
Ideas it depends on
- feedback loop
- returned effect aligned with the direction of change
- loop gain and delay
- limiting conditions
Further developments
- tipping and lock-in
- escalation and vicious or virtuous circles
- oscillation and instability
- path-dependent growth
Connections to practice
- identify what reinforces what
- look for the limit that eventually stops growth
- do not label the loop virtuous or vicious before examining consequences
- test whether intervention also strengthens the loop
Common confusions
- positive means good
- reinforcing growth continues forever
- all positive feedback is instability
- praise is the technical meaning
Further checks
- historical lineage before Black
- system dynamics source locators
- nonlinear and tipping-point literature

First Circular Causality Principle offers a systems-law formulation of Positive feedback
Status: provisional · Relation: formalises
This is an interpretive conceptual crosswalk. It does not assert direct historical influence, formal equivalence or universal validity. The wording should be challenged or strengthened with page-level evidence.

Positive feedback amplifies variation within the project's account of Self-organisation
Status: accepted · Relation: explains
This is the feedback mechanism in Principia's project-authored account; it is not asserted as the only mechanism in every theory of self-organisation.

System Dynamics models reinforcing behaviour through Positive feedback
Status: provisional · Relation: uses
This is a provisional semantic or practice crosswalk. It does not establish historical influence, equivalence, efficacy or universal applicability. Item-level source review and curator acceptance are still required.

Claims and disputes
Positive and negative feedback name the sign and effect of a loop, not whether the result is morally or practically good or bad.
Claim status: corroborated. Review status: research pass needs editor.
