selfreinforcing

Selfreinforcing, or self-reinforcing, describes a process in which the output of a system feeds back as input in a way that strengthens the original effect. It is typically associated with positive feedback loops, where a small change causes effects that further amplify that change, potentially leading to rapid growth or escalation. The term is used across disciplines, including physics, biology, economics, sociology, and engineering. It is distinct from negative feedback, which tends to stabilize a system by reducing deviations.

Examples include: in engineering and electronics, regenerative feedback in amplifiers uses a portion of an output signal to reinforce itself; in economics and social systems, network effects and cumulative advantage create self-reinforcing growth in platforms or industries; compounding interest is a familiar financial form of self-reinforcement; in climate science, certain feedbacks (e.g., ice-albedo or greenhouse gas release) can amplify warming; in psychology, repeated behaviors or beliefs can become more entrenched through self-reinforcement.

Implications: self-reinforcing dynamics can accelerate change and improve efficiency when aligned with desirable outcomes, but they can also produce instability, volatility, or runaway processes if unchecked. Analysts study them with dynamical systems and feedback-loop models to identify thresholds, damping mechanisms, and control strategies. Understanding self-reinforcement helps in design of policies, technologies, and interventions that harness beneficial feedback while mitigating risks.
