Systems
Positive Feedback Loops
System dynamics where outputs amplify inputs, creating self-reinforcing cycles that can lead to rapid change, explosion, or collapse.
Biological Context
Fever increases metabolic rate which increases heat production. Predator-prey cycles can spiral to extinction. Population explosions show positive feedback. Biological systems typically include negative feedback to constrain positive loops.
Business Application
Network effects are positive feedback: more users attract more users. Viral growth, bank runs, and market bubbles all involve positive feedback. The challenge is igniting beneficial loops and dampening destructive ones.
