Self-reinforcing or self-regulating cycles where a system's output affects its subsequent inputs, leading to either amplification or stabilization of effects over time.

Feedback Loops

Feedback loops are fundamental patterns in complex systems where the output of a process influences its future inputs, creating circular chains of cause and effect. These mechanisms are essential to understanding how systems maintain stability or undergo dramatic changes.

Core Types

Positive Feedback

Amplifies changes in a system
Creates exponential growth or decline
Examples include:

Negative Feedback

Dampens changes and promotes stability
Maintains equilibrium states
Common in:

Applications Across Domains

Natural Systems

Natural feedback loops are prevalent in Ecosystems, where predator-prey relationships, resource consumption, and population dynamics create intricate webs of feedback. The Carbon Cycle demonstrates how feedback loops operate on a planetary scale.

Social Systems

Human societies exhibit numerous feedback loops in:

Technology

Modern technology heavily relies on feedback mechanisms:

Breaking Feedback Loops

Understanding how to interrupt or modify feedback loops is crucial for:

Preventing destructive cycles
Promoting beneficial outcomes
Managing system stability
Creating sustainable changes
