Feedback Loops

Shrink Definition

A feedback loop occurs when the output of a process influences the future behavior of that same process. Positive feedback loops amplify change. Negative feedback loops stabilize change. Human behavior, emotions, relationships, organizations, and habits all operate through interacting feedback loops.

Plain language

Today's actions shape tomorrow's conditions. Tomorrow's conditions influence tomorrow's actions.

Shrink Insight

Many patterns persist because they continuously reinforce themselves.

Why it matters
