Feedback loops

Feedback loops: A loop is where an effect returns to change its own cause. Reinforcing loops amplify; balancing loops resist.

Free — no account needed to read

A loop is where an effect returns to change its own cause. Reinforcing loops amplify; balancing loops resist.

Try it now

Take something that keeps happening. Draw the parts and arrows, and find a path that returns to where it started.

What to do with the answer

Mark the delays, then pick a realistic break point rather than the ideal one.

Where it misleads

A drawn loop is a hypothesis about a system, not the system. Test it before acting on it as fact.

The module it belongs to

  • Systems Thinking — Understand connections and consequences

The book behind it

  • Thinking in systems — Its big ideas, in our own words.
