The Great Mental Models Volume 3: Systems and Mathematics

There are two basic types of feedback loops: balancing and reinforcing, which are also called negative and positive. Balancing feedback loops tend toward an equilibrium, while reinforcing feedback loops amplify a particular process.

The faster you get accurate feedback, the more quickly you can iterate to improve.

A feedback loop is when the outputs (information) of a system affect its own behaviors.

more progress you will make toward what you want to achieve.

correctly. A critical requirement is learning how to filter feedback. Not all of it is useful. The more quickly you learn to identify good feedback and accept and incorporate it, the

The people you spend the most time with are the ones who give you the most feedback on your behavior and thus have the most impact on the choices you make and the ways you change.

Feedback loops are everywhere in systems, making them a useful mental model.

Systems have certain inflection points where they change from one state to another. It doesn’t help us to focus solely on the tipping point and ignore the work required to bring a system there. Because the inputs that tip a system into a new state tend not to have a linear effect—the final unit of input that leads to the change in state has an outs

The final unit of input before the change has a disproportionate impact.
