Why does positive feedback loops fail?

The most common reason positive feedback loops fails: Treating 'positive feedback loop' as always good. The word 'positive' refers to directionality, not value. A reinforcing loop that amplifies anxiety, debt, or distrust is still a positive feedback loop — it just amplifies in a direction you don't want. Confusing the technical term with the colloquial one leads people to seek reinforcing loops indiscriminately, when sometimes what they actually need is a stabilizing one.

The fix: Identify one reinforcing loop currently active in your life — positive or negative. Map the cycle explicitly: What is the initial condition? What does it produce? How does that output feed back as input? Write it as A -> B -> C -> A. Then ask: is this loop amplifying something I want more of, or something I want less of?

The underlying principle is straightforward: Some loops reinforce themselves — success breeds more success or failure breeds more failure.
