Map the feedback loop

Ask whether the consequence feeds back and amplifies or dampens itself.

Why it works

Some consequences loop: an effect changes the conditions that produced it, either reinforcing (snowball) or self-correcting (thermostat). First-order thinking treats effects as one-shot; spotting the loop reveals whether a small move compounds into something large or fades. Identifying the loop’s sign is what distinguishes a runaway outcome from a self-limiting one.

How to do it

1. After naming a consequence, ask whether it changes the inputs that caused it.
2. Decide if the loop reinforces (amplifies) or balances (dampens) the effect.
3. For reinforcing loops, plan for the larger-than-expected magnitude.

Evidence

Draws on systems-thinking concepts of reinforcing and balancing feedback, which are well established as descriptions of how complex systems behave. Applying them as a personal decision check is a reasoning heuristic. (mechanistic)

Feedback-loop dynamics are well described in systems theory; using them as a decision checklist is applied heuristic, not a trial.

Common mistake

Treating an effect as a single event when it’s actually a reinforcing loop, so you under-prepare for how big it gets.
