Map the cue-routine-reward loop

Break a habit into its three parts before you try to change anything.

Why it works

Habits run as automated loops in the basal ganglia so the conscious brain can offload effort. Because the loop executes below awareness, you cannot redesign a habit you have not made visible. Mapping the cue, the routine, and the reward converts an automatic behavior back into an object you can inspect and edit.

How to do it

1. Write down the routine — the behavior itself — in plain terms.
2. Note what immediately precedes it (location, time, emotional state, people, prior action) as candidate cues.
3. Ask what you actually get from it — the felt reward — not what you assume you get.

Evidence

The loop structure reflects established neuroscience of habit learning in the basal ganglia, where context cues trigger chunked action sequences. The practical "map your loop" exercise is a useful application of that science rather than a separately trialed intervention. (mechanistic)

The neuroscience of the loop is solid; the self-diagnosis worksheet is practitioner technique, not a tested protocol.

Common mistake

Assuming you already know the cue and reward instead of observing them — most people are wrong about both, which sends the whole change effort at the wrong target.
