Habit Loop

Definition

A feedback cycle consisting of Cue → Craving → Response → Reward that governs automatic behavior.

Step‑By‑Step Demonstration

1. Cue – The trigger (e.g., phone notification).
2. Craving – Anticipation of the reward (e.g., social connection).
3. Response – The habit action (checking the phone).
4. Reward – The satisfaction (messages read).

How to Apply: Redesigning a Night‑time Phone Routine

1. Identify the cue – Phone on bedside table lights up at 10 pm.
2. Modify the cue – Move the charger to the living‑room (cue elimination).
3. Adjust the craving – Replace scrolling with reading a short article (different craving).
4. Change the response – Read for 5 minutes instead of scrolling.
5. Provide a new reward – Note a “sleep‑ready” feeling in a journal (positive reinforcement).

Origins

Expanded from Charles Duhigg’s “cue‑routine‑reward” model; Clear adds the craving stage to capture motivational drive.
