 | Fogg’s B=MAP model: behaviour happens when motivation, ability, and a prompt coincide — so shrink the rep, anchor it to an existing routine, and celebrate immediately so emotion wires the loop before mood negotiates. Context is not backdrop; it is the prompt surface. Fogg First published 2019 - Reprint (2020) · Houghton Mifflin Harcourt · ISBN 9780358003328 |

Key principles
- B=MAP coincidence — Behaviour runs only when motivation, ability, and prompt align in one moment — fix the weakest leg instead of preaching harder wanting.
- Anchor-moment pairing — After an established routine (after I pour coffee), attach one tiny new behaviour — inherited rhythm carries what willpower cannot schedule.
- Ability-first scaling — Shrink until the rep is smaller than resistance — floss one tooth, read one paragraph; ability must not be the bottleneck on day one.
- Prompt-surface design — Visible cues in the right context trigger action — wrong device or room pulls the wrong behaviour before intention speaks.
- Instant celebration wiring — A brief authentic positive emotion right after the rep — a physical shine — teaches the nervous system the loop paid off.
- Emotion-before-motivation — Habits form faster when feeling succeeds the behaviour immediately — waiting for inspiration inverts the sequence Fogg tests.
Core science
Fogg’s Stanford behaviour-design work formalizes B=MAP (Behavior = Motivation × Ability × Prompt) and years of tiny-habits coaching into a teachable method. The book is applied behaviour design — strong on prompt and ability levers, lighter as standalone outcome trials than Wood’s habit diary program. Pair with Wood and Neal on context-cued automaticity and with the Atomic Habits volume on identity and environment sculpting when you need a fuller stack.
Application
Reach for this volume when capture or review habits die at the unlock hijack — honest intent, wrong prompt surface. Use when you need a rep so small it runs before mood debates, plus a celebration ritual that wires success without heroic streak pressure. Open Context design on the Atlas shelf for the mechanism map.
