Short Summary
Main recommendation: Treat habits as a three-part loop (cue, routine, reward) and change them by identifying the cue and reward that drive the routine, while making the reward genuinely valuable and planning ahead for moments of willpower failure. Duhigg applies this to customers, employees, and personal behavior, arguing that most daily decisions are habits and that willpower is best managed by pre-planning rather than relying on it in the moment.
Key Points
- Every habit has a cue, a routine, and a reward, and the cue and reward together create a neurological craving that drives the behavior.
- For a product to become habit-forming for customers, the reward must be genuinely valued outside the product itself; Febreze failed at launch until Procter & Gamble added more perfume, after which it became a billion-dollar-a-year product.
- Duhigg cites a study by a researcher at Duke University finding that 45% of daily decisions are actually habits, and he notes most habits are good ones, such as driving or replying to email.
- Starbucks trains employees with willpower habits, since staff who finish long shifts may be tempted to snap at customers.
- Willpower behaves like a muscle that tires over time, so planned responses to predictable breakdown moments take less effort than in-the-moment decisions.
Details Worth Noting
- Concrete instructions:
- Identify your cue, routine, and reward for a behavior you want to change, and focus on the cue and reward rather than only the routine.
- Look for inflection points in your own life or your employees' lives: the times you normally break down, such as afternoons when procrastination on email sets in.
- Create a plan ahead of time for exactly how to respond at each inflection point, so the decision is already made when the moment arrives.
- When a habit is to be instilled in customers, check whether the reward is genuinely valued outside the product context.
- Duhigg's examples for social rewards include Facebook updates and Foursquare badges, which he says derive value from peer standing.
- The speaker says that according to laboratory studies, once you know the cue and craving, you can change almost any behavior.
- The Starbucks example involves recent high school graduates working eight-hour shifts, illustrating the pressure that a structured willpower habit is meant to offset.
Bottom Line
Habits respond to deliberate design: map the cue and reward, make the reward meaningful, and pre-decide your response to predictable failure points so willpower is not the thing you rely on.
