🍪 Move the Cookie Jar, Not Your Willpower
How a hospital cafeteria changed what people ate without removing a single item.
The Hospital Cafeteria That Rearranged Itself
In a two-phase study published in 2012, researchers led by Anne Thorndike at Massachusetts General Hospital wanted to see whether changing what's easy to grab — not what's available — could shift what people actually eat and drink. First, they added simple color-coded labels to everything in the cafeteria. Then, in a second three-month phase, they changed placement without removing a single item: water was moved to eye level in every cooler, while the least healthy drinks were moved down to harder-to-reach spots.
Willpower has to work against friction every single time it's tested. Removing that friction — moving the tempting thing further away, keeping the wanted habit's tools closer at hand — changes the default choice permanently, without needing willpower to show up at all.
🍪 Redesign the Reach
- Identify the habit you're fighting, then find its physical trigger — what makes it easy to grab or easy to start.
- Add friction to the habit you don't want: put it one room further away, one drawer deeper, one step harder to reach.
- Remove friction from the habit you do want: keep its tools visible and within arm's reach.
- Redesign once, rather than relying on daily willpower to beat a convenient trigger.
You didn't need more self-control. The jar was just too close. 🍪
