Temptation bundling: pair what you want with what you should do

Good habits tend to have costs now and benefits later. Bad habits are the reverse. Temptation bundling, a term coined by behavioral scientist Katherine Milkman, attacks that asymmetry directly: you take something you crave and make it available only while doing something you avoid. The gym gets the page-turner audiobook. The pile of admin gets the expensive coffee. The reward arrives now, attached to the behavior, which is exactly the shape the brain’s habit system wants.

The research

In the original study, participants who wanted to exercise more were given an iPod loaded with tempting audiobooks that they could only access at the gym. Compared with a control group, they made significantly more gym visits over the following weeks. A second group was simply encouraged to bundle on their own with their own audiobooks, and they also improved, though less. Both effects faded over time, especially after a break for the holidays, which is a useful reminder: bundling is a strong starter, not a permanent engine.

Later work found that many people were willing to pay for a gym-restricted audiobook service, suggesting they understood the mechanism and wanted the restriction imposed on them. That is the commitment-device side of bundling: you are hiring your future cravings to do your future work.

The rules that make it work

1. The want must actually tempt you. If you would not mind skipping it, it will not pull you to the habit. Pick something you feel slightly guilty about.
2. The restriction must be real. An audiobook you also listen to in the car is not a bundle. Commit out loud, or use a device or account that lives at the gym.
3. The want should not undo the should. A pastry after every run works against the run. A pastry during the hardest task of the week does not. Match the reward to the goal; our 50 reward ideas list is sorted for this.
4. Refresh it. Bundles fade as novelty fades. Swap the want every month or two: a new series, a new podcast, a new café.
5. Add a tracker for the long run. Once the bundle has done its job of getting you through the first weeks, a visible card of punches becomes the reward that lasts. The bundle starts the loop; the card keeps it running. See the habit loop for the mechanics.

Bundling versus reward-after

Temptation bundling is a during-the-habit reward. “Reward yourself after” is an after-the-habit reward. Bundling is stronger for habits you actively dread, because the pleasure and the pain happen at the same moment and the pain is diluted. After-rewards are better for habits that are merely tedious, and for milestones, like a full card. Most people benefit from both: an audiobook at the gym and a massage after twenty sessions.

When it does not work

Bundling assumes the habit is possible and merely unpleasant. It does not fix a habit that is too big, badly cued, or attached to a life that does not have room for it. Fix those first with the methods in how to be consistent, then add a bundle to make the first weeks easier. And it works less well for people whose “want” is not scarce, so if you already have unlimited access to the pleasure, the bundle has nothing to trade.
