Temptation Bundling

The term comes from the behavioral scientist Katy Milkman, whose research at the Wharton School tested a simple version: participants could listen to gripping audiobooks they wanted to hear only while they were at the gym, and they went to the gym more often. James Clear uses the idea in Atomic Habits for the second law, make it attractive. His reasoning is that the anticipation of a reward, not the reward itself, is what gets us moving; the brain releases dopamine when it expects something pleasant. A habit that is dull on its own can borrow that anticipation from something enjoyable. Clear combines the idea with habit stacking in one formula: after my current habit, I will do the habit I need; after the habit I need, I will do the habit I want. The order matters. The pleasant thing has to come with or after the necessary one, never before it, or the bundle turns into a reward for nothing. It works best when the treat is something you genuinely crave and is kept for the bundle alone.
