You did not stop running because you got lazy. You stopped because you moved apartments, and the new front door faces a busy road instead of a park, and the shoes ended up in a closet you don't open. Six weeks later you're telling yourself a story about discipline. The truth is duller and stranger: your running habit was never entirely inside you. Half of it lived in a hallway you no longer walk through.

This is one of the most disorienting findings in behavioral science, and almost nobody is told about it before it happens to them. Habits are not stored purely as willpower or identity or resolve. They are stored as associations between a stable context and a response — and when the context changes, the association goes quiet, often overnight. Which means that every major life change is also, silently, a demolition of behaviors you thought you owned.

And it means something more hopeful, which is the reason to keep reading: the same demolition that destroys your good habits also, briefly, unlocks your bad ones.

The habit you thought was yours was partly the room's

Psychologists call this the habit discontinuity hypothesis, developed largely through the work of Bas Verplanken and Wendy Wood. The core claim: habitual behavior is cued by stable environments, so when the environment is disrupted, the behavior loses its trigger and must be consciously re-decided.

Wood and colleagues demonstrated this with transfer students — people who had moved from one university to another. For students whose exercise routines were strongly habitual, the strength of the old habit predicted continued exercise only when the relevant context stayed the same. When the context changed, habit strength stopped predicting behavior. The habit didn't transfer. It stayed behind, attached to the old gym, the old schedule, the old walk across campus.

Sit with the weirdness of that. A behavior you performed hundreds of times, that felt effortless, that you would have described as "who I am" — and it turns out a meaningful chunk of it was outsourced to a building.

Verplanken's research on environmental change found something complementary: people who had recently relocated were more responsive to interventions aimed at changing their commuting behavior. The move had loosened the automaticity. They were, temporarily, making decisions again rather than executing cached ones.

This is the mechanism behind an experience nearly everyone has had and misfiled. The new job that quietly ended your reading habit. The baby that dissolved a decade of morning workouts. The breakup that took your cooking with it. You blamed your character. It was mostly your calendar and your kitchen.

Why your brain does this on purpose

Automaticity is a bargain your brain strikes. Behaviors that have been repeated in a consistent context get demoted from deliberate decisions to cue-triggered responses. That's the whole point — it frees attention for things that actually vary. The cue does the remembering so you don't have to.

But the price of that efficiency is fragility of a specific kind. A habit isn't robust to the loss of its cue, because the cue was doing the work. Remove it and the behavior doesn't degrade gracefully; it simply doesn't fire. You don't feel a pull you resist. You feel nothing at all, and then one Tuesday you notice a month has gone by.

This explains why habit collapse after a life change so rarely feels like a struggle. Struggle implies a competing urge. What people actually report is absence — "it just stopped happening." That's not moral failure. That's a cue-response chain with a missing first link.

The window nobody tells you to use

Here is the asymmetry that makes this idea worth more than a diagnosis.

Disruption doesn't discriminate. It unhooks the good habits and the bad ones together. The evening drink that was welded to a specific couch. The doomscroll fused to a specific commute. The snack that lived in a specific cupboard at a specific hour. When you move, switch jobs, change schedules, or have your routine blown apart by circumstance, all of those associations go slack at once.

For a period — weeks, not years — your behavior is unusually available to deliberate choice. You are running on intention rather than automaticity, because automaticity has nowhere to grab. This is precisely when interventions work that would bounce off you in a stable life.

Most people spend that window trying to restore the old life as fast as possible. They rebuild the exact routine, reflexively, including the parts they'd been meaning to abandon for years. The cupboard gets restocked. The couch gets its function back. Automaticity re-forms around whatever you happened to do in the first few weeks, and the door closes.

The move you should make instead: treat the disruption as a design opportunity, and be deliberate about what you let re-attach.

And critically — do this on the small side. A transition is a period of high cognitive load, not high capacity. The window is one of plasticity, not strength. People who use a move to launch an ambitious new regime tend to fail, then conclude that transitions are bad times to change, when what actually failed was the size of the ask. The transition removed the resistance. It did not hand you extra energy.

What to do when the change is not your choice

Most life changes aren't decided in a planning meeting. A layoff, an illness, a caregiving responsibility, a partner's relocation. It feels absurd to talk about "design opportunities" in the middle of a life you didn't pick.

But the mechanism doesn't care whether you consented. The cues are gone either way. And the alternative to designing the new context is not neutrality — it's letting whatever you do in the first chaotic weeks become the new automatic, because that's what repetition in a stable context always produces. Your brain will build habits from the rubble regardless. The only question is whether anyone was watching what went in.

The kindest version of this is small. One anchored behavior. One cue you place on purpose. Not because it will fix your life, but because in a period where nothing feels chosen, choosing one repeated thing is a way of getting a hand back on the wheel.

Your next moves

  • Name the change you're inside of. Write down one disruption from the last three months — new job, new home, new schedule, new baby, new grief. Then list the behaviors that quietly stopped. Not to feel bad about them; to see that they went together, and that this is evidence of a mechanism rather than a verdict on you.
  • Pick one bad habit to leave in the old context. Something that was welded to a place or time you no longer inhabit. Don't rebuild its cue. Don't restock its cupboard, re-download its app, or recreate its chair. Non-restoration is the cheapest behavior change available, and it is only cheap right now.
  • Physically place one cue for one small habit, today. Not a plan — an object. Shoes by the new door. The book on the pillow. The water glass next to the coffee maker. You are re-attaching a behavior to an environment, so it has to happen in the environment.
  • Shrink the new habit until it feels almost embarrassing. Two pages. One stretch. Three minutes. Repetition in a stable context is what builds automaticity — not effort. During a transition, effort is the scarce resource and repetition is the goal.
  • Give it a fixed slot for the next two weeks. Same cue, same rough time, same place. You are not testing your commitment. You are manufacturing the stability that the habit will eventually be stored inside of.

The part that's actually good news

If you've been carrying the belief that you're someone who "can't stick with anything," look hard at when your habits died. My guess is they didn't erode. They ended abruptly, in the same season you changed something structural about your life, and you read the coincidence as character.

You were never fighting yourself. You were standing in a room that had stopped reminding you who you were trying to be.

Cadence is built around the small end of this: one habit at a time, sized so it survives a hard week, anchored to something in your actual day rather than to a burst of motivation you can't reorder. It's most useful precisely when your life just changed and you have a short window to decide what re-forms — which is not the moment for an ambitious system, but for a small repeated thing you can carry into the new room. If you're standing in that window right now, start with one small step and let the repetition do the rest.
