What Moving House Did to Commuters' Habits, and a 14-Day Plan for Your Own Move

Marisol is an invented example, but her situation is an ordinary one. She moves from a third-floor flat to a house forty minutes away, and on the first Monday she opens the wrong cupboard for a mug three times. Her running shoes are in a box marked “misc.” The pharmacy where she used to buy coffee on the way to the train is now a place she would have to plan a trip to. By Wednesday she has noticed something odd: she has not had a single “I should really…” thought about snacks, scrolling or sleeping in. The old cues are in another postcode, and the old routines are standing in the hallway with nowhere to go.

A big life change is the cheapest moment to change a habit, because habits are cued by context and a change of context removes the cues. The research behind this, the habit discontinuity hypothesis, suggests the opening lasts weeks to a few months, not years, and almost all of it comes from studies of commuting and everyday sustainable behavior. This post covers what those studies found, how far they can be trusted, and what a sensible first fortnight looks like.

What is the habit discontinuity hypothesis?

The habit discontinuity hypothesis says that when a change of context disrupts a person’s habits, they are more likely to think about what they do and act on their values, instead of repeating the old routine. It was developed by Bas Verplanken and colleagues at the University of Bath. The word “discontinuity” is the useful part: the habit is not argued away, it is interrupted because the cues that ran it are gone.

This differs from the fresh start effect, where a calendar landmark such as a new year or a birthday gives you a mental clean slate. A calendar date changes how you feel about yourself while your kitchen stays the same. A move changes the kitchen. That is why this idea has been tested on what people do, not only on what they intend.

What did the three studies find?

Verplanken, Walker, Davis and Jurasek (2008, Journal of Environmental Psychology, 28(2), 121-127) compared university employees who had recently moved house with those who had not. Environmentally concerned recent movers drove to work less than equally concerned people who had not moved. People who cared about the environment but had stayed put did not show the same shift. I read the abstract and a later paper’s description of it, which gives the sample as 433 staff at one English university and defines “recent” as a move within the past 12 months.

Walker, Thomas and Verplanken (2015, Environment and Behavior, 47(10), 1089-1106) followed staff of a UK environmental charity, WWF UK, across an office relocation, with surveys 19 months before the move and again one week and four weeks after it. Travel habit strength dropped after the move for everyone, including people whose commute did not change. For those who did switch mode, the old habit faded gradually over the following weeks while the new one strengthened. A summary from the Association for Psychological Science reports about 200 staff, with train use rising from 19% to 56% and car use falling from 55% to 22.6%. The old office was a 25-minute walk from a station; the new one was seven minutes.

Verplanken and Roy (2016, Journal of Environmental Psychology, 45, 127-134) ran a field experiment with 800 participants, half of them recent movers matched with households that had not moved. Half received a sustainability intervention. The intervention worked better for the movers after controlling for past behavior, habit strength, intentions, values and norms, and the authors estimated the window at about three months. The outcome was self-reported frequency of 25 environment-related behaviors, measured at baseline and eight weeks later. The Wood, Quinn and Kashy diary study post mentions this experiment in passing; the other two studies are covered here for the first time.

How far can these results be trusted?

Not very far, and the authors say so. The strongest independent check is a 2016 analysis in PLOS ONE of about 18,000 respondents in the UK Understanding Society survey. It found the same direction: the link between environmental attitudes and lower car commuting was strongest soon after a move and shrank with years at an address. But the effects were small (odds ratio 1.04 for the attitude-by-time interaction), the data were cross-sectional, so nobody was tracked through a move, and the attitude scale had nine yes/no items with modest reliability. The authors also noted that the original 2008 sample came from a high-income area and that the 12-month cutoff in that study was arbitrary.

Other limits are plain. Walker’s WWF staff were employees of a pro-environmental charity, and attitudes did not predict who changed mode; the researchers suggest the shorter walk to the new station may matter more than information or conviction. Verplanken and Roy relied on self-report. And every study measured travel or green behavior. I read none that tested sleep, exercise, eating, a breakup or a new baby, so applying the idea to them is reasoning by analogy. A move or job change is also a busy, tiring stretch, which may leave less room for deliberate effort just when the cues are loosened.

One result is easy to miss: in the WWF study, old habits did not vanish. Staff who had switched to the train still felt a pull toward driving a month later. A new context makes change cheaper, not automatic.

What should the first 14 days in a new context look like?

Take what the studies support and keep the rest modest. The hypothesis predicts that your old behavior loses its cues and that your values get more say. Nothing predicts that a good new behavior installs itself. So the plan is to use the loosened period deliberately, pick one change, and protect it.

Days 1-2: audit what the move broke. List what your old routine leaned on and what survived. The habits scorecard walkthrough does this in ten minutes for a morning. Gaps in the list are habits that have lost their grip, good ones included.

Day 3: choose one behavior and place its cue. Marisol’s pick is a 20-minute walk before work. Shoes go by the door and the route gets walked once on a free afternoon. Choosing early matters because in week one nothing in the new place has been decided yet, and whatever you drift into first becomes the default.

Days 3-14: repeat it in one place and at one time. Repetition inside a stable setting is how a new habit forms. A fixed cue and a fixed time make the setting stable. Do not expect it to feel automatic by day 14. Lally and colleagues’ study found a median of 66 days for habit formation with a range of 18 to 254, covered in this post on the 66-day range.

Day 14: review, then extend the supports. The outcome to check is simple: which things happened without a fight? Keep scaffolding, such as reminders and an outside check, under the ones that did not. The three-month window in Verplanken and Roy suggests there is still room after day 14, so a missed fortnight is not a lost cause.

Why does the first morning in a new place go wrong so often?

Because the alarm was one of the cues that did not move. The old wake-up leaned on a bedroom’s light, a street’s noise and a commute that took a known time, none of which exists in the new flat. It is the one routine every other routine depends on. I would treat the wake-up as the first thing to anchor, which is where an outside check earns its place in the plan above.

In short, three studies suggest a move shakes habits loose for somewhere between a few weeks and a few months, the evidence is about commuting, and the effects are small on average. For one person with one habit they want different, that is a reason to act in the first two weeks, with a single change, and to stop trusting that the cue will be there tomorrow.
