The unaccompanied walk: a quiet defence

There is no honest piece of writing on attention in 2026 that does not, somewhere, end up arguing for the walk. So this is the piece. If you are going to read one thing and act on one thing as a result of reading anything I write, please let it be this one. The unaccompanied walk — outside if possible, alone, without anything in your ears — is the single highest-leverage practice on attention and creativity that the actual research supports.

What follows is the brief case.

What the researchers have shown

Marily Oppezzo and Daniel Schwartz at Stanford ran the cleanest experiment in 2014.^[1] They put participants through standardised creativity tests in four conditions: seated indoors, walking on a treadmill indoors, seated outdoors (rolled to a window in a chair), and walking outdoors. They were not measuring attention or wellbeing. They were measuring how many original, useful ideas the participants produced.

Walking produced more original ideas than sitting. The effect was substantial — roughly 60 per cent more divergent thinking output, in the language of the paper. The effect persisted for a short period after the walk ended; ideas continued to arrive while participants returned to seated work. Walking outdoors was best. Walking on the treadmill was nearly as good. The treadmill finding is important. It suggests the effect is not about the view; it is about the rhythmic, low-attention-demand physical activity.

The complementary study from Benjamin Baird and colleagues at UC Santa Barbara found that twelve minutes of an “easy task that allowed mind-wandering” produced a 40 per cent improvement on a creativity test versus twelve minutes of an attention-demanding task.^[2] The condition Baird's team set up was, in practice, a walking-like activity: the brain occupied just enough not to dwell on the test, but not so much that it had no spare capacity for ideas.

A separate strand from Marc Berman and colleagues at the University of Michigan, working on attention restoration theory, has shown that walks in natural settings (parks, wooded areas) produce measurable improvements in subsequent attention-demanding cognitive performance, in ways that walks in busy urban settings do not.^[3] Nature, in their terms, restores. The mechanism is debated; the empirical effect is consistent.

The picture, taken together, is unusually clear. Walking, especially outdoors, especially without external attentional demands, is one of the most reliable cognitive interventions human beings have access to. And almost nothing in modern life is asking us to do it.

Who used to do this

If you read about the lives of the writers, scientists, and thinkers whose work has lasted, one practice keeps appearing.

William Wordsworth walked about ten miles a day. Most of his poems were composed on his feet and written down later. His sister Dorothy's journals make it clear that the entire Wordsworth household assumed that bad weather, by preventing the walk, would prevent that day's work.

Charles Darwin had a path at Down House he called the Sandwalk. He walked it twice a day, every day. On the Origin of Species was substantially worked out on it.

Ludwig van Beethoven walked compulsively through Vienna, often with a notebook to catch musical phrases as they appeared.

Søren Kierkegaard wrote in a letter to his niece: I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it.^[5]

Rebecca Solnit's Wanderlust gathers a rich social history of the walking practice among writers, philosophers, and political figures across centuries.^[4] The pattern is consistent. The walking was not separate from the work. The walking was where the work happened.

None of these people, of course, had earbuds. They had no choice. We have a choice. We have, in aggregate, chosen against it.

What the headphones replaced

It is worth being honest about what is now in our ears on walks. Almost everyone, in most cities, on most walks, is listening to something. A podcast. An audiobook. A playlist. A phone call. The market value of the eight to twelve hours per week the average person spends in earbuds is enormous; entire industries exist to fill it.

The point is not that any of those industries are bad. The podcast you love is a fine podcast. The audiobook is the only way you finish books now. The playlist is what makes the cold morning bearable.

The point is that, before the earbud, the walk was the cognitive setting in which a great deal of your incidental thinking happened. The default mode network had its longest, most reliable daily activation. The slow assembly of half-finished ideas resolved itself, on the walk, while you walked.

You have not lost the walk. You have lost the cognitive setting the walk used to provide.

The minimum effective dose

If you do one walk a day, with no audio, even ten minutes long, you have given the default mode network ten minutes a day to do what it was designed to do. Cumulatively, that is more than an hour a week. More than four hours a month. About fifty hours a year. Fifty hours is what someone spends writing a short book, or working through a difficult relationship, or solving a problem that has been nagging at them for years.

Most of the people I have spoken to who installed a daily walking-without-audio practice noticed, within three to six weeks, that the walk became something they looked forward to. It is not, in their reports, a sacrifice. It becomes one of the best parts of the day, in part because it is the only part of the day in which the input stops.

If you would like a small practical companion for this practice, the studio publishes a printable Walk Log — fifty undated pages, one per walk, with prompts for what you saw and what arrived in your head. It is £4. It is also entirely optional. The walk does not require a log. The walk only requires that you go.

A small instruction

When you finish this article, put the phone down. Put your shoes on. Walk to the end of your road and back, even if it is short. Notice the discomfort in the first three minutes, which is the trained pull of the missing audio. Notice when it passes. Notice what arrives in the space where the audio used to be.

That is the practice. We hope it goes well.
