I used to apologize for it. In meetings, in lectures, in any situation where I found myself with a pen and a piece of paper and nothing specific to write — I would draw. Shapes, mostly. Patterns, arrows, words written and then written again in slightly different ways, faces that weren’t quite faces, geometric forms that had no purpose and no destination. And whenever someone noticed, I would feel faintly embarrassed — as though I had been caught doing something childish, something that signaled I wasn’t paying proper attention.
What I didn’t know then — and what the research now makes clear — is that I was paying better attention precisely because of the scribbling. And that the random marks accumulating at the margins of my notes were doing something to my brain that sitting still and trying to focus had never quite managed on its own.
This post is about what happens in your brain when you put a pen to paper without an agenda — and why it might be one of the simplest and most overlooked ways to keep your mind sharp, creative, and genuinely alive.
The moment I stopped apologizing for it
The turning point came during a particularly difficult period at work — the kind where there was too much to think about and not enough clarity to think it through. I had been staring at the same problem for days, turning it over in my head without getting anywhere, trying to think my way to a solution through sheer mental effort and producing nothing except a growing sense of frustration.
One afternoon, without particular intention, I picked up a pen and started drawing on the back of a piece of paper. Not related to the problem. Not a mind map or a brainstorm or anything organized. Just marks — shapes connecting to other shapes, words written without context, lines that went nowhere and came from nowhere. It lasted maybe fifteen minutes. And when I stopped and looked back at the problem, something had shifted. Not dramatically — I hadn’t solved it in the way that happens in films, with a sudden flash of insight and a moment of triumph. But the edges of it had softened. The angles had changed. There was a way through that I couldn’t quite see before, and now, imprecisely but unmistakably, I could.
I assumed it was coincidence. It happened again the next week. And the week after that. And eventually I stopped assuming it was coincidence and started paying attention to what was actually happening when I picked up the pen.
“The scribbling wasn’t distraction. It was thinking — just a different kind of thinking than the kind I had been taught to value.”
What your brain is doing when you scribble
When you engage in unstructured mark-making — doodling, free writing, random drawing — you activate what neuroscientists call the default mode network. This is the brain’s resting state network, active when you are not focused on a specific external task, and it is associated with some of the most important cognitive functions your brain performs — creative thinking, making connections between unrelated ideas, self-reflection, future planning, and the consolidation of learning and memory.
The default mode network is suppressed when you are in focused, task-directed thinking — the kind of thinking most of us default to when we are trying to solve a problem or learn something new. That focused thinking is valuable and necessary. But it has a significant limitation — it tends to work within existing frameworks and familiar patterns. It is good at following established paths. It is less good at finding new ones.
Scribbling activates the default mode network while keeping a light thread of engagement — the physical act of moving the pen — that prevents the mind from fully disengaging. This combination creates a state that researchers have described as productive mind-wandering — a condition in which the brain is free to make novel connections, approach problems from unexpected angles, and generate ideas that focused thinking would never have reached, while remaining just engaged enough to capture and develop them when they arrive.
This is why the insight that comes while you are doing something else — in the shower, on a walk, while cooking — is such a universal human experience. The default mode network does its best work when focused attention is temporarily released. Scribbling is a portable, controllable, repeatable way to create that release deliberately rather than waiting for it to happen accidentally.
What handwriting specifically does that typing cannot
There is something important about the pen and paper specifically — not the keyboard, not the tablet with a stylus, but the physical act of making marks by hand on a physical surface. The research on this is clear and somewhat counterintuitive in an age where typing is faster, more legible, and more convenient in almost every practical respect.
Handwriting engages significantly more of the brain than typing does. The complex motor movements required to form letters by hand activate neural circuits in the motor cortex, the visual cortex, and areas associated with language processing simultaneously — creating a richer, more integrated pattern of brain activation than the repetitive, simplified movements of keyboard typing. This richer activation is associated with deeper encoding of information, stronger memory formation, and greater retention of what is written.
Studies comparing students who took notes by hand with those who typed found that hand-writers consistently showed better understanding and retention — not because they wrote more but because the slower pace and the motor engagement forced more active processing of the material. You cannot transcribe everything by hand as you can by keyboard — which means hand-writing forces you to summarize, select, and synthesize in real time. That active processing is learning. The transcription is not.
Free writing and scribbling take this further. When there is no content to transcribe — when the pen is moving freely without direction — the brain is not processing external information at all. It is generating its own. The motor engagement keeps a light current of neural activation flowing, but the content is entirely internal — memories, associations, half-formed ideas, images and words that surface from below conscious thought and become visible on the page before the analytical mind can intercept and evaluate them. This is why free writing so often produces surprises — things you didn’t know you thought, connections you didn’t know you’d made, insights that feel like they came from somewhere else but were yours all along.
“Typing captures what you already think. Handwriting — especially free, unstructured handwriting — discovers what you didn’t know you thought.”
What doodling specifically does for focus and memory
A study published in Applied Cognitive Psychology found that people who doodled while listening to a monotonous phone message retained 29 percent more information than those who did not doodle. The explanation offered by the researchers is that doodling occupies just enough cognitive capacity to prevent the mind from wandering into full daydreaming — which is a state of significantly lower information retention — while leaving sufficient capacity for the primary task of listening.
This is the opposite of the assumption most people make about doodling — that it is a symptom of distraction rather than a management of it. In reality, the choice is rarely between doodling and perfect focus. It is almost always between doodling and full mind-wandering. And doodling, by that comparison, is the significantly more productive option.
I think about all the meetings where doodling was subtly discouraged — where the implicit expectation was that undivided attention meant stillness, and that any movement of the pen that wasn’t note-taking was a sign of disengagement. The research suggests the opposite. The people drawing quietly at the margins of their notebooks were very likely retaining more of what was said than the people sitting still and struggling to maintain focus through sheer will.
Free writing and what it does to your thinking over time
Free writing — writing continuously for a set period without editing, without direction, and without stopping to evaluate what is being produced — is one of the oldest creative and cognitive practices available, and one of the most consistently underused. Writers have used it for centuries. Therapists recommend it for emotional processing. Educators use it to unlock thinking that structured prompts cannot reach.
What it does to your thinking over time is cumulative and significant. The regular practice of putting words on paper without judgement — of externalizing the internal monologue that runs constantly and giving it somewhere to go — gradually builds a relationship with your own mind that is more honest, more fluid, and more creative than the relationship most people have when all their thinking stays internal.
Internal thinking is constrained by the same patterns it always uses. It circles familiar territory, repeats familiar conclusions, arrives at familiar places. Written thinking — even free, unstructured, apparently purposeless written thinking — escapes those circuits. The act of writing something down makes it concrete enough to examine, question, and build upon in ways that pure mental rumination cannot. Ideas that would have dissolved or looped endlessly in your head become, once written, things you can actually work with.
Over months and years of this practice, something quietly extraordinary happens. The thinking becomes more original. The problem-solving becomes more lateral. The mind becomes more comfortable with uncertainty, more willing to follow an idea to an unexpected place, more capable of the kind of genuine creativity that most people assume is a talent you either have or don’t. It is not a talent. It is a muscle. And scribbling on blank paper is one of the most straightforward ways to train it.
How to start — and why the bar is as low as it gets
You need a pen and a piece of paper. That is the entire equipment list. No special notebook, no particular pen, no dedicated time or space or system. The back of an envelope works. The margin of a receipt works. A cheap notebook bought for a pound works exactly as well as an expensive one.
Start with five minutes. Set a timer and put pen to paper — drawing, writing, or both — without stopping and without judging what appears. If you are drawing, draw whatever comes — shapes, patterns, faces, things you can see, things you are imagining, things that have no referent in the real world. If you are writing, write whatever arrives — what you are thinking, what you notice, what you feel, what you had for breakfast, the sentence you are struggling to write and why, the problem that has been sitting just out of reach and what it looks like from different angles. Do not edit. Do not stop. Do not evaluate until the timer goes off.
Then look at what you produced. Not critically — just with curiosity. Notice what surprised you. Notice what appeared that you weren’t expecting. Notice whether anything that arrived on the page is something you want to keep and develop. Most of it won’t be. Some of it will. That some is worth far more than the cost of the five minutes, and it would never have arrived any other way.
Keep a small notebook and pen somewhere visible — on your desk, on your bedside table, in your bag. The barrier to scribbling is almost entirely about access. When the pen and paper are right there, the practice happens. When they have to be found, it almost never does. Remove the barrier and the habit follows naturally.
The intelligence that scribbling protects
There is a kind of intelligence that is not measured by tests and not developed by structured learning — the intelligence of making unexpected connections, of thinking around corners, of finding the non-obvious solution to a problem that the obvious approaches have failed to reach. It is sometimes called creative intelligence, sometimes lateral thinking, sometimes simply wisdom — the accumulated capacity to see things from angles that most people haven’t considered.
This intelligence atrophies without use. And in a world where most of our cognitive engagement happens on screens — in structured formats, within algorithmic frameworks, consuming content that someone else made rather than generating anything of our own — it is getting less use than it has at almost any other point in human history.
Scribbling on a blank sheet of paper is one of the most direct ways to exercise it. Not because it is sophisticated or structured or efficient — but precisely because it isn’t. Because it asks your brain to generate rather than consume, to wander rather than follow, to make something from nothing rather than respond to something already made. That generative capacity is the core of human intelligence. And it needs practice, just like everything else worth keeping.
Pick up a pen today. Put it on paper. See what arrives. That is the entire practice — and it is more than enough.
Today — not tomorrow, not when you have the right notebook — pick up any pen and any piece of paper and scribble for five minutes. Draw, write, or both. Don’t judge what appears. Just make marks and let your brain do what it was built to do when nobody is telling it what to think. Explore more on Quiet Growth for simple daily habits that support a calmer, more focused life.
