Picture the colleague who spends every staff meeting filling the margins of their notepad with tiny squares, loops, and cross-hatched triangles.
Most people in that room assume one thing: they’re not listening.
Managers notice. Teachers notice. The assumption is almost universal.
The psychology says something else entirely.
The habit most rooms openly judge at the table
Doodling is a way of passing the time when bored by a lecture or telephone call.
That framing alone sounds like a criticism, and for decades it was treated as one.
In the past, doodling was often attributed to inattention and was considered to be a sign of mind-wandering, that is, engaging in task-irrelevant thinking accompanied by boredom.
Classrooms have rules against it. Meeting norms discourage it. It signals, socially, that you are somewhere else.
But the brain has its own opinion on the matter, and it turns out that opinion is inconveniently at odds with the social verdict.
What boredom actually does to a busy mind
The real threat to attention is not the pen moving across the page.
It is the mind that has nothing small and gentle to do while it waits.
Daydreaming may seem absentminded and pointless, but it actually demands a lot of the brain’s processing power.
You start daydreaming about a vacation, which leads you to think about potential destinations and how you would pay for the trip.
These cognitions require what psychologists call “executive functioning.”
That is a genuine cognitive load, burning resources that were supposed to be tracking the conversation in the room.
This connects directly to something well-established in attention research: idle minds are not quiet minds. As GCN has reported, nearly half of every waking hour the mind slips somewhere else entirely, a tendency that carries real costs for focus and memory.
The specific thing a doodle does differently from full daydreaming
Researchers had long studied what happens when you give a distracted brain a second task to do alongside the main one.
Usually, performance on both suffers.
Doodling requires very few executive resources but just enough cognitive effort to keep you from daydreaming, which, if unchecked, will jump-start activity in cortical networks that will keep you from remembering what’s going on.
It is a light cognitive anchor, just enough to keep the mind from drifting, not enough to compete with the thing you are supposed to be tracking.
Doodling maintains the mind engaged while utilizing a small portion of available cognitive resources.
That balance, it turns out, is the whole mechanism.
A 29% memory edge that surprised the researchers who found it
Psychologist Jackie Andrade at the University of Plymouth set up a simple, controlled test to find out what doodling actually does to recall.
40 participants monitored a monotonous mock telephone message for the names of people coming to a party.
Half of the group was randomly assigned to a doodling condition where they shaded printed shapes while listening to the telephone call.
Then came an unannounced memory test on everything they had heard.
The doodling group recalled 29% more information on a surprise memory test.
The study was published in Applied Cognitive Psychology and has since been widely cited across the attention and memory literature.
Doodling allowed access to optimal levels of cognitive processing and reduced daydreaming.
The person scribbling in the margin was not the one who missed the point. They were the one most likely to remember it.
A calm reframe for anyone who has been told to put the pen down
None of this means decorating your notebook is a guaranteed memory system or that elaborate drawing during complex tasks is always helpful.
This study suggests that in everyday life doodling may be something we do because it helps to keep us on track with a boring task, rather than being an unnecessary distraction.
The key word is boring.
A routine call, a long lecture, a meandering update meeting: these are exactly the low-engagement moments where the mind is most likely to stage a full escape into planning and fantasy.
A few absent-minded shapes in the margin is a gentle intervention against that escape.
It also connects to a broader pattern in the psychology of everyday behavior: small, barely-noticed habits are often doing more useful work than the visible, deliberate ones. As GCN explored with nostalgia research tracking 1,467 people, the habits we dismiss most quickly sometimes turn out to have the most powerful effects on how we process and connect to the world around us.
So the next time someone at the table is filling the margin with tiny triangles, consider the evidence before assuming they have checked out.
They may be the person who, ten minutes later, remembers exactly what was said.
