If someone has ever told you to clean up your workspace, stop talking to yourself, or please just pay attention, you may have found the experience mildly demoralizing. Or at least annoying. But science has a different take on some of the habits most commonly written off as flaky, unfocused, or just a bit chaotic. Researchers keep finding that certain behaviors we’re trained to see as problems are quietly connected to how sharp, creative, or cognitively flexible someone actually is.
None of this means every quirk is a hidden superpower. The research is specific, and it’s worth being precise about what it actually shows. But there is a growing body of evidence that some habits that look like distraction or messiness from the outside are, in certain people, signs of a brain that’s doing something more interesting than it appears. Here are eight of them.
1. Keeping a Messy Desk
The tidiness lecture starts young. Clean room, clear mind, goes the general wisdom. But when psychological scientist Kathleen Vohs and her colleagues at the University of Minnesota put this assumption to an actual test, the messy desk crowd had a real edge – at least in one specific department.
The researchers ran three experiments testing what happened when people worked in orderly versus disorderly rooms. In one of those experiments, participants in a disorderly room came out more creative than those in an orderly one. The task involved generating new uses for ping pong balls, and while both groups came up with a similar number of ideas, the ones who worked in the messy room generated suggestions that were rated as more interesting and original by impartial judges.
As the team wrote in Psychological Science, “Disorderly environments seem to inspire breaking free of tradition, which can produce fresh insights.” The neat room, meanwhile, produced more conventional thinking. People made safer choices, donated more money to charity, and picked the apple over the chocolate bar. All admirable. Not especially creative.
The tidy room isn’t better. It’s just optimized for a different outcome. If your workspace looks like a small disaster and you’re still getting things done, you may be benefiting from an environment that keeps your brain from defaulting to the obvious answer.
2. Doodling During Meetings
The person filling the margins of their notebook with spirals and faces while you’re presenting your quarterly figures is not ignoring you. They may be tracking you better than anyone else in the room.
According to EurekAlert’s coverage of the study by Professor Jackie Andrade at the University of Plymouth, subjects given a doodling task while listening to a dull phone message had 29% better recall compared to their non-doodling counterparts. The experiment had participants listen to a monotonous recorded call and then tested what they remembered. Doodlers recalled an average of 7.5 names and places, against only 5.8 for the non-doodlers – a meaningful gap for such a simple intervention.
The reason isn’t magic. Andrade explained that if someone is doing a boring task, like listening to a dull telephone conversation, they may start to daydream. Daydreaming distracts them from the task, resulting in poorer performance. A simple task like doodling may be sufficient to stop daydreaming without affecting performance on the main task.
So doodling works not because it improves processing directly, but because it blocks the thing that actually hurts it. Your brain has limited attention available, and a mild, low-demand activity is just enough to occupy the part that would otherwise start narrating a fantasy version of your weekend. If you’re the kind of person who can’t sit through a long call without drawing something, you’re not losing focus. You’re keeping it.
3. Talking to Yourself
Most people do it. Almost nobody admits to it. And the ones who got caught doing it in front of someone else know the particular social discomfort of trying to explain yourself in real time.
A study published in Acta Psychologica found that reading instructions aloud, compared to reading them silently, helped people sustain concentration and perform better on subsequent tasks. Paloma Mari-Beffa, one of the study’s authors at Bangor University, noted: “Talking out loud, when the mind is not wandering, could actually be a sign of high cognitive functioning. Rather than being mentally ill, it can make you intellectually more competent. The stereotype of the mad scientist talking to themselves, lost in their own inner world, might reflect the reality of a genius who uses all the means at their disposal to increase their brainpower.”
To say something out loud, you have to retrieve the right words, organize them into a sequence, and keep the goal of your sentence in focus until you’ve finished it. That’s a surprisingly demanding process. It forces the brain to be precise in a way that purely internal thinking doesn’t. When someone talks themselves through a task step by step, or argues out loud with a problem they’re stuck on, they’re using language as a scaffold for thinking – not just expressing thoughts they’ve already finished having.
Self-talk that’s purposeful and focused is the kind associated with sharper cognition. The muttering monologue of someone genuinely problem-solving is a different thing from unfocused rambling. But if you catch yourself narrating your decisions as you make them, or working through a difficult email by saying it out loud before you type it, that’s not eccentricity. That’s your brain doing extra work to get it right.
4. Having a Taste for Dark Humor
If you’re the one at the table who laughed at the joke everyone else found mildly offensive, and you’re reading this with a slight feeling of vindication, that’s fair.
Researchers at the Medical University of Vienna recruited 156 male and female volunteers with an average age of 33 and asked them to rate their comprehension and enjoyment of 12 dark humor cartoons. Participants also underwent measurements of verbal and nonverbal intelligence, mood disturbance, and aggressiveness. The results, covered by ScienceAlert, were striking: the subjects who showed the highest levels of dark humor preference and comprehension also scored highest on intelligence measures, had more years of education, and showed the lowest values for mood disturbance and aggression.
Processing a dark joke takes more mental gymnastics than a standard punchline. The brain has to hold the difficult content at arm’s length, parse multiple layers of meaning, find the incongruity, and arrive at amusement – all at once. The team described this as a “complex information-processing task,” one that requires both cognitive capacity and a kind of emotional steadiness.
What’s also interesting is the aggression finding. Intuitively, you might expect that enjoying morbid humor would correlate with higher aggression. The study found the opposite: those most in tune with dark humor had the lowest scores for aggression and negative mood. Appreciating the joke requires clear-headedness – an emotional stability that lets the brain engage with difficult content playfully rather than defensively. If dark jokes make you laugh, the science suggests you’re probably doing fine.
5. Needing Background Noise to Focus
The people who can’t work in silence have been dismissed for years as easily distracted. They might actually know something about how their own brains function.
Research from Ravi Mehta, a professor of business administration at the University of Illinois, found that ambient background noise is a meaningful factor affecting creative cognition. According to the Illinois News Bureau, the study found that a moderate level of ambient noise – about 70 decibels, roughly the sound of a passenger car on a highway – enhanced performance on creative tasks. Not quiet. Not loud. Just persistently, moderately noisy. That’s roughly the volume of a busy coffee shop, which is not a coincidence.
A high level of noise, on the other hand, hurt creativity. The mechanism is counterintuitive but solid: moderate noise increases processing difficulty just enough to push the brain toward more abstract, expansive thinking. Turn the noise up too high and the effect reverses. Processing gets overwhelmed instead of challenged.
As Mehta put it: “Instead of burying oneself in a quiet room trying to figure out a solution, walking outside of one’s comfort zone and getting into a relatively noisy environment like a cafe may actually trigger the brain to think abstractly, and thus generate creative ideas.” If you gravitate toward coffee shops to work on anything that requires actual creativity, you’re not romanticizing productivity. You’re chasing the right kind of cognitive friction.
6. Daydreaming
Every teacher who ever wrote “easily distracted” or “tends to stare out the window” on a report card might want to revisit that assessment.
Research has established that the human brain spends close to half of all waking hours in a state of mind-wandering. Rather than treating this as a design flaw, neuroscientists now believe it’s partly what the brain is built to do during downtime. Brain imaging shows that when a person is not actively focused on a task, a specific group of regions called the default mode network becomes more active. This network, which includes the medial prefrontal cortex and posterior cingulate cortex, is involved in internal thought, memory retrieval, and imagining future events. Researchers believe this network helps the brain simulate possibilities, plan actions, and rehearse outcomes.
The creativity link is particularly well-documented. Researcher Benjamin Baird has noted that daydreaming fosters creativity because the brain’s ability to make novel connections between seemingly unrelated concepts is heightened during mind-wandering episodes. The key distinction, as the research consistently shows, is between purposeless rumination and what psychologists call positive constructive daydreaming – the kind where the mind wanders forward, imagining possibilities rather than replaying regrets. The first kind tends to be associated with lower mood. The second is where creativity lives.
People who let thoughts roam before tackling tricky problems tend to solve more of them than those forced to stay on task. The next time you find yourself three minutes into thinking about something completely unrelated to what you’re supposed to be doing, you haven’t necessarily lost the thread. Your brain may have just switched to a different kind of processing.
7. Staying Up Late
Early rising has a powerful PR team. Every productivity article ever written seems to involve waking before sunrise, and the cultural assumption that disciplined, successful people greet the 5am alarm with enthusiasm is remarkably persistent.
Research on night owls suggests a more complicated picture. Psychologists have noted a consistent tendency for people who naturally stay up late to score higher on measures of verbal and general intelligence. The evolutionary argument is intriguing: ancestral environments made nighttime genuinely dangerous, and venturing into it – or simply staying alert when most others slept – would have required something beyond the ordinary. The brains that stayed active at night were doing something unusual.
Modern research reinforces this pattern. Studies repeatedly show that the brains of night owls show different patterns of neural connectivity and activation compared to morning types, with stronger connections in areas associated with sustained attention and working memory. None of this means early risers are less intelligent – different chronotypes have different strengths. But if you’ve always functioned better after 10pm and felt guilty about it, you’re in cognitively decent company. Creativity historically keeps late hours. Einstein reportedly worked into the early hours. Darwin wrote late by candlelight. The phrase “burned the midnight oil” exists for a reason, and it isn’t about insomnia.
8. Preferring to Write Things Down Rather Than Say Them
In meetings, some people speak freely. Others sit quietly, listening, and then send a follow-up email that is somehow clearer and more useful than everything said out loud. Those people often get misread as introverted or hesitant. They may just have a stronger preference for a mode of communication that forces them to think more precisely.
Writing requires commitment in a way that speaking doesn’t. When you say something wrong in conversation, it evaporates. When you write it down, you can see it. You can revise it. The act of putting a thought in writing forces you to confront whether the thought actually holds together, and people who prefer written communication tend to be doing exactly that kind of self-editing in real time. It’s not about being shy. It’s about not being satisfied with an approximate version of the thought.
The cognitive research on this is consistent with what we know about writing as a tool for thinking. When you write, you engage the same language systems as speech, plus visual processing and working memory in ways that verbal-only communication doesn’t require. The result is that writing tends to produce more organized, more examined thinking. People who gravitate toward it as their primary mode of expression are often doing so because they’ve noticed the output is better. They’re right. And if you’ve ever composed a careful email before a difficult conversation because you wanted to get the wording exactly right, you already know this.
What to Do With All of This
It would be tidy to wrap things up here and say: the pile on your desk is proof of genius, the muttering is a cognitive tool, and the daydreaming was working all along. But that’s not quite what the research shows, and presenting it that way would be doing you a disservice.
What the research actually shows is that these habits carry cognitive benefits in specific contexts. A messy environment helps with creative ideation but doesn’t help you follow rules or make careful decisions. Doodling helps you pay attention during boring tasks but hasn’t been shown to help with everything. Dark humor appreciation correlates with higher IQ in a study of 156 people, which is notable but also a relatively small sample. Self-talk helps focus when you’re actually focused on something, not when you’re just narrating your thoughts into the void.
The larger point is that the habits we’re most often told to correct aren’t always problems. Some of them are just different strategies your brain has found for doing what it needs to do. If you’ve spent years apologizing for the state of your desk or feeling vaguely embarrassed about muttering while you work through a problem, you’re probably allowed to let some of that go. The goal isn’t to perform the appearance of a well-organized mind. It’s to actually think well – and for some brains, the less conventional route is the more effective one.
