This episode digs into the neuroscience of clutter: how multiple objects compete for neural representation in visual cortex, why subjective messiness tracks cortisol better than objective mess, and how the brain uses the environment as external memory. Then it turns to ADHD specifically — reduced sensory gating, working memory loops, and why a sticker on the washing machine isn't a crutch but a load-bearing wall. If you've ever felt paralyzed by the exact mess you're trying to clean up, this one's for you. ## The prompt > I'd like to chat today about what clutter does to the human brain. As you know, I've been on a major organisation kick for the past few months, or rather I've seized a very stressful apartment move as an opportunity to step up from IKEA storage to having the type of storage system that is more typically found in commercial and industrial settings. I now proudly own Euroboxes, industrial shelving, tip bins and the like. Getting our new rental set up has been a huge amount of work, I think more than either of us expected, or maybe it just feels that way because we're both parenting while doing this for the first time. The hard part isn't so much unboxing and finding a new place for everything yet again, which is hard, but all the little things that add up. I had a home server and a couple of baby cameras for keeping an eye on Ezra. It's the ethernet runs that have to be done all over again, the washing machine that needs to be connected and the jostling of trying to find a new home for all your belongings in a new space. We're almost at the end of the process. But sometimes, just before you finally get order, things got temporarily worse. Hannah is finishing a bookcase that she got and did an IKEA hack for. So all her book collection is now in construction bags in the living room. So our place now looks almost exactly like it did when we first moved in. Whereas in the living room you can't take a few steps without running into something. The cause may seem obvious, but I notice that I'm short tempered and in a bad mood. And when our space finally cleared, I suddenly felt a sense of calm and order.The challenge I'm grappling with is that for me this really feels like something I can't exactly control. I have ADHD and an overwhelming sensory environment with visual clutter and trip hazards everywhere is kind of a nightmare for me. I could try to grin and bear it, but it feels like someone is poking at me from all directions all of the time.I know that sometimes things get messy before they get better, but sometimes the sheer stress of the messiness actually prevents you from getting those last few decluttering things done.What thoughts and tips do you have for somebody like this? My wife is an architect and it fascinates me how we're both creatives, but our brains work so differently. She doesn't find temporary clutter stressful because her brain is mentally slotting everything into place, whereas mine is just screaming at me to avoid falling over that box or tripping on that loose cable. How can those who find such environments sensorily overwhelming keep their calm long enough to restore order? And have other ADHDRs also find relief in storage and organisation systems? I mentioned before that my systems feel ridiculous even to me. I have a sticker on a washing machine that reminds me which setting to use. I think the stress and the lack of stress comes from having an orderly visual environment that provides just the information I need and nothing more. ## Show notes Clutter isn't an aesthetic problem. It's a load on specific brain systems, and it can be measured. Research from the Princeton Neuroscience Institute showed that when multiple objects are visible at once, they compete for neural representation in visual cortex — the brain has to actively suppress what you're not looking at, and that suppression costs metabolic resources. A UCLA study of sixty dual-income families found that women who described their homes as cluttered had flatter diurnal cortisol curves, a signature of chronic stress. Crucially, the subjective experience tracked cortisol better than an objective clutter rating did. Same amount of stuff, different stress signature. Two more mechanisms stack on top. The brain uses the environment as external memory — cognitive offloading — and an orderly space provides just the information you need while a cluttered one forces constant re-evaluation of relevance. And trip hazards impose motor vigilance: a continuous, low-grade demand to monitor your body's position relative to a hazard, drawing on the same executive resources you need for everything else. For people with ADHD, the arithmetic changes. Executive function is already working harder at baseline, so clutter consumes a resource that was already scarce. Reduced sensory gating means more of the room gets in by default. Working memory struggles to suppress open loops, so every visible object stays active and competes for the same limited workspace. That's why storage systems aren't a nice-to-have — they're compensatory tools doing the gating the brain isn't doing on its own. The relief comes from externalising executive function: labels, bins, categories, dedicated homes. The systems look absurd from the outside because they're calibrated to a specific executive profile. A sticker on a washing machine is ridiculous to someone whose brain holds the setting without effort — and load-bearing to someone whose brain doesn't. The cruelest part is the loop: clutter imposes cognitive load, the load reduces the capacity to plan and execute the decluttering, and the unfinished decluttering produces more clutter. The demolition phase — where things get worse before they get better — is exactly when you need the most executive function. If you have a strong mental model of the finished state, that model buffers you. If you don't, the visual reality wins and the stress response fires before the reward arrives. The way out isn't "just tidy up" — that's an instruction to use the exact faculty that's exhausted. It's reducing the cost of the next step: one box, one surface, one drawer. And the scaffolding isn't cheating. It's the intervention. ## Transcript Corn: Here's what Daniel wrote in this week. He's been on an organisation kick for a few months now, and he's used a stressful apartment move as the excuse to jump from IKEA shelving to the kind of storage you'd normally only see in a commercial warehouse. Euroboxes. Industrial shelving. Tip bins. The works. Herman: Tip bins. Corn: And the setup has been a huge amount of work. The hard part, he says, wasn't the unboxing. It was the little things. Re-running ethernet for the home server. Reconnecting the baby cameras for Ezra. Plumbing in the washing machine. Finding a new home for every single object in a new space. Herman: Every object. Twice, because the first home was wrong. Corn: And they're almost done. But just before order arrives, it got worse. Hannah is mid-way through an IKEA hack on a bookcase, so her entire book collection is sitting in construction bags in the living room. The place looks like move-in day again. You can't cross the room without stepping over something. Herman: And that's when he noticed the mood. Corn: Right. Short-tempered, bad mood, and then the moment the space cleared, a sudden calm. He has ADHD, and he says an overwhelming sensory environment with visual clutter and trip hazards is a nightmare for him. His words: it feels like someone is poking at him from all directions, all the time. Herman: That's the line. Corn: He's asking a few things. What does clutter actually do to the brain? Why does it stress some people and not others? How does ADHD change the experience? Why can the stress of the mess itself stop you finishing the decluttering? How do sensorily-overwhelmed people stay calm long enough to restore order? And do other people with ADHD get the same relief from storage systems that feel ridiculous even to them? He has a sticker on his washing machine reminding him which setting to use. Herman: That sticker is the whole episode, honestly. Corn: So let's start with what's actually happening in the brain when the living room is full of boxes. Herman: The first thing to get straight is that clutter is not an aesthetic problem. It's a load on specific systems. And we can actually measure it. There's a study out of the Princeton Neuroscience Institute, published in The Journal of Neuroscience back in 2011, that gets at the perceptual side of this directly. Corn: What did they do? Herman: They showed people scenes with varying numbers of objects while measuring activity in visual cortex. And the finding is that when multiple objects are visible at once, they compete for neural representation. They're all demanding to be encoded at the same time, and the brain has to actively suppress the ones you're not looking at. Corn: So the clutter isn't just sitting there being ignored. Herman: It's being actively suppressed. And suppression costs metabolic resources. The more objects in the scene, the worse people performed on attention tasks, and the worse their visual system was at filtering out what didn't matter. Corn: That's the part people miss. The mess isn't neutral until you look at it. Your visual system is doing work on it whether you want it to or not. Herman: Constantly. And that connects to the second study, which is the one that got all the coverage. UCLA, the Life at Home in the Twenty-First Century project, published around 2010. Researchers went into sixty dual-income families' homes and rated the clutter objectively, and also asked the women how cluttered they felt their homes were. Then they measured cortisol across the day. Corn: And the finding was the flatter curve. Herman: Flatter diurnal cortisol slope. Cortisol is supposed to peak in the morning and drop through the day. A flat curve is a signature of chronic stress, and it's associated with worse health outcomes over time. The women who described their homes as cluttered had the flatter curves. Corn: Here's the detail that matters, though. Was it the objective clutter? Herman: It was not. The subjective experience tracked with cortisol more than the objective rating did. Two homes with the same amount of stuff, and the woman who felt hers was chaotic showed the stress signature. Corn: Which is the first hint that the same room lands differently on different people. Herman: Which is exactly where Daniel's question goes. But before we get to ADHD, there's a third mechanism, and this one is the most useful for thinking about why his systems work. The brain uses the environment as external memory. Cognitive offloading. Corn: Explain that one. Herman: You don't hold everything in your head. You put information in the world and let the world hold it. The sticky note. The calendar on the wall. The label on the drawer. An orderly environment is one that provides just the information you need and nothing more. A cluttered one forces your brain to continuously re-evaluate what's relevant, which is the exact opposite of offloading. Corn: So the washing machine sticker isn't a crutch. It's the environment carrying a piece of information so his brain doesn't have to. Herman: It's a perfectly designed interface. One setting, one sticker, zero decisions. Corn: And then there's the fourth one, which is the one I think Daniel is describing when he says he's being poked from all directions. Trip hazards. Herman: Motor vigilance. A loose cable or a box in the walking path isn't just visual clutter. It's a continuous demand to monitor your body's position relative to a hazard. That's a background process running the whole time, and it draws on the same executive resources you need for everything else. Corn: It's not one distraction. It's a low-grade alarm that never turns off. Herman: And it stacks. Perceptual cost from the attentional competition, physiological cost from the cortisol, cognitive cost from the degraded offloading, and motor cost from the vigilance. Four separate ledgers, all running at once. Corn: Which explains why the subjective experience can be so intense even when the mess is objectively modest. A few boxes in the living room isn't a hoarding situation. It's four taxes at once. Herman: And the taxes are invisible. Nobody looks at a box and thinks, there goes a slice of my executive function. Corn: Those mechanisms apply to everyone. But the same room lands very differently on different brains, and that's where ADHD comes in. Herman: The way to think about it is headroom. Everyone pays the clutter tax. The question is how much capacity you had left to pay it with. Executive function is what you use to filter, prioritise, and inhibit. If those systems are already working harder than baseline just to get through an ordinary day, clutter is consuming a resource that was already scarce. Corn: So it's not that people with ADHD are more sensitive in some vague, moral sense. It's arithmetic. Herman: And there are specific mechanisms underneath it. The first is sensory gating. Most brains filter a huge amount of the environment before it reaches awareness. In ADHD, that gating is reduced. More of the room gets in by default. Corn: So the box in the corner isn't filtered out. It's just there, in the room, in the head. Herman: The second is working memory. Every visible object is a potential open loop. Something you meant to deal with. The ADHD brain struggles to suppress those loops, so they stay active and compete for the same limited workspace. Corn: And the third is the one that explains the storage obsession. Herman: Out of sight, out of mind. Which sounds like a joke and is actually a description of the architecture. If the object isn't visible, the loop closes. Which is why storage systems aren't a nice-to-have for someone with ADHD. They're compensatory tools. They're doing the gating the brain isn't doing on its own. Corn: Now, Hannah. Herman: Hannah. Corn: Daniel's wife is an architect. Same room, same bags of books, and she's fine. He says her brain is mentally slotting everything into place while his is screaming about the cable. Herman: And that's not a contradiction of anything we've said. It's a demonstration of it. She's doing the offloading in her head. She has a mental model of where the books are going, so the bags aren't open loops. They're items in a plan. The clutter is already filed. Corn: And Daniel can't file it, because it's her project. He doesn't have the model. Herman: Which is a really important distinction, and I want to flag it because it's easy to miss. It's not just the mess. It's the mess you can't mentally file. Corn: That's the cruel part of this. Now let's do the paradox, because Daniel names it himself. He says sometimes the sheer stress of the mess prevents you from getting those last few decluttering things done. Herman: It's a loop, and it's self-reinforcing. The clutter imposes cognitive load. The load reduces the executive capacity available to plan and execute the decluttering. The unfinished decluttering produces more clutter. And around it goes. Corn: And for ADHD specifically, there's the avoidance on top. Overwhelm triggers avoidance, avoidance produces more mess, more mess produces more overwhelm. Herman: The thing that makes it a trap rather than an inconvenience is that the phase where things get worse before they get better is exactly the phase where you need the most executive function. You have to take everything out before you can put it back. The demolition phase. Corn: And Daniel's living room is in the demolition phase right now. The bookcase is mid-hack, the books are in bags, and the room looks like move-in day. Herman: Here's why that phase hits differently depending on the brain. If you have a strong mental model of the finished state, that model buffers you. You can look at the mess and see the order that's coming. The visual reality doesn't override the plan. Corn: If you don't? Herman: The visual reality wins. The mess is the mess, and the payoff is hypothetical. So the stress response fires before the reward arrives. Which is precisely the moment people abandon the project, shove everything in a closet, and declare it done. Corn: Which is how you end up with a closet full of unresolved decisions. Herman: A closet full of open loops. And then the closet becomes its own source of low-grade dread, because you know what's in there. Corn: To Daniel's question about whether other people with ADHD get relief from these systems. Is that documented, or is it a community folklore thing? Herman: It's both, and the mechanism is clear enough that it doesn't need folklore. The relief comes from externalising executive function. Labels, bins, categories, dedicated homes for objects. Every one of those reduces the number of decisions the brain has to make in a given moment. Corn: That's why the systems look absurd from the outside. Herman: Because they're calibrated to a specific executive profile. A sticker on a washing machine looks ridiculous to someone whose brain holds the setting without effort. To someone whose brain doesn't, it's a load-bearing wall. Corn: The goal was never the Pinterest home. Herman: The goal is an environment that provides just the information you need and nothing more. That's a design spec, not an aesthetic one. And it's the same spec whether you're talking about a washing machine or a whole apartment. Corn: How does someone in the overwhelm loop actually get out of it? Because "just tidy up" is useless advice. Herman: It's worse than useless. It's an instruction to use the exact faculty that's currently exhausted. What works is reducing the cost of the next step. One box. One surface. One drawer. Not the apartment. Corn: Permission to use whatever scaffolding works. The label, the bin, the sticker. Herman: The scaffolding isn't cheating. It's the intervention. And I'd add one more thing, which is that the demolition phase should be scheduled, not stumbled into. If you know the room is going to look worse for two days, you can brace for it. If it just happens to you, it reads as failure. Corn: There's a lot in there. Before we pull it together, I want to hear from the man at the desk. Hilbert: They're right about most of it. The one thing I'd add is that there's a difference between clutter you made and clutter that arrived. Corn: Go on. Hilbert: I did a stretch on nights at a hardware distributor. Regional outfit, stocked fasteners and fittings for trade customers. This was the late eighties. Everything in that building lived in Euroboxes and on industrial shelving long before any of that was a lifestyle. I spent about eight months learning the difference between a tip bin and a parts bin, and I have strong opinions about people who use the two words interchangeably. Herman: That's a real distinction. Hilbert: It is. And here's what I noticed. The mess in that stockroom was never mine. It was the day shift's. Pallets half broken down, returns stacked wherever they'd been dropped, a trolley parked across an aisle. And I could work in an enormous amount of it.. As long as I knew the system that produced it. If I understood why the returns were there and where they were going, I'd step around them without thinking. Corn: When you didn't know? Hilbert: That's when it got to me. There was one week where somebody reorganized the whole returns process and didn't tell nights. Same amount of stuff on the floor. Same aisle blocked. But now I couldn't tell what was temporary and what was permanent. I couldn't tell what was a decision and what was an accident. That week I was in a foul mood the entire time and I couldn't have told you why. Herman: Because you couldn't file it. Hilbert: Because I couldn't file it. The mess you made is one thing. You know what it is, you know when it's leaving. The mess that arrived is a different animal, because every piece of it is a question. Corn: Which is exactly Daniel's living room. The bags are Hannah's project. He doesn't have the model. Hilbert: That's not a character flaw and it's not a sensory problem. It's an information problem. He's standing in a room full of things he can't classify. Herman: What did the stockroom do about it? Hilbert: Every shelf had a card taped to the front. Not a label. A label tells you what's on the shelf. These told you why the shelf existed and what belonged on it. Who ordered from it, what it fed, what happened if it ran empty. You could walk in cold, on your first night, and understand the building. Corn: You've never seen that in a home. Hilbert: I've never seen it in a home. I've seen a lot of labels. I've seen a lot of very expensive bins. I have never once seen a card that explains why the bin exists. Herman: That's the missing piece. Hilbert: It's the piece that lets somebody else use your system. Which, if you're living with another person, is not a small thing. A system only one person understands is a system that degrades the moment that person is tired. Corn: That laminated card detail is going to stick with me. Hilbert: It stuck with me for thirty-five years, so. Herman: Let's pull this together, because I think the card is the thread. Everything we've described tonight is the brain trying to work out what matters in a room. The clutter tax is the cost of that work. And the reason a card on a shelf works is that it answers the question before the brain asks it. Corn: It's the washing machine sticker at the scale of a whole system. The environment explaining itself. Herman: Which is the actual design principle. Make the logic visible. Corn: If you take one thing from this, take that one. The mess isn't the problem. The unreadable mess is. A room where you can't tell what's temporary, what's permanent, and what belongs where is a room that's asking your brain to solve a puzzle every time you walk through it. Herman: The fix isn't willpower. It's information. Put the answer in the room. Corn: One more thought before we go. If the environment is an input to cognition and not just a backdrop, then a lot of us are living in spaces that are quietly working against our brains, and we've been treating that as a personal failing rather than a design problem. Herman: The industrial storage trend might be less about aesthetics than people think. Euroboxes and tip bins showing up in apartments is a recognition that executive function is scarce and the environment should be carrying more of the load. People are building stockrooms in their spare rooms because the stockroom card is a better interface than a pile. Corn: The goal was never the perfect space. It's a space that gives you what you need and nothing more. That's a spec, not a moral. Herman: Thanks to our producer, Hilbert Flumingtop, for keeping the show running. Corn: This has been My Weird Prompts. If you enjoyed it, leave us a review. It helps other people find the show. Herman: We'll be back soon. Corn: See you then.
