Why is decluttering so hard? There's a Nobel Prize about it
Letting go of your stuff genuinely hurts, and there's a named, Nobel-winning reason why. Once you know the mechanism, you can stop fighting it and route around it instead.
You pick up the old gadget. You know you don’t use it. You haven’t touched it in three years, you’d never buy it again today, and you can see perfectly well that it’s taking up space you want back.
And still, something in your chest goes tight and says no, not that one.
That moment is the whole reason decluttering is hard, and I want to tell you exactly what’s happening in it, because once you know, you’ll stop thinking you’re broken.
The endowment effect (and the famous coffee mug)
There’s a real, named, Nobel-Prize-winning reason it physically hurts to let go of your things. It’s called the endowment effect, identified by the economist Richard Thaler alongside the psychologists Daniel Kahneman and Amos Tversky. The finding is wonderfully simple: the moment you own something, you value it more than you would if you didn’t own it. Even if it’s worthless. Even if you’d never buy it again.
There’s a famous experiment where researchers gave people a plain coffee mug and then asked what they’d sell it for. The owners wanted far more money than other people were willing to pay for the exact same mug. Nothing about the mug had changed. Only who owned it.
And here’s the part that matters most for us: the effect isn’t really about how much you love the thing. It’s about how much it hurts to give it up. We’re wired to feel a loss much more sharply than we feel an equivalent gain. So when you go to bin something and feel that weird pang of “noooo”, the pang is not a sign you need it. It’s loss aversion doing its ancient, slightly daft job.
Knowing this is genuinely freeing. The tight feeling isn’t wisdom. It’s a reflex, the same reflex that makes everyone overvalue their own clutter. You are not uniquely sentimental or uniquely rubbish at this. You are a human being with a human brain that hates letting go of mugs.
So we’re not going to fight the reflex head on. Nobody wins that. We’re going to route around it.
Clutter is delayed decisions, and that’s why it piles up
The American organiser Barbara Hemphill has a line she liked enough to trademark: clutter is postponed decisions. I think of it as clutter is just delayed decisions, and the moment that clicked for me, everything made sense.
Look at any pile in your home and it’s true. The drawer of mystery cables is a stack of decisions you haven’t made. The chair buried in clothes: decisions. The loft full of boxes: an enormous, dusty backlog of decisions, some of them years old. Clutter isn’t really stuff. It’s unmade decisions wearing the disguise of stuff.
Which leads to the kindest realisation I know about this whole subject: we don’t have piles because we’re lazy or dirty or broken. We have piles because decisions are genuinely expensive for our brains, so they pile up. That isn’t a character flaw, it’s literally the mechanism. Of course you’re surrounded by clutter. You’re surrounded by every decision you found too hard to make in the moment, and that’s allowed. That’s just how mess happens.
The twist: postpone on purpose
Here’s where I part company with most advice. The usual line after “clutter is postponed decisions” is so stop postponing, decide everything immediately! And for brains like ours that’s a trap, because being forced to decide everything on the spot is exactly what makes us freeze.
So do something cleverer. Postpone deliberately, with a deadline, instead of passively, by accident, forever.
That’s the entire difference between a pile and a plan. A postponed decision left lying around is clutter. A postponed decision with a date written on it is a plan, waiting for a calmer, stronger version of you on a day you’ve actually scheduled. Same delay, completely different thing.
In the book this is the Procrastabox, and it’s the single most-used idea in the method. One box, labelled, with a revisit date on it. Anything you can’t face deciding goes in, no decision required, and you keep moving. When the date arrives, you revisit, and you’ll find a load of it is much easier to part with now there’s distance between you and it.
The pro move: tape it shut and date it. If the date comes round and you never once needed to open it to get something out, well. You have your answer, don’t you. You didn’t miss any of it.
One warning, because I know us: the box is a staging system, not a new place to hoard. One Procrastabox, with a date. If a second one appears, and then a little annexe forms in the spare room, you’ve invented a new flavour of clutter. The deferral is a kindness, not a loophole.
”But it was expensive”
This is the second great wall, and it has a name too: the sunk cost fallacy.
The money is already gone. It’s spent. Keeping the unused thing in the cupboard doesn’t recover a single penny. It just means you paid money and you’re now also paying with space, every single day, indefinitely.
The cost happened in the past. The only real question is whether the thing earns its place now, going forward. Keeping something you don’t use in order to justify what you spent is like ordering a second bad meal because you didn’t enjoy the first. Let it go. The money was spent either way, so at least reclaim the space.
”But I might need it one day”
For this one there’s a tool I love, the 20/20 rule, from The Minimalists. If you could replace the item for under about £20, in under 20 minutes, from somewhere near you, you’re allowed to let it go.
Because you’re not really keeping the object. You’re keeping a hedge against a small, unlikely inconvenience. Weigh “this thing cluttering my space every day for years” against “the slim chance I nip out and rebuy a £6 thing once”, and the maths is usually obvious. (This is for cheap, replaceable stuff, obviously. Not your passport or your nan’s ring.)
And here’s the reframe that really melts the fear for people like us. Let’s be honest: the one thing we are undeniably excellent at is buying. Researching, comparing, hunting down the right one, clicking the button. It’s half the reason we’re in this mess. So put that skill to work as a safety net. On the rare day you let something go and genuinely need it again, you are extremely well equipped to get another one, fast, and probably a better version. The door doesn’t lock behind you.
Two sayings sit next to that rule, and I mutter both constantly while I sort. There’s no such thing as someday. “I’ll use it someday”, “I’ll fix it someday”: someday isn’t a real day, it never lands in the diary, and with no plan and no date it’s just “never” wearing a nicer coat. And the flip side: use it or lose it. If a thing earns its keep then use it. Wear the good jumper, light the nice candle, play the record. If you’re not going to, be honest and let it go to someone who will. A thing you neither use nor will use isn’t being kept, it’s being stored, and storage isn’t a relationship with an object. It’s a holding pen for a decision.
The sentimental things (do them last)
Marie Kondo’s pace isn’t for everyone, and it certainly isn’t the pace this method uses, but two of her ideas are gold here.
Do sentimental items last. By the time you reach them you’ll have made a hundred smaller decisions and built the muscle, so the hard ones land easier. Do not start your decluttering with the photo albums. You will never recover.
Let things go with gratitude. Instead of “I’m throwing this away”, which registers as pure loss, thank the item for what it gave you, and then let it go. It sounds soft and it works, precisely because it reframes the moment from losing something into honouring something. You’re not binning the memory. The memory lives in you, not in the object. And if it helps, photograph the thing before it goes: the photo holds the memory, your cupboard gets the space.
The half-finished project
One more, because almost everyone has one. The half-knitted jumper. The part-built model. The “I’ll get back to it” gathering dust.
We keep these out of guilt, because letting go feels like admitting we failed them. Flip it round: a project that’s sat dormant for a year hasn’t been waiting for you. The dormancy was the decision, you just hadn’t said it out loud.
And here’s the freeing bit. Letting it go is a way of finishing it. Scrapping a project closes it as surely as completing it would, and it hands back the space, the materials, and above all the low hum of guilt it generated every time you walked past. Done and gone both clear the desk. You’re allowed to choose gone.
Try this week (just these two)
- Start a Procrastabox. One box, labelled, with a revisit date a month from now. Put in the first three “ugh, I can’t decide” things you spot. Three things parked, pressure gone.
- Run the 20/20 rule once. Find one “might need it” item and ask honestly whether you could replace it for under £20 in under 20 minutes. If yes, into the charity box. Just one. Notice how little you miss it.
Decluttering is hard because your brain is doing something normal and ancient, not because you’re weak. Stop fighting the reflex and start routing around it, and the whole thing gets a great deal kinder.
The whole method, if you want it
This guide is the taster. The free printable system gives you the sheets to work round your home one small spot at a time, free forever. The full method, including the four-stage Tap Cycle and the rule that keeps a sorted home sorted, is in the book, Turn Down the Tap. If decisions are especially expensive for your brain, start with how to declutter with ADHD. And if your clutter has a fandom, there’s a bolt-on guide that speaks your dialect, whether that’s LEGO, Warhammer, vinyl, trading cards, action figures or bikes.
No shame. Progress, not perfection. One decision at a time.
