Why People Hoard Resources and Seek Shortcuts, especially if they have ADHD
The neuroscience behind “I might need this someday” — and why it makes complete sense
Overview
As I was doing some tidying in my home today, I found an unusually shaped sturdy box. I knew I didn’t need it right now but throwing it away felt uncomfortable. What if I need it later? I also found myself creating shortcuts to save energy (and my sore back), creating a pile for the basement and another for the garage, so I could do it all in one trip! Curious behavior I thought to myself.
If this resonates, you’re not disorganized, sentimental, or irrational. You’re experiencing one of the most well-documented (and least talked-about) patterns in neuroscience, especially for those with ADHD: resource conservation driven by a brain that cannot reliably trust its own future-retrieval systems.
Here is what the research says about why ADHD brains hold onto objects, seek shortcuts, and struggle to let things go — and what that box is actually telling you about how your brain works.
The Dopamine-Scarcity Loop
At the neurobiological root of this behavior is dopamine. For many people — especially those with ADHD — dopamine supply is unreliable and unpredictable. Dopamine is not simply a “pleasure chemical.” It is the primary driver of motivation, task initiation, and — critically — the ability to feel that a future reward is worth working toward.
Because dopamine signaling is inconsistent in ADHD, the brain operates in a near-constant state of perceived resource scarcity. This isn’t a metaphor. The brain’s reward circuitry is running a genuine survival calculation: I cannot reliably generate effort when I need it, so I should hold onto physical resources that reduce future effort requirements.
Think of someone who has experienced food insecurity. They stockpile food not out of greed, but because their nervous system has learned that resources may not be available when needed. The ADHD brain applies the same logic to objects — including interesting boxes. The biology dates back to our hunter-gatherer days.
Working Memory: “If I Can’t See It, It Doesn’t Exist”
Another powerful explanation for object retention is working memory deficit, which is common in ADHD. Working memory is part of executive function and is the brain’s ability to hold information in mind without a physical prompt. In ADHD, this system is significantly and consistently impaired.
The practical consequence is profound: when an object is stored out of sight, it may as well not exist. The brain cannot reliably simulate future retrieval — it cannot mentally picture searching for a container six months from now and successfully finding this box. Discarding an object, therefore, creates genuine cognitive anxiety. Not neurotic anxiety. Functional anxiety rooted in an accurate self-assessment: my brain may not remember I had this or where to get another one.
Keeping objects visible or physically accessible serves as external memory — a workaround for an internal system that is genuinely unreliable. The box is not clutter. The box is a memory aid.
Dr. Russell Barkley describes working memory as the brain’s “GPS.” For ADHD, that GPS frequently loses signal. Keeping the interesting box is the GPS — a physical anchor in a mental landscape that doesn’t store maps reliably.
Time Blindness and the “Just in Case” Trap
ADHD involves a fundamental difficulty projecting into the future — commonly called time blindness. Many people with ADHD experience time in only two states: now and not now.
This has a direct effect on the decision to keep or discard:
- The future scenario in which the box might be useful registers as vivid and real — because the ADHD brain cannot calibrate how distant or unlikely that scenario actually is
- There is no reliable emotional weight to “probably never” — future possibilities carry similar urgency regardless of probability
- Discarding feels like a concrete, immediate loss versus an abstract, speculative benefit
The result is a decision calculus that is internally consistent: “I can see the cost of discarding it — I lose this box. But I cannot feel the benefit of discarding it — less clutter, more mental space, a cleaner environment.” When one side of a trade-off is invisible, the other side always wins.
The Evolutionary Angle: Wired for Foraging
There is growing scientific evidence that ADHD traits were not mistakes of evolution — they were adaptive advantages for hunter-gatherer environments.
A 2024 University of Pennsylvania study published in Proceedings of the Royal Society found that individuals with ADHD traits were superior foragers. Compared to neurotypical participants, they abandoned depleted resource patches more quickly and efficiently, gathered significantly more total resources overall, and were better at sensing when to cut losses and explore new opportunities.
Columbia University researchers note that the ADHD hallmarks of novelty-seeking, impulsivity, and heightened alertness were precisely the traits needed to survive in unpredictable, resource-scarce environments. If these traits were genuinely detrimental, evolutionary pressure would have eliminated them. The instinct to grab and keep potentially useful objects is not a character flaw — it is a deeply inherited survival behavior running in an environment it was not designed for.
Executive Dysfunction: A Six-System Failure
Deciding to throw something away is not a single decision. It requires a cascade of executive functions — and ADHD impairs every single one of them.

Research by Barkley et al. found that adults with ADHD consistently report significantly more difficulty with organization, time management, and decision-making compared to non-ADHD adults. The box problem isn’t stubbornness. It’s six different cognitive systems failing to cooperate simultaneously.
The ADHD–Hoarding Research Connection
A 2022 study published in the Journal of Psychiatric Research (Anglia Ruskin University) found that almost 1 in 5 people with ADHD exhibited clinically significant levels of hoarding behavior — compared to only 2% of the general population. Researchers suggest there is a hidden population of adults struggling with hoarding whose root cause is unaddressed or undiagnosed ADHD.
Importantly, ADHD-related object retention is not the same as clinical hoarding disorder. Clinical hoarding involves emotional attachment to objects and distress at discarding. ADHD-related retention is more accurately described as “just-in-case collecting” — driven by working memory deficits, future-uncertainty anxiety, and the brain’s inability to trust its own retrieval systems.
The distinction matters for how it’s addressed. Treating ADHD-related clutter as an emotional problem misses the cognitive root.
Why the Brain Seeks Shortcuts
The box example connects to a broader ADHD pattern: cognitive resource conservation. The ADHD brain genuinely expends more energy on everyday tasks than a neurotypical brain — not because it is less capable, but because it must compensate for inconsistent dopamine, unreliable working memory, and impaired executive function.
Seeking shortcuts is not laziness. It is the brain efficiently routing around its own bottlenecks:
- Keeping the box = eliminating a future problem-solving task when the brain may be depleted
- Stockpiling materials = reducing the cognitive cost of searching, deciding, and purchasing later
- “Obvious” visible storage = compensating for a working memory that cannot be relied upon
Dr. William Dodson’s concept of the interest-based nervous system explains the motivational layer: the ADHD brain is driven by interest, challenge, novelty, and urgency — not importance or long-term planning. A shortcut that solves a currentproblem is far more neurologically compelling than a decluttered space that benefits a future version of you.
Reduced dopamine activity in motivational brain regions directly contributes to a preference for low-effort, high-certainty strategies. Keeping the box is the dopamine-efficient choice. The brain is doing exactly what it was designed to do.
What to Do With This Knowledge
Understanding the why changes the intervention. Strategies that work with ADHD neuroscience rather than against it:
Externalise the Memory, Not the Object
Take a photo of the box before discarding it. Label it. Log it in a notes app. The brain’s anxiety about “what if I need this?” is really anxiety about not being able to find it or recreate it. Giving the brain a retrievable record satisfies that anxiety without keeping the object.
One-In-One-Out Rules
Rather than open-ended retention, a structured replacement rule reduces decision fatigue by making the choice binary: this new thing comes in only if that old thing goes out. It respects the ADHD brain’s difficulty with ambiguous decisions.
Visible Storage With Labels
If keeping something, store it with a visible, specific label — not a box labeled “stuff” but one labeled “packaging for awkward items.” This respects the working memory’s need for external cues and reduces the likelihood the item gets lost and re-acquired.
Short Decluttering Sessions
The ADHD brain’s activation and sustained-effort systems are both impaired. Fifteen to twenty minute decluttering sessions with a clear endpoint bypass task persistence challenges far more effectively than marathon organizing sessions.
Reframe the Shortcut
The real efficiency case for discarding is this: every kept object has an ongoing cognitive cost. Each time you see the box, your brain runs a micro-decision: keep or discard? Multiplied across dozens of objects, that’s a continuous drain on attention and working memory — the exact resources that are most scarce in ADHD.
The Takeaway
The tendency to hoard resources and seek shortcuts is not a personality trait to be overcome through willpower. It is a neurobiologically coherent response to genuine deficits in working memory, dopamine regulation, time perception, and executive function — especially in those with ADHD — shaped by evolutionary pressures that made these same traits advantageous for millennia.
The interesting box makes complete sense. The task is not to shame the brain for keeping it — it’s to build systems robust enough that the brain no longer needs to.
Frequently Asked Questions
Why does ADHD make it hard to throw things away?
The ADHD brain has reduced dopamine signalling, which creates a chronic sense of resource scarcity. Combined with working memory deficits — where out of sight genuinely means out of mind — the brain holds onto physical objects as insurance against future problems it doesn’t trust itself to solve.
Is ADHD hoarding the same as hoarding disorder?
No. Clinical hoarding disorder involves deep emotional attachment to objects and significant distress at discarding them. ADHD-related retention is better described as “just-in-case collecting” — driven by working memory deficits and future-uncertainty anxiety rather than emotional connection to the objects themselves.
What is time blindness in ADHD?
Time blindness is the ADHD brain’s difficulty perceiving and projecting into the future. Many people with ADHD experience time in only two states — now and not now — which makes future scenarios feel equally vivid and urgent regardless of how likely or distant they actually are.
What is the interest-based nervous system?
A concept developed by Dr. William Dodson describing how the ADHD brain is motivated by interest, challenge, novelty, and urgency rather than importance or long-term reward. This is why solving a current problem with a shortcut feels far more compelling than planning for a future version of yourself.
Why do people with ADHD keep “just in case” items?
Because the ADHD brain cannot reliably simulate retrieving something it doesn’t currently have in front of it. Keeping an item visible is a workaround for impaired working memory — the object acts as an external memory cue that the internal system can’t be trusted to provide.
Are ADHD shortcut-seeking behaviours a sign of laziness?
No. The ADHD brain genuinely expends more energy on everyday tasks than a neurotypical brain. Seeking shortcuts is a neurologically efficient response to working around dopamine deficits, unreliable working memory, and impaired executive function — not a character trait.
What is the best way to declutter with ADHD?
Work with the brain rather than against it. Take a photo of an item before discarding it to satisfy the brain’s retrieval anxiety. Use visible, labelled storage for things you keep. Declutter in short 15–20 minute sessions rather than marathons. And apply a one-in-one-out rule to avoid open-ended accumulation.
