Leaks and Deposits

Here is the pattern. One partner gradually becomes the default organiser. They track the school calendar, remember the in-laws’ birthdays, notice when the dishwasher tablets are running low, and mentally hold the shape of the household so everyone else can move through it without thinking. The other partner does not seize this role — it just drifts to them. And because nobody is keeping score, the person benefiting from it barely notices. There is no single moment of unfairness. Just a slow, invisible transfer.

For a while it works. The organiser copes. They might even feel quietly competent about it. But something is being drawn down. Goodwill. Patience. The feeling that someone has your back. And because the drawdown happens in small, deniable increments — not one dramatic withdrawal but a thousand tiny ones — the organiser does not flag it until something breaks. A forgotten anniversary. A dismissed request. A minor logistical failure that, on its own, is trivial — but lands on a balance that has been running on fumes for months.

The blow-up seems disproportionate from the outside. “It was just about the bins.” But it was never about the bins. It was about a shared resource that had been silently depleted while both people looked the other way.

I call these dynamics leaks and deposits. And the framework that explains them is one of the most useful in systems thinking.

What Is a Commons?

A commons is any shared resource that multiple people draw from. The concept comes from ecology: a shared grazing pasture, a fishery, a water table. Everyone benefits from the resource. Everyone has access. And the problem — the structural, predictable, almost mathematical problem — is that each person’s incentive to take from the resource is stronger than their incentive to protect it.

The term “tragedy of the commons” was formalised in the 1960s, but the dynamic is ancient. It describes what happens when a shared resource has weak feedback between its condition and the decisions people make about using it. Everyone draws. Nobody monitors. The resource degrades. And by the time anyone notices, the damage is severe.

Now apply this to the systems you actually live in.

Relationships have commons. Families have commons. Your own internal life has commons. And they get depleted by the exact same mechanism that kills fisheries and drains aquifers — not through malice, but through a structural gap between individual benefit and collective cost.

The core principle: A commons is a shared resource everyone draws from but nobody explicitly manages. In relationships and families, the commons include goodwill, attention, patience, household functioning, sexual connection, and mental bandwidth. The “tragedy” is not selfishness — it is weak feedback. People overuse the resource not because they are careless, but because the resource gives no clear signal that it is running low until it collapses.

Goodwill is like oxygen in a room. You do not notice it until it is thin.

How the Commons Gets Depleted

The mechanism is the same whether you are talking about a marriage, a family, a friendship, or your own internal reserves. Four features make a commons vulnerable to overuse.

1. The immediate benefit is private

When one person offloads a task, avoids a difficult conversation, or takes without reciprocating, the benefit lands on them immediately. They feel relieved, unburdened, or simply comfortable. That benefit is concrete and felt right now.

2. The cost is delayed and shared

The cost — the drawdown of goodwill, the erosion of trust, the slow depletion of someone else’s bandwidth — does not land on the person who took. It disperses across the relationship. It shows up later, in a different form, often in a way that seems unconnected to the original withdrawal. The person who skipped the conversation does not experience the cost. The person who carried it does — weeks later, as fatigue, as resentment, as a shorter fuse.

3. Feedback is weak

There is no dashboard. No meter that reads “goodwill at 30 per cent.” No alarm that sounds when patience is critically low. The signals that do exist — a clipped tone, a sigh, a slight withdrawal — are ambiguous enough to be ignored, explained away, or attributed to something else entirely. By the time the feedback is unmistakable (a fight, a shutdown, a threat to leave), the resource has already been severely depleted.

4. Overuse becomes normal

Because each individual withdrawal is small and the cost is invisible, the pattern of overuse becomes the baseline. It stops looking like overuse and starts looking like “just how things are.” The organiser has always managed the logistics. The calm parent has always absorbed the household stress. The patient friend has always been available. Nobody decided this was fair. It simply became the operating norm — and norms are nearly invisible to the people living inside them.

These four features interact to produce a predictable outcome: the resource degrades slowly, nobody notices until it is critically low, and then a small trigger produces a response that seems wildly disproportionate. But the response is not disproportionate. It is proportionate to the accumulated depletion. The trigger was just the moment the balance finally went to zero.

Example 1 — The Emotional Labour Commons

Step 1: One person’s attention and emotional capacity becomes a shared resource. They are the one who remembers, who notices, who initiates difficult conversations, who tracks the emotional temperature of the household. This starts naturally — they are good at it, or they care more, or they simply got there first.

Step 2: Others begin to offload. Not deliberately. Not maliciously. But because someone is already handling it, there is less pressure to develop the skill yourself. The partner stops tracking when the kids seem off. The children learn that one parent is the one who “gets it.” Tasks flow toward the person who will catch them.

Step 3: The carrier does not complain early. Because each individual request is small. Because saying “I need you to notice things” sounds petty. Because they have internalised the role as part of their identity. The feedback signal stays buried.

Step 4: Fatigue and resentment build. The carrier begins to feel taken for granted, but the feeling is diffuse and hard to articulate. It shows up as irritability, withdrawal from intimacy, a quiet bitterness that leaks into unrelated interactions.

Step 5: A small incident triggers a blow-up. The partner forgets to ask about a medical appointment. The child dismisses a reminder with an eye-roll. The response is intense — disproportionate to the trigger, entirely proportionate to the accumulated depletion.

Step 6: Trust drops. The blow-up itself becomes a withdrawal from the commons. Now the partner feels attacked. The children feel confused. The repair load increases. And the commons — already depleted — takes another hit.

Example 2 — The Attention Commons in a Family

Step 1: One parent’s calm bandwidth becomes the family’s shared resource. They are the regulated one. The steady one. The person whose composure holds the household together when things get chaotic.

Step 2: Children increase their demands. The other parent defaults to them for decisions, conflict resolution, and emotional regulation. “Ask Mum” or “Wait for Dad” becomes the household reflex. Every request is individually reasonable. Collectively, they are draining one person’s nervous system at an unsustainable rate.

Step 3: The calm parent keeps coping. Because that is what they do. Because pausing to say “I am depleted” feels selfish when the children need something right now. Because the alternative — letting things be messy — triggers their own anxiety.

Step 4: Irritability and shutdown appear. The calm parent starts snapping at minor provocations. They withdraw into their phone, into work, into any activity that does not require them to be emotionally available. The family notices the withdrawal but not its cause.

Step 5: A minor misbehaviour from a child lands on an empty tank. The response is yelling — out of character, alarming, and immediately followed by guilt. The child is confused. The partner is confused. The calm parent is ashamed.

Step 6: Guilt and repair become additional withdrawals from the commons. Now the depleted parent is carrying the emotional weight of the blow-up on top of the original depletion. The repair effort — apologies, reassurance, self-recrimination — drains the resource further. A vicious cycle establishes itself.

The Common Misread

When a commons collapses — when the blow-up happens, when the resentment surfaces, when someone finally says “I cannot do this any more” — the instinctive response is to treat it as a personality problem.

“She overreacts.” “He never notices anything.” “She is too controlling.” “He is emotionally lazy.”

These framings feel accurate because they match what is visible: one person reacting intensely, another person seeming oblivious. But they miss the structure underneath. The “overreaction” is not a personality flaw. It is the predictable result of a shared resource being drawn down without feedback or limits. The “obliviousness” is not a character defect. It is the predictable result of a system where the cost of withdrawal is invisible to the person withdrawing.

Treating a structural problem as a personality problem does two things, both harmful. First, it concentrates blame on one person, which makes them feel more alone and more depleted — an additional withdrawal from an already-empty commons. Second, it prevents anyone from seeing the actual mechanism, which means no structural change occurs, and the cycle continues.

The Structural Miss

This is not a communication problem. Communication skills help, but they do not solve a structural deficit. You can communicate beautifully about a resource that has no rules, no monitoring, and no recovery protocol — and it will still collapse. The structure has to change.

Three Levers That Protect the Commons

Systems thinking offers three structural interventions. None of them require anyone to become a different person. They require the system to operate differently.

Lever 1: Make the Resource Visible

You cannot manage what you cannot see. The first step is to name the commons — explicitly, out loud, in shared language. “Our goodwill is a shared resource.” “My patience is not infinite — it is a pool that gets drained and needs refilling.” “The household runs on someone’s attention, and right now that someone is always me.”

Naming the commons sounds simple, but it is genuinely powerful. It takes something that was invisible — an ambient condition that everyone relied on but nobody acknowledged — and makes it concrete. It gives the resource a name and therefore makes it discussable.

Practical step: For seven days, track every withdrawal and deposit you notice. A withdrawal is anything that takes from the shared resource: offloading a task, not following through, taking patience for granted, consuming someone’s attention without reciprocating. A deposit is anything that replenishes it: taking initiative, expressing gratitude, handling something without being asked, protecting someone else’s bandwidth. You do not need to share this tracking. You just need to see the pattern.

Lever 2: Install Fast Feedback

The tragedy of the commons is fundamentally a feedback problem. The resource degrades because the people using it do not get clear, timely information about its condition. By the time they notice, collapse is imminent.

The intervention is to create a feedback loop that is faster than crisis. A weekly check-in with one question: “What drained you this week?” Not “how are you feeling” — that is too vague. Not “what can I do better” — that puts the burden of solution on the person who is already depleted. Just: what drained you. Specific, concrete, recent.

This question does two things. It surfaces information that would otherwise stay buried until it exploded. And it communicates that the resource matters — that someone is paying attention to its condition, not just consuming it.

Lever 3: Agree on Rules of Use

Open-access resources always degrade. The solution is not to privatise the commons — that kills the relationship. The solution is to agree on rules that keep the resource sustainable.

These rules feel mechanical. They are supposed to. Relationships fail not because people lack love but because they lack structure. Love without structure is just goodwill waiting to be depleted.

Practical Tool

The Commons Agreement

  1. Choose one commons. Do not try to fix everything. Pick the shared resource that is most depleted right now. Goodwill? Patience? Household bandwidth? Sexual connection? Emotional availability? Name it specifically.
  2. List the withdrawals. What are the concrete actions, habits, or defaults that drain this resource? Be specific: “Defaulting to me for all school logistics” is useful. “Not pulling your weight” is not. Aim for five to eight specific withdrawals.
  3. List the deposits. What are the concrete actions that replenish this resource? Again, specific: “Handling the morning routine without being asked” is useful. “Being more supportive” is not. Aim for five to eight specific deposits.
  4. Identify red zone signs. What are the early warning signals that this commons is critically low? Not the blow-up — the signals that come before the blow-up. Withdrawal? Sarcasm? Shortened responses? Loss of interest in connection? Name three to four red zone signs that both people agree to watch for.
  5. Agree on rules in the red zone. When the red zone signs appear, what happens? Who does what differently? What gets temporarily redistributed? What gets paused? Write it down. Not as a contract — as a shared understanding that both people helped create.
  6. Review weekly for four weeks. The agreement is a prototype, not a permanent law. Check in weekly: What worked? What didn’t? What needs adjusting? After four weeks, the useful parts will have become habits and the rest can be revised.
Clinical Illustration

A couple came in after what they described as a “ridiculous” argument about grocery shopping. She had asked him to pick up specific items. He came back with substitutes. She lost it. He was baffled. “It is just groceries.”

When we mapped the commons, the picture was different. She was carrying the household’s cognitive load — meal planning, children’s schedules, medical appointments, gift buying, home maintenance tracking. The grocery list was not just a list. It was one more output of a system that she ran alone. The substitutes were not just wrong items. They were evidence that the list — and by extension, the enormous mental effort behind it — did not matter enough to follow precisely.

He was not careless. He genuinely had not seen the commons. Once it was named — once the cognitive load became a visible, shared resource rather than an invisible background process — he could engage with it structurally. They built a commons agreement around household planning. Not a chore chart. A redesign of who held what, with minimum deposits and red zone protocols. The fights about groceries stopped. Not because they communicated better, but because the structure changed.

The Internal Commons

So far, I have been talking about interpersonal commons — shared resources between people. But the framework applies just as powerfully inside a single mind.

Your attention is a commons that every demand in your life draws from. Your patience is a commons that every frustration depletes. Your emotional bandwidth is a commons that every relationship, every worry, every unfinished task consumes. And the tragedy-of-the-commons mechanism operates identically: each individual demand seems small, the cost is delayed and diffuse, feedback is weak, and overuse becomes normal until you collapse.

Burnout is a tragedy of the internal commons. It is not caused by one overwhelming demand. It is caused by dozens of individually reasonable demands drawing from the same pool with no rules, no monitoring, and no recovery protocol. Each commitment, each obligation, each “yes” is a withdrawal. And because each one is small, you do not notice the depletion until you are running on empty and a minor trigger — a slow internet connection, a child’s question, a colleague’s email — produces a reaction that shocks even you.

The three levers work internally too. Make the resource visible: track what drains your bandwidth for a week. Install fast feedback: check in with yourself daily, not monthly. Agree on rules of use: set minimum deposits (recovery, rest, activities that replenish) and maximum withdrawals (a cap on commitments, a practice of saying no before the tank is empty rather than after).

Short-Term Relief, Long-Term Cost

Every time someone takes from a commons without depositing, they get short-term relief. The task is offloaded. The conversation is avoided. The effort is saved. That relief is real and immediate.

But the cost is also real — just delayed. The relationship gets a little thinner. The trust drops a fraction. The person carrying the load gets a little more tired and a little more bitter. And because the cost is delayed and diffuse, the person who benefited from the withdrawal never connects their short-term relief to the long-term degradation.

This is the fundamental maths of the commons: short-term relief, long-term cost. Every systems archetype in this series comes back to some version of this trade-off. The question is never whether the cost will arrive. It is whether you will see it in time to do something about it.

The commons does not need heroic effort. It does not need anyone to become a fundamentally different person. It needs visibility, feedback, and agreements. It needs people to see the resource they share, track its condition, and commit to rules that keep it sustainable.

That is not romantic. But it is the difference between relationships that deplete and relationships that endure.

Series connection: The commons dynamic often interacts with eroding goals — when the shared resource degrades, people lower their standards for what “good enough” looks like, which accelerates the decline. For how that mechanism works, see Post 9: The Slow Slide — Eroding Goals.

If you recognise the commons dynamic in your relationship, your family, or your own internal reserves — and you want help building the visibility, feedback, and agreements that protect the resource — that is exactly what we work on in therapy. Not blame. Not personality overhauls. Structural change that sticks.
