The mental load: why couples carry different work

In the therapy room, I hear a version of this exchange all the time. One partner says: "I do the school run, I cook three nights a week, and I do the washing. I don't understand why you say you do everything."

The other says: "I have to remember when the school trip is, check whether we have food for dinner, notice the washing needs doing, arrange the childcare, remember the birthday present, and then ask you to do your share."

Both of them are telling the truth. They're just describing two different kinds of work, and only one of those kinds tends to get counted.

Two kinds of labour

Sociologist Allison Daminger's 2019 study in the American Sociological Review, based on interviews with 70 people from 35 couples, breaks what's often called the "mental load" into four distinct stages: anticipating what needs to be done, identifying the options for addressing it, deciding between them, and monitoring whether it's actually been done.

Her research found that even among couples who divided visible, physical tasks fairly evenly, the anticipating and monitoring stages still fell overwhelmingly to one partner. That work rarely looks like work. It happens in the car, in the shower, at 2 am, and it's almost never visible to the partner who isn't doing it.

Two different scorecards

This is often why the same household can produce two honest but conflicting accounts of who does what.

The partner who sees things as fair tends to count the tasks they complete, while the partner who feels overloaded notices the work of identifying and organising those tasks in the first place.

The partner who sees things as fair sees a task once it needs doing, while the partner who feels overloaded has already anticipated what will be needed later.

The partner who sees things as fair completes a task when asked, while the partner who feels overloaded carries the responsibility for remembering it and delegating it.

The partner who sees things as fair considers a finished task "done", while the partner who feels overloaded is still monitoring whether the whole responsibility has actually been handled.

The partner who sees things as fair feels they are contributing, while the partner who feels overloaded feels they are managing both the work and the person doing it.

What the wider research shows

Daminger's findings aren't an outlier. A 2019 study by Ciciolla and Luthar in Sex Roles, surveying 393 partnered mothers in the US, found that feeling solely responsible for organising family schedules and household order, particularly for children's emotional adjustment, was associated with poorer personal wellbeing and lower relationship satisfaction.

More recently, a 2026 study in Women & Therapy by Palmwood and Liss developed a Mental Load Scale across three separate dimensions: invisible burden, logistical responsibility, and emotional labour. Across 569 adults in cohabiting relationships, higher scores on all three were linked to poorer mental health and relationship outcomes.

A further 2026 study in Personality and Social Psychology Bulletin by Klein, Ascigil, Oschatz, and Kahalon examined whether mental load mattered for satisfaction independently of housework itself. Across two studies, including data from 156 couples, partners reported greater relationship satisfaction when mental load, and emotional labour in particular, was shared more evenly, regardless of how the physical chores were split.

Why it's hard to see from the other side

One idea I find useful in session is that the partner carrying more of the mental load isn't just carrying more tasks. They're carrying the responsibility of making sure nothing gets missed, which is a different kind of weight.

The other partner, meanwhile, often sees their own contributions clearly, because doing a task is visible by definition, while the organising, anticipating and monitoring that happened before and after it stays invisible to them.

Neither partner is lying about their experience. They're each describing a different layer of the same system, and only one of those layers shows up on a to-do list.

A different question to ask

Instead of asking who does more, it's often more useful to ask who owns a given responsibility from beginning to end. Take something like booking a child's medical appointment: who notices it's needed, who finds the details and books it, who arranges transport or childcare around it, who remembers it on the day, and who follows up afterwards? Looked at this way, a single responsibility can reveal an imbalance that a list of completed chores would never show.

One exercise worth trying at home: each partner separately writes down the recurring responsibilities they believe they carry, covering household tasks, appointments, finances, family relationships, planning and emotional support. Comparing the two lists side by side, and talking through what's missing from each one, usually surfaces more than any conversation about who did the washing up.

When to call in the professionals

Some couples work through this on their own once they've named it out loud. Others find it keeps resurfacing in the same shape, no matter how many conversations they have about it. Needing support with that isn't a failure.

You might consider couples therapy if:

• you're having the same argument on repeat
• one or both of you is bringing up past hurts constantly
• you can't communicate without it escalating
• you're starting to wonder if it's worth it.

A good therapist isn't there to take sides or tell you to break up. They're like a referee who also teaches you better fighting techniques.

If any of this resonated and you think couples therapy might help, reaching out to a qualified couples therapist is a great place to start.
