The Mental Load Has a Number, and It Is 71 Percent
A survey of 3,000 US parents put a number on it. Here is what the 71 percent means, and what to do with it.
The mental load study behind the 71 percent figure describes a familiar mismatch: a mother feels responsible for keeping the household moving, while her partner sincerely believes the work is shared equally. The useful next step is to make remembering, planning, and checking visible alongside the chores people can see.
What the mental load study’s 71 percent means
The British Psychological Society Research Digest summary describes research by Weeks and Ruppanner, published in the Journal of Marriage and Family as “A typology of US parents’ mental loads: Core and episodic cognitive labor.” The researchers surveyed 3,000 US-based parents of children aged 18 and younger.
The work covered seven categories: cleaning, scheduling, childcare, maintenance and repairs, finances, social relationships, and cooking. These categories include thinking that precedes visible action. Cooking involves remembering what is available and planning what people can eat, as well as preparing the meal.
Mothers reported handling 71% of tasks requiring mental effort; fathers reported 45%. For daily jobs such as cleaning and childcare, the figures were 79% for mothers and 37% for fathers. For episodic tasks, such as repairing a broken appliance, fathers took on 65%, while mothers still handled 53%.
The difference between daily and episodic work helps explain why apparently reasonable accounts of contribution can feel incompatible. A noticeable repair has a beginning and an end. Remembering what needs cleaning or preparing for childcare returns as soon as the immediate job is finished.
Why the mental load study’s figures overlap
Each parent answered about their own involvement, and responsibilities can be shared. These figures describe the share of tasks people reported handling; they are not mutually exclusive portions of a single household’s workload. Adding the mothers’ and fathers’ figures therefore does not produce a division of the same pie.
For example, parents can both report thinking about childcare arrangements. That does not establish that they spend equal effort on it, nor does it mean either response must be false. The measures capture reported responsibility, with overlap and differences in perception.
The digest also reports that parents overestimated their contributions, with fathers much more likely to do so and often seeing the work as equally shared. That finding helps explain the mismatch, but it cannot tell you exactly what is happening in your own household.
The authors acknowledge a central limitation: cognitive labor is invisible and difficult to measure over time. Treat the study as evidence that the problem deserves attention, rather than a scorecard that assigns your family a result.
Why daily remembering feels so heavy
Consider a school form. The visible action is returning it. Before that, somebody notices the message, works out which child it concerns, reads the requirements, finds the necessary information, and remembers the deadline. Afterwards, somebody may check that it arrived.
If a partner says “send it to me and I’ll do it,” the physical action may move while the monitoring stays put. The original parent still has to notice the request, delegate it, and decide whether to follow up. Help has occurred, but ownership may not have changed.
Daily work also interrupts other thinking. You can finish making lunch while still remembering that tomorrow needs different supplies. An episodic repair can be demanding, yet it usually has a clearer stopping point. The pressure comes partly from repetition and partly from staying responsible between visible tasks.
This does not make repairs unimportant or turn every household difference into unfairness. It means that comparing completed chores alone leaves out part of what makes the work tiring.
Make a shared list that replaces a question
Use a place both adults already know how to open: a paper list, a note, or a document. Start with current obligations rather than trying to inventory your entire family life. Each entry needs a recognizable task, an owner, the relevant information, and what completion looks like.
For a school trip, that might mean “return the permission form,” the adult responsible, where the form is, and confirmation that it was submitted. Add the actual deadline from the request. Avoid a vague entry such as “school stuff,” which leaves somebody else to interpret the work.
Agree where new requests go. If information arrives with either parent, that person needs a predictable way to make it available to the owner. Otherwise the list becomes another place the already overloaded parent has to maintain.
A useful test is whether the owner can answer the next practical question from the record. If they must ask where the form is or which version matters, the handoff still has missing context.
Transfer responsibility for remembering
Choose an area that can belong to an adult from beginning to end. For example, responsibility for school forms includes checking the relevant school communications, finding the current request, handling submission, and following up when necessary. Agree on any decisions that still require discussion.
The owner chooses how to remember the work. A calendar entry, a personal reminder, or a routine can all help, but setting up that system belongs with the task. If the other parent must keep prompting, the responsibility has not fully moved.
Define a handoff clearly enough to prevent avoidable uncertainty, then leave room for different methods. Completion may matter more than matching the original parent’s preferred sequence. Where there are essential requirements, put those in the task instead of relying on unspoken expectations.
If something changes, the owner brings the problem back with the relevant information. That is different from silently returning responsibility through repeated requests for instructions.
Have the conversation through the work
Choose a calm moment and bring the actual list. Describe what is happening in concrete terms: “I am keeping track of whether these forms have been returned, even when you submit them.” That is a description of work somebody can take over.
Ask which responsibilities each adult can own, considering work schedules, access to information, and other demands. Equal care does not require identical tasks. The useful agreement is explicit enough that neither person has to guess who is watching an approaching deadline.
Agree how to flag a task that cannot be completed before its deadline. The owner should say what is blocked and what help they need, rather than waiting for the other adult to notice. Make any temporary cover explicit so it does not quietly become the usual arrangement.
Return to the arrangement after ordinary life has tested it. If a task keeps bouncing back, find the missing access, unclear boundary, or unrealistic expectation. Review the system without requiring the overloaded parent to document every forgotten detail as evidence.
Let a saved document carry some of the remembering
With dEssence, a parent manually forwards or saves a message or document through the Chrome extension, Telegram bot, or web app. On Pro, documents can become dates and tasks; you can save the form and ask dEssence to remind you before Friday, then ask in your own words when it is due. It does not connect to email, calendars, ClassDojo, Seesaw, ParentSquare, PowerSchool, or Remind, and it does not read your inbox. You choose what to supply and set the reminder; it is not a shared household account.
Before relying on a saved request, check that it includes the attachment and identifies the child it concerns. Compare the reminder with the deadline in the original. If the school sends a correction, save that update and check whether the reminder needs changing too.
A tool can hold the information, but adults still need to agree who owns the action. The most useful change is not a more elaborate list. It is being able to stop carrying a task because somebody else has its context, its deadline, and responsibility for seeing it through.
