Why High-Income Moms Still Do All The Planning: The Mental Load Money Can’t Fix

Mom may earn six figures, but chances are she’s still stuck carrying the cognitive load of raising the family.

She makes six figures. She can afford housekeepers and meal delivery. She works 50 hours a week. And yet, she’s still the one who knows when the pediatrician appointment is, which kid needs new shoes, and that the dog’s vaccinations are due next month.

It may surprise many to read, but mothers earning $100,000 or more annually show no significant difference in cognitive load compared to mothers earning far less.

A study of more than 2,000 American parents reveals that the most stubborn form of household inequality isn’t the kind you can see. While working mothers have successfully reduced their hours spent scrubbing, cooking, and doing laundry, they remain trapped by an invisible burden that researchers call cognitive labor. Also known as the mental load, cognitive labor in this context refers to the constant mental work of remembering, planning, coordinating, and anticipating family needs.

Money helps with the physical work, but it doesn’t touch the mental load, according to research published in the journal Socius. High-income women spend dramatically fewer hours on physical housework and childcare, often approaching levels reported by fathers. But when it comes to mental work—the planning, tracking, and decision making—being wealthy or being employed makes no measurable difference.

Time and Money Fall Short for the Mental Load

The finding exposes a hidden barrier to gender equality that helps explain why progress has stalled. Women have entered the workforce in massive numbers. Their earnings have increased. Couples increasingly share physical household tasks. Yet mothers still shoulder responsibility for managing the rhythms and details of daily family life, and that imbalance persists across every income bracket.

The authors introduce a concept they call gendered cognitive stickiness. Once assigned on the basis of gendered expectations, cognitive tasks stick to mothers and resist negotiation, regardless of employment or resources. This happens because the work is largely invisible, happening inside your head rather than in visible action, and making it nearly impossible to delegate or even recognize.

Cognitive labor is distinct from the physical tasks most people associate with housework. Washing dishes takes 15 minutes. Planning meals for the week is different. It means checking what’s in the pantry, making a shopping list, and remembering dietary restrictions. This work is ongoing and diffuse. It happens in the car, at the office, while trying to fall asleep.

The researchers identified cognitive labor as anticipating needs before they arise, making decisions about everything from medical care to social commitments, and monitoring whether tasks actually get done. Unlike physical chores, cognitive work isn’t bound by time or space. A mother can be mentally coordinating soccer practice while sitting in a work meeting.

To measure this invisible labor, the research team surveyed 2,133 heterosexual, partnered parents across the United States. Respondents indicated who in their household typically handles 21 cognitive tasks spanning seven areas: scheduling, childcare logistics, social relationships, cleaning management, food planning, finances, and home maintenance.

A 68 Percent Gap

Mothers reported primary responsibility for an average of 13.72 tasks compared to 8.18 for fathers, a gap of about 68 percent. Breaking down the categories revealed even starker patterns. Women held primary responsibility for 2.44 scheduling tasks versus 0.83 for men. For cleaning-related planning, the split was 2.40 to 0.90. Childcare cognitive work: 2.14 for mothers, 0.77 for fathers.

Fathers reported more responsibility in only two areas: finances (1.71 tasks for fathers versus 1.43 for mothers) and home maintenance (1.99 versus 1.12). These represent the only domains where fathers take the lead, though the gaps are smaller than those in mother-dominated categories.

Traditional economic theories suggest that when women earn more, they gain bargaining power at home. More income should mean fewer household obligations. The study confirmed this logic works for physical tasks.

High-earning mothers (those making $100,000 or more) spent 30 percent less time on physical childcare and 17 percent less on other housework compared to lower-earning mothers. Employed mothers, regardless of income, spent 17 percent less time caregiving and 22 percent less time on chores than non-employed mothers.

But cognitive labor told a different story. Employment status made no difference. High income made no difference. Mothers at every earning level and employment status reported managing similar numbers of mental tasks.

The authors argue that this is where time and money hit their limits: employed and high-earning mothers report the same cognitive burdens as those with less time or income.

Even mothers who outearned their partners, upending traditional breadwinner roles, carried the bulk of cognitive labor. Being the family’s primary earner did not shift who remembers permission slip deadlines or tracks when kids outgrow their clothes.

Why Fathers’ Experience Differs

Compare that to fathers. For men, employment reduced cognitive labor by roughly 29 percent. High income also changed what mental work fathers took on, though in selective ways. Wealthy fathers engaged more in cognitive tasks around childcare, scheduling, and social planning but focused largely on episodic, less frequent activities like researching elite summer camps rather than daily tasks like meal planning or appointment tracking.

The pattern suggests that fathers with resources engage in cognitive labor that aligns with cultural ideals of involved fatherhood while avoiding the constant, invisible monitoring that mothers handle. Their money buys them into episodic tasks and out of daily, mundane ones. For mothers, money offers no such choice.

To explain why cognitive labor resists economic bargaining, the authors introduced gendered cognitive stickiness. Physical household tasks can be delegated, outsourced, or visibly performed. Cognitive labor is different.

Most of it happens inside one’s head. A mother might delegate driving a child to a doctor’s appointment, but she often retains responsibility for scheduling it, monitoring vaccination timelines, completing paperwork, and coordinating with work and school schedules. Prompting or reminding a partner to handle these details doesn’t relieve the mental burden; it reinforces it.

When women anticipate that tasks will go undone or be done poorly without their oversight, they continue monitoring. The invisible nature of this work makes it nearly impossible to negotiate or redistribute.

Cognitive labor typically becomes visible only when something goes wrong. For example, a forgotten appointment, or a missed deadline. That’s when mothers get blamed.

The Scale Beyond Just Mental Work

The imbalance extends beyond cognitive tasks. Mothers in the study reported doing 47.86 hours per week of physical care work compared to 25.86 hours for fathers. For other household work like cooking and cleaning, mothers averaged 25.02 hours weekly versus 14.61 for fathers.

When researchers compared mothers and fathers at similar income and employment levels, the gender gaps in physical labor narrowed considerably. High-earning mothers and high-earning fathers spent roughly comparable time on housework. But the cognitive labor gap barely budged.

Across every subgroup analyzed—employed mothers with young children, breadwinning mothers, highly educated mothers—women carried dramatically more mental responsibility than comparable fathers. Even in the most advantaged circumstances, where both partners earned substantial incomes, mothers still managed most cognitive tasks.

The study controlled for age, education, race, number of children, and age of youngest child. The pattern held.

The Stalled Revolution

The persistence of cognitive labor inequality helps explain what researchers call the “stalled gender revolution.” Women’s mass entry into the workforce was supposed to transform home life. Early gains were significant. Men increased time spent on childcare and housework. Couples became more egalitarian in how they divided physical tasks, especially in affluent, educated households.

But progress has slowed. The cognitive labor gap represents a form of inequality that may be more entrenched than often assumed, persisting even among privileged women. Cognitive labor’s invisibility exposes a hidden barrier to progress, a key mechanism that helps explain why the gender revolution stalled.

If mothers continue to hold primary responsibility for managing family life regardless of their financial contributions, then achieving equality at home requires more than women working and earning more. Physical tasks can be outsourced with money. Mental responsibility cannot be as easily transferred because it’s diffuse, ongoing, and usually invisible.

The researchers noted that fathers’ selective engagement with cognitive labor matters too. Men with high incomes took on more cognitive work in specific domains, particularly around children’s education and activities. But they focused on less frequent tasks that carry cultural status while largely avoiding daily mental work like meal planning or remembering to buy toilet paper before the household runs out.

This selective participation reinforces rather than challenges traditional gender patterns. Fathers engage in the cognitive labor that fits their identity as providers and involved parents. Mothers remain responsible for everything else.
