There’s now a validated instrument for mankeeping — the unpaid work of managing a male partner’s friendships — and it tracks with worse relationship satisfaction and more burnout for the women who do it. That’s what changed.

Measuring Mankeeping: Development and Validation of a Scale Assessing How Women Experience the Impact of Men’s Declining Social Networks, published in Sex Roles and covered by PsyPost on September 18, 2026, took a 62-item pool of candidate statements to 402 U.S. women in heterosexual relationships of six months or longer and factor-analyzed it down to a 46-item scale — six factors, good reliability, the whole psychometric apparatus. What it measures is oddly specific and instantly recognizable: the work of managing a male partner’s friendships. Scheduling the reunion he won’t schedule. Texting his college roommate to set up the trip. Asking, again, if he’s talked to anyone besides you this week. The researchers called this “mankeeping.” Simone de Beauvoir didn’t have that word in 1949. She had a better one — immanence — and she used it to describe exactly this structure, seventy-seven years before anyone thought to build a survey instrument around it.

The Quick Version

A 2026 Sex Roles study built and validated a scale measuring “mankeeping” — the unpaid work women do sustaining their male partners’ friendships and social lives — and found it correlates with burnout, relationship strain, and lower satisfaction. Women with more traditional views of gender roles reported doing more of it. Simone de Beauvoir named this exact division of labor in 1949: woman assigned to the maintenance work of existence, man freed to go do things in the world, her labor treated as the natural backdrop to his.

What the Study Actually Found

The researchers didn’t start from a theory about existentialism. They started from a real, documented problem: American men’s friendships have been shrinking for decades. The Survey Center on American Life’s 2021 report found the share of men with six or more close friends fell from 55% in 1990 to 27%, while the share with no close friends at all rose from 3% to 15% — a fivefold jump, in one generation, among American men. Somebody has to notice when a friendship lapses. Somebody has to suggest the group chat, remember the birthday, nudge the reunion into existing. The mankeeping study set out to measure who that somebody usually is, and what it costs her.

The 46 items split into six factors, and they’re worth naming because the specificity is the point: the actual behaviors of managing a partner’s social calendar and connections, the emotional toll those behaviors take, a felt sense that the labor is unequal and goes unacknowledged, how the woman appraises her partner’s social network on his behalf, her own desire for him to have more friends, and the degree to which he leans on her emotionally in place of a wider circle. That’s not one thing being measured. It’s a whole ecosystem of managing someone else’s inner life from the outside.

The correlations are where it gets uncomfortable. Higher scores on the scale tracked with lower relationship satisfaction and higher relationship burden and burnout — and per PsyPost’s coverage, five of the six factors also correlated positively with the women’s own depression, anxiety, and stress. Lead researcher Vincent Mancini put it plainly: “Women who engage in these behaviors more tended to show poorer relationship satisfaction, which may signal the importance of social connections.” And the group most likely to be doing the heaviest mankeeping wasn’t defined by income, age, or relationship length. It was defined by ideology — women who held more traditional views about gender roles reported doing substantially more of it. The belief that this is simply what a good partner does turned out to predict the workload.

What Is Mankeeping, Exactly?

1. Scheduling and initiating his social life. Setting up the guys’ trip he keeps meaning to plan, texting his friends on his behalf, keeping his social calendar populated because it won’t populate itself.
2. Absorbing the emotional toll of that work. Fatigue, resentment, or guilt tied specifically to managing someone else’s connections rather than her own.
3. Registering the labor as unequal and unseen. A felt sense — measured directly by the scale — that this support runs one direction and isn’t recognized as work at all.
4. Monitoring the state of his network. Tracking, often without being asked, whether he has anyone besides her to talk to.
5. Wanting more for him than he’s building for himself. A desire for his social world to be bigger than it currently is, independent of her own needs.
6. Functioning as the primary emotional outlet. Being the main — sometimes the only — place his emotional needs land, in place of a friend group.

What Beauvoir Meant by Immanence and Transcendence

Here’s the concept stripped down to its working parts.

In The Second Sex (1949), Simone de Beauvoir argues that human existence has two dimensions: transcendence — reaching beyond the given moment through projects, work, and creation — and immanence — the repetitive maintenance that keeps life going but produces nothing new. Every person needs both. But under patriarchy, she argued, women have been assigned immanence as their whole existence, freeing men to claim transcendence as theirs, and the maintenance work gets treated as nature rather than labor.

De Beauvoir wasn’t writing about friendship apps or group chats. She was writing about cooking, cleaning, child-rearing — the work that has to be redone every day and leaves no monument behind. But the structure she named doesn’t care what the maintenance task is. It cares who does it and who gets credit for having a life because of it. The Stanford Encyclopedia’s entry on Beauvoir puts the mechanism precisely: masculinist ideology positions women as the Other, anchored to immanence through both social practice and lived experience, while men treat transcendence — the going out into the world, the doing of projects, the having of a social life that isn’t managed by someone else — as simply theirs by default.

A man’s friendships are, on this framework, a transcendence project. Building them, sustaining them, showing up for them: that’s supposed to be his active engagement with the world. What the mankeeping study found is that a lot of that project has quietly been outsourced. He gets the transcendence — the friendships, when they exist, the sense of a full life. She does the immanence that makes it possible, and per the scale’s own third factor, she knows it isn’t being counted as anything.

Why the Study and the Philosophy Rhyme

The connection isn’t that Beauvoir predicted factor analysis. It’s narrower than that, and I think more useful: both are describing the same asymmetry, one philosophically and one statistically. Beauvoir’s claim was structural — that a society organizes maintenance labor onto women and calls it love, instinct, or nature, so that it never has to be counted, negotiated, or paid. The 2026 study’s third factor — the felt sense that support is unequal and unacknowledged — is that exact claim showing up as a survey response instead of a philosophical argument. Women aren’t just doing the work. They’re registering, item by item, that it isn’t being seen as work.

This is close kin to what Hegel’s recognition theory names from a different angle: a lot of psychological injury isn’t about the labor itself but about doing labor that structurally cannot be acknowledged, because acknowledging it would mean admitting it was labor at all. Call it instinct, call it “just being a good girlfriend,” and the work disappears from view precisely by being done well.

It also lines up with something this site covered in de Beauvoir’s own Ethics of Ambiguity: her argument that genuine freedom can’t be a solo project, because it’s constituted in relation to others. Mankeeping is what happens when that relational requirement gets loaded onto one partner without the other’s participation. His social transcendence depends on her relational work. Hers doesn’t get to depend on anything, because she’s too busy supplying his.

What This Doesn’t Mean

It doesn’t mean every man with a woman managing his birthday texts is a Beauvoirian villain, or that every couple where this happens is in crisis. The study measured a correlation across a sample of partnered women, not a verdict on any one relationship. Some mankeeping is small, occasional, and freely given without cost — Aristotle’s three types of friendship already draws the line between labor that serves mutual flourishing and labor that’s just extraction with better manners.

It also doesn’t mean traditional gender-role beliefs are the only cause. The study found a correlation, and a real one, but the friendship recession men are living through has structural causes too — the loss of institutions that used to build friendship as a byproduct (sports leagues, unions, church groups, the third places this site has written about before). A woman managing her partner’s social life isn’t only propping up his choices. Sometimes she’s propping up the absence of scaffolding that used to do this work for men automatically, before it collapsed.

And it doesn’t mean the fix is a chore chart for friendship. Simmel’s warning about social networks applies here too — friendships built entirely on someone else’s initiative aren’t really his network. They’re an extension of hers, wearing his name.

What Actually Follows From This

Three things, roughly in order of how uncomfortable they are to say out loud.

1. Name the labor before deciding whether to do it. Beauvoir’s whole point about immanence is that it works by being invisible — mistaken for nature instead of recognized as a choice being made. Noticing “I am the one texting his friends” is not an accusation. It’s the first fact you need before you can decide anything else.
2. Ask whether the friendship exists because of him or because of you. A social life that only runs on someone else’s scheduling isn’t transcendence in Beauvoir’s sense — reaching outward through one’s own project. It’s borrowed motion. The study’s own factors suggest women can already feel this difference; they scored it separately from the labor itself.
3. Don’t confuse doing this well with it not being work. The third factor in the scale exists because researchers found that the ache of unacknowledged labor is measurable and distinct from the labor. If it’s landing as invisible, that’s not because it’s small. It’s because it’s working exactly the way immanence has always worked.

The Word Beauvoir Used That the Study Doesn’t Need

The Mankeeping Scale never uses the word “immanence.” It didn’t need to. It built six factors and a validated instrument around a structure de Beauvoir spent six hundred pages describing without a single regression table, and arrived, from a completely different direction, at the same discovery: unpaid maintenance work doesn’t disappear because it’s called love. It gets absorbed by whoever agrees to stop noticing it’s work.

What the study adds that philosophy alone couldn’t is a number. Women scoring high on mankeeping report worse relationship satisfaction and more burnout — not as a philosophical prediction now, but as a measured finding in 402 women’s actual lives. De Beauvoir would recognize the shape instantly. She’d probably also point out that a scale to measure the labor is progress a book alone could never manage — and still just the first step toward it being shared instead of counted.
