New research indicates that women in heterosexual relationships report higher levels of relationship and sexual satisfaction when the "mental load"—the thinking and emotional work involved in managing a household and relationship—is shared with their male partners. Conversely, men tend to report greater satisfaction when their female partners shoulder more of this invisible labor.
The study, published in Personality and Social Psychology Bulletin, involved two parts. In the first, researchers surveyed 452 women living with male partners. The second part included 156 couples who answered questionnaires separately about their division of household labor and their relationship satisfaction.
Participants averaged 42 years old and had been together for 1 to 44 years. The research asked about specific responsibilities such as keeping track of children's schedules, deciding when household items need replacing, and noticing when a partner is upset. The findings revealed that women consistently shouldered a disproportionate amount of this invisible labor, regardless of their personal views on gender roles. This imbalance was observed even when physical chores were divided more equitably.
Verena Klein, a co-author of the study and a principal research fellow at the University of Southampton, stated that the findings illustrate how the same arrangement can benefit one partner while burdening the other. In the couples' data, both women and men acknowledged that women performed the majority of the mental load tasks, indicating a shared perception of the inequality.
"Men may benefit from having someone else take responsibility for organizing and managing everyday life," Klein told HuffPost. "This doesn’t necessarily mean they consciously prefer inequality, but it does suggest that traditional gender arrangements can remain comfortable for men, even when they come at a cost to women."
Laura Danger, an educator and author specializing in domestic labor, noted that women's worth is often tied to the state of their home, a phenomenon she calls the “nag paradox.” This societal expectation can contribute to women carrying the bulk of the mental load, as their morality is sometimes judged by their housekeeping. Danger suggests that men benefit from this work without being expected to share the load equally, while women are often left to manage the responsibility and advocate for fairness.
To foster more equitable partnerships, Danger recommends focusing on equal autonomy rather than a strict 50/50 split. She advises couples to treat their household like a collaborative project, discussing fairness openly, leveraging individual strengths, sharing less desirable tasks, and regularly revisiting their arrangements.
Rotem Kahalon, the study's lead author, also offered advice: do not wait for a partner to be asked to take on a task. She emphasized the distinction between a single chore, like taking a child to the dentist, and the ongoing responsibility of managing appointments and follow-ups. Kahalon added that in relationships, what matters most is that both partners feel equally responsible for and cared for in the life they are building together.
