The advice to “have no expectations of others” tends to sound like a recipe for indifference, as if lowering the bar means caring less. Two studies looking at real couples suggest something more precise is going on: expectations don’t just color how a person judges what someone else does, they actively determine whether the exact same behavior registers as meaningful at all.
The clearest evidence comes from a 2020 study by Gesine Zoppolat, Mariko Visserman, and Francesca Righetti, published in the Journal of Social and Personal Relationships. The researchers ran a daily-experience diary study with 253 individuals in romantic relationships, tracking moments when participants perceived their partner making a sacrifice for them, along with their expectations about how normal or necessary sacrifice was in a relationship, and their resulting feelings of gratitude, respect, and satisfaction. When people perceived a partner’s sacrifice, it boosted their gratitude and, in turn, their relationship satisfaction, but only when their own expectations for sacrifice were relatively low to begin with. For people who held strong expectations that sacrifice was simply normal and necessary in a relationship, the identical sacrificial act produced no measurable boost in appreciation or satisfaction at all. The exact same behavior from a partner either registered as a meaningful gift or barely registered at all, depending entirely on what was expected going in.
A second study helps show that the reverse is true as well, unmet expectations of a partner carry real, lasting costs to relationship quality. In a 2012 study by Lauren Dixon, Kristina Gordon, Nicole Frousakis, and Jeremiah Schumm, published in Family Relations, the researchers surveyed 242 participants attending marital enrichment seminars across 12 U.S. cities, assessing them before the seminar, immediately afterward, and again two months later. Larger gaps between what people expected of their spouse’s effort and what they actually perceived predicted lower satisfaction with that effort. Critically, it was dissatisfaction specifically with the spouse’s effort, not with one’s own, that significantly predicted lower overall marital quality at the two-month follow-up, even after accounting for how satisfied couples were with their marriage at the study’s start. It wasn’t a person’s own performance weighing on the relationship, it was the gap between what they expected from their partner and what they got.
Together, these two studies suggest that expectations of others function less like a simple prediction and more like a lens that determines what even counts as a positive or negative event in a relationship. Zoppolat and colleagues’ research shows that lower expectations don’t dull appreciation, they’re what make appreciation possible in the first place, since an identical sacrifice registered as meaningful only when it wasn’t already assumed. Dixon and colleagues’ research shows the flip side: when expectations of a partner’s effort run ahead of what’s actually delivered, that specific gap, not general relationship unhappiness, predicts real decline in marital quality months later. Neither study suggests indifference toward a partner. Both point toward the same underlying mechanism, that the size of the gap between expectation and reality, more than the behavior itself, is what a relationship actually runs on.
It’s worth being honest about what these two studies don’t establish. Zoppolat and colleagues’ research is correlational, tracking naturally occurring expectations and sacrifices as they happened rather than experimentally manipulating expectations directly, so while the pattern is strong and consistent across the diary data, it can’t fully rule out that people with generally warmer relationships also happen to hold lower baseline expectations for other reasons. Dixon and colleagues’ research was conducted specifically with couples who had voluntarily attended a marital enrichment seminar, a group already motivated to work on their relationship, so the pattern may look somewhat different in couples who aren’t actively seeking that kind of support.
Within those honest limits, the research offers a genuinely useful correction to what “having no expectations” actually means. It isn’t about caring less or expecting nothing from the people who matter. It’s that holding expectations too high can quietly erase the ability to notice and appreciate what a partner actually does, while the gap between what’s expected and what’s delivered, not the behavior in isolation, is what seems to genuinely shape how a relationship holds up over time.
