Study finds women tend to favor sweet actions over sweet words in romantic partners

People often say that actions speak louder than words, but whether that holds true may depend on one’s sex. A new study published in Evolutionary Psychological Science suggests that women are more likely than men to prefer tangible expressions of affection—such as help with chores or small acts of care—over verbal declarations like “I love you” or “I’m here for you.” This preference appears to be tied to how women and men differently perceive warmth and trustworthiness in potential partners.

The research offers new insight into how small, everyday behaviors—rather than grand gestures or expensive gifts—can influence mate selection. While both men and women value warmth and trustworthiness in romantic partners, the study indicates that they differ in what kinds of signals they find most compelling during early courtship.

Much of the previous research on mate preferences has focused on large-scale traits like attractiveness, intelligence, or social status. While these qualities play a role in partner selection, they are relatively difficult to modify. In contrast, small expressions of affection—such as what someone says or does in daily life—can be adjusted more easily and may carry important social signals, especially during the early stages of a relationship.

The researchers were particularly interested in the perceived importance of “sweet words” versus “sweet actions.” Sweet words included phrases like “I miss you,” “I understand you,” or verbal encouragement. Sweet actions referred to small but tangible gestures, such as helping with errands or cooking a meal. These two types of behavior are common in everyday relationships and offer different ways of expressing care.

Drawing on evolutionary theory, the researchers predicted that women would be more likely than men to prefer sweet actions over sweet words. This prediction was grounded in theories of reproductive investment: Women tend to prioritize signs that a partner is dependable and willing to invest in the relationship, while men are more sensitive to signals of immediate emotional or sexual interest. Sweet actions may serve as better indicators of commitment, while sweet words might offer more immediate gratification.

The study was conducted across three experiments with 513 heterosexual Chinese adults recruited online. Each study was designed to test whether women and men differ in how they perceive and evaluate sweet actions versus sweet words, especially when choosing a romantic partner.

Study 1 asked participants to imagine scenarios in which their partner expressed affection either through words or actions. For example, a sweet word scenario involved a partner offering comforting words after a stressful day, while a sweet action scenario described a partner doing the laundry. Participants then rated how desirable these behaviors were.

The results showed a significant interaction between sex and affection type. Women rated sweet actions as more desirable than sweet words, whereas men showed the opposite pattern. Men favored verbal expressions of affection more than behavioral ones, although the effect was not as strong.

Study 2 introduced two hypothetical partner profiles: one who excelled at sweet words and one who was better at sweet actions. Participants chose which person they would prefer to start a romantic relationship with and rated how warm or trustworthy each one seemed.

Again, women showed a stronger preference for the partner who expressed affection through actions, and they rated this person as warmer and more trustworthy. Men showed a weaker preference overall and did not strongly differentiate between the two profiles. Importantly, the researchers found that the perception of warmth and trustworthiness explained the relationship between sex and mate preference—supporting the idea that women find actions to be stronger indicators of a partner’s emotional reliability.

Study 3 followed a similar design to Study 2 but used new profile descriptions and a more detailed measurement of perceived warmth and trustworthiness. The results replicated those of the earlier studies. Women again showed a stronger preference for sweet actions and rated those partners as warmer and more trustworthy. Men showed no significant preference and rated both types of partners similarly.

Across all three studies, the researchers tested whether participants’ usual style of expressing affection—either through words or actions—might explain their preferences. The results showed no sex differences in how people typically express affection themselves, suggesting that the preferences observed were not merely a reflection of habit or personal communication style.

The researchers focused on warmth and trustworthiness because these traits consistently appear at the top of people’s lists of ideal partner qualities. Prior studies have identified warmth, attractiveness, and status as three core dimensions in romantic attraction, with warmth and trustworthiness being the most important for long-term relationship satisfaction.

Sweet actions may be more meaningful in signaling warmth and trustworthiness because they require effort and are harder to fake. Words, while emotionally powerful, can be spoken without follow-through. From an evolutionary perspective, women may be especially sensitive to behaviors that signal a partner’s willingness to invest time and effort—key factors in successful parenting and long-term stability.

In contrast, men may be less reliant on these cues when forming judgments about a potential partner’s intentions or emotional depth. Verbal expressions of affection might be more immediately rewarding or easier to interpret as signs of romantic or sexual interest, especially in early stages of dating.

There are some limitations. First, the studies were based entirely on hypothetical scenarios and self-report measures. While these methods are useful for isolating variables and testing specific ideas, they do not necessarily reflect how people behave in real-world situations like speed dating or ongoing relationships.

Second, the sample consisted solely of Chinese participants. Cultural norms around gender roles and emotional expression vary widely, and it is not yet clear how these findings would generalize to other societies. Future studies could examine whether the same patterns appear across different cultural settings.

The study also did not account for variables such as attachment style, relationship history, or sociosexual orientation, all of which could influence how people interpret or prioritize expressions of affection. Future research might explore how these psychological factors interact with sex to shape romantic preferences.

Lastly, the study did not directly measure relationship outcomes. It remains to be seen whether preferences for sweet words or sweet actions are linked to greater satisfaction, trust, or longevity in actual relationships.
