Social context influences dating preferences just as much as biological sex

A recent study published in Evolution and Human Behavior suggests that a person’s socioeconomic background plays a massive role in shaping what they look for in a romantic partner. The findings provide evidence that the surrounding environment and access to resources often influence dating preferences just as much as biological sex. Ultimately, this research challenges rigid stereotypes about male and female behavior, showing that human mating strategies adapt fluidly to social conditions.

Historically, evolutionary psychology has focused heavily on the biological differences between men and women when it comes to choosing a partner. The standard framework suggests that men tend to prioritize physical attractiveness to maximize reproductive success, while women tend to prioritize resources to ensure stability for offspring. However, human dating behavior is highly complex and responsive to environmental pressures.

The authors of the new study wanted to better understand how resource availability and social standing interact with these biological predispositions. They wanted to see if people from different socioeconomic backgrounds adjusted their romantic preferences and their self-esteem to fit their specific life circumstances. By examining these environmental factors, the researchers aimed to build a more nuanced understanding of how people actually navigate the modern dating market.

When searching for a romantic partner, people often observe their rivals and infer their own market value through comparison. The researchers wanted to test how exposure to highly attractive or successful competitors might shift a person’s confidence. They suspected that realizing one’s own standing in the local dating pool directly shifts what a person demands in a future partner.

“The topic of romantic partner choice has always interested me, and I have been researching it since my undergraduate years. During my PhD, I continued to investigate partner preferences, but as theories like Strategic Pluralism Theory suggest, context significantly influences how people choose their partners,” explained study author Anthonieta Looman Mafra, a postdoctoral fellow at the University of São Paulo.

“I based my study on the work of Castro et al. (2014), who investigated how exposure to different rivals influenced partner choice, but with an additional factor: living in Brazil, one notices that behaviors change significantly according to different groups. Most research is conducted with convenience samples (i.e., university students), which does not represent the majority of the Brazilian population. Brazil is a socioeconomically unequal country, so different preferences for romantic partners were not only possible but understandable. Therefore, I dedicated myself to collecting data from people with lower socioeconomic status to better understand the Brazilian reality.”

To investigate these dynamics, the researchers recruited 1,166 young adults from Northeast Brazil. The sample consisted of 511 individuals from higher socioeconomic backgrounds, mostly university students, and 655 individuals from lower socioeconomic backgrounds, mostly public middle and high school students. All participants were within a similar age range.

The scientists divided the participants into control and experimental groups to measure their self-esteem, self-perception as a romantic partner, and partner preferences. The experimental group viewed four fabricated profiles of same-sex rivals. These profiles featured photographs and descriptions that varied in physical attractiveness, social skills, and social status.

After viewing these potential dating competitors, participants answered a series of questions. They rated their own desirability on a ten-point scale across categories like physical appearance, sociability, and financial condition. They also detailed exactly what traits they desired in both short-term and long-term romantic partners.

The data revealed differences based on socioeconomic standing. Participants from lower socioeconomic backgrounds rated themselves as more physically attractive than those from wealthier backgrounds. In contrast, higher socioeconomic participants considered themselves to have superior social skills.

This pattern suggests that people evaluate themselves based on the resources most accessible to them in their specific environment. For people with fewer financial resources, physical appearance might act as a primary form of social currency. Meanwhile, wealthier individuals might lean on their communication abilities and networking skills, which are often fostered by advanced educational opportunities.

When it came to long-term relationships, socioeconomic background continued to dictate preferences. People from lower socioeconomic groups placed greater importance on physical attractiveness in a long-term partner. On the other hand, individuals from wealthier backgrounds prioritized social skills for long-term commitments.

The scientists suggest that in resource-unstable environments, physical attractiveness might serve as a key indicator of health and genetic quality. In more stable, wealthier environments, social skills become highly prioritized because they help maintain and advance a person’s existing social standing. In this way, people tend to seek out partners who mirror their own perceived strengths.

Despite these strong environmental influences, biological sex still played a role in specific situations. For short-term encounters, men preferred physical attractiveness more than women did. Meanwhile, women reported stronger preferences for general attractiveness, social skills, and social status in short-term partners compared to men.

Interestingly, both men and women from lower socioeconomic backgrounds expressed stronger preferences for social skills and social status in short-term partners than wealthier participants did.

“Initially, I did not expect men of lower socioeconomic status to prefer partners with higher social status; rather, I expected women of lower socioeconomic status to show a stronger preference for men with higher physical attractiveness,” Mafra told PsyPost.

The researchers also noticed a specific reaction when participants faced highly attractive rivals. When lower socioeconomic women were exposed to profiles of highly attractive female competitors, they significantly increased their preference for social status in a long-term partner.

The researchers propose that facing intense physical competition in the dating market may prompt these women to seek out partners with resources to ensure future stability. The static rival profiles did not broadly lower participants’ self-esteem, but rather fine-tuned what certain groups looked for in a relationship. Throughout all groups, having a high baseline of self-esteem buffered participants against feeling threatened by the fabricated rivals.

“The average person should recognize that men and women are far more alike than different,” Mafra said. “Despite the growing wave of conservatism that claims men and women are biologically programmed to behave in specific, rigid ways, our findings show that other factors often play a much larger role in shaping behavior than biological sex alone. Moving away from these reductive views—which limit women to passivity and child-rearing and men to being mere providers—allows for a much more accurate and nuanced understanding of how we actually choose our partners.”

While the study provides new insights into dating psychology, the average reader should be cautious about generalizing the results too broadly. One limitation is the use of static photographs and written descriptions to simulate dating rivals. Reading a profile on paper does not fully recreate the intense competitive pressure of a real-world social interaction. This lack of real-time pressure might explain why the rival profiles did not significantly alter most participants’ overall self-perception.

“This study was conducted using exposure to rivals through a booklet with photos and descriptions, which is quite different from exposure in a real-world context where you are actually in an environment with rivals and potential romantic partners,” Mafra noted. “Conducting that type of research would be much more complex and was not possible at the time. Therefore, we cannot assume that exposure to rivals has no influence on our behavior, nor that the influence rivals exert on partner preference is controlled solely by an individual’s self-esteem; a broad set of factors likely plays a role.”

Additionally, comparing university students to public school students captures a very specific cultural and educational divide in Brazil. These two groups may have different immediate life goals, such as finding a job right away versus pursuing higher education. These different life trajectories could easily influence their short-term and long-term dating strategies.

While there are many avenues left to explore regarding socioeconomic status and mating preferences, Mafra is temporarily shifting her attention to another pressing psychological issue.

“For now, I am focusing on LGBTQIA+ mental health and whether there is an improvement in mental health after participating in potential intervention strategies for these purposes,” she explained. “I hope to return to this line of research in the near future.”
