Recent research published in evolution and human behavior suggests that a person’s socio-economic background plays a large role in shaping what they seek in a romantic partner. This finding provides evidence that the surrounding environment and access to resources often influence dating preferences as much as biological sex. Ultimately, this study questions rigid stereotypes about male and female behavior and shows that human mating strategies fluidly adapt to social conditions.
Historically, evolutionary psychology has focused on the biological differences between men and women when choosing a partner. Standard frameworks suggest that men tend to prioritize physical attractiveness to maximize reproductive success, whereas women tend to prioritize resources to ensure offspring stability. However, human dating behavior is highly complex and sensitive to environmental pressures.
The authors of the new study wanted to better understand how resource availability and social status interact with these biological predispositions. They wanted to know whether people from different socio-economic backgrounds adjusted their romantic preferences and self-esteem to fit their life situations. By examining these environmental factors, the researchers aimed to build a more nuanced understanding of how people actually navigate the modern dating market.
When looking for a partner, people often estimate their market value by observing and comparing their rivals. The researchers wanted to test how a person’s self-confidence changes when exposed to highly attractive or successful competitors. They suspected that being aware of one’s position in a local dating group would directly change what that person looked for in a future partner.
“The topic of romantic partner selection has always interested me and I have been researching it since my undergraduate days. During my doctoral studies, I continued to study partner preferences, and as theories such as strategic pluralism suggest, context strongly influences how people choose partners,” explained study author Antonieta Luman Mafra, a postdoctoral researcher at the University of São Paulo.
“I based my study on the work of Castro et al. (2014), who investigated how contact with different rivals affects partner choice. In this study, we investigated how contact with different rivals affects partner choice, but there are additional factors. Living in Brazil, you notice that different groups behave significantly differently. Most studies It was carried out using a representative sample (i.e. university students) and is not representative of the majority of the Brazilian population. Brazil is a socio-economically unequal country, so differences in preferences for romantic partners were not only possible, but understandable. I therefore dedicated myself to collecting data from people of lower socio-economic status to better understand the Brazilian reality. ”
To examine these dynamics, researchers recruited 1,166 young people from northeastern Brazil. The sample consisted of 511 people from high socio-economic backgrounds (mainly university students) and 655 people from low socio-economic backgrounds (mainly public middle school and high school students). All participants were of a similar age group.
The scientists divided participants into control and experimental groups and measured their self-esteem, self-perception as a romantic partner, and partner preference. The experimental group viewed four fabricated profiles of same-sex rivals. These profiles included a variety of photos and descriptions, including physical attractiveness, social skills, and social status.
After identifying these potential dating competitors, participants answered a series of questions. They rated their own likeability on a 10-point scale across categories such as appearance, sociability, and financial status. They also detailed what characteristics they desired in short-term and long-term romantic partners.
The data revealed differences based on socio-economic status. Participants from lower socio-economic backgrounds rated themselves as more physically attractive than participants from more affluent backgrounds. In contrast, higher socio-economic participants considered themselves to have better social skills.
This pattern suggests that people evaluate themselves based on the resources that are most accessible in a particular environment. For those with less financial means, appearance can serve as a major form of social currency. Wealthy individuals, on the other hand, may rely on the communication and networking skills developed through advanced educational opportunities.
Socioeconomic background continued to determine preferences when it came to long-term relationships. People from lower socio-economic groups placed more importance on physical attractiveness in long-term partners. On the other hand, people from wealthier backgrounds prioritized social skills for long-term commitment.
Scientists have suggested that physical attractiveness may serve as an important indicator of health and genetic disposition in environments where resources are unstable. In more stable and affluent environments, social skills are highly prioritized because they help maintain and improve a person’s existing social status. As such, people tend to seek out partners who reflect their own perceived strengths.
Despite this strong environmental influence, biological sex still plays a role in certain situations. In short-term encounters, men prefer physical attraction over women. On the other hand, 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 socio-economic backgrounds expressed a strong preference for the social skills and social status of short-term partners over wealthier participants.
“Initially, I did not expect that men of lower socio-economic status would prefer partners of higher social status. Rather, I expected that women of lower socio-economic status would have a stronger preference for men with higher physical attractiveness,” Makhura told Cypost.
The researchers also noticed specific reactions when participants faced highly attractive rivals. When women of low socioeconomic status were exposed to the profile of a highly attractive female competitor, their preference for social status in a long-term partner increased significantly.
The researchers propose that facing intense physical competition in the dating market may lead these women to seek out partners with the resources to ensure future stability. Static rival profiles did not broadly reduce participants’ self-esteem, but rather fine-tuned what specific groups wanted in a relationship. In all groups, having a high baseline of self-esteem made participants feel less threatened by fabricated rivals.
“The average person should realize that men and women are far more similar than different,” Makhura said. “Despite a growing wave of conservatism that claims that men and women are biologically programmed to behave in certain rigid ways, our findings demonstrate that other factors play a much larger role in shaping behavior than biological sex alone. Moving away from these reductive views that limit women to passivity and nurturing, and men to mere providers, allows for a more accurate and nuanced understanding of how we actually choose our partners.”
Although this study provides new insights into dating psychology, the average reader should be wary of making broad generalizations of the results. One limitation is the use of static photos and written descriptions to simulate dating a rival. Reading profiles on paper cannot fully replicate the intense competitive pressures of real-world social interactions. This lack of real-time pressure may explain why rival profiles did not significantly change most participants’ overall self-perceptions.
“This study was conducted using exposure to rivals through booklets with pictures and descriptions, which is quite different from exposure in real-world situations where you are actually in an environment with rivals and potential romantic partners,” Makhura noted. “Conducting that kind of research is much more complex and was not possible at the time. Therefore, we cannot assume that contact with rivals does not influence our behavior. Nor can we assume that the influence of rivals on partner preferences is controlled solely by an individual’s self-esteem. A wide range of factors may be involved.”
Furthermore, comparing university students and public school students highlights very specific cultural and educational disparities in Brazil. These two groups may have different immediate life goals, such as finding a job right away or pursuing higher education. These different life trajectories can easily influence short- and long-term dating strategies.
While there are many avenues to consider regarding socio-economic status and mate preferences, Makhura has temporarily shifted his attention to other pressing psychological issues.
“For now, my focus is on LGBTQIA+ mental health and whether there is improvement in mental health after participating in potential intervention strategies for these purposes,” she explained. “I would like to return to research in this field in the near future.”
