Science Debunks the 'Opposites Attract' Myth in Relationships
For centuries, the idea that 'opposites attract' has been a staple in storytelling, from classic literature to modern romantic comedies, often depicting unlikely pairings like a nerdy individual falling for the most attractive person in a setting. However, scientific research now suggests this concept might be better suited to fiction than real life. A study from the University of Missouri, published in Science Advances, indicates that relationships thrive when partners have similar levels of desirability.
Research Findings on Attraction and Desirability
The researchers discovered that individuals with comparable 'mate values'—a measure of how desirable someone is perceived as a partner—are more likely to enter into relationships and experience greater success within them. To investigate this, Sean Prall, an assistant professor of anthropology, conducted fieldwork in northwest Namibia, focusing on the Himba community, a semi-nomadic agro-pastoralist group. By interviewing community members, Prall estimated mate values and analyzed relationship statuses, finding that couples with similar scores had better outcomes.
Prall emphasized that this study differs from prior research by examining actual behavior rather than stated preferences. "Much anthropological work on human mating patterns relies on people's preferences, which are influenced by societal norms," he explained. "We focused on actions: what people do in relationships and how those relationships actually progress." This approach provides a more accurate picture of real-world dynamics.
Real Behavior Versus Stated Preferences in Human Mating
Before the COVID-19 pandemic in 2019, Prall and his colleague Brooke Scelza, a professor at UCLA, spent over a month each summer living with the Himba to study human behavior. Over five years, they collected data on various aspects, including:
- Marriage patterns
- Parenting decisions
- Child health
- Food insecurity
- Partner selectivity
Although much of this research is specific to the Himba population, Prall believes the findings have broader implications. "This community was ideal because everyone knows each other, and most dating and marriage occur within the group," he noted. "This mirrors how humans have partnered for millennia—through community connections, not online platforms." The study highlights that in real-life settings, similarity in desirability plays a crucial role in relationship formation and success, challenging the romanticized notion of opposites attracting.
