The Science of Soulmates: Is There a Perfect Match Waiting for You?

Valentine’s Day often stirs the desire to believe that a singular, destined partner exists—someone who is "The One," a soulmate, or a perfect complement. This belief that romance is not merely random has deep historical roots. In ancient Greece, Plato proposed that humans were originally complete beings with four limbs and two faces. According to the myth, Zeus split them in half, condemning each part to wander the earth seeking its missing counterpart. This narrative established the poetic foundation for the modern concept of the soulmate, suggesting that true completion is found in another person.

During the Middle Ages, this longing was reimagined as "courtly love" in troubadour poetry and Arthurian legends. Stories like that of Lancelot and Guinevere portrayed love as an intense, often illicit devotion where a knight demonstrated his virtue through self-sacrifice for a lady he might never openly claim. By the Renaissance, authors such as Shakespeare popularized the notion of "star-crossed lovers"—couples bound by an overpowering connection but thwarted by external forces like family, fate, or fortune, implying that the universe both orchestrated and obstructed their union.

In contemporary culture, Hollywood and romance novels have perpetuated these fairy-tale narratives. However, scientific inquiry offers a different perspective: does a unique, pre-destined partner actually exist for everyone?

The Evolution of Romantic Ideals

Viren Swami, a Professor of Social Psychology at Anglia Ruskin University in Cambridge, traces the modern European concept of romantic love back to medieval traditions, specifically the chivalric tales of Camelot involving Lancelot and Guinevere. "These stories first pushed the idea that you should choose one other individual as your companion and that companion is for life," Swami explains. He notes that prior to this shift, love in much of Europe was fluid, often unrelated to sex, and allowed for multiple partners.

Swami argues that industrialization disrupted this stability by uprooting people from agrarian communities and severing familiar social ties. This alienation led individuals to seek a single partner to rescue them from the hardships of modern life. Today, dating apps have transformed this search into a process Swami terms "relation-shopping." He warns that this algorithmic approach can be disheartening. "For many people, that's a really soulless experience," he says. "You're shopping for a partner… going through possibly dozens of people on the dating app until you get to a point where you go… I need to stop."

Destiny vs. Graft

While the allure of "The One" remains strong, Jason Carroll, a Professor of Marriage and Family Studies at Brigham Young University in Provo, Utah, offers a nuanced view. Acknowledging that humans are "attachment-based creatures" who deeply desire bonding, Carroll advises students to discard the concept of the soulmate while retaining the goal of finding a lifelong partner.

For Carroll, the distinction lies between destiny and effort. "A soulmate is just simply found. It's already pre‑made," he says. In contrast, a "one and only" is constructed through mutual effort. "It's something two people carve out together over years of adapting, apologising, and occasionally gritting their teeth."

The Soulmate Trap

Carroll’s perspective is supported by decades of psychological research, summarized in his report, The Soulmate Trap. The report differentiates between "destiny beliefs"—the expectation that a compatible relationship should require no effort—and "growth beliefs," which emphasize the actions partners take to sustain their bond.

Research led by Professor C. Raymond Knee at the University of Houston in the late 1990s and early 2000s highlighted the risks of the former mindset. The studies found that individuals who believed relationships were "meant to be" were significantly more likely to question their commitment when facing conflict. Conversely, those with a growth-oriented mindset viewed challenges as opportunities to strengthen their partnership.
