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

Valentine’s Day often stirs the temptation to believe that "The One" exists somewhere in the world—a destined partner, a perfect match, or a soulmate with whom we were meant to share our lives. Throughout history, humanity has resisted the notion that love is merely random chance.

In ancient Greece, Plato proposed a famous myth suggesting that humans were originally complete beings, possessing four arms, four legs, and two faces. So radiant were these primordial creatures that Zeus split them in two. Since that separation, each half has wandered the earth in search of its missing other. This narrative provides the modern concept of the soulmate with its poetic roots, offering the promise that someone out there will ultimately make us feel whole.

During the Middle Ages, this longing was reframed as "courtly love" by troubadours and Arthurian legends. This intense, often forbidden devotion, exemplified by Lancelot’s love for Guinevere, required knights to prove their worth through self-sacrifice for a beloved they might never publicly claim. By the Renaissance, authors like Shakespeare popularized the idea of "star-crossed lovers"—couples bound by an overpowering connection but separated by external forces such as family dynamics, fortune, or fate, as if the universe itself authored their romance while simultaneously blocking their path to happiness.

In more recent eras, Hollywood and romance novels have perpetuated the fairy-tale narrative. However, what does contemporary science reveal about the existence of soulmates? Is there truly a specific individual predestined for each of us?

The Evolution of Romantic Ideals

Viren Swami, a Professor of Social Psychology at Anglia Ruskin University (ARU) in Cambridge, traces the modern European understanding of romantic love back to medieval Europe and the tales of Camelot. He notes that stories involving Lancelot, Guinevere, and the chivalry of the Knights of the Round Table swept across the continent, fundamentally shifting societal views.

"These stories first pushed the idea that you should choose one other individual as your companion and that companion is for life," Swami explains. "Before that, in much of Europe, you could love as many people as you like, and love was fluid, and it was often not about sex."

Swami argues that as industrialization dismantled traditional agricultural communities and uprooted people from familiar social structures, individuals became "alienated." Consequently, they began seeking a single person to rescue them from the hardships of life. Today, this narrative has been transformed by dating apps into an algorithmic process that Swami describes as "relation-shopping."

Paradoxically, the search for a soulmate often yields the opposite result. "For many people, that's a really soulless experience," Swami 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

Jason Carroll, a Professor of Marriage and Family Studies at Brigham Young University in Provo, Utah, understands the deep human desire for "The One." "We are attachment-based creatures," he says. "We desire that bond."

However, Carroll advises students to abandon the concept of a "soulmate" without sacrificing their hope for a lifelong partner. While this may seem contradictory, Carroll distinguishes between destiny and effort. "A soulmate is just simply found. It's already pre‑made. But a one and only is something two people carve out together over years of adapting, apologising, and occasionally gritting their teeth," he asserts.

The Soulmate Trap

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

Research led by Professor C. Raymond Knee at the University of Houston, widely cited from the late 1990s and early 2000s, found that individuals who believed relationships were "meant to be" were significantly more likely to question their commitment when facing conflict. Those with a growth-oriented mindset, conversely, tended to view challenges as opportunities for development.
