Although it has long been referred to as a mystery, love has just been quantified. Poets and psychologists have been trying to explain why two individuals bond for ages. The study of attraction is now both more comprehensive and remarkably accurate thanks to computers and data analytics. In addition to deciphering human chemistry, academics are redefining compatibility by analyzing millions of dating exchanges.
An ambitious study headed by psychologist Samantha Joel, who collected information from 43 different research studies and nearly 11,000 couples, is at the center of this change. The goal was surprisingly straightforward: to forecast who would be happy in a relationship for the long run. But the outcome was humble. Despite the data’s intricacy, algorithms could not reliably anticipate who would be happy together. What mattered most wasn’t common hobbies or physical attraction, but how pleased each individual already felt before entering the partnership.
Decades of love mythology were reframed by that one realization. It turns out that happiness is a prerequisite for love rather than a result of it. Individuals were much more likely to stay happy in a relationship if they were emotionally satisfied, mentally sound, and self-assured prior. This discovery, which came from sophisticated machine-learning research, supported a long-held belief among therapists that stability and self-awareness are essential components of love rather than extravagance.

One of the oldest romantic clichés, the notion that opposites attract, has also been subtly undermined by big data. People are attracted to partners who are similar to them in terms of education, habits, interests, and even political views, according to large datasets from dating apps like eHarmony and OkCupid. This innate propensity to relate to people who feel familiar is known by researchers as homophily. Both our online and offline decisions are influenced by this innate drive for sameness.
However, data has revealed preferences we frequently ignore in addition to confirming our own. Significant implicit biases in dating behavior, particularly with regard to ethnicity and social background, have been exposed by analytics. For example, even when their profiles indicated openness, women showed a greater preference for same-race messaging behavior. Scientists are reconsidering how honesty, bias, and attraction coexist in the age of swiping because to this discrepancy between declared goals and digital behaviors.
The way people curate themselves online is among the most intriguing aspects of data that are exposed. Although many people make small lies about their age, weight, or height, these lies are typically not very noticeable, according to research from Michigan State and Cornell. They are merely trying to appear their “best selves,” not malicious. It is a presentation exercise and a digital self-branding tool that demonstrates how aspiration and authenticity may coexist. In this way, data reveals our vulnerability as well as our vanity.
Beyond the surface level, big data has been extremely helpful in measuring how attraction evolves once the initial spark fades. Relationship analytics, including communication frequency, shared activities, and message tone, have demonstrated that consistency can increase attraction. Research shows that quality interactions and emotional involvement are better indicators of sustained attraction than initial physical attractiveness, particularly for women. It appears that love thrives not only in initial impressions but also in the ordinary—in routine attention, empathy, and laughing.
The results also imply that contemporary romance has evolved into a window reflecting societal shifts. Dating habits are changing as freedom and equality become more valued in society. Women, previously characterized as favoring security or income, are increasingly drawn to emotional intelligence, humor, and kindness — traits that predict fulfillment more reliably than status. The concept of “marrying up” is giving way to “matching values,” a subtly progressive change that illustrates how emotional literacy has emerged as a new kind of relationship currency.
In the meantime, dating apps have inadvertently turned into social testing grounds. Scientists can see attraction in real time because to the behavioral information that is produced by each swipe, pause, and response. Terms like “authentic connection” and “meaningful conversations,” for instance, surged on popular apps following the epidemic, indicating a general emotional recalibration. Not only did technology document this change, it also influenced it. This increasing desire for emotional depth was discreetly reinforced when algorithms started suggesting more talkative matches over shallow ones.
Nevertheless, forecasting long-term pleasure remains a critical blind spot in data science, despite all of this accuracy. Researchers discovered that although algorithms were able to predict attraction—who would swipe right or respond—they were consistently unable to determine which pairs would remain pleased. It turns out that there was virtually no relationship between long-term fulfillment and the qualities that made someone appealing in the short run, such as charm, wealth, or appearance. These attributes, which Joel dubbed “The Irrelevant Eight,” are highly sought-after but unrelated to enduring love.
This discovery has spurred a more thorough examination of how society views romantic success. We are attracted to things that shine, whether it be prestige, wit, or beauty, yet research indicates that these qualities are merely surface signals. Long-term happiness is much more accurately predicted by shared resilience, kindness, and emotional compatibility. Ironically, the dating economy continues to reward the opposite even as evidence reveals this reality. Algorithms feed our biases by boosting those with the most swipes, the nicest images, or the glossiest lifestyles – measurements that rarely equate with emotional connection.
