Why Algorithms Can't Predict Your Love Life

The internet wants you to believe you're a six out of ten. That your romantic destiny hinges on your jawline, your salary, and whether you can land someone in your "league." According to Dr. Paul Eastwick, a psychologist who studies human mating, this entire framework is scientifically bankrupt — and it's making us all miserable.

In this episode of The Happiness Lab, Yale professor Dr. Laurie Santos sits down with Eastwick to dismantle what he calls the "evoscript" — the harsh, pseudoscientific ideas about attraction that dominate online dating culture. His new book, Bonded by Evolution: The New Science of Love and Connection, offers a radically different picture: one where compatibility matters far more than consensus hotness, where friendships matter more than pickup lines, and where patience beats swiping.

The Mate Value Myth

The evoscript starts with a deceptively simple idea: everyone has a "mate value" — a numerical ranking determined by attractiveness, earning potential, youth, or status. According to this worldview, dating is a marketplace where nines date nines and threes settle for threes.

Eastwick traces this thinking to two observations: people somewhat agree on who's attractive when shown photos, and existing couples tend to have similar attractiveness levels. But his research reveals these correlations are far weaker than pop psychology suggests.

"Most of the faces that participants were evaluating — ninety-six percent of them — somebody rated you in the top half or in the bottom half. So that means that only for four percent of the faces did everybody agree."

In other words: almost everyone is someone's type. The consensus component of attraction exists, but it's dwarfed by individual taste — what researchers call "compatibility."

Even more striking, Eastwick found that this consensus component shrinks over time. When people meet as strangers, the conventionally attractive have an advantage. But after weeks of getting to know each other — like at summer camp — "anything can happen." The popular kids lose their universal appeal, and the initially overlooked find devoted admirers.

Gender Differences Are Overblown

The second pillar of the evoscript is that men and women want fundamentally different things: men want beauty, women want resources. Survey data has long supported this — men consistently rate physical attractiveness as more important, while women prioritize earning potential.

But Eastwick's speed-dating research tells a different story. When you measure revealed preferences — how people actually respond to real humans, not abstract surveys — the gender differences vanish.

Women do like ambitious men slightly more at speed-dating events. But here's the twist: so do men. Men also prefer ambitious women, and their revealed preference for ambition is "exactly the same" as women's. The same pattern holds for physical attractiveness. Both men and women strongly prefer attractive partners, with no meaningful gender difference.

This matters because the "alpha versus beta" framework online is built on these supposed differences. The trad wife culture, the redpill forums, the endless gender wars — they're predicated on distinctions that don't show up when you actually watch people date.

The Short-Term/Long-Term Fallacy

The third myth is that people are either short-term sexy types or long-term relationship material — never both. Online, this becomes the alpha/beta dichotomy: the sexually desirable man who racks up conquests versus the stable provider who women "settle" for.

Eastwick's verdict? "Pretty much everything else about this idea is way off base." Yes, being sexy and confident correlates with more sexual partners. But there's zero evidence that short-term desirability predicts long-term relationship failure. The guy with the longer sexual resume isn't doomed to divorce, and the "nice guy" isn't inherently better relationship material.

What Actually Matters: Creative Chaos

If mate value, gender scripts, and alpha/beta hierarchies don't predict romantic success, what does?

Eastwick's answer: compatibility, which he describes as "creative chaos." It's not about similarity — his research found that matching people on personality traits, values, even deal-breakers barely predicts who clicks. Instead, compatibility is built through repeated interactions.

"We have to engage other people in series of interactions and kind of see what it is that we can bond over. And the number of things that people can bond over, in principle, is very, very long."

This explains why dating apps struggle. Algorithms can predict whether you are generally selective or generally popular, but they can't predict which specific pairs will work. Dr. Samantha Joel ran massive machine-learning studies with troves of pre-date data and "was able to predict absolutely nothing" about who would match.

The problem isn't the algorithms — it's that compatibility emerges through time and luck. Two people hit on a random shared interest, build from there, and after "a thousand" such interactions, they've created something real.

Dating in the Age of Infinite Choice

This temporal element is precisely what online dating short-circuits. We expect sparks immediately, bail after bad first impressions, and face choice overload that makes every match feel replaceable.

Eastwick's advice? "Try to date from a larger pool of folks. Try to open up the aperture a little bit for who you're willing to consider, and be willing to give people a second or a third chance."

Better yet: spend more time in environments where you naturally encounter the same people repeatedly. Intramural sports leagues, cooking classes, friend-of-friend gatherings — the "lost art" of hanging out. Historically, this is how humans found partners: not through stunning first impressions but through accumulated interactions in communities.

Embrace the Friend Zone

Perhaps Eastwick's most counterintuitive finding: being friends with potential romantic interests is good, actually.

The "friend zone" — originally from Friends and Ross's pining for Rachel — has been weaponized online as a trap that "nice guys" must avoid. But Eastwick's research shows that people with mixed-gender friend groups are more likely to find romantic partners, often through those friends' networks.

"Men and women can be friends just fine," he says. The whole framework of avoiding platonic relationships with the opposite sex is "a disastrous approach."

A More Hopeful Science

What makes this research genuinely liberating is its optimism. You're not stuck with your mate value. Your romantic prospects aren't determined by your jawline or your paycheck. You can be compatible with far more people than you think — you just need time, patience, and repeated exposure.

The work isn't crafting the perfect Tinder bio. It's showing up, socializing, letting your network expand, and trusting that serendipity will strike.

As Eastwick reflects on his own single years: "I stopped being so focused on exactly where the prospects were, and things really started to change after that point. And it's not because I developed these new special attributes and now I had higher mate value. I just had this expanding social network."

The Verdict: This episode is essential listening for anyone who's felt demoralized by modern dating culture. Dr. Laurie Santos and Paul Eastwick dismantle toxic dating scripts with rigorous science and replace them with something rare in this space: genuine hope. The core insight — that compatibility is built, not discovered — is both challenging and freeing. If you're exhausted by apps or drowning in online dating nihilism, this conversation offers a research-backed path forward. Just don't expect a quick fix. Eastwick's message requires patience, community, and a willingness to hang out without an agenda. But if the alternative is rating yourself on a ten-point scale and hoping the algorithm finds your soulmate, his approach sounds a lot more human.
