Science of Attraction: Why Dating Apps Are Lying to You

Most of what you believe about attraction — who wants what, and why — turns out to be wrong, and the data proving it has been sitting in peer-reviewed journals for years.

Men and women show nearly identical preferences for younger partners, flipping a long-held stereotype on its head.
Dating apps create a distorted picture of attraction that almost disappears in real-world settings.
Compatibility cannot be predicted from a profile — it only emerges through actual interaction.
Couples who see each other as uniquely special — even unrealistically so — build more lasting relationships.

The Stereotype That the Data Keeps Killing

Pop psychology has sold one story for decades: men chase youth, women chase wealth. It makes for clean headlines. It does not make for accurate science. Dr. Paul Eastwick, a psychology professor at the University of California Davis, has spent his career testing these claims in controlled studies. His finding is blunt. When it comes to age preference, “in study after study those gender differences are reliably zero,” Eastwick said during a 2024 appearance on the Huberman Lab podcast. Both men and women, when given a real choice, tend to pick partners who are younger than they are.

The wealth finding is just as surprising. Men and women value financial status in a partner at nearly the same level in practice. The gender gap that looks so large in surveys shrinks close to nothing when researchers study real attraction between real people. The gap between what people say they want and what actually draws them in is one of the most consistent findings in modern relationship science.

Why Dating Apps Are Lying to You

Dating apps filter partners by traits — age, height, income, photos. That approach feels logical. The data says it mostly fails. Women on dating apps swipe yes on roughly 5 percent of men. Men swipe yes on about 50 percent of women. That is a staggering gap. But here is the twist: that extreme difference nearly disappears in real social settings. The app creates an artificial environment that amplifies snap judgments and hides the actual ingredients of attraction.

Eastwick argues that compatibility is the core driver of lasting love, and compatibility is “notoriously difficult to forecast” from a profile alone. A photo and a list of hobbies cannot capture the specific chemistry two people generate when they are actually in the same room. His advice, echoed in his book Bonded by Evolution, is to give most people at least three real interactions before deciding whether to move on. One awkward coffee does not tell you much.

The Hook Nobody Talks About

So if traits do not predict long-term attraction, what does? Eastwick points to something he calls idiosyncratic hooks — the specific, hard-to-name qualities that make one person uniquely compelling to another. These are not things you can list on a profile. They show up in how someone laughs, how they handle a bad day, how they make you feel mid-conversation. Lab studies back this up. When people evaluated written profiles, they preferred partners whose listed traits matched their stated ideals. But after a live interaction, that trait-matching effect vanished. The real person overrode the checklist every time.

Physical intimacy also plays a larger role than most people admit. Research discussed in the Huberman Lab episode points to physical closeness as one of the strongest predictors of relationship stability over time. This is not just about early attraction. Maintaining physical connection appears to anchor the bond as the relationship matures and the initial rush of novelty fades.

The Power of Seeing Your Partner as One-of-a-Kind

One of the more counterintuitive findings in this research involves what Eastwick calls positive bias. Couples who believe their partner is more wonderful than anyone else — even when outside observers might disagree — tend to stay together longer. These are not delusions in a harmful sense. They are a kind of chosen focus, a decision to keep seeing your partner as irreplaceable. Relationships where both people carry that bias are measurably more stable than those where partners size each other up against the wider dating pool.

This matters because modern dating culture pushes the opposite mindset. Apps are built on the assumption that a better option is always one swipe away. That mental posture, research suggests, is corrosive to commitment. The couples who last are not the ones who found a perfect match on paper. They are the ones who built a shared story — and decided it was worth protecting.
