What do people look for in a romantic partner? Everyone has an answer, and the answers vary wildly — until researchers started asking systematically. Across 37 cultures and more than 10,000 people, psychologists found both striking regularities and genuine disagreement in what humans say they want. The science of mate preferences is one of psychology’s most fascinating — and most argued-about — areas.
This article is educational. It summarizes what research finds about the qualities people say they value in partners, where men and women differ on average, and where the scholarly debate stands. It describes group patterns, not prescriptions — no finding here tells you what you should want.

The 37-Culture Study
The landmark study is David Buss’s (1989) survey of mate preferences across 37 samples from 33 countries on six continents — over 10,000 participants in total, making it one of the most ambitious cross-cultural projects in psychology. Participants rated the importance of characteristics in a potential mate: earning capacity, ambition and industriousness, youth, physical attractiveness, chastity, and others.
The headline findings: across cultures, women valued cues to resource acquisition (earning capacity, ambition) more highly than men did, while men valued cues to reproductive capacity (youth, physical attractiveness) more highly than women did. The largest sex differences were in preferred age: in all 37 samples, men preferred younger mates, with the difference statistically significant in every single sample (Buss, 1989).
The evolutionary interpretation: because women historically bore higher obligatory parental investment (pregnancy, nursing), preferring mates who could provide resources was advantageous; because men’s reproductive success depended on partner fertility, cues to youth and health were advantageous. Whether you accept that interpretation or not, the pattern — replicated across 37 cultures — is the finding.
What the Debate Is Actually About
The sex differences are real as averages. The debate is about why they exist — and it is a genuine scientific disagreement, not a settled story:
- The evolutionary account (Buss, 1989; updated in Buss, 2019) holds that the patterns reflect sex-differentiated selection pressures on mating psychology, shaped over deep time.
- The social-role account (Eagly & Wood, 1999) argues the differences reflect the social roles men and women occupy: in societies where men control resources and women are caregivers, each sex rationally values in a mate what their position makes scarce. As gender equality rises, the account predicts, the differences should shrink — and some evidence suggests they do.
- The complications both sides acknowledge: stated preferences don’t always match revealed choices. In a well-known speed-dating study, people’s stated mate preferences failed to predict who they actually desired when they met potential partners face-to-face (Eastwick & Finkel, 2008). What people say they want and what attracts them in person are different things — a finding with obvious implications for dating apps built on stated criteria.
A meta-analysis of gender differences in mate selection preferences found the predicted differences but also emphasized their modest size and the large overlap between the sexes (Feingold, 1992). That overlap point is crucial: even where average differences exist, the distributions overlap enormously. Knowing someone’s sex tells you remarkably little about what that individual wants.
What Both Sexes Agree On
Lost in the debate over differences is the underreported story of similarity. Across cultures, both sexes consistently rank some qualities at the very top: kindness, intelligence, and mutual attraction. These shared preferences dwarf the sex differences in absolute importance — everyone, everywhere, wants a partner who is kind and interesting. The differences researchers argue about are differences in relative emphasis among lower-ranked traits, not disagreements about what matters most.
This is worth remembering whenever pop psychology reduces mate preferences to a battle of the sexes. The science shows far more consensus than conflict — and the consensus is about character.
Attractiveness also carries a halo effect — a person rated highly on one valued quality tends to be rated higher overall.
Culture, Change, and the Modern Context
Preferences aren’t frozen. The 37-culture study itself found striking cultural variation: preference for a mate’s premarital chastity, for instance, ranged from “indispensable” in mainland China to “irrelevant” in Sweden — the most culturally variable preference measured. Economic development, gender equality, and individualism all shift what people prioritize.
Modern dating environments add new wrinkles. Online dating makes stated preferences hyper-visible (filters for height, income, education) while the research suggests stated preferences poorly predict actual attraction (Eastwick & Finkel, 2008) — a tension worth remembering whenever dating profiles are filtered by stated criteria. Assortative mating — the well-documented tendency for similar people to pair up — means that in practice, people mostly end up with partners resembling themselves, whatever their stated ideals.
The popular idea of love languages captures how differently partners express and perceive affection in daily life.
Key Takeaways
- Across 37 cultures (N > 10,000), women on average valued resource cues more and men valued youth/attractiveness cues more; the largest sex difference was in preferred age (Buss, 1989).
- Why the differences exist is genuinely debated: evolutionary accounts vs social-role accounts (Eagly & Wood, 1999) — treat the pattern as established, the explanation as contested.
- Stated preferences often fail to predict actual attraction in live interaction (Eastwick & Finkel, 2008).
- Both sexes agree most on what matters most: kindness, intelligence, and mutual attraction top everyone’s lists.
- Sex differences are averages with enormous overlap — they describe groups, not individuals, and say nothing about what anyone should want.

What do women look for in a partner?
Research on stated preferences finds that, on average across cultures, women rate cues to resource acquisition (earning capacity, ambition) more highly than men do — but kindness, intelligence, and mutual attraction top both sexes’ lists, and individual variation is enormous (Buss, 1989). These are group averages, not descriptions of any individual woman.
What do men look for in a partner?
On average, men rate youth and physical attractiveness more highly than women do, with preferred age showing the largest sex difference across all 37 cultures studied (Buss, 1989). As with women, kindness and intelligence rank at the top for men too — the sex differences are in relative emphasis, not in what matters most.
Are these differences biological or cultural?
Genuinely debated. Evolutionary psychologists argue they reflect sex-differentiated selection pressures; social-role theorists argue they reflect the different social and economic roles men and women occupy, and note the differences shrink as gender equality rises (Eagly & Wood, 1999). The honest answer is that both biology and culture plausibly contribute, and the science hasn’t settled the proportions.
Do people’s stated preferences predict who they’ll actually like?
Often not. In speed-dating research, what participants said they wanted in a partner failed to predict who they were actually attracted to when they met people face-to-face (Eastwick & Finkel, 2008). Live interaction reveals things checklists can’t — which is worth remembering when filtering dating profiles by stated criteria.
Does everyone want the same things in a partner?
More than the debate suggests. Across cultures, kindness, intelligence, and mutual attraction are consistently top-ranked by both sexes. Cultural variation is real (especially on traits like chastity), and individuals vary enormously — but the human consensus on character is the strongest finding in the literature.
