David Buss

Who he is

David Buss is an American psychologist, born in 1953, who is widely regarded as one of the founders of evolutionary psychology. ^[3] He directs an evolutionary psychology lab at the University of Texas at Austin, where his research centres on human mating strategies and conflict between the sexes, and he wrote the discipline's standard textbook, Evolutionary Psychology: The New Science of the Mind. ^[4]

He is best known for a single landmark study. In 1989 he published a survey of 10,047 people drawn from 37 samples across 33 countries, testing whether men and women differ in what they say they want in a partner. ^[1] He turned that work into a general-audience book, The Evolution of Desire, in 1994, which remains the reference text for the idea that human attraction has an evolved architecture. ^[2] None of this began as a commentary on internet subcultures. Buss is a mainstream academic whose findings predate the manosphere by decades and who has never been part of it.

What his research actually found

The 1989 study reported consistent, cross-cultural sex differences in stated preferences. On average, women rated a prospective mate's earning capacity and resources more highly than men did, and men rated youth and physical attractiveness more highly than women did. ^[1] These differences were reliable in direction across very different societies, which is what made the paper influential.

Three qualifiers travel with that result and are routinely dropped when it is repeated. First, the study measured what people say they value on a questionnaire, not who they actually partner with. Second, the sex differences are differences of degree in how highly each trait is ranked, not evidence that either sex ignores the other's priorities. Third, the size of the differences is not fixed: later cross-national work found that these gaps shrink as a country becomes more gender-equal, which is difficult to reconcile with the idea that they are hard biological constants. ^[5] Buss's data show a real average tendency; they do not show an iron law.

Why the manosphere cites him

Buss's findings are the academic ancestor of the red-pill vocabulary of "hypergamy," "sexual market value" and "the wall." The manosphere reads his average sex difference in resource preference as proof of hypergamy, treats his average male preference for youth as the biological basis of the wall, and compresses the whole picture into a scoreboard of sexual market value.

Each step adds something Buss did not report. A modest, culture-variable average difference becomes an absolute law that governs every woman. A stated preference becomes a prediction about behaviour. A group average becomes a verdict on individuals, so that a particular woman is said to be destined to "marry up" and a particular man is told his rank is fixed. And a description of tendencies becomes a prescription for how people ought to date. The gap between Buss's paper and the ideology is not a matter of emphasis; it is the difference between a statistical finding and a fatalistic worldview.

His engagement with this world

Buss has not built a public career around the manosphere, and this reference does not claim he has issued a general denunciation of it, because no such statement could be verified for this page. His most direct documented engagement is scholarly. With William Costello, a doctoral researcher in his lab, he co-authored a 2023 paper arguing that although incel communities are saturated with misogynistic rhetoric, actual violence by incels is statistically rare, and framing incel distress partly as an evolutionary mismatch between the small ancestral groups our mating psychology evolved for and the anonymity of modern dating. ^[7] Related work led by Costello found that self-identified incels reported markedly higher depression, anxiety and loneliness than comparison men, a framing oriented toward support rather than only condemnation. ^[8]

His 2021 book When Men Behave Badly points the same evolutionary lens at male sexual deception, harassment and assault. ^[3] That is a notable direction of travel, because it treats male misconduct as the thing to be explained, which cuts against the victimhood narrative the manosphere tends to draw from the same science.

The scientific debates

Buss's account is influential but contested, and the disagreements are ordinary science rather than manosphere talking points. The main rival is social-role theory, associated with Alice Eagly and Wendy Wood, which argues that sex differences in mate preferences arise from the social division of labour and gender roles rather than from evolved dispositions alone, and which reanalysed Buss's own 1989 data to support a social-structural reading. ^[6] The cross-national finding that preference gaps shrink as gender equality rises has been read by some researchers as evidence against a purely evolved explanation. ^[5]

That evidence is genuinely disputed among specialists, with critics arguing that some preference differences persist or even widen in more equal societies, and that the picture depends heavily on which preference is measured. The honest summary is that Buss documented a real and replicated average pattern, that its causes and its stability across cultures remain open scientific questions, and that neither the field's internal debates nor Buss's own findings support the certainty the manosphere projects onto them.
