Cultural group selection plays an essential role in explaining human cooperation: a sketch of the evidence.
Open accessAbstract
Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number of explanations for this pattern, including cultural group selection and extensions of more general processes such as reciprocity, kin selection, and multi-level selection acting on genes. Evolutionary processes are consilient; they affect several different empirical domains, such as patterns of behavior and the proximal drivers of that behavior. In this target article, we sketch the evidence from five domains that bear on the explanatory adequacy of cultural group selection and competing hypotheses to explain human cooperation. Does cultural transmission constitute an inheritance system that can evolve in a Darwinian fashion? Are the norms that underpin institutions among the cultural traits so transmitted? Do we observe sufficient variation at the level of groups of considerable size for group selection to be a plausible process? Do human groups compete, and do success and failure in competition depend upon cultural variation? Do we observe adaptations for cooperation in humans that most plausibly arose by cultural group selection? If the answer to one of these questions is “no,” then we must look to other hypotheses. We present evidence, including quantitative evidence, that the answer to all of the questions is “yes” and argue that we must take the cultural group selection hypothesis seriously. If culturally transmitted systems of rules (institutions) that limit individual deviance organize cooperation in human societies, then it is not clear that any extant alternative to cultural group selection can be a complete explanation.

TL;DR
Richerson et al. argue that cultural group selection (CGS) is an essential and empirically plausible explanation for human cooperation among non-relatives, drawing on evidence from five domains. They conclude that culture acts as an inheritance system, group-level cultural variation is substantial, groups compete, and group-functional adaptations exist, though quantitative estimates of CGS strength remain incomplete.
Key findings
- Culture acts as an inheritance system: developmental evidence shows imitation and teaching emerge in the first 12 months, and historical/linguistic data show phylogenetic descent with modification; in Tupi cultural domains, rates were usually less than five transitions in 10 millennia.
- Cultural F_ST between neighboring groups is consistently greater than 0.01, with some traits above 0.6; for neighboring groups that might compete, cultural F_ST is approximately an order of magnitude larger than genetic F_ST.
- Intergroup competition is documented: among the Turkana, 1% of male mortality is from within-Turkana violence versus 50% from inter-ethnic raids; average raids include 315 men, with some up to 1,000; large-scale warfare can involve mostly unrelated individuals (e.g., Stalingrad involved more than 1.7 million soldiers and over two million casualties).
- Group-functional institutions and religion show effects: costly ritual displays correlate with commune longevity across more than 800 U.S. communes over 200 years; Soltis et al. estimated group extinction rates could spread a group-beneficial cultural trait to most of a metapopulation in 500–1,000 years.
Methods
- The target article is a synthetic review or “sketch” of evidence from five domains: culture as an inheritance system, group-level cultural variation, intergroup competition, group-level functionality, and gene-culture coevolution.
- Quantitative component: cultural F_ST was calculated from survey responses (World Values Survey, AfroBarometer, Public Policy Institute of California surveys, Scottish Health Survey, Anwar Sadat Chair Arab Public Opinion Surveys, among others) for neighboring political, religious, ethnic, geographic, and socioeconomic groups; the Price equation was used to express conditions for group selection.
- Evidence is drawn from developmental psychology, historical linguistics and phylogenetics, ethnography, archaeology, economic organization, religion, and warfare.
Limitations
- The paper states it cannot provide a precise quantitative account of CGS importance relative to competing processes; too few quantitative studies exist, and direct evidence for culture-led gene-culture coevolution is strong only for genes that do not directly affect behavior.
- The paper notes uncertainty about how similar modern foragers are to Pleistocene foragers and that direct evidence for Pleistocene warfare is very limited.
- The text makes evident that cultural F_ST from ethnographic data is often impossible because ethnographers typically report only normative behavior and neglect individual variation; the survey-based F_ST estimates also rely on group classifications that may not capture heritable cultural variation or cooperation-relevant traits.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
