Origin
1870s · Britain — Galton’s 1874 phrasing “nature and nurture” popularised a binary that breeders and philosophers already knew. His Hereditary Genius (1869) mixed pedigree tables with a programme of ranking that later eugenics abused.
Timeline
- Hereditary Genius
Galton argues eminence runs in families and treats reputation as a proxy for ability — a method later criticised as circular.
- English coinage
Galton’s “nature and nurture” becomes the public slogan for the contrast.
- Spearman’s g
Charles Spearman extracts a general factor from test intercorrelations; the statistic is not a racial ranking.
- Burks & adoption
Barbara Burks’s California adoption work tries to separate home from pedigree — early, imperfect, still a design step.
- Vygotsky’s zone
Lev Vygotsky’s zone of proximal development treats what a child can do with help as the educational unit, not a fixed IQ.
- Skinner vs Chomsky
Radical environmentalism in behaviourism meets nativist arguments about language — a fight about mechanism, not school ranking.
- Minnesota twins
Thomas Bouchard’s Minnesota Study of Twins Reared Apart becomes the late-century media emblem of genetic influence.
- Plomin & G×E
Robert Plomin and others push heritability plus gene–environment interplay as the default developmental frame.
- Human genome era
Cheap genotyping raises hopes of “talent genes”; most complex traits prove highly polygenic and environment-sensitive.
- Missing heritability
GWAS hits explain less variance than twin estimates. The gap is a methods story, not proof that genes vanished.
Eras
- Pedigree era — Eminence as inheritance — Victorian tables of “great men” treated reputation as a biological fact and ignored who was allowed to become eminent.
- Test era — Psychometrics arrives — Spearman, Binet and later Wechsler built instruments. Binet’s original brief was to find children who needed help, not to crown a caste.
- Behaviourist pause — Environment as engineering — Watson’s boast that he could train any infant was a polemic, not a dataset. It still shaped mid-century schooling rhetoric.
- Behavioural genetics — Twins and adoptions — MZ/DZ and adoption designs dominated late-century claims about cognitive traits in WEIRD samples.
- Genomic present — Polygenic scores — Scores predict modestly inside some populations and travel badly across ancestries — a reason this page refuses group league tables.
Shifts
- From binary to interaction 1874–1990s — The public still hears either/or; the journals moved to reaction norms, correlation and interaction.
- From pedigree to design 1900–1980 — Anecdote families gave way to twins, adoptions and, later, molecular data — each with new confounds.
- From ranking project to development 1980–present — Developmental science asks how skill is built over time, not which nation “wins” a test.
Nature and nurture: keep the dates visible. Names of talents are younger than the work they try to capture.
