Myths around nature and nurture travel faster than papers. Each item pairs a folklore line with a tighter claim.

Worldwide notes name real systems — 영재교육, 예고, 部活, CTY, AIS, Iten — as places and policies, not racial essences.

Myth cards + sources

Four teaching cards with citations. Forbidden: group IQ by ethnicity, race or nation.

Myth 10,000 hours is a universal law

Tighter claim: Gladwell slogan ≠ Ericsson’s study design

The 1993 violinist comparison did not issue a universal hour ticket for every domain.

Source Ericsson, Krampe & Tesch-Römer (1993); Gladwell (2008) popularisation

Myth Practice alone explains excellence

Tighter claim: Practice is necessary, rarely sufficient

Meta-analyses find practice explains a minority of performance variance across domains.

Source Macnamara, Hambrick & Oswald (2014)

Myth Talent is fixed by group identity

Tighter claim: Forbidden: group IQ / racial rankings

This atlas teaches pathways and practice design — never essentialist rankings of peoples.

Source Editorial policy — Tool-Lifes talent atlas (no group IQ)

Myth Any repetition counts as deliberate practice

Tighter claim: Design + feedback is the construct

Playing favourites is not the same variable as weakness-targeted, coached work.

Source Ericsson & Harwell (2019) on deliberate-practice criteria

Myths

• Talent is all born — Development is interaction Even highly heritable traits move with training, health and access.
• Talent is all taught — Starting points differ Practice explanations still leave residual differences. Ericsson never measured a blank slate.
• Heritability is destiny — It is a variance split Change the environment’s range and the coefficient can move.
• Twin studies rank races — They do not Classic designs compare relatives inside populations. Between-group stories are a different, confounded question.
• A genius gene is coming — Traits are polygenic Thousands of tiny effects plus environment. No concert-pitch allele to swab at birth.
• Galton is just quaint — His ranking project had victims The slogan outlived the eugenic programme; the harm did not vanish by being old.

Worldwide

• United Kingdom — Grammar and specialist schools — Selection by exam still encodes opportunity. Galton’s country never stopped arguing about early gates.
• United States — SMPY and CTY searches — Julian Stanley’s talent search used above-level SAT, not a nature-only story — but access still tracks who hears about the test.
• South Korea — 영재교육 centres — State gifted programmes sit on a huge private-tutor market. “Nurture” here is an industry.
• Finland — Late tracking, teacher trust — A high-trust comprehensive years delays hard sorting — an environmental bet on breadth.
• Japan — 部活 club culture — After-school clubs supply hours that look like “passion” and are also institutional nurture.
• Kenya / Ethiopia — Altitude running towns — Iten and Bekoji show how place, labour and training culture co-produce world times — not a racial essence.

Nature and nurture: drop the folklore that ranks groups. Keep the systems that can be named and improved.
