Myths around growth mindset 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

• Growth mindset is proven large — Averages are small Sisk 2018 is the corrective. Some subgroups do better; posters do not.
• The 1998 praise effect always replicates — Li & Bates and others disagree Treat it as a famous design, not a law of nature.
• Mindset replaces teaching — It is a belief about difficulty Ericsson’s designed hour still has to happen.
• Gifted students should be told they are geniuses — Entity giftedness backfires A high ceiling plus incremental theory is the coherent pairing.
• If a child fails, they have a fixed mindset — Systems fail too Load, tracking and access are not personality defects.
• Binet thought IQ was a caste — He thought it was instructional The folklore of fixed IQ is later, and often American.

Worldwide

• United States — District mindset contracts — Post-2006 purchasing boom; Yeager-scale trials tried to put numbers under the posters.
• United Kingdom — Growth-mindset in Ofsted-era talk — Imported vocabulary; evidence fights followed the US literature.
• Australia — School-wide rollouts — Similar consulting wave; local evaluations vary.
• South Korea — Effort culture plus exam gates — A society that already praises hours can still run entity exam identities.
• Finland — Comprehensive years — Late tracking makes “you can still grow” structurally more plausible.
• Japan — 努力 talk and 部活 — Effort is already a moral word; that is not the same as Dweck’s incremental theory of intelligence.

Growth mindset: drop the folklore that ranks groups. Keep the systems that can be named and improved.
