Myths around polymaths 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
