Designed, feedback-rich practice — Ericsson’s violinists, not Gladwell’s 10,000-hour slogan. Deliberate practice is K. Anders Ericsson’s name for work that is designed, effortful, feedback-rich and aimed at weaknesses — not hours of pleasant repetition.
Malcolm Gladwell’s Outliers (2008) popularised “10,000 hours” as a threshold. Ericsson’s Berlin violin study never claimed that any domain yields to a single hour count, and he later objected to the slogan.

Brooke Macnamara, David Hambrick and colleagues’ 2014 meta-analysis found that deliberate practice explains a minority of variance in performance: about 26% in games, 21% in music, 18% in sports, 4% in education. Those are rounded published bands, not a new folk number.
Across domains, deliberate practice accounted for a minority of performance variance — roughly 26% games, 21% music, 18% sports, 4% education in their coding. A minority of variance can still be the largest controllable lever. It does mean practice is not the whole story — Howe, Hambrick and others have pressed this against strong environmentalism.
This is about practice and individual craft. It is not a group IQ score. It does not replace the full topic page.
