Deliberate practice in : From talent talk to hour logs

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.
