Ericsson’s early memory-training studies (with Chase and others) showed ordinary students could expand digit span with designed practice. The 1993 Psychological Review paper with Krampe and Tesch-Römer then logged practice in Berlin music academies and named deliberate practice.
The timeline below follows dated arguments and institutions, not a national myth of genius and not a group ranking.
Origin
1970s–1993 · Sweden / Germany / United States — Ericsson’s early memory-training studies (with Chase and others) showed ordinary students could expand digit span with designed practice. The 1993 Psychological Review paper with Krampe and Tesch-Römer then logged practice in Berlin music academies and named deliberate practice.
Timeline
- Digit-span training
Ericsson, Chase and Faloon train a student (“SF”) to huge digit spans — a proof that “limits” can be method limits.
- Bloom’s talent study
Benjamin Bloom interviews families of high achievers across domains; teachers and parents dominate the story.
- Berlin violin paper
Ericsson, Krampe and Tesch-Römer contrast practice diaries of violinists at different excellence levels.
- Expert-performance approach
The programme spreads to chess, sport and medicine as a methods banner.
- Outliers
Gladwell’s 10,000-hour chapter becomes the global slogan Ericsson mis-recognised.
- Macnamara meta-analysis
Psychological Science paper: practice explains a minority of variance, with domain bands later widely cited.
- Ericsson replies
He argues the meta-analysis mixes ordinary practice with his stricter construct. The dispute is about coding, not about whether hours are magic.
- Hambrick & critiques
Work on working memory, starting age and genes as residual explanations beside practice.
- Howe, Davidson, Sloboda
The Behavioural and Brain Sciences target article argues against innate talent as necessary — a strong nurture pole still cited.
- Ericsson’s death
The research programme continues; the slogan still outruns the papers.
Eras
- Memory-lab era — Limits as methods — Digit span became a demonstration that practice design can move a “capacity”.
- Academy diaries — Hours as data — Berlin violinists made accumulated solitary practice a measurable variable.
- Popular slogan — 10,000 as brand — Gladwell’s threshold escaped every caveat in the 1993 paper.
- Meta-analytic correction — Minority variance — Macnamara 2014 put numbers on “not the whole story”.
- Construct fight — What counts as deliberate — Ericsson versus coders: strict feedback design versus any logged practice.
Shifts
- From talent talk to hour logs 1970s–1993 — Diaries and designed tasks replaced some of the mystique — and created a new mystique of hours.
- From one study to a brand 2008 — A journalist’s chapter out-circulated the Psychological Review article.
- From all-environment to residual 2014– — Meta-analysis and behaviour-genetic critiques restored starting points beside practice.
Deliberate practice: keep the dates visible. Names of talents are younger than the work they try to capture.
