q2 · i? · review · r2

Review of longitudinal assessments and retrospective evidence on expert development. The article reports that Simon and Chase originally proposed the 10-year rule for chess and that "even the most “talented” need around 10 years of intense involvement" before international level.

"even the most “talented” need around 10 years of intense involvement before they reach an international level; for most individuals, it takes considerably longer."
