Ten-Year Rule

The ten-year rule is the empirical finding Gardner documented across all seven creators studied in Creating Minds: genuine creative mastery requires approximately a decade of intensive, focused engagement with a domain before the practitioner has internalized its conventions deeply enough to violate them productively. Picasso mastered classical drawing before Cubism. Stravinsky mastered classical harmony before The Rite of Spring. Einstein spent years working through the foundations of physics before the 1905 miracle year. The rule aligns with deliberate practice research (Ericsson's independent work converged on similar timescales) and provides the empirical ground for this book's argument that AI-mediated acceleration threatens the developmental substrate of creative breakthrough.
