A new Science review synthesizes research on over 34,000 world-class performers in science, music, chess, and sports. The study finds that young exceptional performers and later adult champions are largely different people. Early stars often master one discipline intensely, while top adults typically had broader, multidisciplinary backgrounds with slower initial progress.

This challenges the common assumption that early talent directly predicts adult greatness. Elite youth programs often select for early specialization, but the evidence suggests this may not be the optimal path for reaching the highest adult performance levels. The patterns hold across diverse domains, from Nobel laureates to Olympic champions.

The findings point to new explanatory hypotheses, like search-and-match or enhanced-learning-capital. For educators and program managers, this suggests rethinking talent identification and training models. Future research will test these principles, potentially reshaping how we cultivate expertise in science, sports, and the arts.
