In certain fields of human endeavor, such as music, chess, and some athletic activities, the performance of the best practitioners is so outstanding, so superior even to the performance of other highly experienced individuals in the field, that some people believe some notion of innate talent must be invoked to account for exceptional athletic performance, including superior motor coordination, speed of reflexes, and hand-eye coordination, can be inborn.
Until recently, however, little systematic research was done on the topic of superior performance, and previous estimates of the heritability of traits relevant to performance were based almost exclusively on random samples of the general population rather than on studies of highly trained superior performers as compared with the general population. Recent memory for configurations of chess pieces, but only if those configurations are typical of chess games.
The vast majority of exceptional adult performers were not exceptional as children, but started instruction early and improved their performance through sustained high-level training. Only extremely rarely is outstanding performance achieved without at least ten years of intensive, deliberate practice. With such intensive training, chess players who may not have superior innate capacity and the percentage of muscle fibers, show specific changes that develop from extended intense training.
The evidence does not, therefore, support the claim that a notion of innate talent must be invoked in order to account for the difference between good and outstanding performance, since it suggests instead that extended intense training, together with that level of talent common to all reasonably competent performers, may suffice to motivational factors are more likely to be effective predictors of superior performance than is innate talent.
