1 . A study of violinists found that merely good players practised as much as better players, leaving other factors such as quality of education, learning skills and perhaps natural talent to account for the difference.
This finding challenges the 10, 000-hour rule promoted in Malcolm Gladwell’s 1993 study of violinists and pianists. Gladwell states that enough practice will make an expert of anyone. “The idea has been popular and entrenched in our culture for years. It’s not an idiom but an overstatement,” said Brooke Macnamara, the lead author. “When it comes to human skill, a complex combination of environmental factors and genetic factors explains the performance differences across people.”
Macnamara and her colleagues set out to repeat part of the 1993 study to see whether they reached the same conclusion. They interviewed three groups of 13 violinists regarded as best, good, or less accomplished about their practice habits, before having them complete daily diaries of their activities over a week. While the less skillful violinists reached an average of about 6,000 hours of practice by the age of 20, there was little to separate the good from the best, with each reaching an average of about 11,000 hours. In all, the number of hours spent practising accounted for about a quarter of the skill difference across the three groups.
Macnamara believes practice is less of a driver. “Once you get to the highly skilled groups, practice stops accounting for the difference. Everyone has practised a lot and other factors are at play in determining who goes on to a higher level,” she said. “The factors depend on the skill being learned: in chess it could be intelligence or working memory; in sport it may be how efficiently a person uses oxygen. To complicate matters further, one factor can drive another. Children who enjoy playing the violin, for example, may be happy to practise because they do not see it as a trouble.”
The authors of the 1993 study are unimpressed. Macnamara said it was important for people to understand the limits of practice, though. “Practice makes you better than you were yesterday, most of the time,” she said. “But it might not make you better than your neighhour or the other kid in your violin class.”
