Outliers?

Article on Salon today calling bullshit-ish on Malcom Gladwell's famous 10,000 hour rule:

Yes, the Beatles almost certainly improved as a band after their many hours of playing in Hamburg, particularly because they tended to play the same songs night after night, which gave them the opportunity to get feedback — both from the crowd and themselves — on their performance and find ways to improve it. But an hour of playing in front of a crowd, where the focus is on delivering the best possible performance at the time, is not the same as an hour of focused, goal-driven practice that is designed to address certain weaknesses and make certain improvements — the sort of practice that was the key factor in explaining the abilities of the Berlin student violinists. 

A closely related issue is that, as Lewisohn argues, the success of the Beatles was not due to how well they performed other people’s music but rather to their songwriting and creation of their own new music. Thus, if we are to explain the Beatles’ success in terms of practice, we need to identify the activities that allowed John Lennon and Paul McCartney—the group’s two primary songwriters—to develop and improve their skill at writing songs. All of the hours that the Beatles spent playing concerts in Hamburg would have done little, if anything, to help Lennon and McCartney become better songwriters, so we need to look elsewhere to explain the Beatles’ success.
