The Magic Number for Real Expertise

The ten thousand our rote was invented by malcolm gladwell, who stated that researchers have settled on what they believe is the magic number for true expertise. Gladwell cited our research on expert musicians as a stimulus for his provocative generalization to a magical number. The best violinist reported having spent a remarkably large number of hours engaged in solitary practice - when in fact, ten thousand hours was the average of the best group. Most of the best musicians had accumulated substantially fewer hours of practice at the age 20. In contrast, gladwell does not even mention the concept of deliberate practice.
