Malcolm Gladwell read our work, and he misinterpreted some of our findings. We [studied] violinists who had been at an international academy [and were] viewed as being on track for international careers. When we estimated how many hours they had spent working on trying to improve their performance by themselves, we came up with an average, across the group, of 10,000 hours. But that really meant that there was a fair amount of variability. I would argue that the key thing that people have misinterpreted is that it’s not just a matter of accumulating hours. If you’re doing your job, and you’re just doing more and more of the same, you’re not actually going to get better. There’s a lot of research to really prove that.
