Today’s Wonderful Find; or, Malcolm Gladwell, suck it:
[A] new study in Psychological Science further complicates things. Practice, according to its findings, doesn’t do a great job explaining why some people are better than others at a given skill.
The researchers studied different domains with respect to the impact of practice, and found that while practice accounted for 25% of the differences between athletes, it accounted for a mere 4% in educational performance and bottomed out at 1% in professional success. Which makes me wonder if the benefit of practice is largely about muscle memory vs. any kind of meaningful cognitive gains.
