The New York Times has a column by the authors of Freakonomics:
Anders Ericsson, a 58-year-old psychology professor at Florida State University,…. is the ringleader of what might be called the Expert Performance Movement, a loose coalition of scholars trying to answer an important and seemingly primordial question: When someone is very good at a given thing, what is it that actually makes him good?
Ericsson and his colleagues have thus taken to studying expert performers in a wide range of pursuits, including soccer, golf, surgery, piano playing, Scrabble, writing, chess, software design, stock picking and darts. They gather all the data they can, not just performance statistics and biographical details but also the results of their own laboratory experiments with high achievers.
Their work, compiled in the “Cambridge Handbook of Expertise and Expert Performance,” a 900-page academic book that will be published next month, makes a rather startling assertion: the trait we commonly call talent is highly overrated. Or, put another way, expert performers — whether in memory or surgery, ballet or computer programming — are nearly always made, not born. And yes, practice does make perfect. These may be the sort of clichs that parents are fond of whispering to their children. But these particular clichs just happen to be true.
