Studies of the mental processes of chess grandmasters have revealed clues to how people become experts in other fields as well
The preponderance of psychological evidence indicates that experts are made, not born.
Psychologist George Miller of Princeton University famously estimated the limits of working memory–the scratch pad of the mind–in a 1956 paper entitled “The Magical Number Seven, Plus or Minus Two.” Miller showed that people can contemplate only five to nine items at a time. By packing hierarchies of information into chunks, Simon argued, chess masters could get around this limitation, because by using this method, they could access five to nine chunks rather than the same number of smaller details…
The one thing that all expertise theorists agree on is that it takes enormous effort to build these structures in the mind. Simon coined a psychological law of his own, the 10-year rule, which states that it takes approximately a decade of heavy labor to master any field. Even child prodigies, such as Gauss in mathematics, Mozart in music and Bobby Fischer in chess, must have made an equivalent effort, perhaps by starting earlier and working harder than others…
Although nobody has yet been able to predict who will become a great expert in any field, a notable experiment has shown the possibility of deliberately creating one. László Polgár, an educator in Hungary, homeschooled his three daughters in chess, assigning as much as six hours of work a day, producing one international master and two grandmasters–the strongest chess-playing siblings in history. The youngest Polgár, 30-year-old Judit, is now ranked 14th in the world…
Teachers in sports, music and other fields tend to believe that talent matters and that they know it when they see it. In fact, they appear to be confusing ability with precocity. There is usually no way to tell, from a recital alone, whether a young violinist’s extraordinary performance stems from innate ability or from years of Suzuki-style training. Capablanca, regarded to this day as the greatest “natural” chess player, boasted that he never studied the game. In fact, he flunked out of Columbia University in part because he spent so much time playing chess. His famously quick apprehension was a product of all his training, not a substitute for it.
The preponderance of psychological evidence indicates that experts are made, not born. What is more, the demonstrated ability to turn a child quickly into an expert–in chess, music and a host of other subjects–sets a clear challenge before the schools…
