10000 hours

What does it take to become an expert or master performer in a given field? Ericsson says the rule is an oversimplification, and in many ways, an incorrect interpretation of his research. The 10, Hour Rule: Catchy and easy to remember, but on some pretty shaky scientific footing. Gladwell uses several examples in his book when introducing this rule: one is the research done by Ericsson that focused on violin students at a music academy in Berlin. The study found that the most accomplished of the students had put in 10, hours by the time they turned Gladwell also estimates that the Beatles put in 10, hours of practice playing in Hamburg in the early s, and that Bill Gates put in 10, hours of programming work before founding Microsoft. Hence the 10, hour rule was born: put in your 10, hours of practice, and become an expert in a given field. Pretty easy, right? First of all, Ericsson says, the number 10, is totally arbitrary. And even at 20, they were very good at playing the violin, and probably headed to the top of their field, but they were not yet experts.

In the book Outliers , author Malcolm Gladwell says that it takes roughly ten thousand hours of practice to achieve mastery in a field. How does Gladwell arrive at this conclusion? And, if the conclusion is true, how can we leverage this idea to achieve greatness in our professions? Gladwell studied the lives of extremely successful people to find out how they achieved success. In the early s, a team of psychologists in Berlin, Germany studied violin students. Specifically, they studied their practice habits in childhood, adolescence, and adulthood. All of the violinists had begun playing at roughly five years of age with similar practice times. However, at age eight, practice times began to diverge. By age twenty, the elite performers averaged more than 10, hours of practice each, while the less able performers had only 4, hours of practice. But the data showed otherwise.

The Great Practice Myth: Debunking the 10,000 Hour Rule

Forty years ago, in a paper in American Scientist , Herbert Simon and William Chase drew one of the most famous conclusions in the study of expertise:.

There are no instant experts in chess—certainly no instant masters or grandmasters. There appears not to be on record any case including Bobby Fischer where a person reached grandmaster level with less than about a decade's intense preoccupation with the game. We would estimate, very roughly, that a master has spent perhaps 10, to 50, hours staring at chess positions…. The sole exceptions: Shostakovich and Paganini, who took nine years, and Erik Satie, who took eight. Nobody walks into an operating room, straight out of a surgical rotation, and does world-class neurosurgery.

And second—and more crucially for the theme of Outliers —the amount of practice necessary for exceptional performance is so extensive that people who end up on top need help. They invariably have access to lucky breaks or privileges or conditions that make all those years of practice possible. As examples, I focussed on the countless hours the Beatles spent playing strip clubs in Hamburg and the privileged, early access Bill Gates and Bill Joy got to computers in the nineteen-seventies.

It never is. Recently, there has been some confusion about this argument. Some of the critiques are just bewildering. Here, for example, is a passage from an article in Time a few months ago, which makes me think that there is another Malcolm Gladwell out there, with far more eccentric views than mine, who put on a Halloween wig and somehow conned his way into the Time Life Building:.

With enough practice, he claimed in his book Outliers , anyone could achieve a level of proficiency that would rival that of a professional. It was just a matter of putting in the time. For example, both he and I discuss the same study by the psychologist K. I was interested in the general finding, which was that the best violinists, on average and over time, practiced much more than the good ones. In other words, within a group of talented people, what separated the best from the rest was how long and how intently they worked.

Epstein points out, however, that there is a fair amount of variation behind that number—suggesting that some violinists may use their practice time so efficiently that they reach a high degree of excellence more quickly. There are seventy-three great composers who took at least ten years to flourish. But there is much to be learned as well from Shostakovich, Paganini, and Satie. Epstein makes two other arguments that are worth mentioning. The first is about chess.

He cites a study by Guillermo Campitelli and Fernand Gobet of a hundred and four competitive chess players. This is variation on an extreme scale. Epstein is talking about chess masters —the lowest of the four categories of recognized chess experts. Grandmasters—the highest level—are a different story. Robert Howard, of the University of New South Wales, recently published a paper in which he surveyed a group of eight grandmasters and found that the group hit their highest ranking after fourteen thousand hours of practice.

Even among prodigies who reached grandmaster level before the age of sixteen, we see the same pattern. Almost all of that group reached grandmaster level at fourteen or fifteen, and most started playing when they were four or five. I have nothing against either Australia or Australian basketball. I think that it is also a mistake to assume that the ten-thousand-hour idea applies to every domain.

For instance, Epstein uses as his main counterexample the high jumper Donald Thomas, who reached world-class level after no more than a few months of the most rudimentary practice. He then quotes academic papers making similar observations about other sports—like one that showed that people could make the Australian winter Olympic team in skeleton after no more than a few hundred practice runs.

Skeleton, in case you are curious, is a sport in which a person pushes a sled as fast as she can along a track, jumps on, and then steers the sled down a hill. Some of the other domains that Epstein says do not fit the ten-thousand-hour model are darts, wrestling, and sprinting. As it happens, I have been a runner and a serious track-and-field fan my entire life, and I have never seen a boy who was slow become fast either. Epstein has written a wonderful book.

But I wonder if, in his zeal to stake out a provocative claim on this one matter, he has built himself a straw man. And if the surgeon who wants to fuse your spinal cord did some newfangled online accelerated residency, you should probably tell him no.

It does not invalidate the ten-thousand-hour principle, however, to point out that in instances where there are not a long list of situations and scenarios and possibilities to master—like jumping really high, running as fast as you can in a straight line, or directing a sharp object at a large, round piece of cork—expertise can be attained a whole lot more quickly.
