Outliers, 10,000 hrs of Practice
Friday, November 21, 2008 at 7:26AM I just finished reading Malcolm Gladwell’s Outliers book.
Amazon Best of the Month, November 2008: Now that he's gotten us talking about the viral life of ideas and the power of gut reactions, Malcolm Gladwell poses a more provocative question in Outliers: why do some people succeed, living remarkably productive and impactful lives, while so many more never reach their potential? Challenging our cherished belief of the "self-made man," he makes the democratic assertion that superstars don't arise out of nowhere, propelled by genius and talent: "they are invariably the beneficiaries of hidden advantages and extraordinary opportunities and cultural legacies that allow them to learn and work hard and make sense of the world in ways others cannot." Examining the lives of outliers from Mozart to Bill Gates, he builds a convincing case for how successful people rise on a tide of advantages, "some deserved, some not, some earned, some just plain lucky."
Outliers can be enjoyed for its bits of trivia, like why most pro hockey players were born in January, how many hours of practice it takes to master a skill, why the descendents of Jewish immigrant garment workers became the most powerful lawyers in New York, how a pilots' culture impacts their crash record, how a centuries-old culture of rice farming helps Asian kids master math. But there's more to it than that. Throughout all of these examples--and in more that delve into the social benefits of lighter skin color, and the reasons for school achievement gaps--Gladwell invites conversations about the complex ways privilege manifests in our culture. He leaves us pondering the gifts of our own history, and how the world could benefit if more of our kids were granted the opportunities to fulfill their remarkable potential. --Mari Malcolm
One of the interesting points is 10,000 hrs of practice are required to achieve a level of expertise. An excerpt published in the Guardian is available.
This idea - that excellence at a complex task requires a critical, minimum level of practice - surfaces again and again in studies of expertise. In fact, researchers have settled on what they believe is a magic number for true expertise: 10,000 hours.
"In study after study, of composers, basketball players, fiction writers, ice-skaters, concert pianists, chess players, master criminals," writes the neurologist Daniel Levitin, "this number comes up again and again. Ten thousand hours is equivalent to roughly three hours a day, or 20 hours a week, of practice over 10 years... No one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery."
For an exercise I tried to figure out what I had practiced for 10,000 hrs. And, what I came up with is being a technology evangelist.
A technical or technology evangelist is a person who attempts to build a critical mass of support for a given technology in order to establish it as a technical standard in a market that is subject to network effects.[citation needed] Professional technology evangelists are often employed by firms which seek to establish their proprietary technologies as de facto standards or to participate in setting non-proprietary open standards. Non-professional technology evangelists may act out of altruism or self-interest (e.g., to gain the benefits of early adoption or the network effect).
Technical evangelists may act, officially or unofficially, on behalf of a company or organisation, or on a personal basis, for instance open source evangelism. An evangelist promotes the use of a particular product or technology through talks, articles, blogging, user demonstrations, recorded demonstrations, or the creation of sample projects. The word evangelism is taken from the context of religious evangelism because of the similar recruitment of converts and the spreading of the product information through the ideological or committed.
Being independent of an organization has allowed me to have more fun blogging on the Green Data Center topic, and working with whoever I want. Working at companies like Apple and Microsoft I learned a lot, but being on my own is turning out to be like graduating from college, taking the path of altruism.
Blogging is part of my practice; researching and writing about technology and methods to create greener data centers. I have a long way to go to achieve 10,000 hrs on green data centers, but I am sure time will go by quickly.

This is consistent with their performance on math/science subjects. Seligman also notes possible explanations of this including:
"Severely compressed, his explanation goes about like this: Some sixty thousand years ago, when the lee Age descended on the Northern Hemisphere, the Mongoloid populations faced uniquely hostile "selection pressure" for greater intelligence. Northeast Asia during the Ice Age was the coldest part of the world inhabited by man. Survival required major advances in hunting skills. Lynn's 1987 paper refers to "the ability to isolate slight variations in visual stimulation from a relatively featureless landscape, such as the movement of a white Arctic hare against a background of snow and ice; to recall visual landmarks on long hunting expeditions away from home and to develop a good spatial map of an extensive terrain." These, Lynn believes, were the pressures that ultimately produced the world's best visuospatial abilities."
Also, Gladwell's explanation for Jewish legal success on working in the garment industry in NYC isn't convincing. Seligman notes jewish performance on the verbal component of psychometric tests is above average. The Cochran/Harpending paper on Ashkenazi Jewish intelligence suggests this is partly genetic. See Charles Murray's commentary on the paper:
"To get a sense of the density of accomplishment these numbers represent, I will focus on 1870 onward, after legal emancipation had been achieved throughout Central and Western Europe. How does the actual number of significant figures compare to what would be expected given the Jewish proportion of the European and North American population? From 1870 to 1950, Jewish representation in literature was four times the number one would expect. In music, five times. In the visual arts, five times. In biology, eight times. In chemistry, six times. In physics, nine times. In mathematics, twelve times. In philosophy, fourteen times.
Disproportionate Jewish accomplishment in the arts and sciences continues to this day. My inventories end with 1950, but many other measures are available, of which the best known is the Nobel Prize. In the first half of the 20th century, despite pervasive and continuing social discrimination against Jews throughout the Western world, despite the retraction of legal rights, and despite the Holocaust, Jews won 14 percent of Nobel Prizes in literature, chemistry, physics, and medicine/physiology. In the second half of the 20th century, when Nobel Prizes began to be awarded to people from all over the world, that figure rose to 29 percent. So far, in the 21st century, it has been 32 percent. Jews constitute about two-tenths of one percent of the world’s population.
What accounts for this remarkable record? A full answer must call on many characteristics of Jewish culture, but intelligence has to be at the center of the answer. Jews have been found to have an unusually high mean intelligence as measured by IQ tests since the first Jewish samples were tested. (The widely repeated story that Jewish immigrants to this country in the early 20th century tested low on IQ is a canard.) Exactly how high has been difficult to pin down, because Jewish sub-samples in the available surveys are seldom perfectly representative. But it is currently accepted that the mean is somewhere in the range of 107 to 115, with 110 being a plausible compromise.
The IQ mean for the American population is “normed” to be 100, with a standard deviation of 15. If the Jewish mean is 110, then the mathematics of the normal distribution says that the average Jew is at the 75th percentile. Underlying that mean in overall IQ is a consistent pattern on IQ subtests: Jews are only about average on the subtests measuring visuo-spatial skills, but extremely high on subtests that measure verbal and reasoning skills."
"Assessing the events of the 1st century C.E. thus poses a chicken-and-egg problem. By way of an analogy, consider written Chinese with its thousands of unique characters. On cognitive tests, today’s Chinese do especially well on visuo-spatial skills. It is possible, I suppose, that their high visuo-spatial skills have been fostered by having to learn written Chinese; but I find it much more plausible that only people who already possessed high visuo-spatial skills would ever devise such a ferociously difficult written language. Similarly, I suppose it is possible that the Jews’ high verbal skills were fostered, through secondary and tertiary effects, by the requirement that they be able to read and understand complicated texts after the 1st century C.E.; but I find it much more plausible that only people who already possessed high verbal skills would dream of installing such a demanding requirement."
