"Outliers" are not politicians who lie even more than other politicians. It is a term used by statisticians to describe some data that are far away from the average-- data on seven-foot women or freezing temperatures in Los Angeles, for example.

"Outliers" is also the title of a very insightful and very readable new book by best-selling author Malcolm Gladwell. The book's subtitle is "The Story of Success." It is a study of the factors behind people who have had spectacular achievements in fields ranging from hockey to computers.

One of the first groups of outliers studied are top-level Canadian hockey players, a wholly disproportionate number of whom were born in the first three months of the year. Moreover, the same pattern was found among top Czech hockey players.

The key factor turned out to be a fixed date-- January 1st in both countries-- for selecting young boys to be placed on special hockey teams that were the elite of their age groups.

Players born in January were the most over-represented among the top hockey players in both countries. As young boys, they would have just missed the selection cut-off for that year and would have had another year to grow before the next selection date.

Obviously a boy born the day after the selection date would be virtually a year older when the next selection date came around, compared to a boy born the day before the selection date, even though they were both officially the "same" age, competing for places on the same elite hockey teams.

That kind of difference in age-- at a very young age-- was a big advantage, in terms of size and physical maturity, among boys in a very physical sport. Being tracked into elite hockey teams, early on, allowed that initial advantage to be parlayed into an ever larger advantage of experience and training with elite teams over the years.

Many other "outliers" in achievement in many other fields likewise came from special backgrounds or special circumstances. These people have been in areas ranging from computers to corporations to residents of one Pennsylvania town with unusually low rates of heart disease, despite having residents whose diets are laden with fat and sugar, who do little exercise and who tend to be obese.

The theme running through this book is that spectacular individual achievements-- outliers-- are not simply a matter of personal merit but come out of a background of special circumstances that enable outstanding individual ability to lead to performances far beyond the norm.
