I've finally had a chance to read Malcolm Gladwell's book Outliers today. As with his previous books, he tends to border on sensationalism focuses on events which may possibly be rare outcomes but wrapping it in a story. The impact here is that he is a great storyteller, but his stories may not necessarily be correct. I can't substantiate that irrefutably but I don't need to.
For example, one chapter focuses on birthdate year as an influential factor describing a host of folks in the computer industry who have gone on to be hugely successful. But at first depoints out that SOME of these folks may have had a series of lucky breaks (e.g. Bill Gates) that gave them an advantage, most not related to their age but to their connections. Then with some quick wave of the hand, he points back to the birthdate year being the summary of the chapter. Okay, what happened there?
Patterns may exist (same location, same birthdate, etc.) but it is a combination of these factors that contribute to success. For that matter, it doesn't qualify if one particular of these factors is a bigger contributor.
He's still a great storyteller and uncovers unusual tales, but from what he has in his books alone, it's hard to tell if what he describes is really is true, or just makes for interesting entertainment. That aside, he has still achieved business star status which can direct people to think that way.
