He has put words on paper that confirm.
He garners attention and speaking fees. He has no incentive to speak the truth or actually help people gain expertise. He is almost a fraud.
I can't believe I paid for his crappy book. I feel like an idiot. His "story" about the Korean airlines and the general conclusions he draws borders on the racist and superfluous.
I think you are taking it too far. I read his book Outliers and enjoyed it. And while he may have used the word expert, the overall message of the book that o got was that practice and experience is more important than talent. And there are very few cases I think where that doesn't hold up. And the "outliers" tend to be those that not only practiced a lot, but also had raw talent and lucked out to be in a position to be able to practice a lot.
