So nothing that Gladwell writes has justification? Seems like you have a deep hatred of his writing and are unable to critique his ideas objectively.
I read the article; I have read the 10 years/10,000 hours peice and it's detractors numerous times. I don't use that one argument to tear down a man's work though. People fixate on one part of one chapter.
His study of the Gore-Tex working practices and racism in the Caribbean I thought were particularly excellent.
