Training over talent?

On a related note to the "teams over talent" post, a bunch of articles I've been reading about what I would have called the truly talented basically argue that it is training that matters much more than talent. The collapse of the "aptitude" test concept in favor of a focus on "achievement" buttress that argument as well. Here's a Gladwell article about Kaplan that makes this point - http://www.gladwell.com/2001/2001_12_17_a_kaplan.htm. See also this updated post from Freakonomics on the training over talent concept (http://freakonomics.blogs.nytimes.com/2007/08/20/how-talented-is-this-kid/) and this piece on expertise (http://www.leggmason.com/funds/knowledge/mauboussin/Are_you_an_expert.pdf). My Grad Business classes make similar arguments about experts being good at "intuition" and models being good at analysis.
