Some interesting articles

The latest Edge has an interesting article. I like
this one arguing against Gardner's theory of Multiple Intelligences in favour of a single useful measure "g", which is presumably IQ. The argument is that the curriculum in schools is pandering to Gardner's labels, which aren't orthogonal. I tend to agree that this is a problem, but I wonder whether a roughly-orthogonal set could be found using proper research and data mining or Principle Component Analysis techniques.
