It's an interesting book but a little deceptive, IMO. Some of his stories about intuition are about average blokes with a hunch, but many of them are about experts who have deep knowledge about the subject they are puzzled by/interested in.
So it's not clear what kind of intuition he is talking about all the time - hunches, informed guesses, or experts who just know something is going on without putting a finger on it.
His intro story on the statuary, for example, is a neat story, but I don't really see it as an issue of intuition.
It should be read alongside James Surowiecki's "Wisdom of Crowds" for a different take on information processing.
