'Wisdom of Crowds' and Central Limit Theorem - 05 January, 2007

			zzbbyy says
			"But it's limited by the fact that Surowiecki has essentially one picture of how collective cognition could work, namely averaging a lot of guesses which are randomly and independently distributed around the true answer --- in other words, the central limit theorem" from a comment by apparently an academic. What do you think? I don't remember much from my math education - but it seems credible to me. If this is right than the really hot book is somehow trivial - i.e. it's just a list of examples for some math theorem and it's thesis is very limited as it is only applicable exactly where the theorem assumptions are met.

			Hey thanks for pointing out the link. I ordered the book "The Wisdom of Crowds: why the many are smarter than the few and how collective wisdom shapes business, economies, societies and nations". It will make for a good reading.
