Well I read The Wisdom of Crowds so long ago, I’m not sure what to say:
I do remember enjoying this book a lot.
The idea that depending on how a group is structured and how “voting” takes place a crowd/group can be smart (markets) or stupid (committees). It explored different dynamics present in groups and how those dynamics helped or hindered the desired results.
These sum up the book better.. The books Q & A page, and the Wikipedia page.
