Today I am thinking about the wisdom of crowds versus that of experts. The wisdom of crowds is typical known as statistical groups. The theory holds that large groups of people (the larger the better) are statistically more accurate than experts. This is ONLY true when any one person within the group is likely to be more than 50% right.
This principle underlies the philosophy of our democratic system. So my question is what role do experts and/or librarian play in this type of information system? Do we provide a check/balance to the crowd?
I guess from my point-of-view, I believe that people are good. That they want to add to the information flow in an honest manner. That they don’t change wiki pages they know nothing about.
