A
controversy currently raging in the Wikipedia community prompted me to think about the fascinating puzzle presented by "open" systems like Science and Democracy.
All such systems are based on a few rules (e.g. science begins with the idea that no fact should be held true in the face of contradicting evidence) and this eventually give rise to a guardian class whose job is to enforce the rules.
If the guardian class is too weak, anarchy is a likely result. If the guardian class is too strong, the system ceases to be "open" -- heresy is the life of a religion.
So how do you get the guardian class tuned just right?
