Innovation Versus Conservation?

While reading a book on innovation by Steven Johnson, several questions occured to Alan Jacobs:

Under what circumstances does a given society need strategies of conservation and preservation more than it needs innovation? … Do the habits of mind (personal and social) that promote innovation consort harmoniously with those that promote conservation and preservation? Can a person, or a society, reconcile these two impulses, or will one dominate at the expense of the other?
