Great Post on the Toleration of Error and American History

This blog post from Freakonomics seems fairly closely related to my post yesterday on religion and the liberal state. The ideas are quite similar to my thoughts on procedural norms vs. prescriptive norms, though in a rather different context that doesn't directly have to do with religion. It also reminds my of Erasmus's In Praise of Folly, though it has been long enough since I read it that my hazy recollection my be misinterpreting the relation.

I have nothing in particular to add to the Freakonomics post but thought I'd share for anyone interested in the subject.
