Citation to materials outside of the traditional legal canon may be for some a source of alarm, but it may as well be a way in which the empirical propositions that are necessarily a part of all judicial lawmaking and much judicial law application can be subject to argument and challenge, rather than simply being clothed in the disguise of common knowledge or what judges believe, not always correctly, and not necessarily unrelated to their own backgrounds, to be the common wisdom of humanity.
