A Google Books search can help in identifying the frequency of the term's usage prior to DI, such as by singling out 19th Century literature. Seems to have been widely used as a term even in the 1800s and some even refer to it as the "theory of Intelligent Design" rather than using the term as some sort of placeholder. Due to that, I think a terminology section would be in order here. As for how to use the term in the rest of the article, I think we should stick to the normal term as opposed to adding a qualifier as this article is about the DI formulation of the same name. We only need to qualify the distinction where necessary to define the subject. The reader should just be able to recognize that we are using "Intelligent Design" as a term for the DI formulation. tlk. cntrb.
