Is Intelligent Design falsifiable? Matheson says "no."

Steve Matheson has posted a discussion on the question of whether Intelligent Design (ID) is falsifiable. Most people who have thought about it say that a theory is not a valid scientific theory unless it could be somehow disproved. Matheson makes a good case that ID is not falsifiable. This, as he says, does not prove that ID is not true, but it means that it cannot be taken as a valid scientific theory.
