All stories have both Action and Decision. Typically, one defines a Decision story as having more Deliberation or more intense Deliberation than Action. This view is overly influenced by how the story is told, rather than what it represents. More accurately, either Actions force the need for Decisions or Decisions force the need for Actions in order to advance the plot. Over the course of the story as a whole (independent of the nature of the Main Character) if Decisions precipitate the progression of the plot, it is a Decision story.
