Not sure what you mean by "divisive." I think "externalize their imaginations into real what if this happens scenarios" is pretty much what I was saying, although maybe I am tying it a bit more to why it is useful: i.e. practicing for real things that could happen, so they will be able to handle those situations better than if they had never considered such possibilities previously.
