Frameworks and Graphs

Many frameworks consist of boxes with arrows drawn between them. When people introduce a framework, they usually start explaining what each arrow means, e.g. how A -> B represents the specific ways in which A influences B, going down a list of possible interactions.

There isĀ  a different way of looking at the information which the framework provides, which is not what’s in the arrows which are drawn, but rather in the fact that some arrows are missing. Every missing arrow is an assumption that the two factors concerned do not affect each other directly, and these are the assumptions which simplify and accelerate understanding.

Frameworks where every possible arrow has been drawn are uninformative in this regard, and can be replaced by a simple list.
