If one refers to N as the set of connections among facts whereas S refers to the set of facts, the two categories of information will overlap like A and B does in the diagram below. The overlap is where S and N are the same because it's information that's both fact and connection or it's both absolute and relative or both quantitative and qualitative. If one assumes that the diagram represents the total S and N information that is available for a particular person to input, the overlap can vary greatly. Theoretically, a particular type will operate only within the N or S circle but it can be hard to distinguish which circle one is in when one operates primarily within the overlap. A similar confusion can exist among T and F processes.
