Counterinsurgency For U.S. Government Policymakers

.....As I mentioned in my earlier post, I tend to use fuzzy sets rather than crisp sets, so I really have no problems with the idea that a singular observed action / event can be part of more than one "term"....

So you aren't really talking about "sets" you're talking about confidence intervals. In general these "terms" fall within this area but not always.
