Their goals in the conflict are shaped by those same interests and values. Clarity of interests can be achieved internally, by each conflict party on its own. There is much to be said, however, for clarifying interests cooperatively with the other side. Being clear about one's own interests in a conflict is usually helped by having your opponents clarify theirs as well. It is important to be clear about what it is you want your opponents to do that would bring about your preferred future.
Values are more difficult than interests to clarify.
It seems that what a conflict party wants is less difficult to know than why they want it. Our values underlay our interests and are thus less visible. We have to hunt harder for them. Yet values are at the core of most conflict. This is a short description of a values clarification exercise which was used in an environmental conflict in Colorado.
