Worldview conflicts are not a separate category of conflict. Every conflict has a worldview dimension. And there may be some conflicts where it's not as relevant to the parties and you don't have to deal with it directly, but that doesn't mean that dimension of their interaction isn't there. If something breaks down in the negotiation process, we have to ask ourselves if we just hit a worldview block of some kind? As opposed to an integrity block, where parties are not operating with integrity or miscommunicating or something. You better go back to see if there's some sort of underlying reality problem. So that would be one key lesson that I've learned.
