The document summarizes research on the phenomenon of "reactive devaluation" in negotiation and conflict resolution. Initial studies found that people were more positive about a nuclear disarmament proposal when it was attributed to their own leader rather than the adversary's leader. Further experiments at Stanford University during a campus debate over divestment from South Africa found that students rated compromise proposals as less significant or attractive when those proposals were described as being offered by the university rather than just presented as options. The research provides evidence that the source of a proposal can influence how positively or negatively it is evaluated.
