The goal of this research was to examine whether a denial of a prolonged occupation by the occupying society constitutes a meaningful sociopsychological barrier to resolving the conflict peacefully. We hypothesized that this perception will be associated with objections both to conflict resolution processes and to specific compromises intended to end the occupation. Furthermore, we hypothesized that the association between denial of the occupation and compromises will be partially mediated by denial of its costs, low levels of moral emotions, and closure to new information about the conflict. Taking the prolonged Israeli occupation as our case study, we used three nationwide representative polls of Jewish Israelis to test our hypotheses. The studies supported our hypotheses, pointing to the distinct role that the perception of prolonged occupation by the occupying society plays in peacefully ending this situation, and the psychological mechanisms underlying occupation denial as a barrier to conflict resolution.
