The goal of the current research was to examine how discrete positive intergroup emotional phenomena affect conflict-related attitudes in different contexts of intractable conflict. We hypothesized that empathy, but not hope would be negatively associated with aggressive attitudes during escalation, while hope, but not empathy would be associated with conciliatory attitudes during de-escalation. In study 1, we examined our hypotheses within a correlational design in an emotion-inducing context, while in study 2 a two-wave survey was conducted during real-life events within the context of the Israeli–Palestinian conflict; a peace summit as well as a war. Both studies supported our hypotheses, thus indicating the unique, yet complimentary, contribution of each of the two emotional phenomena to the advancement of peace.
