Conflict-resolution interventions based on the paradoxical thinking principles, that is, expressing amplified, exaggerated, or even absurd ideas that are congruent with the held conflict-supporting societal beliefs, have been shown to be an effective avenue of intervention, especially among individuals who are adamant in their views. However, the question as to why these interventions have been effective has remained unanswered. In the present research, we have examined possible underlying psychological mechanisms, focusing on identity threat, surprise, and general disagreement. In a small-scale lab study and a large-scale longitudinal study, we compared paradoxical thinking interventions with traditional interventions based on providing inconsistent information. The paradoxical thinking interventions led rightists to show more unfreezing of held conflict-supporting beliefs and openness to alternative information, whereas the inconsistency-based interventions tended to be more effective with the centrist participants. Both studies provide evidence that the effects were driven by identity threat, surprise, and lower levels of disagreement.
