Identity fusion is capable of predicting pro-group behaviors. We examine how strongly fused individuals react when they learn the motivations driving other strongly fused individuals’ pro-group behaviors. Three studies were conducted in two countries (Spain and USA). Results showed an attenuation effect in their willingness to fight and die for in-group members when strongly fused individuals learned that other participants displaying their same level of visceral commitment to the group would self-sacrifice for morally relevant reasons, compared to pragmatic reasons. The final study suggests that the attenuation in willingness to fight and die observed in those strongly fused can be interpreted as a sign of confidence to delay their self-sacrifice rather than a need to be unique.
