Identity fusion is a strong feeling of connectedness that is capable of predicting willingness to self-sacrifice. The current research explores whether considering the extremity of the situation improves the ability of identity fusion to predict willingness to engage in life self-sacrifice. Participants first reported their level of identity fusion with a value (Study 1) or with their country (Study 2). Then, participants were randomly assigned to engage in an extreme versus non-extreme situation of sacrifice for the value (Study 1) or for their country (Study 2). These two variables (identity fusion and situation extremity) were used to predict willingness to self-sacrifice. Situation extremity moderated the effects of fusion on willingness to self-sacrifice, with greater consistency between fusion and sacrifice obtained for extreme versus non-extreme situations. In conclusion, taking into consideration the extremity of the situation can be useful to predict the association between identity fusion and willingness to self-sacrifice.

通过考虑情况的极端提高身份融合导致牺牲的预测有效性

身份融合是一种强烈的联系感，能够预测自我牺牲的意愿。目前的研究探讨了考虑极端情况是否可以提高身份融合预测从事生命自我牺牲的意愿的能力。参与者首先报告了他们与价值观（研究 1）或他们的国家（研究 2）的身份融合程度。然后，参与者被随机分配参与极端与非极端情况，为价值（研究 1）或为他们的国家（研究 2）做出牺牲。这两个变量（身份融合和情境极端）被用来预测自我牺牲的意愿。情境极端调节融合对自我牺牲意愿的影响，在极端与非极端情况下获得的融合和牺牲之间具有更大的一致性。总之，考虑到情况的极端可能有助于预测身份融合与自我牺牲意愿之间的关联。
