ABSTRACT This study examined the effect of narrative messages of a massive fire crisis on optimistic bias by experimentally comparing the effect of narrative describing a personal story on the crisis incident and that of non-narrative message (Study 1). Researchers further sought the interaction between controllability and the narrative message and the mediated moderation model of risk perception. In Study 2, the effect of narrative message describing a group story on the crisis incident on optimistic bias was further tested in terms of South Korea’s collectivistic culture. Collectivism, along with controllability, was used as a moderator, and mediated moderation models of risk perception were tested. The present research offers several major findings: (1) a narrative message describing a personal story decreased optimistic bias, (2) among people who read a narrative describing a personal story, those with high controllability had a lower level of optimistic bias than those with low controllability, (3) among people who read the narrative of a group story, those with high collectivism had a lower level of optimistic bias than those with low collectivism, and (4) the interaction between message types and collectivism affected risk perception and this risk perception increased optimistic bias. Theoretical implications of these findings are discussed.

叙事信息对韩国乐观偏见的影响：关注大规模火灾危机中的可控性、集体主义和风险感知

摘要 本研究通过实验比较描述个人故事的叙事对危机事件的影响和非叙事信息的影响（研究 1），检验了大规模火灾危机的叙事信息对乐观偏见的影响。研究人员进一步寻求可控性和叙事信息之间的相互作用以及风险感知的中介调节模型。在研究 2 中，根据韩国的集体主义文化进一步检验了描述集体故事的叙事信息对乐观偏见危机事件的影响。集体主义与可控性一起被用作调节器，并测试了风险感知的中介调节模型。目前的研究提供了几个主要发现：（1）描述个人故事的叙事信息减少了乐观偏见，（2）在阅读描述个人故事的叙事的人中，高可控性的人比低可控性的人具有较低的乐观偏见，（3）在阅读集体故事的叙事的人中，高集体主义的人有与低集体主义的人相比，乐观偏见水平较低，并且（4）消息类型和集体主义之间的相互作用影响了风险感知，而这种风险感知增加了乐观偏见。讨论了这些发现的理论意义。(4) 消息类型和集体主义之间的相互作用影响了风险感知，这种风险感知增加了乐观偏差。讨论了这些发现的理论意义。(4) 消息类型和集体主义之间的相互作用影响了风险感知，这种风险感知增加了乐观偏差。讨论了这些发现的理论意义。
