本研究主要探討教育機構在領導者-成員理論、團體迷思及決策品質之因果關係，以A教育機構為研究對象。並使用多重個案研究法，於2023年2月10日至2023年3月1日訪談6位受訪者，針對上述問題訪談受訪者的方式進行質化研究分析。根據研究結果，本研究提出以下3個主要命題：一、華人世界團體領導者與成員會有較複雜的情感，因信任感並有追隨的行為。二、團體迷思現像不容易被團體察覺為漸進式的現象。三、成員對於團體處於迷思下的決策品質不一致。

This study investigates the causal relationships among leader-member exchange theory, groupthink, and decision quality in educational institutions, using Institution A as the research subject. A qualitative research analysis was conducted through multiple case studies from February 10, 2023 to March 1, 2023, using interviews with the participants to address the aforementioned issues. Based on the research results, three main propositions were proposed in this study. First, leaders and members in the Chinese world have more complex emotions and behavior of trust and followership. Second, groupthink phenomenon is not easily perceived by the group as a gradual process. Third, members have inconsistent views on the decision quality of the group under groupthink.
