While direct control of internal factors such as psychological safety is difficult in improving organizational performance, structural factors such as organizational structure and communication network are relatively easy to control by organization policy or personal effort. Therefore, in an exploratory manner, this study aims to analyze the influence of organizational structure on members' psychological and decision-making processes through a multi-agent simulation using Large Language Models (LLMs). For the analysis, we combined the Semantic Similarity Rating method with "LLM as a judge" to quantify indicators such as critical thinking and groupthink from conversation logs. The results suggest an increase in the volume of inter-community conversation activates critical thinking and contributes to the stable improvement of progress. On the other hand, isolated communities, far from enhancing uniqueness, exhibited a "paradox of insularity" where excessive conformity caused thinking to become homogenized and clichéd. This suggests the importance of incorporating heterogeneity through weak ties.
