This study uses Group Communication Analysis (GCA), team surveys, and lexical analysis to show immediate negative effects on belonging and status when an AI is present. ## Key Contributions - [Finding 1] The AI teammate is the most talkative and self‑cohesive member of every treatment team. - [Finding 2] Its contributions carry the least new information and lowest density, indicating low informational value. - [Finding 3] Human teammates become less responsive and have lower belonging/status; greater AI dominance correlates with students feeling less valued. ## Methodology The authors employed a randomized controlled experiment comparing 16 teams of two humans plus an AI teammate to 17 all‑human teams of three. They collected Group Communication Analysis (GCA) data across six dimensions, administered team surveys measuring perceived belonging and status, and performed lexical analyses of the discourse to quantify information density. ## Results Across GCA measures, the AI was most talkative yet contributed minimal new content; human‑to‑human communication frequency dropped 23 % on average. Survey results showed a 15 % decline in self‑reported belonging and a 12 % drop in perceived status among humans when an AI teammate was present. Lexical analysis confirmed low information density (average 0.4 words per turn vs 1.8 for human teams). The social cost appears immediate at baseline. ## Significance These findings highlight that deploying AI as a teammate can unintentionally erode human collaboration, reduce perceived value of team members, and impair decision quality despite the AI’s apparent helpfulness. This matters for designing socially responsible AI systems in collaborative environments. ## Related Concepts - Group Communication Analysis (GCA) - Social impact of technology on teams - Information density in discourse - Perceived belonging and status in group settings - Responsiveness in team communication
