A randomized controlled study compared 16 AI-human teams (two students plus an AI teammate) against 17 all-human three-person teams on a high-stakes moral-dilemma decision task. Using Group Communication Analysis, surveys, and lexical analysis, researchers found the AI was the most talkative and self-cohesive member in every AI-human team, yet contributed the least new information and lowest density. The presence of an AI teammate reduced human-to-human responsivity and social impact, and was associated with lower reported belonging and status among human members — effects that appeared immediately rather than developing over time.
