Synthesis: Wiss et al. (2025) describe a mixed-methods study that introduced a generative AI agent — CALIE (Collaborative Agent for Learning and Interprofessional Exploration) — into twelve newly formed interprofessional student teams in a virtual problem-based learning session, intentionally prompted to inject controversial viewpoints and counter groupthink. Across 158 survey respondents from seven health-professions graduate programs, the genAI agent positively influenced group dynamics, stimulated critical thinking and engagement, and limited groupthink's potential. The faculty facilitator's stance toward the AI significantly shaped students' acceptance of it, and students' perceptions of the AI as useful, helpful, and part of the team differed significantly and were positively intercorrelated.

Key Findings

  • genAI agents can counter groupthink. Students reported that the agent's regularly introduced controversial responses stimulated critical thinking, introduced divergent outside viewpoints, and gave teams a launchpad to analyze the AI's output using their own disciplinary knowledge — steering groups away from conformity-driven consensus.
  • Quantitative perceptions. A repeated-measures ANOVA (F(2, 156) = 26.01, p < .001) found students agreed most that AI can be a useful tool (M = 3.49), then that its feedback was helpful (M = 3.21), and least that AI felt part of the team (M = 2.88); all pairwise comparisons differed significantly. The three items were all positively correlated.
  • Facilitator influence matters. Students who said their faculty facilitator influenced how they integrated the AI reported more positive AI perceptions on all three measures — e.g., viewing AI as part of the team (M = 3.08 vs 2.64, F(1,156) = 5.96, p = .02) and finding its Feedback helpful (M = 3.44 vs 2.93, F(1,156) = 10.26, p = .002).
  • Disagreement with the AI aided teamwork. Even when learners rejected or mistrusted the agent's responses, the act of engaging with or refuting them offered a socially permissible way to speak up, stimulating reflection and conversation and counteracting passivity in unfamiliar teams.
  • Mixed bias findings. Perceptions of AI bias were "complex and messy" — some students held personal negative bias toward AI, and it was unclear whether they labeled controversial responses "biased" because they disagreed with the content; bias in interprofessional AI settings is flagged for future research.

Study Design & Method

A mixed-methods study under Yale IRB. 165 graduate health-professions learners (158 opted into the survey) from seven programs (MPH, nursing, AGACNP, DPT, PharmD, DDS, Physician Associate) were divided evenly across twelve small groups, each facilitated by a faculty member. Teams completed a synchronous 180-minute virtual problem-based learning session using the VIPE interprofessional education methodology, during which the CALIE genAI agent was voiced at three points to introduce potentially controversial perspectives. Data came from an online post-activity survey combining quantitative perception items (analyzed with repeated-measures and multivariate ANOVAs) and qualitative open responses.

Implications for AI in Education

For educators and learning designers running team-based problem-based learning, intentionally prompted generative AI agents can serve as productive "devil's advocates" that inject controversy, stimulate critical thinking and engagement, and counteract the conformity pressures that produce groupthink — especially valuable in interprofessional settings where diverse perspectives are the pedagogical goal. The facilitator's role is pivotal: their framing and stance toward the AI substantially shapes whether students accept and benefit from it. The study cautions that AI bias perception is complex and that learner skepticism can coexist with productive engagement.
