Differential Information Access

Research indicates that group discussions often focus on information that is commonly known among members, neglecting the valuable insights that arise from diverse perspectives. The concept of Hidden Profiles highlights how groups like teams of physicians tend to discuss shared information more frequently, while unshared information—potentially crucial for decision-making—remains underutilized. This imbalance can hinder the effectiveness of team discussions. Strategies to surface and leverage unshared insights are vital for improving decision outcomes.
