探讨了小组讨论对医疗队决策有效性的影响。由三人组成的医生小组诊断了2个假设的医疗病例。每个案例的一些信息在讨论之前都提供给了所有团队成员（共享信息），而其余的信息则在他们之间分配（非共享信息）。与未共享的信息相比，共享的信息更有可能在讨论过程中汇集，并且更早地汇集。此外，团队领导者始终比其他成员更有可能提出问题并重复共享的信息，并且随着时间的推移，也比其他人更有可能重复未共享的信息。最后，汇集未共享（但不共享）的信息提高了团队诊断的整体准确性，而重复共享和未共享的信息会影响诊断的偏差（但不准确）。
The impact of group discussion on the decision-making effectiveness of medical teams was examined. Three-person teams of physicians diagnosed 2 hypothetical medical cases. Some of the information about each case was given to all team members prior to discussion (shared information), whereas the rest was divided among them (unshared information). Compared with unshared information, shared information was more likely to be pooled during discussion and was pooled earlier In addition, team leaders were consistently more likely than other members to ask questions and to repeat shared information and, over time, also became more likely than others to repeat unshared information. Finally, pooling unshared (but not shared) information improved the overall accuracy of the team diagnoses, whereas repeating both shared and unshared information affected bias (but not accuracy) in the diagnoses.
