先前的研究发现，决策小组不能有效地汇集未共享的信息。本研究考察了个人专业知识如何通过提高成员对谁拥有什么类型信息的认识，促进集体回忆和决策小组中未共享信息的提及和验证。在集体回忆和决策任务中，分配的专业知识大大增加了提到的非共享信息的比例。两个结果支持了分配的专业知识为非共享信息的回忆提供验证的假设。当分配专业知识时，(a)更多在回忆任务中提到的非共享信息被保留在集体认可的书面协议上，(b)讨论中提到的非共享信息更有可能在小组互动后被成员正确识别。
Previous research has found that decision-making groups do not effectively pool unshared information. This study examined how personal expertise facilitates the mentioning and validation of unshared information in collective recall and decision-making groups by increasing members' awareness of who holds what types of information. Assigned expertise increased substantially the proportion of unshared information mentioned during both collective recall and decision-making tasks. Two results supported the hypothesis that assigned expertise provides validation for the recall of unshared information. When expertise was assigned, (a) more of the unshared information mentioned during the recall task was retained on the collectively endorsed written protocol, and (b) unshared information that was mentioned in discussion was more likely to be correctly recognized by members after group interaction.
