Chapter 20 Communicating Knowledge in Groups

Groups typically are composed of members with different knowledge, information, and expertise. Group discussion provides the means by which members can communicate their unique knowledge to reach better group decisions, develop a shared system for remembering and retrieving knowledge, and establish their expertise through enacted performance. In this chapter, three streams of research are reviewed that explore knowledge communication in groups: Hidden profiles, transactive memory systems, and a performative view of expertise. Each of these three research streams complements and informs the other. Across these three research streams, 10 major research findings are identified. We offer three research directions that include integrating these research streams, examining knowledge communication in the context of emerging technology (e.g., artificial intelligence), and studying effects of knowledge diversity in conjunction with surface-level diversity (e.g., member race).
