Group Composition,Creative Synergy,and Group Performance

Organizations use groups to improve performance on tasks that require problem solving. Is this belief in the problem solving benefits of groups misplaced given the process-losses often experienced by brainstorming groups? This study of 94 intact autonomous work groups performing multi-part tasks revealed that group creative performance increased multiplicatively (exponentially) with the number of highly creative group members composing the group. However, this occurred only when Team Creativity-Relevant Processes (TCRP) within the group were relatively high. When TCRP were relatively low, group creative performance decreased multiplicatively with the number of highly creative group members within it. When TCRP were about average for the sample, group performance increased only linearly with the number of highly creative members within a group.     

MOORE, THE SKEPTIC, AND THE PHILOSOPHICAL CONTEXT*

Abstract:  I argue that Moore's arguments have anti-skeptical force even though they beg the question against skepticism because they target the skeptic rather than skepticism directly. Moore offers two arguments which are usually conflated by his interpreters, namely, his proof of an external world and a reductio argument. I explain why the anti-skeptical force of the latter has to be derived from that of the former. I consider an objection to Moore that is based on distinguishing between the everyday and the philosophical contexts. I argue that the objection fails even on the most plausible understanding of the distinction.
