 Knowledge about the distribution of information and group decision making: When and why does it work?Wendy P. van Ginkel and Daan van Knippenberg Organizational Behavior and Human Decision Processes, 2009, vol. 108, issue 2, 218-229 Abstract: Research has shown that decision-making groups with distributed information perform better when group members know which member is knowledgeable about what. Thus far research has been unable to identify the process responsible for this effect. In the present study, we propose that group members' task representations mediate the effect of knowledge about the distribution of information on decision performance. Building on this proposition, we also propose that reflection about the task moderates the effect of knowledge about distributed information through its effect on task representations. These hypotheses were put to the test in an experimental study of decision-making groups (N=125). As predicted, knowledge of distributed information interacted with reflection to affect decision quality. Findings confirmed the proposed mediating role of task representations and information elaboration.
