Pre-discussion's note-taking in hidden profile tasks

Research output: Contribution to journalArticlepeer-review


It was discovered over three decades ago that groups tend to discuss common information while failing to discuss unique information in group decision-making processes. This is called group's information pooling phenomenon or hidden profile problem. We report a work-in-progress study here that examines the effectiveness of using pre-discussion notes to address hidden profiles in group decision-making. Our data shows a moderate positive correlation between the appearance of a piece of information in participants’ notes and its appearance in the subsequent discussion, suggesting note-taking prior to the group discussion as an effective approach. Our data also indicates that hidden profiles can affect the group performance through aspects other than information sharing.
