The Effects of Anonymity on GDSS Group Process with an Idea-Generating Task

This study examines the influence of anonymity on group process in groups using a group decision support system (GDSS) with an idea-generating task. Group members whose contributions were anonymous generated more comments, were more critical and probing, and were more likely to embellish ideas proposed by others than were those whose contributions were identified by name. Implications for group support research are discussed.
