Individual-level analyses revealed that members of GDSS groups that did not have a prediscussion consensus tended to experience stronger preference shifts toward the group's consensus decision, especially when there was a lack of prediscussions consensus.
Abstract
This study compared a group decision support system (GDSS) with face-to-face (FTF) group discussion on characteristics of information exchange and decision quality. Participants given conflicting information tended to share more of their unique data and engaged in more critical argumentation when using the GDSS than when meeting FTF. Conversely, when information was consistent among members, there were no such differences between FTF and GDSS groups. The GDSS groups significantly outperformed the FTF groups in agreeing on the superior hidden profile candidate, especially when there was a lack of prediscussion consensus. Individual-level analyses revealed that members of GDSS groups that did not have a prediscussion consensus tended to experience stronger preference shifts toward the group's consensus decision.

A conceptual overview of GDSS based on an information-exchange perspective of decision making is presented, and a multi-dimensional taxonomy of systems is proposed as an organizing framework for research in the area.

Findings suggest that social equalization was higher in computer-mediated groups in that group members participated more equally in discussions and exhibited more uninhibited behavior—using strong and inflammatory expressions in interpersonal interactions.

This study concluded that the elimination of production blocking in the computer-based groups (a problem common in groups that communicate verbally where only one member of the group can speak at a time) accounts for a significant portion of the enhanced productivity for theComputer- based groups.
