Information exchange and use in GSS and verbal group decision making: effects of minority influence

The purpose of this study was to investigate the effects of GSS use on the exchange and use of information in group decision making under two conditions: when there was and was not a majority/minority split of opinion in the group. When there was a distinct majority/minority groups using a GSS exchanged more information, made better decisions, and took no more time than when they did not use a GSS. In the uniform treatment where there was no majority/minority, groups using a GSS exchanged more information but made worse decisions, and took more time than when they did not use a GSS.
