Abstract

An algorithm (termed CONFIDE) is proposed that may capture many of the benefits of group decision making without the necessity of face-to-face interaction. The algorithm allows individual decision makers to differentially weight the contributions from members according to the confidence with which each member holds to their opinions. The CONFIDE algorithm is compared to both face-to-face group decisions and simple averaging of group members opinions on the Lost-at-Sea ranking task. Results indicate that, in terms of decision quality, the CONFIDE algorithm produces solutions equal to that of the face-to-face group decision method and significantly better than the solution achieved by simple averaging of group members responses.
