Abstract

During group decision-making, a group with an imbalanced minority and majority typically suffers normative bias. This bias creates socio-emotional conflict and decreases group member consent and decision power. Thus, we propose a novel video-chat system, "Divided Presence," which aims to reduce this bias by equalizing the apparent number of majority and minority participants using a pseudo-population increase. Members of a discussion use computer graphics avatars on monitors instead of their actual video appearances during communication. The apparent number of discussion members increases when two avatars are assigned to an arbitrary minority member; the avatars then speak on behalf of him or her. We evaluate the system with a three-person consensus game, where a minority member is assigned two avatars. The results show that our system increases the degree of consent among the majority participants when they finally agree to the minority opinion.
