The effect of group composition on risk taking was investigated by having various 3-man groups discuss caution-oriented items. Results indicated: (1) only one of nine group types exhibited a significant shift to caution; (2) except for the homogeneous groups, in which there were no shifts, significant shifts in individual decisions did occur, at least for some of the members, in all of the group composition types; (3) compromising effects, in which group members shifted toward each other, were evident; (4) low risk takers changed their decisions least often, highs next, and moderates most often. Findings were related to previous research in the area. (Author)
