Abstract
Much recent research indicates that discussion predictably affects responses to choice-dilemma items. In the present experiment, 12 choice-dilemma items were discussed to consensus by 40 female groups of varying size (2, 3, 5, or 7 members). Group size did not significantly affect shift scores. Over all groups, the mean of initial risk taking on an item was an excellent predictor of the mean amount of shift that item elicited ( r = –.89), a finding consistent with certain models of group decision making as well as with the idea that discussion arguments enhance dominant values. Further analyses of the present and past research indicated that the group decision making models could not account for the observed shifts.
