The paper introduces a feedback-oriented approach to group decision support. This approach is based on the notion that in many cooperative group settings, an agreement is not reached by making concessions but by gradually changing the preferences of group members. Two possible ways of such preference changes are identified and formal methods for them are developed. The approach is illustrated by an example using the reference point approach as evaluation technique.
