  We propose Exanna, a framework to realize agents that incorporate values in
decision making. An Exannaagent considers the values of itself and others when
providing rationales for its actions and evaluating the rationales provided by
others. Via multiagent simulation, we demonstrate that considering values in
decision making and producing rationales, especially for norm-deviating
actions, leads to (1) higher conflict resolution, (2) better social experience,
(3) higher privacy, and (4) higher flexibility.
