 Reciprocity, argue the authors, implies another commitment—to “the economy of moral disagreement.” Citizens must justify their positions by using the least controversial rationale available.  The principle of economy encourages those engaged in deliberation to look for justifying reasons that overlap with rather than contradict beliefs held by others. To be morally justifiable under a conception of deliberative democracy, a truth commission needs to economize on disagreement. An example of economizing in the work of South Africa's TRC is the decision not to grant blanket amnesties and to insist on the indictment of some of the worst perpetrators.
