In this paper we focus on how to use CBR for making collective decisions in groups of agents. Moreover, we show that using CBR allows us to dispense with standard but unrealistic assumptions taken in these kind of tasks. Typically, social choice studies voting methods but assumes complete knowledge over all possible alternatives. We present a more general scenario called open-ended deliberative agreement with rational ignorance (ODARI), and show how can CBR be used to deal with rational

Rational ignorance makes sense in this scenario, since it would be unreasonable for the agents to know all the alternatives. Unknown alternatives, as well as a strategy to increase chances of reaching an agreement, are problems addressed using case-based methods. 3 The word satisfice was proposed by Herbert Simon in 1956 as an alternative desideratum for AI tasks, in contrast with the more classical word maximize; Simon championed the notion of bounded rationality as a more realistic approach to rationality that takes into account different kinds of cognitive limitations. 4 We will consider group decisions as a form of group agreement. In our approach, negotiation, mediation, social choice, etc. are different kinds of processes whose aim is to reach agreements between 2 or more agents. In what follows, we will speak of group decision or agreement interchangeably.
