MoralDM : A Computational Model of Moral Decision-Making

We present a cognitively motivated model of moral decisionmaking, MoralDM, which models psychological findings about utilitarian and deontological modes of reasoning. Current theories of moral decision-making extend beyond pure utilitarian models by including contextual factors that vary culturally. Our model employs both first-principles reasoning and analogical reasoning to implement rules of moral decision-making and compare previously solved cases to novel situations. The different impacts of secular versus sacred values are modeled via qualitative reasoning, using an order of magnitude representation. We evaluate MoralDM on stimuli taken from two psychology experiments.
