In our everyday moral deliberations, we attend to two central types of considerations – outcomes and moral rules. How these considerations interrelate is central to the long-standing debate between deontologists and utilitarians. Is the weight we attach to moral rules reducible to their conduciveness to good outcomes (as many utilitarians claim)? Or do we take moral rules to be absolute constraints on action that normatively trump outcomes (as many deontologists claim)? Arguments over these issues characteristically appeal to commonsense intuitions about various cases. As a result, an important portion of the debate involves empirically tractable questions — questions that can be investigated by probing for people’s judgments in cases in which the two types of considerations come into conflict with one another.

It is commonly thought that moral rules and principles, such as ‘Keep your promises,’ ‘Respect autonomy,’ and ‘Distribute goods according to need ,’ should play an essential role in our moral deliberation. Particularists have challenged this view by arguing that principled guidance leads us to engage in worse decision making because principled guidance is too rigid and it leads individuals to neglect or distort relevant details. However, when we examine empirical literature on the use of rules and principles in other domains, we find that people can learn to use rules discriminately and that rule-based models tend to outperform even expert judgment. I argue that this evidence poses a problem for the moral particularist. If the particularist claims that we should not rely on decision-making rules when making practical decisions and it turns out that these rules help us make better decisions, then the particularists’ prescriptive account is deficient. However, if the particularist claims that we should rely on practical decision-making rules but not on moral rules, she needs to explain how practical rules are different from moral rules and why we should rely on the former but not the latter
