The role of diagnosis and decision theory in normative reasoning

A theory of diagnosis and qualitative decision theory are able to formalize reasoning `with' norms. They are thus different from deontic logic, that formalizes reasoning `about' norms. In this paper, we compare two theories of diagnosis for normative systems: Ramos and Fiadeiro's theory of diagnosis developed for organizational process design and Tan and Van der Torre's theory of diagnosis extended with notions of qualitative decision theory. We observe several similarities.
