Norms have proven to be useful mechanisms to coordinate societies. However, when choosing the norms to enact, we should also consider their ethical implications, since the selected norms may promote or demote moral values. Therefore, this selection process must consider how norms relate to moral values as well as the society’s value preferences, so that the chosen norms (the so-called norm system) are those that align best with these preferences. My work studies both quantitative and qualitative methods to compose value-aligned norm systems. Interestingly, the generality of these methods allows to adapt them to many other ethical reasoning and decision making problems.
