Normative commitments may only contingently supervene on interests. [causal]
Finally, note that there may be a disanalogy between supervenience in the theory of mind and the psychological supervenience of normative commitments on interests. There may be no necessary connection in the latter. For example, we might suppose in many cases that people have learned to have normative reactions to particular matters and that this is their first motivation in many actual instances.
QUESTION: Potential disanalogy between mental supervenience and normative supervenience — whether normative reactions are learned rather than necessitated by interests is worth pursuing.
