On the perceived objectivity of some moral beliefs

This paper presents research in moral psychology and draws on this research to offer an account of the cognitive systems and processes that generate the perceived objectivity of some moral beliefs. It presents empirical research on the perceived objectivity of moral beliefs, compares different algorithms employed by human cognition in the context of model-free and model-based reinforcement learning, and uses concepts drawn from dual-system and modular theories of cognition. The central claim of the account is that belief in the objectivity of some moral beliefs results from certain ‘modular’ features of cognitive systems.
