This study advocates for integrating immediate moral reasoning with culturally-evolved moral norms. It proposes viewing norms as adaptive joint programs, not rigid byproducts, reflecting historical resource-rational decision-making.
Area of Science:
- Moral Psychology
- Cultural Evolution
- Behavioral Economics
Background:
- Culturally-evolved moral norms are often viewed as rigid byproducts of evolutionary processes.
- Integrating in-the-moment moral reasoning with established moral norms presents a theoretical challenge.
Purpose of the Study:
- To propose a more integrative account of culturally-evolved moral norms.
- To advocate for continuity between immediate moral reasoning and societal moral standards.
Main Methods:
- Conceptual analysis of existing theories on moral norms and cultural evolution.
- Development of an alternative framework viewing norms as culturally-evolved joint programs.
Main Results:
- Culturally-evolved norms can be understood as dynamic, resource-rational joint programs.
- This perspective offers a more nuanced view than norms as mere byproducts of blind selection.
Conclusions:
- Viewing moral norms as adaptive, historically-informed joint programs enhances understanding of their continuity with individual moral reasoning.
- This integrative approach supports the proposal for greater coherence between immediate ethical judgments and societal moral frameworks.
