The disunity of cultural group selection

Area of Science:

• Social Sciences
• Evolutionary Biology
• Cultural Anthropology

Background:

• Institutional change is often explained through various mechanisms.
• Group selection is a theoretical framework for understanding evolutionary processes.
• The relationship between demographic processes and group selection requires clarification.

Purpose of the Study:

• To critically evaluate demographic selection, migration, and cultural diffusion as mechanisms of institutional change.
• To determine the extent to which these mechanisms align with the principles of group selection.
• To differentiate these mechanisms from true group selection.

Main Methods:

• Conceptual analysis of institutional change mechanisms.
• Comparative analysis of demographic selection, migration, and cultural diffusion against group selection criteria.
• Literature review on evolutionary theory and social change.

Main Results:

• Demographic selection, migration, and cultural diffusion share minimal commonalities as mechanisms of institutional change.
• These mechanisms typically lack group-level selection pressures that counteract individual-level selection.
• They do not necessitate behavioral altruism or intergroup competition with preferential cooperation.

Conclusions:

• Demographic selection, migration, and cultural diffusion are not synonymous with group selection.
• Cultural norms, while influential, do not constitute group selection.
• A clearer distinction is needed between mechanisms of institutional change and group selection dynamics.
