Green beards and signaling: Why morality is not indispensable.

Area of Science:

• Evolutionary Psychology
• Moral Philosophy
• Social Norms

Background:

• Human cooperation is a complex phenomenon.
• The role of objectivist moral attitudes in facilitating cooperation is debated.
• Existing theories often link high cooperation to shared moral frameworks.

Purpose of the Study:

• To investigate whether objectivist moral attitudes are necessary for high levels of human cooperation.
• To explore alternative mechanisms that can explain human cooperative behaviors.
• To challenge the necessity of objectivist morality in evolutionary accounts of cooperation.

Main Methods:

• Analysis of evolutionary models of cooperation.
• Examination of theoretical frameworks explaining social norms.
• Review of empirical evidence on human behavior and cooperation.

Main Results:

• Evolutionary models suggest mechanisms beyond objectivist morality can support cooperation.
• Conventional social norms appear sufficient to explain extreme cooperative behaviors.
• Objectivist moral attitudes are not a prerequisite for high levels of human cooperation.

Conclusions:

• High levels of human cooperation can be achieved without strict adherence to objectivist moral attitudes.
• Social norms and other evolutionary mechanisms play a significant role in enabling complex cooperation.
• Rethinking the necessity of objectivist morality offers new perspectives on human sociality.
