The functional brain architecture of human morality

Area of Science:

• Cognitive Neuroscience
• Social Psychology

Background:

• Human morality underpins societal structures, influencing laws and social interactions.
• Recent advancements in cognitive neuroscience aim to elucidate the neural underpinnings of moral cognition.

Purpose of the Study:

• To present an emerging model of the neural basis of human morality based on recent cognitive neuroscience research.
• To explain how automatic neural processing and social emotions contribute to moral decision-making.

Main Methods:

• Review of recent findings in cognitive neuroscience research on morality.
• Theoretical modeling of neural circuit competition and conscious experience of moral judgment.

Main Results:

• Moral judgments involve automatic evaluation by parallel neural circuits, often associated with social emotions.
• Decision-making results from a competitive process among these neural circuits.
• Conscious moral sense involves subjective experience and post hoc rationalization of decisions.

Conclusions:

• Human morality is rooted in complex neural processes involving automatic evaluation, emotional input, and conscious interpretation.
• Understanding the neural basis of morality offers insights into societal functions and individual behavior.
