Morality vs. Convention

Shweder et al. (1987) contrast social conventions and moral rules cross-culturally. They conclude that the category of social convention emerges from the moral concept of individual rights and is not found in cultures that lack this concept.

Shweder et al. would give a more complete analysis if they discussed informal social rules. These rules are unmarked by culture and are learned through mimicry.  People may feel uncomfortable upon witnessing another person violating these informal rules. However, they are unlikely to know why.

Shweder et al. support their conclusions using data collected via structured interviews in Hyde Park, IL and India.
