Mos are norms deemed highly necessary to the welfare of a society because they embody the most cherished principles or core values of a group, often carrying strong moral connotations and associated with intense feelings of right and wrong. They are informal rules of conduct that dictate what is considered morally acceptable or unacceptable behaviour, and violations of mores typically evoke strong social disapproval, condemnation, or even severe sanctions. Examples of mores in many societies include prohibitions against theft, murder, and incest. Mos are often deeply ingrained in a culture and are transmitted through socialisation across generations, contributing to social stability and the maintenance of ethical standards. They differ from folkways, which are also informal norms but govern everyday social behaviour and whose violation raises comparatively little concern.
