Differences between folkways, mores, and laws primarily relate to their level or extent of formality and the consequences of non-compliance. Folkways are informal rules or daily customs whose contravention does not attract severe consequences.
Conversely, mores are informal but firmly held standards within a particular culture, with moral and ethical undertones that may attract severe reprisals if violated. Law, as Kendall explains, comprises formal rules and dictates enacted by an elected legislature, enforced by the government, and with an assurance of sanctions if contravened.
