Why do people queue at a bus stop without being told to? Why does it feel strange to face the back of an elevator, or to wear pajamas to a business meeting? The answer is social norms: the shared, usually unwritten rules that guide how people behave in a group. Sociologists study norms because they explain how societies hold together and why some behavior feels “normal” while other behavior feels shocking.
What is a social norm?
A social norm is an expectation about how people should act in a particular situation. Norms tell us what is appropriate, what is rude and what is forbidden. They are learned through socialization: in families, schools, friendships and media, we absorb them long before we can describe them. Most of the time we follow norms automatically, and we notice them only when someone breaks them.
Folkways: everyday customs
The sociologist William Graham Sumner introduced two useful terms in the early twentieth century: folkways and mores. Folkways are the casual customs of daily life, such as greeting people with a handshake, eating with utensils or dressing appropriately for an occasion. Breaking a folkway might cause raised eyebrows, mild embarrassment or a joke, but rarely serious punishment. Someone who shows up to a casual dinner in a tuxedo may get a few comments, and that is the end of it.
Mores: norms with moral weight
Mores (pronounced “MOR-ays”) are norms that a society treats as essential to its moral order. Violating them provokes strong disapproval, because people feel that something important has been betrayed. Examples vary by culture, but they often include norms against betraying a close friend, abusing the vulnerable or disrespecting sacred objects. Mores are taken so seriously that people may feel moral outrage even when no law is involved.
Laws: norms written down and enforced by the state
Some norms are formalized into laws, enforced by institutions such as courts and the police. Not every law matches a strong moral norm, and not every strong norm becomes law. Driving on the right-hand side of the road is a law in some countries and on the left in others; it is a convention backed by official penalties. Laws against theft, by contrast, coincide with deeply held mores.
| Type of norm | How serious is it? | Typical reaction to violation | Example |
|---|---|---|---|
| Folkway | Low | Odd looks, jokes, mild disapproval | Talking loudly in a quiet library |
| Mores | High | Strong moral condemnation, social exclusion | Betraying a trust in a serious way |
| Law | Formal | Fines, legal action, possible imprisonment | Stealing or driving through a red light |
How norms are enforced: sanctions
Societies encourage conformity through sanctions, which are rewards or punishments. Positive sanctions include praise, promotions and awards for following norms. Negative sanctions include criticism, gossip, exclusion and, in the case of laws, formal punishment. Sanctions can also be informal, delivered by friends, neighbors and colleagues, or formal, applied by institutions such as employers and courts.
Interestingly, the strongest enforcement is often internal. Through socialization we internalize norms, and we feel guilt or embarrassment even when nobody is watching. This inner voice does much of the work that external rules could never do.
Norms differ across cultures and over time
Norms are not universal. In some countries, arriving late to a dinner invitation is polite; in others, punctuality is a sign of respect. Gestures, eye contact, personal space and gift-giving customs all vary. Even within a single society, norms change as technology, economics and values evolve. Rules about phone use at the table, remote working clothes or how we address colleagues would have seemed unfamiliar a few decades ago.
Deviance and what it reveals
In sociology, deviance means behavior that violates the norms of a group. It does not automatically mean “bad”: what counts as deviant depends on the time, place and audience. Some deviance is harmful, but some leads to social change, such as challenges to unfair customs. Sociologists study deviance to understand how groups define their boundaries, who has the power to label behavior and how norms are negotiated.
Why understanding norms matters
- Living and working abroad. Awareness of local norms prevents misunderstandings and builds trust.
- Workplace culture. Teams have unwritten rules about meetings, email tone and deadlines. Learning them early helps new employees fit in.
- Public policy and marketing. Campaigns work better when they use, rather than fight against, the norms people already hold.
- Critical thinking. Questioning why a rule exists helps separate sensible customs from outdated habits.
Conclusion
Social norms range from light everyday customs to deeply moral commitments and formal laws, and together they shape how we act, judge and cooperate. By learning to tell folkways, mores and laws apart, you gain a sharper view of society and of your own behavior within it.
