Answer:
social norm
Explanation:
Social norms are the usual rules of behavior that regulate our interactions with others. They also refer to the group's set of expectations for appropriate thoughts and behaviors of its members. Since a particular way of doing things is established as a general rule, the social norm tends to remain in force because its follow-up allows one to predict how others will behave and better coordinate interaction between different people.
Social norms involve our social nature and our daily life in community. Knowing that others are fulfilling it provides a benchmark against which people can compare different options when they are unsure of what to do.
