The regulation of public relations is based on social norms. Society establishes these norms in order to regulate human behavior in society, they tell us: this is right and this is not, this is possible, but this is not possible, this is good, and this is bad. Social norms include: morality, law, religion, etiquette, fashion, etc. In addition, society imposes sanctions, they can be positive and negative, formal and informal. For example, for participating in the Olympiad you received a diploma of a prize-winner, this is a formal positive sanction, the boss reprimanded a subordinate or reduced his salary – a formal negative one. The grandmother thanked you for your help – informal positive, mother scolded – informal negative.
The most important social relations are regulated by the state with the help of legal norms.
