Norms are the unwritten rules and expectations that guide behavior within a group or society. They help individuals understand what is considered acceptable or unacceptable in various situations. Norms can vary widely between different cultures, communities, and social groups, influencing everything from communication styles to dress codes. These social guidelines can be formal, like laws, or informal, like traditions and customs. Norms play a crucial role in maintaining order and cohesion within a group, as they encourage conformity and discourage behaviors that might disrupt social harmony. Understanding norms is essential for effective interaction in any social setting.
