Cultural norms are the unwritten rules and expectations that guide how people behave in a specific society or group. They help individuals understand what is considered acceptable or unacceptable in their community. For example, in many cultures, it is a norm to greet others with a handshake or a smile, which fosters friendliness and connection among people. These norms can vary widely between different cultures. For instance, while eye contact is seen as a sign of confidence in some societies, it may be considered disrespectful in others. Understanding these cultural norms is essential for effective communication and building relationships across diverse groups.
