Explanation:

Social interaction is important to the way that societies are constructed. Generally, social interaction is studied in groups of two people (dyads), three people (triads), or in larger social group relations. It is in our interactions that we develop norms and systems of interaction with one another as a wider society. We use symbols and language in order to communicate in our interactions and exchanges.  

Social groups share certain characteristics like a common identity and this sometimes leads to behaviors and holding beliefs that are exclusionary to outsiders. Ethnocentrism is an example where people of a group might have a fear or bias of people from other cultures. Groups that have a lot of diversity tend to be more tolerant of outsiders and different cultures because they are familiar with diversity in their daily lives and social interactions.
