According to sociologists, there is a correlation between a group's:
a. cultural diversity and its interaction with outsiders.
b. purpose and peer pressure on members.
c. physical boundaries and education level.
d. size and purpose.

A. cultural diversity and its interaction with outsiders.

In the context of symbolic interactionism, it the study of human conduct and human life. How one’s social life is formed and is being described by one’s perspective of self and others –community, society and etc. In this approach, these 3 views were asserted by Herbert Blumer (1969) as follows: 
1.       People act on a specific object based on how they see or construe it according to their outlook and attribution on the object. 
2.       These certain outlooks and attribution that has been formed by an individual is shaped and reinforced by the people this individual is exposed to. 
3.       These outlooks and attribution are continuously changed and altered based on one’s social environment.

A - cultural diversity and its interacion with outsiders.

The more diverse one culture is in terms of its own cultural boundaries, the more it will also interact with members of another and different culture. This goes the other way around as well - the less diverse a culture is, the less it interacts with outsiders.
