We as people have many different roles within our life, these roles serve many different purposes. We also we find we belong to different groups in which we play our different roles, this makes up our social identity. It is these groups that can have a negative or a positive effect on ourselves. We can be part of the “in group” or the “out group” depending on somebody's experience of the membership of that group, sometimes groups maintain an us and them mentality when it comes to being part of it. The norms of the group are expected to be adhered to by members, and this can lead to members being expected to conform, non conformity can often lead to role conflict and group pressure to follow the rules, and ultimalty if the overall effect is negative or positive.
