Final answer:
Optimal Distinctiveness theory proposes that people prefer social identities that achieve the best balance between being a unique individual and being accepted as a group member.
Step-by-step explanation:
The theory that proposes that people prefer social identities that achieve the best balance between feelings of being a unique individual and feelings of being accepted as a group member is Optimal Distinctiveness theory.
According to this theory, individuals strive to maintain a sense of uniqueness and individuality while also seeking a sense of belonging and acceptance within a group.
For example, imagine a high school student who is part of a sports team. They may want to express their own unique talents and skills on the team, but also feel a sense of camaraderie and acceptance among their teammates.
This theory suggests that individuals seek a balance between being their own unique self and being part of a larger social group, as this balance contributes to their overall sense of well-being and identity.
