In a word, the social comparison theory states that we evaluate ourselves in relation to others in order to broaden and/or improve our frame of reference.
When objective measurements are absent or not thought to be important, it ostensibly serves as a reality check. On the plus side, the comparison might provide a framework for "information collecting." Without the example of other individuals, we might not even realize what is even possible. Our perception of what we can conceive for ourselves can be expanded by looking at other people's examples. It motivates us to achieve excellence. We have the chance to get closer to perfection by seeing others practice it. We learn about what's effective when we observe someone or an organization accomplishing its objectives. By extending our casing of reference and applying what we gain from this perception, we gain ground toward our own proficient objectives.
