The "looking-glass self" is undoubtedly Cooley's most famous concept, and is widely known and accepted by psychologists and sociologists today. It expanded William James's idea of self to include the capacity of reflection on its own behavior. Other people's views build, change and maintain our self-image; thus, there is an interaction between how we see ourselves and how others see us. Through these interactions, human beings develop an idea of who they are. He argued that when we feel shame or pride, it is due to what we think others view us as. He also mentions that we do not always perceive someone's impressions correctly. For example, if a student incorrectly answers a question in class, they might later question their own intelligence or capacity to prepare sufficiently. The notion of the looking-glass self applies throughout an individual's life: interactions with new people time and again encourage self-evaluation based on a presumed impression given off. In other words, one's self-identity can be socially constructed.
