Social Penetration Theory - Onion Metaphor

Onion Metaphor

Social penetration is perhaps best known for its onion analogy, therefore it is sometimes called the “onion theory” of personality. Personality is like a multi-layered onion with public self on the outer layer and private self at the core. As time passes and intimacy grows, the layers of one's personality begin to unfold to reveal the core of the person. Three major factors influence self-revelation and begin the process of the onion theory, which are personal characteristics, reward/cost assessments, and the situational context.
