What does the Social Penetration Theory suggest about relationships?

The Social Penetration Theory suggests that as relationships develop, individuals move from superficial layers of communication to deeper, more intimate ones. This theory is often depicted as a "onion" with different layers representing various levels of personal information. Initially, interactions may consist of basic, non-intimate exchanges, but as trust and closeness build over time, individuals begin to share more personal thoughts, feelings, and experiences.

This progression emphasizes the idea that intimacy grows with self-disclosure and mutual vulnerability, leading to stronger and more meaningful connections between individuals. Ultimately, the theory highlights the importance of depth in disclosures as relationships mature, illustrating how communication can evolve from surface-level conversations to more profound exchanges that foster emotional closeness.
