4.1.3 (HL)—Culture and relationships

Self-disclosure is revealing personal information to another person. Social penetration theory describes a possible progression from broad, low-risk facts towards narrower and more intimate material as trust and reciprocity develop.

The amount and depth disclosed depend on the recipient, relationship stage, information sensitivity, mood and purpose. Disclosure may build intimacy because it signals trust and invites reciprocal sharing, but it is not a fixed rule for every relationship.

Collins and Miller’s meta-analysis found an association between disclosure and liking. That supports a relationship between the variables, not a guarantee that disclosure causes closeness: self-report measures, study designs and cultural expectations also matter.

The ‘onion’ metaphor is a model, not a universal sequence. Collectivist norms or a different relationship context may make deep personal disclosure inappropriate; distinguish correlation, subjective measurement and cultural scope before generalising.

A cross-cultural communication strategy is to make interpretation explicit: describe the behaviour rather than assigning motive, ask how the message is understood locally, paraphrase the response, and negotiate expectations about directness, privacy and disclosure. Its success should be evaluated through mutual understanding and relationship outcomes, not by forcing one partner to adopt the other culture's style.
