Research has found that people who consider themselves to be high in disclosure are likely to be good at eliciting more disclosure from those with whom they interact. Three theories describe reciprocity: The social attraction-trust hypothesis, social exchange theory and the norm of reciprocity. The social attraction-trust hypothesis says that people disclose to one another because they believe the person who disclosed to them likes and trusts them. Social exchange theory explains that people attempt to maintain equality in self-disclosure because an imbalance in this makes them uncomfortable. The third explanation, the norm of reciprocity, argues that reciprocating disclosure is a social norm and violating it makes a person uncomfortable.
