In psychology, a family nexus is a common viewpoint held and reinforced by the majority of family members regarding events in the family and relationships with the world. The term was coined by R. D. Laing, who believed that this nexus "exists only in so far as each person incarnates the nexus...maintaining his interiorization of the group unchanged".[1]
The concept is similar to the "family psychic apparatus (FPA)...an unconscious psychic basis, common to members of the family group, inducing a specific experience of belonging".[2]
