Shrink Definition
The proximity effect is the tendency to form relationships with people we're physically or routinely near. Repeated, easy contact with neighbors, classmates, or coworkers builds familiarity and friendship. Who is nearby shapes who becomes close, often more than we credit. Presence, not just personality, drives connection.
