CONCEPT
Hierarchy of Attachment
Bowlby's structural principle that attachment bonds are organized into a ranking rather than distributed equally — with consequences for how disruption at different levels of the hierarchy produces fundamentally different psychological responses.
The hierarchy of attachment is the organizational principle underlying monotropy. Bowlby observed that infants form multiple attachments but organize them into a clear ranking: one figure at the apex, others at progressively lower positions. The hierarchy serves adaptive functions — the infant turns to the primary figure in greatest distress, to secondary figures in lesser distress, and to the wider social environment in still lower states of activation. Each level provides different quantities and qualities of security. For the AI transition, the framework clarifies why the same technology produces categorically different responses in different people: what determines the response is not the technology but the position in the person's attachment hierarchy of the practice the technology disrupts. Disrupt a subsidiary tool and you produce inconvenience. Disrupt a primary attachment and you produce grief.
