Compartmentalization is an unconscious psychological defense mechanism used to avoid cognitive dissonance, or the mental discomfort and anxiety caused by a person’s having conflicting values, cognitions, emotions, beliefs, etc. within themselves.

Compartmentalization allows these conflicting ideas to co-exist by inhibiting direct or explicit acknowledgement and interaction between separate compartmentalized self states.[1]

Psychoanalytic views[edit]

Psychoanalysis considers that whereas isolation separates thoughts from feeling, compartmentalization separates different (incompatible) cognitions from each other.[2] As a secondary, intellectual defense, it may be linked to rationalization.[3] Related also is the phenomenon of neurotic typing, whereby everything must be classified into mutually exclusive and watertight categories.[4]

Otto Kernberg has used the term bridging interventions for the therapist’s attempts to straddle and contain contradictory and compartmentalized components of the patient’s mind.[5]


Compartmentalization may lead to hidden vulnerabilities in those who use it as a major defense mechanism.[6]

Those suffering from borderline personality disorder will often divide people into all good versus all bad, to avoid the conflicts removing the compartments would inevitably bring, using denial or indifference to protect against any indications of contradictory evidence.[7]

Using indifference towards a better viewpoint is a normal and common example of this. It can be caused by someone having used multiple compartment ideals and having been uncomfortable with modifying them, at risk of being found incorrect. This often causes double-standards, and bias.
