Freud's repetition compulsion concept is reviewed and examined critica
lly. It has been used as an explanatory concept to cover a wide variet
y of clinical phenomena similar only in their manifest repetitive qual
ity, and it appears frequently in psychoanalytic and psychiatric liter
ature. Its relationship to trauma and post-traumatic stress disorder i
s Explored. Emphasis is on the detrimental technical legacy of the con
cept, which has cast a pessimistic aura of unanalyzability over a wide
variety of repetitive phenomena, especially analyzable resistances re
lated to aggressive conflicts. We conclude that the repetition compuls
ion is an anachronistic concept with detrimental technical implication
s and that it should be retired.
