It is first shown from the factor analytic studies of eight investigators that groups of attitudes, objectively measured, mark some six ergs ('instincts') as unitary factors. It is then shown that in addition to the high markers certain other attitudes load these factors in anomalistic low degrees. These indicate connections that may not be clinically easy to perceive or verify. A theory is developed that a more 'dense' data base could yield primary factors below the general ergic factor, that represent Freudian and other concepts of polymorphously perverse instinctual fixations. A basis of separation of ordinary low loaded attitudes from such perversion manifestations is thus a suggested possibility.
