St. Petersburg academic psychiatrist professor Yuri Nuller notes that the concept of Snezhnevsky's school allowed psychiatrists to consider, for example, schizoid psychopathy and even schizoid character traits as early, delayed in their development, stages of the inevitable progredient process, rather than as personality traits inherent to the individual, the dynamics of which might depend on various external factors. The same also applied to a number of other personality disorders. It entailed the extremely broadened diagnostics of sluggish (neurosis-like, psychopathy-like) schizophrenia. Despite a number of its controversial premises, but in line with the traditions of then Soviet science, Snezhnevsky's hypothesis immediately acquired the status of dogma, which was later overcome in other disciplines but firmly stuck in psychiatry. Snezhnevsky's concept, with its dogmatism, proved to be psychologically comfortable for many psychiatrists, relieving them from doubt when making a diagnosis.
