The paper examines the key concepts of the study: personality, identification, trauma, gender, and anomaly. The scientific novelty of the work lies in the recognition of the connection between a traumatic experience of interaction and non-normativity in the nature of personal identification. As a result, a thesis is put forward stating that the presence of non-normative elements in the structure of personal identification is determined by a traumatic experience. The proposed idea creates the possibility of identifying the dual (normative and non-normative) nature of various forms of personal identification.
