The key problem in investigating crimes involving staging is the complexity of identifying the intentional distortion of the physical environment used to mask the true nature of the event. The psychological mechanisms behind a perpetrator’s creation of a "false picture" lead to information noise and the disorientation of the investigation. Existing methodologies do not always account for the subtle connection between the subject's psychophysiological state and the nature of the traces they leave, which complicates the recognition of "negative circumstances" and the identification of the offender's personality through their behavioral signature in the physical environment. The goal of the article is to study the psychological foundations of staging as a specific type of forensic activity, identify patterns in the distortion of the physical environment, and develop criteria for the psychological diagnosis of staging. Particular attention is paid to analyzing the internal mechanism of forming a false alibi through material objects and identifying the typical "psychological lapses" of a perpetrator when modeling a crime scene. The study utilizes the systemic-structural method, the method of psychological modeling, the comparative-analytical method, and an analysis of expert and investigative practice. The theoretical framework is composed of works on forensic technology and judicial psychology, which allowed for the synthesis of knowledge regarding material traces and the mental processes of the subject who left them. The analysis revealed patterns in the emergence of "informational contradictions" between the ideal model of the crime in the mind of the perpetrator and its physical manifestation. It was established that the redundancy or demonstrativeness of traces is often a consequence of psychological tension and the subject's drive for hypercompensation. It is proven that identifying signs of staging should be based on searching for inconsistencies between the objective logic of the event's progression and the perpetrator's subjective perceptions of the scene's "plausibility." Solving these problems will increase the efficiency of crime scene examinations, reduce the time required to expose the guilty, and minimize the risk of investigative errors caused by artificially created versions. The findings contribute to the development of the forensic doctrine of staging and the improvement of the tactics of investigative actions.
