It is noted that for the purposes of forecasting, it is necessary to focus not on abstract perspective knowledge, but on objects, processes and phenomena directly related to the implementation of forensic activities and reflecting its specifics. The inclusion of phenomena included in the subject of research of other sciences in the number of objects of expert forecasting is critically assessed on a specific example.
