The possibilities of the semantic analysis technique developed in linguistics and used in working with texts for the tasks of psychological study of the professional activities of specialists are substantiated. On the example of the study of risk perceptions in the work of police psychologists and practicing psychologists and teachers of the university, the advantages and limitations of the methodology are shown. The similarity of the structures of perceptions of the risk of professional activity among psychologists has been ascertained: emotional burnout and professional deformation, the use of psychological assistance methods, fear of error, legal liability, proper interaction with the client, relationships with colleagues. Double differences in the levels of professional risk reflection, the banality of risk ideas, and the harmony of the structure of representations (“Zipf’s Law”) are revealed. All indicators are optimal for police psychologists. It is concluded that it is advisable to use the methods of semantic analysis as an express risk diagnosis in professional activities.
