The article considers the theory of „new ethics“ within the framework of the modern poetic discourse demonstrating issues of tolerance, harassment and cancel culture. Misinterpretations of these concepts, due to cognitive bias, can lead to communicative failures, as poetry is viewed as one form of multilateral dialogue. This dialogue is characterized by the presence of an addresser (the author of the poetic internet text), an addressee (the reader), communicative mechanisms determined the act of communication. The aim of research is to identify the types of cognitive bias that may become causes of communicative failure in the modern German and Russian poetic internet texts demonstrating the concept of „new ethics“. Methodology and research methods. The research work used methods of systematization and generalization of the scientific material, descriptiveanalytical method, method of linguistic and stylistic analysis of the text Results. The research shows that the causes of communicative failures in poetic discourse are certain types of cognitive bias, such as „focusing effect“ (the recipient's attention is concentrated on specific lexemes rather than the overall text content), „discounting the positive“ (the recipient ignores the positive aspects of the theme discussed in the poem), „catastrophizing“ (the recipient fixates on the negative development of situation presented in the poem ), „emotional reasoning“ (the recipient ignores the conclusions made by the author of the poem due to their corresponding emotional state). This fact also determines the relevance of the study. Scientific novelty lies in the study of the principles of „new ethics“ within the framework of the modern poetic discourse, as well as in identifying the types of cognitive bias characteristic of poetic internet discourse. The practical significance is determined by the possibility of using the obtained scientific results in special university basic courses on cultural linguistics, discourse theory, linguistic and stylistic interpretation of the text, cognitive linguistics
