The article deals with the concept of metaparasite in the cultural and communicative sphere. Relying on the memetic theory of R. Dawkins and the cognitive framework proposed by K. Anokhin, the authors explore the dynamics of metaparasitism and the ability of the metaparasite to change its environment beyond the original context. The article also considers the challenges that have emerged in the post-truth era, embodied in such phenomena as fake news, etc., and emphasizes the need to find effective (...) responses to threats to psychological and sociocultural security. The article formulates a set of communicative techniques aimed at ensuring safety for both the communicator and the recipient, and presents the feedback system as a key component of any rational system. Based on the results of the study, the authors propose a strategy aimed at protecting society against the harmful effects of metaparasites. (shrink)
