The current paper investigates the notion of protective communication represented by systems of signs, texts, rituals which the authors regard as means of neutralizing cognitive constructs, generated by phobias of varying degrees of irrationality. Classification of phobias on psycho- and sociolinguistic grounds allows developing their typology from the point of view of the cause of their origin: supernatural entities (superstition), individual fearful images (prejudice), social suspicion (bias). As the study showed, sacred horror caused by destructive forces of nature, climatic phenomena not subjected to man, and astronomical events gave rise to supernatural, esoteric phobias reflected in superstitions. Biological phobias appeared in response to real dangers, associated with daily human activities, personal imaginary troubles and fears, which generated a system of prejudice invented by man himself. Social interaction of people, with its negative stereotyping and categorization of social space, entailed a wide range of phobias (racial, religious, age, gender, etc,) which turned into social biases. On his way of development, a man tried hard to find protection against phobias of different nature, creating an extensive system of protective means incorporated in religious, magical and intolerant types of discourse, consequently neutralizing superstitions, prejudices and biases in specific genres, verbal and non-verbal signs, texts and rituals of the above mentioned types of discourse.
