Results: - Conclusions: The main reasons why myths arise are absence of knowledge and misunderstanding of facts, hiding truth, herd mentality, striving for unity and self-deception. Therefore, we propose to implement the work on demythologization according to the following stages: 1) myth identification, 2) determination of myth characteristics, 3) scientifically substantiated refutation of myth, 4) psychological and pedagogical activities aimed at transforming the mythical worldview. Special attention should be paid to the function which every myth performs: rational, adaptive, security function, mobilizing function, function of history legitimization or means of mass consciousness manipulation. Correct identification of every particular myth and its characteristics will provide finding the most effective pedagogical methods and technologies of demythologization.
