The paper features relations between extremist attitudes and moral sphere. The study was based on J. Haidt’s Moral Foundations Theory. Most researchers are interested in the problem of right-wing extremist attitudes, e.g. xenophobia, nationalism, religious fanaticism, authoritarianism, etc. However, the existing evidence of the link between such attitudes and some particularities of the moral sphere doesn't take into account modern psychological approaches toward moral. On the basis of moral foundations theory, the authors hypothesized that binding moral foundations may be linked with rightwing extremist attitudes. This hypothesis was tested on 397 university students (women – 83 %). The participants answered the Moral Foundations Questionnaire by J. Graham et al. and Young Men Extremist Attitudes Questionnaire by K. V. Zlokazov. The results of the correlation analysis showed that individualizing moral foundations (Harm and Fairness) were inversely correlated with right-wing extremist attitudes, while binding moral foundations (Loyalty and Authority) showed direct correlation. Such moral foundation as Sanctity showed contradictory correlations with extremist attitudes. Using structure linear modeling the authors demonstrated the significant impact of two moral foundations (Authority and Harm) on extremist attitudes. Authority was associated with a relatively high level of religious fanaticism, xenophobia, and authoritarianism. Care was associated with a low level of fanaticism, xenophobia, and nationalism. The obtained results proved that such violencecondemning values as care and harm avoidance oppose right-wing extremist attitudes. However, such values as respect for authorities and traditions may have potentially negative side effects, e.g. justification and support of right-wing extremist attitudes.
