The aim of this article is to consider the psychological mechanisms that may prevent individuals from achieving religious tolerance and religious pluralism. After defining these concepts and explaining why they are desirable outcomes, four psychological obstacles to the achievement of religious tolerance and religious pluralism will be explored by considering both research in psychology and the literature on religious education. The aim of identifying these obstacles is to enable us to suggest how they might be overcome through education, and what the implications for religious education are. (Contains 1 footnote.)
