Recent years have seen an increased interest in the construction and exploitation of ignorance, with the establishment of a field of agnotology (ignorance studies). This effort has focused almost exclusively on governments and corporations, though little or none on religion. After exploring work in agnotology and introducing the concept of agnomancy (the creation or conjuring of ignorance), the present article offers a preliminary application of these perspectives to religion, investigating what light agnotology sheds on religion and when and for what reasons religion engages in agnomancy.
