The study of vernacular belief and custom emerged in the early nineteenth century within Romantic Nationalism, which treated folk practices—from superstitions and healing rituals to seasonal customs—as authentic expressions of a national spirit. Early collectors, often antiquarians, documented these elements as cultural treasures. By the late nineteenth century, Anthropological Survivalism, influenced by Edward Tylor and James Frazer, reinterpreted such beliefs as survivals from primitive stages of human thought, seeking universal patterns in magic and religion through comparative methods.
The twentieth century saw a shift toward empirical rigor with the Finnish Historical-Geographic Method, which traced the diffusion and variation of belief narratives across regions. This text-centric approach was challenged mid-century by Contextual Folkloristics, which emphasized performance and social situation, analyzing how beliefs are enacted and serve communicative functions within communities. This paradigm treated customs as dynamic processes rather than static relics, focusing on the immediate contexts of storytelling and ritual practice.
Contemporary frameworks have further diversified. Cognitive Folklore Studies examines the psychological underpinnings of belief transmission, exploring memory biases, conceptual metaphors, and cognitive constraints. Critical and Reflexive Folkloristics interrogates power dynamics, representation, and identity politics in the collection and interpretation of customs, often engaging with postcolonial and feminist critiques. Meanwhile, Digital Folklore has expanded the scope to include online rumors, conspiracy theories, and emergent digital practices, reflecting how vernacular belief adapts to new media environments while retaining folkloric structures.
