Based on ethnographic research, this book examines the paranormal investigation subculture in the US. Presenting interviews with investigators as well as extensive field observations, it explores their reasons for getting involved, their use of different investigative methods, the interpretive processes by which they individually and collectively 'sense' spirits, the ways in which these processes are influenced by small group power dynamics, and what paranormal investigation ultimately means to those who participate. While focusing on the practices by which investigators 'sense' spirits in small groups, the author also situates paranormal investigation within a broader cultural context and attends to how investigators attempt to legitimize their practice despite being marginalized by both science and religion. A fascinating study of ghosts as an inherently social phenomenon, Sensing Spirits will appeal to sociologists with interests in ethnography, interactionism, cultural studies and subcultures.
