Book excerpt: In Unsettling Assumptions, editors Pauline Greenhill and Diane Tye examine how tradition and gender come together to unsettle assumptions about culture and its study. Contributors explore the intersections of traditional expressive culture and sex/gender systems to question, investigate, or upset concepts like family, ethics, and authenticity. Individual essays consider myriad topics such as Thanksgiving turkeys, rockabilly and bar fights, Chinese tales of female ghosts, selkie stories, a noisy Mennonite New Year’s celebration, the Distaff Gospels, Kentucky tobacco farmers, international adoptions, and more. In Unsettling Assumptions, folkloric forms express but also counteract negative aspects of culture like misogyny, homophobia, and racism. But expressive culture also emerges as fundamental to our sense of belonging to a family, an occupation, or friendship group and, most notably, to identity performativity and the construction and negotiation of power.
