Since its recognition as a distinctive region in the late 19th century, Appalachia has been a source of enduring myths and distortions regarding the isolation, temperament, and behavior of its inhabitants. Early 20th century writers often engaged in yellow journalism focused on sensationalistic aspects of the region's culture, such as moonshining and clan feuding, and often portrayed the region's inhabitants as uneducated and prone to impulsive acts of violence. Sociological studies in the 1960s and 1970s helped to re-examine and dispel these stereotypes.
