A nameless girl, a fleeting encounter, and a fabricated bloodline that rewrote American history. In 1912, the infamous “Kallikak” study turned a story about lust into a nationwide crusade to police sex, purity, and who was allowed to have a family. What followed reshaped institutions, courtrooms, and the lives of thousands labeled “unfit.”

Drawing from archival records and later investigations, this episode unravels how a moral panic became “science,” how heredity became a weapon, and how one myth helped justify decades of control over the bodies of women, the poor, and the institutionalized.
