The Kallikak Family: A Study in the Heredity of Feeble-Mindedness

A scientific publication written in the early 20th century. This work explores the lineage of the Kallikak family to investigate the hereditary factors contributing to feeble-mindedness and other social issues, showcasing how traits may be transmitted across generations. Through careful documentation and research, Goddard aims to highlight the implications of heredity on societal constructs of morality and intelligence. The opening of the book sets the stage for a detailed examination of a specific family, beginning with the introduction of a young girl named Deborah, who enters the Vineland Training School for feeble-minded children. The narrative details Deborah's background, including her troubled family history marked by illegitimacy and social struggles. The initial focus on her personal development and educational progress within the institution serves as a case study to further explore the broader patterns of hereditary feeble-mindedness identified by Goddard through his rigorous fieldwork, which includes tracing the conditions of more than 300 families related to Deborah's lineage. This establishes the foundation for a more extensive investigation into the Kallikak family's ancestry and the social implications of their descent.
