>> Thus the Jukes were characterized by a large proportion of criminals, the Ishmaelites of Indiana by paupers, the "Zero" family of Jörger (1908) by vagrants, the family described by Poellmann by prostitutes and procurers, the Nams, as we shall see, by alcoholism and lack of ambition. The rural communities of "degenerates" usually have this in common: an unusual lack of industry, retardation in school work, and a failure to observfe the conventionalities in sex-relationships. There is reason for concluding that the first and second traits are hereditary and are, in a measure, the raison d'etre of the foundation of such communities. The last may be, in large measure, due to the remoteness of the community from social influences. (p. 1) <<
