The Dillingham Flaw is a term coined by U.S. sociologist Vincent N. Parrillo to identify a centuries-old phenomenon of faulty logic when nativists misinterpret and react negatively to the presence of immigrants in their midst.
Filipino laborers frequenting pool halls or attending street fairs in Stockton, Dinuba, Exeter, and Fresno risked being attacked by nativists threatened by the swelling labor pool as well as the Filipino's presumed predatory sexual nature.
