 Masaryk and Beneš took the initiative of calling for a conference to re-establish in the minds and consciences of men everywhere the truth about race ... Nazi propaganda was able to continue its baleful work unopposed by the authority of an international organisation.The Third Reich's racial policies, its eugenics programs and the extermination of Jews in the Holocaust, as well as the Romani people in the Porrajmos (the Romani Holocaust) and others minorities led to a change in opinions about scientific research into race after the war.Changes within scientific disciplines, such as the rise of the Boasian school of anthropology in the United States contributed to this shift.
