It refers to belief systems maintaining that the essential value of an individual person can be determined according to a perceived or ascribed racial category and that social discrimination by race is therefore justifiable. The word it self mean that it appeared in the 1930’s both in English as well as in French. Such discrimination generally includes the belief that people differ in aptitudes and abilities such as intelligence, physical prowess, or virtue according to their races. Many who use the concept of racial categories believe that different races can be placed on a ranked, hierarchical scale. It could also be said as the act of separating groups according to these ascribed race categories. In doing so the term receives the appropriate -ism ending, meaning the practice or act of doing such as described above.
