The average British- scaled IQ of this sample is estimated to be at or below 55. Key words: South Sudan, Standard Progressive Matrices, Intelligence, IQ tests, Refugees. The southern part of Sudan seceded to become the independent nation of South Sudan in July, 2011. The principal reason for this secession was that the people of the southern part of Sudan are ethnically different from those of the center and the north. A genetic analysis by Cavalli-Sforza, Menozzi and Piazza (1994, Figure 3.9.1, p. 181) showed that the South Sudanese are principally a Nilotic people, one of the four sub-races of Negroids (Baker, 1974, p. 329), while the people of central and northern Sudan are a mixed race population consisting principally of North African Caucasoids (K.C.B., 1960, p. 512-3).
