This study examines sex differences in reasoning ability assessed with Raven’s Advanced Progressive Matrices among 2,206 (1001 male and 1205 female) school students aged between 15 and 18 from urban and rural secondary schools in the Minya region of southern Egypt. There are no statistically significant differences in intelligence between males and females up until the age of 15. However, males scored significantly higher than females at the ages of 16, 17 and 18, consistent with Lynn’s developmental theory of sex differences in intelligence. In exploring the Egyptian education system and the social dynamics of the Minya region in more depth, we attempt to find various confounds which might offer explanations for this difference. However, we find that Lynn’s model is the most persuasive.
