Lynn (2010a, 2010b) argued that individuals from south Italy have a lower IQ than individuals from northItaly, and that these differences in IQ are at the basis of north–south gap in income, education, infant mortality,stature, and literacy. In the present paper, we discuss several theoretical and methodological aspectswhich we regard as flaws of Lynn's studies. Moreover, we report scores of southern Italian children onRaven's Progressive Matrices and a north–south comparison for the PASS theory of intelligence as measuredby the Cognitive Assessment System (Taddei & Naglieri, 2006). Both results reveal similar levels of performanceof northern and southern Italian children in fluid intelligence and PASS (Planning, Attention, Simultaneous,and Successive) cognitive abilities.
