Two abstracts from the journal Intelligence
The present study was intended to provide perspective, albeit less than unequivocal, on the research of Lynn (2010) who reported higher IQs in the northern than southern Italian regions. He attributes this to northern Italians having a greater genetic similarity to middle Europeans and southern Italians to Mediterranean people. Higher regional IQ was associated with biological variables more characteristic of middle European than Mediterranean populations (cephalic index, eye color, hair color, multiple sclerosis rates, schizophrenia rates). It was maintained, however, that very confident and definitive inferences regarding genetic regional differences in IQ are not warranted. Social conceptualized variables also correlated significantly with IQ so as to suggest the importance of nutrition and economic developmental status more generally.
National IQs and measures of technological development given by Comin, Easterly and Gong (2010) are presented for 133 nations for the year 1000 BC, for 134 nations for 0 AD, for 120 nations for 1500 AD and for 133 nations for 2000 AD. It is shown that national IQs are significantly correlated with national differences in technological development at 0.42 in 1000 BC, 0.18 in 0 AD, 0.63 in 1500 D, and 0.75 in 2000 AD.
I did not find the papers online.
