Normative data for 8-15 year olds for the Standard Progressive Matrices in Saudi Arabia were obtained in 1977 and 2010. The 2010 sample obtained higher average scores than the 1977 sample by 0.78d, equivalent to 11.7 IQ points. This represents a gain of 3.55 IQ points a decade over the 33 year period.

The relationships between national personality traits and intelligence from 51 countries were examined. It was found that extraversion, openness to experience and agreeableness measured at the national level were significantly and positively correlated with national IQs; however, in the regression model only the former two were marginally…

Cognitive abilities are important for the economic and non-economic success of individuals and societies. For international analyses, the collection of IQ-measures from Lynn and Vanhanen was supplemented and meliorated by data from international student assessment studies (IEA-Reading, TIMSS, PISA, PIRLS). The cognitive level of a nation is highly…

We examine the correlations between the national IQs of Lynn and Vanhanen (Lynn, R. and Vanhanen, T. (2002). "IQ and the wealth of nations". Westport, CT: Praeger. Westport, CT: Praeger, Lynn, R. and Vanhanen, T. (2006). "IQ and global inequality". Athens, GA: Washington Summit Books.) and educational attainment scores in math and science for 10-…
