The journal of Personality and Individual Differences remains a bastion of hereditarianism, which is perhaps not surprising given that Tony Vernon, who has co-authored a number of papers with Phillip Rushton, and Sybil Eysenck, widow of Hans Eysenck, are the Editors-in-Chief. Here are a few articles in press:
Allik, 2011. National differences in personality
Besides establishing national IQ levels, Richard Lynn also started and inspired studies attempting to find out regularities behind the national differences in personality. Recent large-scale collaborative projects involving hundreds of psychologists from about 50 countries allowed for determination of the aggregate national scores of personality for the most popular personality models, including the Big Five. These studies have already revealed several universal and geographically regular patterns in the global personality trait distributions. The area of the study of national differences in personality has arguably matured to a level where it can start to help solving fundamental problems such as the relationship between genes, culture, and personality.
Cognitive ability theory claims that peoples’ competences are decisive for economic wealth. For a large number of countries Lynn and Vanhanen (2002) have published data on mean intelligence levels and compared them to wealth and productivity indicators. The correlation between intelligence and wealth was supported by studies done by different authors using different countries and controls. Based on their pioneering research two research questions were developed: does intelligence lead to wealth or does wealth lead to intelligence or are other determinants involved? If a nation’s intelligence increases wealth, how does intelligence achieve this? To answer them we need longitudinal studies and theoretical attempts, investigating cognitive ability effects at the levels of individuals, institutions and societies and examining factors which lie between intelligence and growth. Two studies, using a cross-lagged panel design or latent variables and measuring economic liberty, shares of intellectual classes and indicators of scientific-technological accomplishment, show that cognitive ability leads to higher wealth and that for this process the achievement of high ability groups is important, stimulating growth through scientific-technological progress and by influencing the quality of economic institutions. In modernity, wealth depends on cognitive resources enabling the evolution of cognitive capitalism
Templer, 2011. Richard Lynn and the evolution of conscientiousness
The scientific style of Lynn is described and includes his tenacity combined with his creativity, his research intuition, and his ability to politely correct the scientifically incorrect. His empirical and theoretical contributions to conscientiousness as a function of intelligence, race, and psychopathic personality in an evolutionary context are described and discussed. This is related to his work on pigmentocracy and to recent research showing more aggression in dark animals and humans. Suggestions for measurement of psychopathic personalities are offered.
Meisenberg, 2011. National IQ and economic outcomes
One of the most consequential parts of Richard Lynn’s work is the establishment of a comprehensive data set of ‘‘national IQ’’ for nearly all countries in the world. The present contribution demonstrates the use of this database for the explanation of two economic outcomes: (1) economic growth and level of attained wealth at the country level; and (2) income distribution in countries as measured by the Gini index. The results show that high IQ is associated not only with high per-capita GDP and fast economic growth, but also with more equal income distribution. These outcomes are not mediated by educational exposure.
