For a large Available online 23 July 2011 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 Keywords: was supported by studies done by different authors using different countries and controls. Based on their Intelligence pioneering research two research questions were developed: does intelligence lead to wealth or does Economic growth wealth lead to intelligence or are other determinants involved? If a nation’s intelligence increases wealth, Wealth how does intelligence achieve this? To answer them we need longitudinal studies and theoretical GDP attempts, investigating cognitive ability effects at the levels of individuals, institutions and societies Technology Smart fraction theory 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 indi- cators 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 sci- entific-technological progress and by influencing the quality of economic institutions. In modernity, wealth depends on cognitive resources enabling the evolution of cognitive capitalism. Ó 2011 Elsevier Ltd. All rights reserved. 1. Introduction: The wealth of nations cultural orientations supporting hard and systematic work, educa- tion towards useful knowledge and thinking, meritoric principles, Since Adam Smith many scholars have tried to explain why and efficiency. Such orientations are stressed in religious traditions some nations are richer than others. Two principal paradigms (Protestantism, Confucianism, Judaism), in enlightenment and in a could be distinguished: in the first the causes are found in a nation burgher culture (Weber, 2001/1905; Mokyr, 2010).
