It has been argued that human intelligence is a measurable variant as stated in the book "The Bell Curve" by psychologist Richard J. Herrnstein and political scientist Charles Murray. A series of intelligence quotient (IQ) studies carried out from 2002 to 2006 by Richard Lynn, a British Professor of Psychology, and Tatu Vanhanen, a Finnish Professor of Political Science, were summaried in their books such as "IQ and the Wealth of Nations", "IQ and Global Inequality" http://www.rlynn.co.uk. Based on their analysis, they argue that differences in national income are correlated with differences in the average national IQ. They further argue that differences in average national IQs constitute one important factor, but not the only one, contributing to differences in national wealth and rates of economic growth. In this presentation, I will use datasets collected from different public resources to exhibit an intuitive correlation between national averaged IQ and GDP per capita.
