When choosing your next romantic partner, forget about rippling muscles and an outdoorsy tan. Do something really patriotic: pick an intellectual nerd! A new set of findings, recently released online in the journal Psychological Science, suggests that intellectuals are good for the economic health of a country.
To examine the influence of a country's intellectual class on its economy, Heiner Rindermann, a psychologist at the Chemnitz University of Technology in Germany, teamed up with James Thompson of University College, London. The pair carefully analyzed three massive data sets from 90 different countries. Besides examining results from diverse historical periods, they crunched the numbers using several state-of-the-art statistical analysis techniques. What 47 Years Of Marriage Can Teach You

Their analyses led them to this conclusion: having a high IQ intellectual class of people with accomplishments in science, math, technology and engineering translated directly into more wealth for the country. A high-performing intellectual class was also associated with better-developed and freer economic and political institutions, which in turn encouraged more development of the country's "cognitive resources," in what they called a "virtuous cycle."
The free climate becomes a catalyst for creative productivity among the high IQ innovators, who are thus liberated to rethink older ways of doing things, and to expand into new scientific arenas. This, in turn, inspires new technologies, as well as newer and more efficient ways of doing business, and a better climate in which to grow the next generation of innovators.
In developing an equation to predict which countries would be wealthier, the researchers plugged in the average IQ of each country's population as a whole, as well as the average IQ of the "intellectual elite" (the top 5% of the population), and the lowest 5% of the population. Just as countries differ in their distribution of wealth, they also differ in their distribution of IQ. Canada and the U.S. are identical in the IQ of their smartest people (120), but the lowest 5 percent of Canadians are 5 points smarter than the lowest 5 percent of Americans (75 vs. 80).

Rindermann and Thompson found that the IQ measures were all linked to a country's wealth (as measured by GDP), but, when various relevant factors were controlled, it was the IQ of the intellectual elite that was the best predictor. To put it into pure economic terms, an increase of 1 IQ point among average citizens increases a country's average GDP by $229, whereas an increase of 1 IQ point in the intellectual elite is worth $468.
I must admit a bias, given that I am a university professor with government grants to support the high IQ graduate students working in my labs, and someone who teaches classes to bright and eager undergraduates at a state university, many of whom also aspire to future careers in scientific research. Nevertheless, it seems that Rindermann and Thompson's findings have pretty clear implications: if you cut funds for education and for scientific research, you're choking off the system that feeds what has been the world’s most productive "human capital" machine.
