A study that has been discussed by the Economist Magazine here established that the prevalence of infectious disease correlates highly with intelligence and a society's development. As expected the study by scholars from the University of New Mexico confirmed that tropical countries and Africa in particular has a high burden of infectious disease and that this is related to the level of intelligence measured by Intelligence Quotient (IQ).
The exact findings of the study is that a huge disease burden affects the intelligence of people within that geographical area and in turn undermines economic development. Taken ahead, this view suggests that geography has substantial implications for economic development. As explained, this inverse relationship between the disease burden and the average IQ. infectious pathogens that cause malaria for instance, affects cognitive development of children.
The place of IQ in economic development has separately been explored by Garett Jones and W Joel Schneider in the paper with the title: Intelligence, Human Capital and Economic Growth. In it Garett and Joel find that a 1% increase in average IQ increases a nation's GDP per capita by 0.11%. That led me to think that its all about education and yet this paper introduces public health questions in it. Two papers worthy of sending to Minister of health, education and finance for holiday reading.
