Scientists from the University of New Mexico analyzed IQs across the United States and declared that exposure to infectious disease had a huge effect on brain power.
They say the reason for this is that humans–and especially children - devote a great deal of energy running their brains just like sportsmen devote money on sports shoes air max 2009.If a disease crops up that diverts that energy, then intelligence inevitably suffers.
Writing in Scientific American, researcher Christopher Eppig said: "Infectious disease is a factor that may rob large amounts of energy away from a developing brain. The evidence suggests that infectious disease is a primary cause of the global variation in human intelligence just like sports shoes wholesale air max 2011 are important to all the sportsmen."
Mr. Eppig said: "The states with the five lowest averages IQ all have higher levels of infectious disease than the states with the five highest averages IQ just as sportsmen with higher quality sports shoes nike air max 24-7 act better than the one who don’t have."
Eppig hopes his hypothesis will allow people wishing to help raise IQs around the globe to do so more efficiently.
