Disease affects IQ the most

Genetic and educational characteristics are often thought to have the greatest impact on intelligence, but a new study found that illnesses affect IQ more than both.

According to the Daily Mail , scientists at the University of New Mexico analyzed IQ across the United States and concluded that having infectious diseases has a big impact on the power of the brain. The cause of this is because people, especially children, spend a lot of energy to maintain brain activity. If the disease disperses this amount of energy, intelligence is certainly negatively affected.

In an article published in the American scientific journal, researcher Christopher Eppig said: " Infectious disease is a factor that can deprive a large amount of energy from a developing brain. Evidence shows, the disease Transmission is a major cause of global IQ differences. "

Eppig's team examined various hypotheses about the factors affecting IQ, including education, wealth and the idea that people live farther away from the sub-region. Sahara, more intelligent. After conducting IQ research throughout the United States, Mr. Eppig and his colleagues rejected all of these assumptions.

Researchers point out that the US states have the lowest 5 average IQs and have a higher rate of infectious diseases than the states with the 5 highest average IQs. This relationship is also very clear for all the remaining states.

"If the key factor is genes like some people suggest, IQ is very difficult to change," Eppig stressed. He and his colleagues expressed hope, their research results will allow those who want to increase IQ can do something more effective.
