Human Intelligence Decling

Stanford University researcher and geneticist, Dr. Gerald Crabtree, believes that our intellectual decline as a race has much to do with adverse genetic mutations. But human intelligence is suffering for other reasons as well.

 

According to Crabtree, our cognitive and emotional capabilities are fueled and determined by the combined effort of thousands of genes. If a mutation occurred in any of these genes, which is quite likely, then intelligence or emotional stability can be negatively impacted.

Further, the geneticist explains that people with specific adverse genetic mutations are more likely than ever to survive and live amongst the ‘strong.’ Darwin’s theory of ‘survival of the fittest’ is less applicable in today’s society, therefore those with better genes will not necessarily dominate in society as they would have in the past.

While this hypothesis does have some merit: are genes really the primary reason for the overall cognitive decline of the human race? If humans really are lacking in intelligence more than before, it’s important to recognize other possible causes. Let’s take a look at how our food system plays a role in all of this.

It’s sad, but true; our food system today is contributing to lower human intelligence across the board.

Researchers from Harvard have found that a substance rampant in the nation’s water supply, fluoride,  is lowering IQ and dumbing down the population. The researchers, who had their findings published in the prominent journal Environmental Health Perspectives, a federal government medical journal stemming from the U.S National Institute of Environmental Health Sciences, concluded that ”our results support the possibility of adverse effects of fluoride exposures on children’s neurodevelopment”.

One study published in the Proceedings of the National Academy of Sciences found that pesticides, which are rampant among the food supply, are creating lasting changes in overall brain structure — changes that have been linked to lower intelligence levels and decreased cognitive function. Specifically, the researchers found that a pesticide known as chlorpyrifos (CPF) has been linked to ”significant abnormalities”. Further, the negative impact was found to occur even at low levels of exposure.  Read more:

I wonder what some of our ancient philosophers would think about our intelligence if they were to visit us right now?

Would we have an easy time understanding them or would they, for the most part, be talking over our heads?
