Genetics Impact on Intelligence

Einstein

Was Einstein a genius because he inherited good genes?  That is just one of the questions some new research may be able to determine.  According to the article A Genetic Code for Genius in the Wall Street Journal, “In China, a research project aims to find the roots of intelligence in our DNA.”

There is no denying that emotional intelligence has become a buzz word in HR.  Employees’ emotional quotient or EQ may sometimes be more important than their IQ.  However, the roots of many personality and intelligence issues like IQ still remain a mystery.  According to the Wall Street Journal article, “Studies show that at less half of the variation of intelligence quotient, or IQ, is inherited. Truly important genetics that affect normal IQ variation have yet to be pinned down.”

The average person has an IQ of 100 and Nobel laureates have an average IQ of 145. In a study of intelligence in China, the researchers are looking at individuals who have an IQ of over 160.  To date, studies have not been large enough to give very useful information about IQ and genetics.  This latest study “will compare the genomes of 2,200 high-IQ individuals with the genomes of several thousand people drawn randomly from the general population.”  The problem is finding the people with such an extremely high IQ.  The researchers likened it to finding a bunch of people over 6-foot-9 inches tall.
