A recent study has examined the genetic influence on intelligence, and the results concerning academic aptitude are surprising.
Usually, most parents and teachers assume that children will discover more of a natural flair for writing, or science, or math, or reading. However, research shows that genes don’t determine aptitude in one particular subject. Genes determine the general aptitude, and the difficulty or extraordinary ability some people have with one subject is most likely caused by environmental factors.
A team of researchers from King’s College London investigated the connection between genes and academic success. They analyzed genetic data from 12,500 twins, half of which were identical. They then compared it to the subjects scores on standardized tests in math, science, language, art, English, and business.
The results showed that 54 to 65 percent of the differences in scores in all subjects were accounted for by a genetic predisposition. However, environment accounted for 12 to 21 percent of the differences in score.
“There’s a general academic achievement factor. Children who do well in one subject tend to better in another subject and that is largely for genetic reasons,” said the study’s first author Kaili Rimfeld.
