Whenever you see a person wearing glasses, you might automatically regard them as more intelligent, but this sounds rather stereotypical. A recent research has just proved this conviction is right, since glass wearers are actually more intelligent than other people. The study also offered a deep insight into the genes that influence these cognitive traits.
Glass wearers really tend to be more intelligent
A team of researchers from the University of Edinburgh wanted to see if glass wearers sport some genetic differences. This way, they selected a number of 44,480 people and took a close look at their genes. This way, they found some interesting connections between their features and their visual capacities.
Those people who scored higher in terms of intelligence had 30 percent more chances to be glass wearers. On the contrary, those with poorer scores in terms of IQ didn’t really need a pair of glasses to be able to read. The study also revealed some other encouraging things about intelligent people.
The study was the first complex analysis of intelligence
This research was the first one to take a close look at intelligence traits and other genetic features related to them. Apart from glass wearing, intelligence seems to influence other genes as well. Smart people seem to have some other genes that influence heart health in the positive sense.
The study was so complex since it looked at a number of 148 genes related to cognitive abilities. From all these 148, 58 haven’t been studied before, so the results really bring a new perspective on the matter. If researchers keep exploring these connections, they might find out why a person’s cognitive performance drops as they reach a certain age.
However, the study was rather observational. Therefore, not all glass wearers are automatically intelligent or have a great cardiovascular health. What the study did was offer a better perspective on the genetic traits of intelligence and how one might inherit them. This paper was published in the journal Nature Communications.
