Moreover, they also had 30 percent less likely chances to experience an acute depressive disorder, and had 17 percent higher chances to live longer. Scientists explored how an individual's hereditary traits may impact their cognitive function.
In what is believed to be the largest genetic study into cognitive function, researchers in Scotland drilled down into data on over over 300,000 people in North America, Europe and Australia to identify genes associated with intelligence.
The research team from the University of Edinburgh analyzed genetic information of over 300,000 individuals from existing genomic databases, "in which participants submitted samples for DNA analysis, answered questionnaires, and underwent tests created to give a measure of their general cognitive ability", according to Science Alert.
The data came from previous studies with participants ages 16 to 102 who had been asked to take several tests that measured general cognitive ability.
"This study, the largest genetic study of cognitive function, has identified many genetic differences that contribute to the heritability of thinking skills", said Gail Davies from University of Edinburgh in the UK.
Researchers examined 148 genomic regions related to better cognitive function, including 58 that have not previously been reported. In short, the bailiffs also have their health gambling.
Among their findings was that those with higher levels of intelligence were more likely to need reading glasses than those with lower scores.
Lead researcher professor Ian Deary said the discovery of gene patterns relating to cleverness could help scientists further research diseases such as Alzheimer's.
However, the researchers said there was no proof of a defined link between the two factors.
