As bizarre as it may sound, researchers have found that there may be a correlation between a child's cranial circumference and intelligence; children born with big heads seem to be more likely to achieve success in life. Keep reading to find out why babies with big heads are more likely to do well in life.
Investigating the possible correlation. A recent study has found that babies born with big heads are more likely to be intelligent. A child's cranial circumference has been linked to academic achievement later in childhood.
The study. The discovery was made during research on the link between genes, IQ, and health. Researchers from the University of Edinburgh studied 100,000 British people who were assessed on their physical and cognitive skills and submitted to an in-depth interview on their backgrounds and lifestyle. People born with larger head circumferences, say the researchers, scored higher on verbal-numerical reasoning tests and had enhanced cognitive skills.
Higher education. According to research by the University of Edinburgh, babies with big heads are likely to be more intelligent and to also earn an advanced degree. The researchers stumbled across the findings while investigating the link between genes, IQ, and health.
Cognitive test scores. The study which was published in the Journal of Molecular Psychiatry said that the data showed significant links between cognitive test scores, “intracranial volume,” and “infant head circumference.” Evaluating the physical and cognitive condition of 100,000 Britons, the study also found that babies born with larger heads grow into healthier adults.
Health and life expectancy. The link between health and intelligence has been made before and researchers say that there is a genetic link between how the body manages disease and how smart you are. Previous research concluded that people with lower IQs were less healthy than those with higher IQs and that more intelligent people have a longer life expectancy.
The key 17 genes. Researchers were also able to identify 17 genes which they say play a significant role in brain function and have an important part to play in physical and mental health in humans. Our cognitive skills share genetic influences with aspects of our physical and mental health, says Professor Ian Deary, who led the research, and also share others with the size of the brain and the shape of the body.
UK Biobank. The data which was collected by the UK Biobank, which stores data on more than half a million people between the ages of 37 and 73, threw up some many findings, that researchers said at the time that it was impossible to discuss all the implications. The blood, urine, and saliva of the study’s participants were also collected for future analysis.
Other indicators. There are other ways to tell whether your baby is very intelligent, studies have found. One indicator is the memory, they say, with infants who remember past events, likely to be smarter than their peers who cannot.
