Smarter Babies Have Oversized Heads

Babies with big heads are more likely to be smarter and be more successful later in life, a study has shown.
Babies born with large heads were more likely to receive degrees and score higher on some test.
The average baby head in the U.S. is 13.5" - 14", so if your baby's head is larger than this it is considered to be more intelligent in its later years.
"A large cranium could simply be a reflection of a bigger-than-average-headed mom or dad. One thing is for certain, it’s not an indication of a learning disorder or disability," experts note.
In a paper published by the Nature journal Molecular Psychiatry, researchers said: 'Highly significant associations were observed between the cognitive test scores in the UK Biobank sample and many polygenic profile scores, including . . . intracranial volume, infant head circumference and childhood cognitive ability.'
'In addition to there being shared genetic influences between cognitive skills and some physical and mental health states, the study also found that cognitive skills share genetic influences with brain size, body shape and educational attainments,' Professor Deary told Neuroscience News.
The researchers analysed data from around 100,000 people held in the UK Biobank.
