THL researcher Jarmo Salo says that nearly half of Finnish children would, under WHO guidelines, be regarded as having outsize heads. The average Finn’s head is among the largest 10-15 percent of heads in WHO data.
Unfortunately for big-headed Finns, larger heads do not mean brainier children.
“Intelligence is not correlated with large heads at all,” says Salo.
What the use of a large head if it can't has brains?
