I don't know if you've heard the elders say, "this child has a big head and will be very smart when he grows up.". Is the person with big head necessarily smart? Is this statement based on science? Let's have a look with sihai.com.
Why do people with big brains be smart? Is it true that big heads are smart?
In the animal world, apes are among the best in intelligence, but their brain weight is far less than that of humans. However, in terms of brain weight, humans are not second to none. The brains of whales and elephants are several times heavier than human beings, but their intelligence is far less than that of human beings.

Why do people with big brains be smart? Is it true that big heads are smart?
Anthropologists in the former Soviet Union used an index to indicate the development of the brain: the larger the index, the more developed the brain. The index of human beings is much higher than that of all animals. Of course, this is not to say that a big head is always smart.
In fact, there are many sulci gyri in the brain that increase the area of the cerebral cortex and the number of cells in the cerebral cortex. Therefore, a small brain does not necessarily have fewer brain cells, and a large brain does not necessarily have many brain cells. What's more, a person's intelligence depends largely on his education and training.
