Big heads often have many friends

One study demonstrated that people with large skulls often have more friends than others.

Telegraph reported that scientists at Oxford University in England investigated the relationship between brain size and the number of friends of 40 university graduates and the same age. Research subjects have equal opportunities in communicating with fellow people. The research team asked 40 people to list the number of contacts or contact with friends - not counting colleagues, friends on social networks or business partners - that they have done in the last 7 days.

Volunteers then do a test of other people's understanding of thinking, an important skill in people's social life.

The results show that people with large brains have more friends than those who own small brains, and the ability to maintain their relationships is also better.

"We conclude that individuals with more friends perform neurological activities better than those with few friends. In addition to the volume of the forehead area - their eye drives are also larger , " said Professor Robin. Dunbar, the lead researcher, said.

The forehead cortex - the eye socket is located in front of the skull and above the eyes. People use this cortical region to think higher.

"Understanding the relationship between human brain size and the number of friends will help us find mechanisms that make humans possess larger skulls than other primates," Dunbar explains.

"The size of the frontal brain regions of the human skull has increased dramatically in the past half a million years," the team said.

Dunbar said the time spent on social relations, personality, gender, and place of residence are factors that influence the number of friends of each person. However, neurological skills also play an important role in maintaining social relationships.

"Our research shows that the ability of people to understand thoughts will help people maintain many friendships , " the professor said.
