Working cooperation helps people be smarter

Compared to human ancestors, 'smart people' have bigger brains - a mystery that scientists have always wanted to explore. According to researchers in Ireland and Scotland, the answer may be social interaction that helps our brains evolve.

Working groups help people grow more

Experts believe that working with others helps people survive, but people must have brains big enough to deal with all complex problems in society.

Through a computer model, the team recreated the human brain, allowing the neural cell network to evolve in response to a range of social challenges. There are 2 hypothetical situations that are given. One is that two accomplices are arrested by police, they must decide whether to denounce the partner or not. Two, two people are stuck in a car amidst the snow, to consider whether to work together to free themselves or let the other person do it alone. In two cases, selfish people benefit more.

However, researchers discovered when the brain evolved, people tend to choose to cooperate.'We often cooperate with others, which requires us to be able to see who is doing something for us and help ourselves to change our behavior accordingly' , the researcher rescue Luke McNally, explaining that working cooperation and brainpower 'feed each other' . He said that cooperation also contained contemplation. For example, if other people cooperate and you cheat them, the next time they work together, they may think: 'He tricked me, I will not cooperate with him.' 'So basically, you have to cooperate to get cooperation later,' McNally concludes.
