A specific set of neurons deep in the brain may motivate us to seek company, holding social species together.
As social animals, we depend on others for survival. Our communities provide mutual aid and protection, helping humanity to endure and thrive. “We have survived as a species not because we’re fast or strong or have natural weapons in our fingertips, but because of social protection,” saidJohn Cacioppo, the director of the Center for Cognitive and Social Neuroscience at the University of Chicago. Early humans, for example, could take down large mammals only by hunting in groups. “Our strength is our ability to communicate and work together,” he said.
But how did these powerful communities come to exist in the first place? Cacioppo proposes that the root of social ties lies in their opposite — loneliness. According to his theory, the pain of being alone motivates us to seek the safety of companionship, which in turn benefits the species by encouraging group cooperation and protection. Loneliness persists because it provides an essential evolutionary benefit for social animals. Like thirst, hunger or pain, loneliness is an aversive state that animals seek to resolve, improving their long-term survival. View Original Article»
