Summary: Despite tallies of Facebook friends or Evites in inboxes, loneliness happens. It can strike us while we’re dining at a table of one, taking a long solo journey, or even while we’re with family and friends. The lonely feel more depressed, more deeply addicted, and are more easily angered. Why does loneliness hit and why does it hurt? Humans have evolved, thanks to the long period of abject dependency of our offspring, as social beings, with brains wired for communication and empathy. Forming and maintaining social connections—from romantic partners to families, communities, cities, and civilizations—is essential to our survival. John Cacioppo, director of the Center for Cognitive and Social Neuroscience at the University of Chicago and co-author of Loneliness: Human Nature and the Need for Social Connection, visited Zócalo to discuss the evolutionary basis of human relationships and why they matter.
