Interesting article on how we navigate through life in packs or small group of people.
Look around. Packs of humans are everywhere. Clusters of people riding escalators. People standing in for groups in ticket queues. Mothers ordering meals for children at restaurants. Families clearing immigration together at airports. Groups of people playing sports. Packs backstop all of social reality. When other levels of social reality unravel and fail, pack realities get stronger. Your emergency preparedness plan — for floods, earthquakes, hurricanes or whatever is the big risk in your neck of the woods — is almost certainly a pack-level plan that includes family, neighbors, and friends. Pack realities are much stronger in countries, like India, where higher levels of social reality are particularly weak.
