It is the gap between the relationships you want and the ones you actually have. John Cacioppo read that sensation as a deficit signal from the same family as hunger and thirst, built to hurt precisely so that it pushes us back toward people. This post covers what more than eighty years of the Harvard Study of Adult Development found and where that study reaches its limits, the commuter train experiments showing that a short conversation with a stranger lifts your mood, and why adult friendship is structurally hard along with what actually helps.
