Part of it, Keltner thinks, is that poor people must often band together to make it through tough times ―a process that probably makes them more socially astute. He says, "When you face uncertainty, it makes you orient to other people. You build up these strong social networks." When a poor young mother has a new baby, for instance, she may need help securing food, supplies, and childcare, and if she has healthy social times, members of her community will pitch in. But limited income is hardly a prerequisite for developing this kind of empathy and social responsiveness. Regardless of the size of our bank accounts, suffering becomes a conduit to altruism or heroism when our own pain compels us to be ____________________ other people's needs and to intervene when we see someone in the clutches of the kind of suffering we know so well.
