"The key to engaging empathy is what has been called “the identifiable victim effect.” You can see the effect in the lab.
The psychologists Tehila Kogut and Ilana Ritov asked some subjects how much money they would give to help
develop a drug that would save the life of one child... The answers were about the same. But when Kogut and Ritov
told a third group a child’s name and age, and showed her picture, the donations shot up...
If a planet of billions is to survive, however, we’ll need to take into consideration the welfare of people not yet harmed
—and, even more, of people not yet born. They have no names, faces, or stories to grip our conscience or stir our fellow-feeling.
Their prospects call, rather, for deliberation and calculation. Our hearts will always go out to the baby in the well;
it’s a measure of our humanity. But empathy will have to yield to reason if humanity is to have a future"
